I’ve been whitening my teeth for several weeks with a home whitening kit. The last few days, though, I’ve started having a zing of pain that lasts for several seconds and then stops. It is always on the tooth where I had a dental bonding repair quite a few years ago. Could the teeth whitening be eating away at the dental bonding?

Dear Nadia,
Teeth Bleaching Trays
I am sorry for the pain you are experiencing. The good news is I do not think teeth whitening is damaging the dental bonding. There has never been any evidence that whitening gel does any damage to bonding agents and it both have been around for a while, as well as used together. The more likely scenario is that a part of your dental bonding has come off leaving part of the tooth exposed and sensitive.
I am assuming that you are doing this home teeth whitening under the supervision of your dentist. My recommendation is you pause the whitening for a few days, call your dentist and let him know what is going on. He can track down where the exposure is and place a protective agent there to re-cover the spot. Then you can continue with your teeth whitening as you normally would, but this time pain free.
You should be aware that dental bonding doesn’t last as long as something like porcelain veneers. For something like a small chip repair, that is fine. Just know that you will need to replace it at some point or it will begin to pick up stains. When it does, teeth whitening won’t fix it. The whitening agents only work on natural tooth structure. The bonding will just have to be replaced.
I hope this helps.
