I hesitate about the DNA App b/c my narrow arches are hereditary & they moved back after widening in grade school. Dad has same narrow arches. Also I am dating again and eager to have wider smile ASAP and assume I can't do the DNA after getting veneers. Also, since they will be in the back of mouth should I just get comp.e bonding or non-porcelein veneers? (PS I have an overbite but will just deal with it). How many veneer should I get? 2 each side top & bottom? Or 4? Should get the DNA App 1st?
