Unless a partner complains about your nighttime noise, it is difficult to know if you are grinding your teeth when you sleep.
Some clues:
Unexplainable headache, especially early morning or evening
Waking or fatigued face or muscles when you wake up
Difficult sleep
Extreme cold sensitivity in your mouth
Click or pop up chin
The front teeth look clearer, brittle, or become uneven
Teeth, or molars, can stress teeth and bones. In addition to the issues listed above, grinding can cause teeth and bones to retract and open the gums to age and become infected, Mello said.
The most effective treatment is to fit your dentist to your mouth. It may cost hundreds of dollars, but some may be covered by insurance.
