A. If your teeth haven’t had root canal treatment then the trauma to them is not as bad as it could have been in which case the teeth should last a significant amount of time. It can be difficult to tell you for sure without seeing the teeth or an x-ray. If bonding has been done then veneers or wrap arond porcelain crowns should be a treatment option.
Can your dentist not give you an estimate on how long the teeth will last. If you are unsure with the treatment you have received you could seek an opinion from a restorative dentist. Go to someone who is used to carrying out cosmetic treatments. Ask to see a portfolio so that you can see examples of their work.
If these teeth do eventually fail there is alsways the option of having implants so you may not have to face having false teeth
