Hi my teeth are extremely worn down i am only 21 but my teeth are really sensitive and sore. can i have this fixed? and roughly how much to fix

Bruxism ?: If you're grinding your teeth excessively, premature wear can occur. You'll need to see a local dentist for a fee estimate.. impossible to discuss fees without actually seeing you and radiographs of your teeth. Too many variables and not enough info given.

Dental exam: Your wear can be treated but you would need to be evaluated by a dentist to find out the extent of your problem and your treatment options. This cannot be done on line.

Tooth wear: Important to determine and treat the cause of the tooth wear. Cannot treatment plan or cost estimate in this forum. You will have to be examined and treatment planned by a Restorative Dentist or a Prosthodontist.

See your Dentist: Your dentist is the best person to diagnose your condition and prescribe a treatment. The cost depends on what’s needed. Most dentists offer payment plans and at your age it important to fix this before it becomes a lot more complicated and expensive.
