Sensitive teeth can have various causes, ranging in severity from 'minor' to 'serious'. Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.
Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms. In order to diagnose sensitive teeth, we could:
Are your teeth sensitive or tender?
Possible responses:→ No / don't know
→ One or two teeth, occasionally
→ One or two teeth often / several occasionally
→ One or two teeth most of the time / several often
→ Several teeth, most or all of the time
Many people are unaware that they clench or grind their teeth while asleep. Signs can include sensitive or even chipped teeth.
