Occlusal adjustment — also called selective occlusal equilibration — is a procedure that modifies the contact points between the upper and lower teeth to redistribute bite forces more evenly. At Dazzle Dental Clinic, it is used as part of treatment for bite-related problems including TMD symptoms, post-restoration bite interference, and bruxism management. It is not a standalone treatment for all jaw or bite complaints; understanding when it is and is not appropriate is essential for patients evaluating this option.
What the Procedure Involves
The clinician first identifies which teeth are making contact first, hardest, or at incorrect angles using articulating paper (a thin marking film bitten between the teeth) and/or a digital occlusal analysis system (T-Scan) that maps force distribution across the arch. Areas of premature contact, heavy unilateral load, or working/non-working side interferences are identified.
Selective grinding (selective enamel reduction) removes small amounts of enamel from the identified contact points using fine rotary instruments. The amount removed is minimal — typically 0.1–0.5mm — and the enamel surface is repolished to prevent sensitivity. This is irreversible: once enamel is removed, it does not regenerate. Each adjustment is re-tested with articulating paper or T-Scan before further reduction. The session ends when the contact pattern shows even bilateral simultaneous contact in the planned position.
When Occlusal Adjustment Is Clinically Appropriate
After restorative work: a new crown, veneer, or composite that is even slightly high creates a premature contact that loads the restored tooth excessively. Adjustment of the restoration (or opposing tooth if indicated) is routine and indicated at every delivery appointment. For the biomechanics of how unmanaged load affects implants specifically, see our occlusal load management guide.
TMD symptom management: bite interferences that create non-working side contacts or deflective contacts on closure can contribute to masticatory muscle overactivation. In appropriately selected TMD cases, occlusal adjustment reduces the muscular trigger. However, the evidence that occlusal adjustment alone reliably resolves established TMD is limited — it is most effective combined with splint therapy and physiotherapy when significant TMD is present.
Bruxism: occlusal adjustment does not stop bruxism — bruxism is a central nervous system-mediated parafunctional activity that is not driven by peripheral occlusal factors. Adjustment can reduce specific wear facets and improve load distribution, but a nightguard remains the primary protective management for bruxism patients.
What Occlusal Adjustment Cannot Fix Alone
Structural bite discrepancies (skeletal malocclusion, significantly malaligned arches) require orthodontic correction or orthognathic surgery — not occlusal grinding. Significant TMD with disc displacement or condylar pathology requires a comprehensive multi-modal approach. Missing posterior teeth causing bite collapse require tooth replacement before occlusal adjustment produces stable results. The multi-disciplinary planning approach at Dazzle ensures these interactions are addressed in the correct sequence.
At Dazzle
Occlusal analysis using T-Scan is available, providing quantitative force distribution data rather than relying solely on articulating paper marks. This allows precise identification of high-load contacts and objective before/after comparison. Adjustment sessions are followed by a review appointment to confirm the occlusal change has been maintained and to assess the clinical response.
FAQs
Q1: Will I feel the enamel removal during occlusal adjustment?
Performed on vital (non-root-canal-treated) teeth: some patients experience brief transient sensitivity during polishing. Local anaesthesia is not routinely required. For patients with significant sensitivity, topical desensitising agents are applied after adjustment.
Q2: How many sessions of occlusal adjustment are needed?
For post-restoration adjustment: usually one session at the delivery appointment, with refinement at the review. For comprehensive equilibration: typically 1–3 sessions depending on the extent of occlusal discrepancy, with at least one week between sessions to allow neuromuscular adaptation to each change.
Q3: I grind my teeth — will occlusal adjustment help?
Occlusal adjustment may improve how your teeth wear under grinding by redistributing the load, but it will not reduce the grinding frequency or intensity. A properly fitted nightguard is still the primary management. Combining both — a well-adjusted bite and a nightguard — gives the best protection for the teeth and restorations.
Q4: Is occlusal adjustment the same as having teeth filed down?
The amount of enamel removed in occlusal adjustment is much less than laypeople typically imagine — 0.1–0.5mm, compared to the 1.5–2mm removed for crown preparation. The intent is targeted removal of specific contact points, not global reduction of tooth height. Visible tooth shape change from occlusal adjustment is uncommon.
