DIAGNOdent is a powerful new laser technology used for early detection and diagnosis of tooth decay. DIAGNOdent helps locate decay that is very small or hidden in the cracks and crevices of teeth. This allows us to treat the decay when it is small, requiring less removal of the 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.
