Bruxism or teeth grinding is common. Due to grinding teeth enamel of teeth wear off and overtime dentin will expose.some times micro cracks will appear after prolonged grinding teeth.These may cause teeth sensitivity.
TMJ or temporomandibular joint is connection between lower jaw to skull.
TMD or temporomandibular disorder ,which is any disorder that affects or is affected by deformity,disease,misalignment,or disfunction of the temporomandibular articulation. This includes occlusal deflection of the temporomandibular joints (TMJs) and the associated response in the musculature.
If the chewing muscles or the joint itself are causing you pain you may have temporamandibular disorder, or TMD. It can be caused by stress, continual clenching of the jaw muscles, or teeth grinding.
Some of the symptoms of TMD are:
- Pain during opening or closing mouth
- Difficulty chewing
- Locked jaw
- Jaw Clicking or popping
Many of these symptoms can often be associated with other health problems, so only a medical professional can tell you if it is due to TMD. Teeth grinding is an especially problematic symptom because it can lead to further problems. Prolonged teeth grinding, or bruxism, can cause enamel to wear off teeth and expose dentin ( Attrition). This material is softer than enamel and more susceptible to decay. Sensitivity to hot and cold food or drink may also develop from excessive teeth grinding.
If you suspect you may have TMD come in for a consultation. We can help diagnose you and provide relief for your symptoms. Pain relievers and hot/cold compresses are short term methods to provide relief for pain symptoms. A night guard can be used to help prevent or lessen the effects of teeth grinding at night. This can lead to a more permanent solution. In very severe cases of TMD surgery may be required, but behavioral treatments to change the way you use your jaw muscles are usually enough to provide relief.
Clarification of terminology :
Attrition : it is wear due to tooth-to-tooth friction, this is result from bruxism.
Abrasion : It is wear due to friction between a tooth an exogenous agent like chewing on a food bolus or from tobacco chewing.
Erosion : It is tooth surface loss due to chemical action like GERD.
Abfraction: The role of occlusal overload on non-carious cervical lesions on teeth.
