Composite veneers feel too thick/bulky in my mouth, can they be thinned out?

If you have not gotten used to them in over a month, and they still feel too bulky and you are having speech problems, they most likely are too bulky.  Since you are having problems with your speech, the length of the veneers may be incorrect or the veneers may have been extended to the lingual surface and too much bulk may have been added.  Your dentist can thin them down and  make adjustments to have your speech return to normal.

I would recommend consulting your dentist regarding these composite veneers. These restorations can be polished and adjusted as needed as long as they are not too thin to chip.
