Should I be concerned with this extra tooth in my gum? (photo)

Discolouration of teeth can be caused by intrinsic or extrinsic factors. Intrinsic discolouration occurs when there are changes that occur in the internal structure of the tooth. Common causes of intrinsic discolouration presenting as grey lines or diffused grey colours: 1. Tetracycline staining This commonly occurs amongst patients whose mothers took tetracycline (an antibiotic) during their pregnancy, or amongst patients who consumed tetracycline when they were children (typically 0 - 8 years in age). Tetracycline deposits stain the tooth structure throughout its growth. 2.

There are very few situations where there is no need to remove some bulk from the tooth to fit veneers. You have large gaps in between your teeth. Your teeth are already thinned down from previous fillings or acid erosion (you must still have enamel covering the tooth surface for predictable long-term bonding). If BOTH of these criteria exist, then it may be possible to have porcelain veneers without much trimming. Trimming tooth structure for veneers achieves 2 functions: Creates an end-stop for the porcelain to end and to allow easier seating of the veneer.
