Teeth crystals, or tooth gems, are small flatback rhinestones that are adhered to the tooth using a professional dental glue or gel.

Gems on teeth are semi-permanent and can last anywhere between 6 months to one year, depending on the quality of the adhesive used and the aftercare given.

Yes, both Swarovski and Preciosa crystals are lead free so can be used to decorate teeth.

Gems can be easily removed from your teeth by a professional dentist, using a tool to take the crystal off, then a polishing tool to fully remove any leftover adhesive.

Tooth gems range from around £2.50 for a pack of 4 stones, depending on the brand. Swarovski tooth gems are more expensive, but for less money and equal sparkle, Preciosa crystals are a great option.
