What is the best option for enamel defect? Veneers, lumineers, or any alternatives? (photo)

Enamel defects negatively impact the bonding strength of composite resins. Depending on the extent of the defects I would recommend porcelain veneers if the defects were minimal but would opt for full ceramic crowns if the defects were undermining the integrity of the enamel on a larger scale. In the former case I would be concerned that the veneers might delaminate and come off.

Because you have this enamel defect, porcelain crowns are preferred over laminates as your teeth need full protection from breaking and further erosion.

Your case is not a complicated treatment. It does not matter if you have this enamel problems it can be easily fixed with porcelain veneers or crowns. In your particular case I would recommend crowns, since porcelain veneers are extremely thin and probably you will be able to see the yellowish (because of the translucent material)With the crowns no one will notice you have that color below, a gum contouring would be necessary on upper posterior as well. With crowns we can change the bite height, we can change each tooths size, shape, color, etc. We can design what you want and what can work for you. All cna be done in 10 days, I hope this helps.
