Do your jaw muscles feel tired when you wake up, or do you notice yourself clenching your teeth while working? Bruxism is one possible explanation. It is activity of the chewing muscles that can include clenching or grinding the teeth, either during sleep or while awake. Mild cases do not always need treatment, but the effects on your teeth and jaw are worth checking.
Signs you might notice
These can include worn tooth edges, repeated damage to fillings, sensitivity or tight facial muscles. Sometimes a partner notices the sound of grinding first. Tooth wear alone does not prove that grinding is happening now. The wear may be old, and other processes can also damage teeth.
What to discuss at your appointment
Notice when the tension occurs and whether you also have sleep difficulties. Bring a list of your medicines. Your dentist will assess the teeth, restorations and muscles, and ask about daily habits. Symptoms suggesting a sleep disorder may need a separate medical assessment.
What a splint can and cannot do
A fitted splint can help protect teeth from damage. It does not automatically remove the cause of clenching. Management depends on the symptoms and may involve changing habits or addressing factors related to sleep or stress. Do not stop prescribed medication yourself, even if you suspect a connection.
Before buying a ready made mouthguard, ask whether it suits your situation. Pain or difficulty opening the mouth needs assessment rather than tooth protection alone.
