A sensation of discomfort or an unnatural feeling experienced upon biting down after the placement of a dental crown indicates a potential issue with the restoration. This sensation can manifest as pressure, pain, or a feeling that the bite is uneven. For example, an individual might report that only one side of their mouth seems to be contacting when chewing, or that they are experiencing tenderness in the jaw.
Addressing such sensations promptly is crucial for maintaining oral health and preventing further complications. Ignoring these feelings could lead to jaw pain, temporomandibular joint (TMJ) disorders, or damage to the crown itself or opposing teeth. Historically, dentists have relied on articulating paper and patient feedback to identify and correct bite discrepancies related to dental restorations. This feedback is vital for the long-term success and comfort of the dental crown.
The subsequent sections will delve into the possible causes of bite-related discomfort following crown placement, the diagnostic procedures used to identify the issue, and the various treatment options available to alleviate the unpleasant sensation and restore proper occlusion. These considerations will focus on both newly placed crowns and those that have been in place for a longer duration.
1. High point
A “high point” on a dental crown refers to an area of the crown’s occlusal surface (the biting surface) that makes premature contact with an opposing tooth during occlusion. This premature contact prevents the teeth from fitting together properly. The sensation directly correlates with the feeling that the crown feels “weird” when biting down. The presence of a high point disrupts the natural distribution of occlusal forces. The affected individual is likely to experience excessive pressure on the crowned tooth. This sensation can range from a mild awareness of contact to significant discomfort or pain. For example, a patient might report feeling like the crown is the only tooth touching when they close their mouth.
The identification and correction of a high point are paramount. Failure to address a high point can lead to several complications. It can cause temporomandibular joint (TMJ) issues due to altered bite mechanics. It can induce tooth sensitivity from the concentrated force on the affected tooth. It can result in fracture of the crown or the opposing tooth. The dentist typically uses articulating paper to mark the point of premature contact. Subsequent adjustments are made to the crown to reduce the height of the interfering area. This ensures a balanced and even distribution of occlusal forces.
In summary, the existence of a high point is a common cause of the disconcerting sensation experienced after crown placement. Correcting this discrepancy through precise occlusal adjustments is vital for the long-term success of the restoration and the preservation of the patient’s oral health and comfort. The clinicians attention to detail during crown fabrication and cementation is essential to prevent such issues. The patients prompt reporting of unusual sensations is critical for timely intervention.
2. Improper fit
An ill-fitting dental crown is a significant factor contributing to the sensation that the restoration “feels weird” when biting down. This discrepancy between the crown and the prepared tooth structure can manifest in various ways, leading to discomfort and potential long-term complications.
-
Marginal Discrepancies
Marginal discrepancies refer to gaps or overhangs at the interface between the crown margin and the tooth. These imperfections can trap bacteria, leading to inflammation of the gingiva (gums) and potential periodontal disease. The patient may experience tenderness, bleeding, or a persistent dull ache. For instance, food impaction in the marginal area can create pressure during biting, resulting in an unnatural feeling and discomfort.
-
Inadequate Contact Points
Proper contact points between adjacent teeth are essential for maintaining arch stability and preventing food impaction. If the crown’s contact points are too tight or too loose, it can disrupt the normal distribution of occlusal forces. A tight contact may cause pressure sensitivity when biting, while a loose contact can lead to food getting lodged between the teeth, creating discomfort and a “weird” sensation. A crown that is not properly contoured to the adjacent teeth can cause many problems.
-
Internal Misfit
Internal misfit describes the lack of precise adaptation between the crown’s inner surface and the prepared tooth structure. This discrepancy can create spaces where bacteria can colonize, leading to recurrent decay and potential endodontic (root canal) issues. Furthermore, the lack of intimate contact can compromise the crown’s retention, making it feel unstable or “off” when biting down.
-
Occlusal Disharmony
An improperly fitted crown may not integrate harmoniously with the opposing teeth during occlusion. This occlusal disharmony can result in uneven distribution of bite forces. This can lead to localized pressure, temporomandibular joint (TMJ) pain, or tooth sensitivity. The patient may experience a sensation of the crown being too high or too low during biting movements, causing a persistent feeling that something is not right.
In conclusion, the multifaceted nature of an improper fit highlights the importance of precision during crown fabrication and cementation. Marginal discrepancies, inadequate contact points, internal misfit, and occlusal disharmony all contribute to the overall sensation of the crown “feels weird” when biting down. Addressing these issues requires careful evaluation and adjustments to ensure optimal crown fit, function, and patient comfort. An experienced dental professional is best suited to diagnose and address these concerns.
3. Inflamed Tissues
Inflamed tissues surrounding a dental crown significantly contribute to the sensation of discomfort or unnatural feeling experienced upon biting. The inflammatory response alters sensory perception and disrupts the normal function of the supporting structures, leading to the impression that the crown “feels weird.” The following facets detail the underlying mechanisms of this phenomenon.
-
Gingival Inflammation
Gingival inflammation, or gingivitis, is a common condition where the gum tissue becomes irritated and inflamed. Poor crown margins or improper crown contours can exacerbate this inflammation by trapping bacteria and debris. The resulting swelling and tenderness of the gingiva directly affect the perception of bite forces, making the crown feel higher or more prominent than it actually is. For example, even slight pressure on the inflamed gums during chewing can generate a disproportionate pain response, altering the overall sensation of the bite.
-
Periodontal Ligament Involvement
The periodontal ligament (PDL) is a complex network of fibers that connects the tooth to the alveolar bone. Inflammation of the PDL, known as periodontitis, can occur due to ill-fitting crowns or excessive occlusal forces. This inflammation changes the proprioceptive feedback from the tooth, affecting the individual’s ability to accurately sense bite forces. As a result, the crown may feel unstable or as if it’s shifting during chewing, contributing to the sensation of it being “weird.”
-
Pulpal Irritation
In some cases, crown preparation or cementation can cause irritation to the dental pulp, the nerve-containing tissue within the tooth. This irritation can lead to pulpal inflammation, resulting in increased sensitivity to pressure and temperature changes. Even normal biting forces can stimulate the inflamed pulp, creating a sharp or throbbing pain that is perceived as originating from the crown. This heightened sensitivity significantly alters the patient’s perception of the crown’s fit and function.
-
Muscle Spasms
Chronic inflammation in the tissues surrounding a crown can reflexively lead to muscle spasms in the jaw. Inflammatory mediators can irritate nearby muscles and cause them to spasm. This can lead to bite changes and occlusal disharmony, thereby disrupting the normal bite and occlusal scheme. These altered bite forces result in the crown feeling weird upon biting down.
These facets illustrate that inflamed tissues play a crucial role in the altered sensation experienced when biting on a crown. The inflammatory processes affect the sensory feedback from the gums, periodontal ligament, and dental pulp, distorting the perception of bite forces and leading to the disconcerting feeling that the crown is not fitting or functioning correctly. Effective management of these inflammatory conditions is essential for restoring proper bite function and alleviating the uncomfortable sensation.
4. Bite interference
Bite interference, or occlusal interference, following the placement of a dental crown is a primary cause for the subjective sensation that the crown “feels weird” when biting down. This interference disrupts the natural and harmonious contact between the upper and lower teeth, leading to altered proprioception and discomfort.
-
Premature Contact
Premature contact occurs when the crown makes initial contact with an opposing tooth before the other teeth come together. This focused pressure creates a sensation of the crown being too high, leading to uneven bite force distribution. For example, an individual might experience discomfort only when biting down on a specific area of the crown, or a feeling that the crown is the only point of contact between the upper and lower teeth. This can lead to strain in the temporomandibular joint (TMJ) and surrounding muscles.
-
Lateral Interference
Lateral interference arises during sideways or protrusive jaw movements. The crown might impede smooth gliding of the teeth, creating friction or locking. This can be perceived as a grinding or catching sensation, making the crown feel unnatural during chewing or speaking. An example of lateral interference is when the crown prevents the canines from properly guiding the bite during lateral excursions.
-
Protrusive Interference
Protrusive interference occurs when the crown hinders the forward movement of the jaw. This typically manifests as a distinct contact on the crown as the front teeth attempt to engage. Individuals experiencing this interference may find it difficult to bite into foods with their front teeth, or they may develop an altered jaw posture to avoid the point of contact. In these cases, the unnatural contact creates a sense of unease or discomfort that translates to the crown feeling “weird.”
-
Loss of Occlusal Support
If the crown’s occlusal anatomy does not properly support the bite, there can be a redistribution of force to other areas in the mouth. This lack of support can lead to over-eruption of opposing teeth, shifting of adjacent teeth, and uneven wear patterns. Consequently, the patient may experience a general feeling of instability or imbalance in their bite, directly impacting the perception of the crown’s fit and function.
The diverse forms of bite interference highlight the importance of precise occlusal adjustments following crown cementation. Addressing these interferences is critical for restoring a balanced and harmonious bite. Failure to correct bite interferences can lead to TMJ disorders, muscle pain, tooth sensitivity, and long-term complications. Proper management will ensure long-term comfort and function of the crown.
5. Cementation issues
Cementation issues during the placement of a dental crown frequently contribute to the patient’s perception that the restoration “feels weird” when biting down. Inadequate cementation can result in several problems affecting the crown’s stability, occlusion, and overall comfort. When the cement does not properly bond the crown to the prepared tooth structure, microscopic gaps can form at the margins. These gaps allow for microleakage of bacteria and fluids, potentially leading to sensitivity, recurrent decay, and inflammation of the surrounding tissues. For example, if a patient experiences sharp pain upon biting down on a newly cemented crown, it may indicate that the cement has not adequately sealed the margins, exposing the underlying dentin to external stimuli.
Furthermore, improper seating of the crown during cementation can directly impact the occlusal relationship, causing bite interference. If the crown is not fully seated, it may be positioned too high relative to the adjacent teeth, resulting in premature contact and uneven distribution of occlusal forces. As a result, the patient may experience a feeling that the crown is the only point of contact when biting down, or that their bite is unbalanced. Moreover, some cements shrink during setting, which can lead to the crown becoming slightly loose over time. This lack of firm retention may cause the crown to shift or move slightly during function, creating a sense of instability and discomfort. Cement selection is also critical, some cements cause post operative sensitivity.
In summary, cementation issues significantly influence the perceived comfort and function of a dental crown. The failure to achieve a complete and secure cement seal can lead to a cascade of problems, ranging from sensitivity and inflammation to bite discrepancies and instability. Thorough attention to proper cementation techniques, including appropriate material selection, meticulous seating procedures, and careful removal of excess cement, is crucial for minimizing these complications and ensuring a positive long-term outcome. Regular dental checkups can also identify and address cementation-related issues early, preventing further problems and maintaining the overall health and integrity of the restored tooth.
6. Nerve sensitivity
Nerve sensitivity following the placement of a dental crown is a significant factor contributing to the sensation that the crown “feels weird” when biting down. This heightened sensitivity can stem from various factors related to the preparation and cementation process. The patient is experiencing altered sensory feedback from the affected tooth.
-
Pulpal Inflammation
Pulpal inflammation, or pulpitis, occurs when the dental pulp (the nerve-containing tissue inside the tooth) becomes irritated or inflamed. This can happen during the crown preparation process if excessive heat or pressure is applied to the tooth. Even with careful technique, the pulpal tissue can be impacted. The resulting inflammation increases the sensitivity of the tooth to external stimuli, such as pressure from biting. A patient might experience a sharp, shooting pain when biting down on the crown, or a lingering ache following the pressure.
-
Exposed Dentinal Tubules
During crown preparation, a portion of the dentin (the layer of tooth structure beneath the enamel) is exposed. The dentin contains microscopic tubules that lead directly to the dental pulp. If these tubules are not adequately sealed after crown cementation, they can become sensitive to temperature changes, osmotic pressure, and mechanical stimulation. This sensitivity can manifest as a sudden, stinging pain when biting down on the crown, especially if the biting force is concentrated on a particular area of the tooth.
-
Occlusal Trauma
If the newly placed crown is too high or does not fit properly with the opposing teeth, it can cause occlusal trauma, leading to nerve sensitivity. The excessive force on the crowned tooth can irritate the periodontal ligament and inflame the pulp. The increased pressure triggers pain receptors within the tooth, creating the sensation that the crown “feels weird” or uncomfortable when biting. Over time, occlusal trauma can result in chronic nerve sensitivity, requiring further intervention.
-
Cement Irritation
Certain dental cements used to secure the crown can sometimes cause irritation to the dental pulp, leading to nerve sensitivity. Some cements contain acidic components that can penetrate the dentinal tubules and trigger an inflammatory response. This pulpal irritation can result in a heightened sensitivity to biting forces, making the crown feel unusual or painful when pressure is applied. The choice of cement and proper isolation techniques are essential to minimize this type of irritation.
These facets illustrate how nerve sensitivity can profoundly impact the perception of a dental crown’s fit and function. Whether due to pulpal inflammation, exposed dentinal tubules, occlusal trauma, or cement irritation, the heightened sensitivity alters the patient’s experience of biting on the crown. Addressing these issues requires careful diagnosis and appropriate treatment to alleviate the nerve sensitivity and restore a comfortable, functional bite.
7. Crown instability
Crown instability, characterized by a lack of secure and immobile fixation of the restoration to the prepared tooth, is a significant contributor to the subjective sensation of a dental crown “feels weird” during biting. The connection stems from the disruption of normal proprioceptive feedback and occlusal forces. When a crown is not firmly cemented or experiences cement degradation over time, it can exhibit subtle movements during function. These movements, even if minor, are registered by the sensitive mechanoreceptors in the periodontal ligament. Consequently, the individual experiences an unusual or shifting feeling upon biting. The tooth feels “off” or as if it is not properly integrated into the bite.
The consequences of crown instability extend beyond a mere subjective sensation. The instability may result in uneven stress distribution across the tooth and supporting structures. The tooth is subject to abnormal forces, increasing the risk of fracture of the crown, the underlying tooth structure, or both. Further, the shifting crown margins create opportunities for bacterial microleakage, leading to secondary caries and potential pulpal involvement. Clinically, an example would be a patient reporting the feeling of the crown “rocking” slightly when chewing firm foods. The clinician would identify this mobility upon examination, confirming the presence of crown instability and the correlation with the patient’s reported unusual sensation.
In summary, crown instability is a critical factor in the etiology of the “crown feels weird” sensation. The altered mechanics and sensory feedback associated with instability disrupt the normal bite and function of the tooth. Addressing this issue requires careful evaluation of crown adaptation, cement integrity, and occlusal forces to ensure a stable and functional restoration. The long-term success of a dental crown depends on maintaining a secure and immobile bond to the underlying tooth structure, preventing the development of crown instability and the associated uncomfortable sensations.
8. Jaw muscle strain
Jaw muscle strain, resulting from overuse, misuse, or compensation for occlusal discrepancies, can significantly contribute to a patient’s perception that a dental crown “feels weird” when biting down. The intricate relationship between the masticatory muscles and dental occlusion dictates that any imbalance or strain in the muscles can alter sensory feedback and functional movements of the jaw.
-
Altered Proprioception
Jaw muscle strain can affect proprioception, the body’s ability to sense its position in space. Strained muscles may send distorted signals to the brain regarding jaw position and bite force, causing a patient to perceive the crown differently. For example, strained muscles may pull the mandible into an unnatural position during closure, leading to premature contact on the crown and a sensation that it is “high.”
-
Compensatory Muscle Activity
When a crown interferes with the natural bite, patients may subconsciously adjust their jaw posture or chewing patterns to avoid the interference. This compensatory muscle activity can lead to strain in the temporalis, masseter, or pterygoid muscles. The resulting muscle fatigue and discomfort can manifest as a general feeling of tension or imbalance in the jaw, which is then associated with the crowned tooth. If a newly placed crown prevents a patient from closing their teeth comfortably on one side, they may favor the other side, straining the muscles on the working side.
-
Referred Pain
Jaw muscle strain can also cause referred pain, where discomfort is felt in a location different from the actual source of the problem. The pain may be referred to the teeth, including the crowned tooth, making it feel sensitive or achy when biting. A patient with temporomandibular joint dysfunction (TMD) may experience pain radiating from the jaw muscles to the crowned tooth, interpreting this discomfort as a problem with the crown itself.
-
Changes in Occlusal Force Distribution
Muscle strain can lead to changes in how forces are distributed across the teeth during biting. Strained muscles may not contract evenly, leading to uneven pressure on different teeth. This altered occlusal force distribution can cause the crowned tooth to feel overloaded or unstable, contributing to the sensation that it “feels weird.” This occurs when, due to muscle imbalances, the bite forces are not equally distributed across the dental arches but are concentrated on a specific area, such as the crowned tooth.
In conclusion, jaw muscle strain plays a significant role in the sensation of a dental crown “feels weird” during biting by altering proprioception, causing compensatory muscle activity, referring pain, and changing occlusal force distribution. Addressing muscle strain through therapies such as physical therapy, occlusal adjustments, or medications can help restore proper muscle function and alleviate the discomfort associated with the crown.
9. Occlusal changes
Occlusal changes, defined as alterations in the alignment and contact between teeth, frequently contribute to the sensation that a dental crown “feels weird” when biting down. These changes can occur gradually over time or as a result of dental procedures, directly impacting the distribution of occlusal forces and sensory feedback within the oral cavity.
-
Tooth Migration
Tooth migration refers to the shifting of teeth from their original positions due to factors such as tooth loss, periodontal disease, or parafunctional habits. When adjacent or opposing teeth migrate, the occlusal contacts on a crowned tooth can be altered, leading to premature contacts or a lack of support. For instance, if a tooth opposing the crowned tooth over-erupts, it can cause excessive pressure on the crown during biting, leading to discomfort and the sensation that the crown is too high. The new contacts cause the crown to feel weird.
-
Attrition and Abrasion
Attrition and abrasion are the gradual wear of tooth structure due to tooth-to-tooth contact and external factors (e.g., abrasive foods, improper brushing). As natural teeth wear down, the occlusal forces can shift and concentrate on the crowned tooth, especially if the crown is made of a harder material than the surrounding teeth. This uneven distribution of forces can create sensitivity or a feeling of instability on the crowned tooth, making it feel unnatural during biting. The different rate of wear causes the patient to complain of the crown feeling “different.”
-
Temporomandibular Joint Disorders (TMD)
TMD encompasses a range of conditions affecting the temporomandibular joint and surrounding muscles. TMD can lead to changes in the bite due to muscle spasms, joint inflammation, or displacement of the articular disc. These occlusal changes can impact how the teeth, including the crowned tooth, contact during function, causing pain, clicking, or a sensation of the bite being misaligned. The jaw no longer closes evenly and causes the crown to feel as though it is in the way.
-
Postural Alterations
Changes in body posture can indirectly affect the bite. The intricate relationship between the cervical spine, head position, and mandibular posture dictates that alterations in posture can influence occlusal contacts. A forward head posture, for example, can cause the mandible to shift forward, leading to premature contact on anterior teeth or altered occlusal forces on posterior teeth, including the crowned tooth. In these situations, individuals might describe their bite as feeling “off,” with the crown feeling more prominent than before. This new bite changes the patients experience of the crown.
These examples demonstrate that occlusal changes, whether resulting from tooth migration, wear, TMD, or postural shifts, can significantly influence how a dental crown feels during biting. By understanding the mechanisms underlying these occlusal changes, dental professionals can more effectively diagnose and address the causes of discomfort and restore a stable, harmonious bite, thereby alleviating the feeling that the crown “feels weird”. Regular dental evaluations are crucial to monitor occlusal stability and prevent or manage these issues.
