When replacing bonding, many times you can leave the deep layer that is on the enamel as long as it is not discolored or full of stains or decay.

The old material should be totally removed because I have found things hiding underneath too many times like decay or stains.  Don't worry about enamel abrasion because the new bonding or veneer you are getting will cover it and protect it as well.  Your dentist will also be very careful only to remove what is necessary.

It is best to remove all old materials to be certain everything is clean and decay free.  But if the underlying bonding is not too old or discolored and an adequate bond can be obtained, some of the existing bonding material can be left.

I prefer to remove all remnant of any old dentistry and place new dentistry over solid and real tooth structure.  I have a microscope that helps precise drilling.  I hope that helps.  Dr. David Frey

This depends on if you are talking about a deep filling or cosmetic bonding on a natural tooth.On a filling I agree with those who remove all the old bonding to ensure that their is no decay underneath.  That being said if it is extremely deep, then sometimes a judgment call will be to leave a thin layer that covers the nerve.  You can sometimes repair bonding that is done for cosmetics and not remove all the old bonding.  However, I think a stronger bond is obtained by removing the old bonding.  Hope this helps clarify things.

Leaving old bonding under new one.

I have no problem leaving some of the old boding in the deepest parts of the tooth. However, the new bonding should cover the enamel in order to get maximum strength.

When replacing bonding it is ok to leave decay in the deepest parts as long as their is no decay or discoloration around the part that you are leaving
