Tooth gems can last up to 6 to 24 months, depending on their style. Swarvoski Crystals, Brilliance Crystals and Shaped Crystals have better adhesion on the enamel by the special glue, hence last up to 24 months. Real Gold Charms and Real Diamonds have less adhesion due to their weight and can last up to 6 months. With extra care, they may last even longer. This period is different for each client, as it depends on the enamel levels of the tooth along with the aftercare of the gem. You can also have a jewel applied as a temporary enhancement that lasts from 1-6 weeks.
