Hello. I have some tooth abrasion issues at the gumline for which I received a type of bonding (I'm not sure which) on a few teeth about 7 years ago.
Last month, the bonding became darkly discolored on one tooth, and the dentist that I now go to says the bonding must be redone. I'm not sure why it suddenly became discolored, but it is. He says he will use a different type of bonding (I'm not sure which) that is more durable than what I was given years ago.Can you please tell me the types of bonding available for gumline erosion/abrasion, and which types are the best? Thank you!
