Bruxism, or grinding and clenching of the teeth, is a common condition that often goes undiagnosed.
Understanding bruxism
Unmanaged bruxism will lead to long-term irreversible wear and damage and the need for complex restorative treatment.
In some cases bruxism is self-diagnosed but in many cases it is diagnosed by others (such as a partner who hears the grinding during the night) or by a dental professional who notices evidence such as worn-down teeth or fractures of the teeth or dental restorations.
Stressful life events, altered mood, sleep disorders (such as restless leg syndrome and sleep apnoea), smoking, alcohol, caffeine, and some prescription or recreational drugs are risk factors contributing to bruxism. However, many individuals suffer from bruxism without a clear cause.

- Joint pain or tenderness in the jaw
- Jaw muscle discomfort, facial pain, or earache

- Poor quality sleep
What are the causes of TMD?
Temporomandibular Joint (TMJ)
TMJ refers to the temporomandibular joint, which is a hinge that connects your jaw to your skull bones in front of each ear. It lets you move your jaw up and down and from side to side, so you can talk, chew and yawn. It is one of the most complicated joints in the whole human body.
Pain and problems associated with the TMJ is characterised by severe clicking, pain from chewing hard foods, pain during dental treatment, locking and reduced ability to open your jaw.
Muscle Dysfunction
Muscle dysfunction can result in TMD and is a result of clenching habits throughout the day and while asleep. Symptoms are characterised by:
- pain or muscle tenderness around the jaw muscles, which can develop into persistent pain
- headaches or migraines which can appear upon waking up and develop throughout the day
- weak jaw muscles causing you to avoid certain foods due to difficulty chewing
Bite/Occlusion
TMD can be caused by occlusal or bite dysfunction. This is the result of worn or fractured teeth due to misalignment, or tooth-on-tooth contact, which can be habitual, genetic or pathological. If left untreated, it can wear away the enamel which can lead to tooth sensitivity and decay.
Trauma
TMD can be caused from previous trauma of the TMJ such as motor car accidents or sports injuries.
A blow to the head can cause damage to the jaw joints along with the skull. Whiplash, or anything that impacts how you carry your head on the top of your neck, can cause jaw problems.
