My question would be how much can you really grind on a vital tooth to be able to add much
metal to the area to laser weld?
If tooth had receded pulp chamber, that might be possible, but if not, and pt is sensitive, then
DDS might end up grinding your beautifully repaired/welded area and you might get the blame
when the repair fails and have to do it a second time around for free . . . . might be best to
return, or better yet, reply now before accepting work, with a strong disclaimer.
My 2 cents.
