How does teeth clashing against one another affect enamel?

Bruxism: Clenching and grinding your teeth can wear down enamel, tooth colored fillings and micro-fractures that will enlarge over time causing large "chunks" of your tooth to break off.

It can wear down.: It will over time wear down. It varies from person to person. It is related to your bite, bruxing, habits, tmj, bleaching, orthodontics and current dental work & materials that are in your mouth. The enamel will wear down, chip & require repair. See a pankey or dawson bite equilibration trained dentist, who can help you with your bite issues.

Mechanical wear: "teeth clashing" or grinding or "bruxism" cause damage to the tooth enamel by the mechanical action of one tooth against another. Something has to give or break. This mechanical action cause microscopic fractures and wear of the teeth.

LOOK FOR WEAR: Mashing of teeth can be very damaging.

Clashing: Any improper contact between teeth in both jaws can lead to excessive stress on the gums/bone supporting the teeth, cause excessive wear, cause fractures or abfractures. See your Dentist. Your bite may have to be adjusted via orthodontic tooth repositioning or reshaping of the teeth. As a stop-gap measure, a night guard may prevent damage while you sleep.
