Is there a limit to how many times a tooth can be refilled?+
There is no fixed count. It depends on how much sound, supportable structure is left and on the cause of the earlier failures, both of which your dentist can assess.
Why does replacing a filling tend to make it bigger?+
Removing an old restoration takes material along with it and may also involve some tooth structure. Any decay or cracking discovered at that stage can add to the area involved.
Should I switch to a crown instead of filling it again?+
A crown may make sense when cusps are weak or damage is widespread. If enough support remains, something smaller could be appropriate, so ask your dentist to explain the reasoning for your tooth.
Could my bite be the reason my fillings keep failing?+
It could be one factor. Grinding, clenching and contact patterns influence how restorations hold up, together with size, bonding, hygiene and new decay.
What if the tooth cannot be restored predictably?+
Your dentist would describe that frankly and go through what alternatives exist for your situation. The conclusion depends on an examination, so it is not something to assume ahead of time.
How do North Kildonan residents book an assessment of a repeat problem?+
Use the form or call the clinic, and mention that the tooth has been repaired before. Your visit takes place on McPhillips Street, and the clinic will reply to confirm a time.
