Hello, no matter what kind of plastic surgery you do to your teeth, it will hurt your teeth more or less. For example, when washing teeth, the exposed dentin is not handled properly, and the teeth will become sensitive. When doing porcelain restoration, it is sometimes necessary to grind off good teeth before inserting new ones. In addition, the porcelain teeth in dental plastic surgery have a certain life, so it is not advisable to bite hard objects, otherwise it may break porcelain.
