I’ve been doing teeth whitening for a week and a half and it was going fine until yesterday. I keep feeling this painful zap that lasts about 30 seconds then goes away. It is always in the area of where I had some composite bonding done for some damage to the tooth some years ago. Could the teeth whitening be damaging the bonding?
Teeth whitening does not affect dental bonding. If the bonding had failed, the repair would have just fallen off. You mentioned that this bonding is a few years old. The more likely scenario is that the bonding is nearing the end of its lifespan. I would pause your teeth whitening and then have your dentist look at it. It is very likely that some of the composite is worn and that is exposing part of the tooth.
If that is the case, your dentist can simply repair the composite bonding and then you will be able to take up your whitening again after the repair. It is good that you are doing your whitening under the care of your dentist. Because of that you will have protection from unnecessary complications.
Once the exposed part of your tooth is covered again, you should not have any more pain while you are whitening.
