Tooth gems are applied by a dental professional using safe dental materials or dentistry glue. The gem is bonded to the enamel of your tooth, and no drilling is involved in the process. The application is similar to placing orthodontic braces or brackets on a tooth. You will be asked to wear glasses to protect your eyes while they shine a blue light onto the adhesive and tooth gem. This blue light, along with a fan, helps to cure the adhesive and create a long-lasting bond between your tooth and the gem.
