What are the Signs and Symptoms of Teeth Grinding?


Bruxism A common issue that affects up to 80% of the population, the grinding of teeth and clenching of the jaw can cause tooth wear, breakages, pain, limited movement of the jaw joint (temporomandibular joint disorder), migraines and headaches. Most common in adults over 25 years old, the cause is not fully understood, though symptoms often worsen during stressful periods. One of the most debilitating effects of bruxism is headaches, migraines and chronic tension headaches. These symptoms often go untreated because who would think that it is caused by tooth grinding or clenching? Effects of bruxism Bruxism sufferers are affected in many ways and it can lead to more serious issues, often requiring a dentist's intervention. Many symptoms, however, are unlikely to be dental related; often bruxism is left untreated for many years. It is common for patients to turn to their GP and have a magnitude of investigations for other medical conditions, including MRI and brain scans.

During sleep, there is no feedback mechanism to tell your brain that your teeth are hurting because of too much pressure, hence we can put up to 40 times the amount of pressure on our teeth whilst we sleep - it is no surprise to see a lot of damage.
