DIAGNOdent is a powerful new laser technology used for early detection and diagnosis of tooth decay. DIAGNOdent helps locate decay that is nearly invisible to the naked eye or that is hidden in the cracks and crevices of teeth. This allows us to treat the decay early, requiring less removal of the natural tooth structure. This allows the tooth to maintain its strength, and be less likely to crack or break easily in the future. Early decay detection means an easier and less costly treatment for you.
