Should I replace Veneer with Lumineer? My teeth have been ground down, but I don't want them ground down any more.

New technologies in porcelain can get veneer thickness down to .3 of a millimeter.  Lumineers can look nice but traditional veneers always look better.

Unfortunately, with your teeth ground down, there are few other options than getting traditional veneers. Lumineers also tend to have mixed results. It takes a great deal of skill to do them properly, and if they are too thin, they can end up being quite delicate and break easily. Without the proper tooth structure to reinforce them, this risk is greatly increased. Lumineers are designed as an alternative to traditional veneers, that require minimal or no reduction of your teeth to place.As your teeth are already ground down, you most likely need to get traditional veneers. I would recommend finding a dentist who specializes in cosmetic dentistry, in particular porcelain veneers, who can make thinner porcelain veneers that are both strong and fit properly with your teeth. Lumineers; however, are an option for your other teeth that have not been ground down if you want to proceed down that road.
