Generally, the process of applying veneers does come with some pain. Depending on the type of veneers that you and your dentist have agreed on, there may be minimal to no pain involved in the process. Porcelain veneers will involve the most potential for pain as it is more invasive than composite resin veneers. Luckily, the process of grinding down a thin layer of tooth enamel during the application of porcelain veneers is less painful with the application of a local anesthetic.
So, to sum it all up, the process of veneers can involve some level of discomfort. Still, with a careful and knowledgeable dentist, the process will be as streamlined and comfortable as possible.
