Hello, no matter what kind of dental plastic surgery is done to the teeth, the teeth will be damaged to some extent. While teeth scaling removes tartar, the exposed dentin is not treated and the teeth will become sensitive. When doing porcelain dental restorations, it is sometimes necessary to grind down the good teeth to fit new teeth. In addition, when porcelain teeth are repaired during dental plastic surgery, the porcelain teeth themselves have a certain lifespan, and it is not advisable to bite hard food, otherwise the porcelain may be broken.
