Clenching and grinding your teeth, also known as bruxism, is very common and can lead to pain, sensitivity and destruction of your teeth.
Some signs and symptoms that you may be clenching or grinding include:
audible teeth grinding in your sleep
wear on all the teeth
waking up with dull headaches
sore jaw
generalized teeth sensitivity
fatigue from lack of sleep
Over time, bruxism can lead to loss of enamel, broken or chipped teeth, and sometimes loss of teeth.
