Hello,

I had bonding done to correct gaps between my front 2 teeth and the
surrounding teeth (6 total) approx 7 years ago. Now due to a chip on
one of the bonding as well as a general "breaking down" of the bonding
it needs to be rebonded or replaced. According to my dentist it will be
impossible to repair the chipped area without it looking patched due to
differences in the age of the material, coloring, etc. He has offered
either rebonding of the 6 teeth or 6 porcelain crowns as my
alternatives. I had a few questions and I would appreciate the input of
posters on this forum.

First, how is the debonding procedure done? Is the material simply
removed with a drill or sanding tool? How long do you think this
procedure would take?

Secondly, I was told I was not a candidate for porcelain veneers due to
the fact that some of my teeth were bonded on the back of the tooth
also, or needed to be. I didnt fully understand this when the dentist
said it and I wondered if anyone could clarify it for me.

I would like the seemingly more durable option of crowns, however from
what I gather it is a very involved procedure with a relatively large
amount of tooth structure removal necessary. I would ideally like to
get veneers.. lumineers look like an interesting option. What are your
opinions on those?

Thanks for your time and input!
