Tooth jewellery, or tooth gems are tiny, decorative attachments that are bonded to the teeth with the same adhesive used for brackets for braces. It was big trend in Sweden in the late '90s and early '00s.
Tooth jewellery comes in a variety of colors, sizes, and even shapes. It can be made out of gold, diamonds, glass stones or just diamante.
The application process is a simple and safe cosmetic procedure, which is best performed by a dental professional. The dental jewellery is bonded onto the tooth in the same way as an orthodontic bracket. It won't damage the tooth or remove any tooth structures, and doesn't need any special maintenance. It can last for years or longer.
If you don't like it at any point, the gem and adhesive material can be removed without damaging the tooth.
