DIAGNOdent is an effective new laser technology used in early discovery and diagnosis of tooth decay. DIAGNOdent helps find decay which is virtually invisible to the naked eye or that is hidden in the crevices and cracks of teeth. This permits us to take care of the decay early, requiring much less elimination of the original tooth structure. This enables the tooth to retain its strength, and be less likely to crack or break easily later on. Early decay detection usually means an uncomplicated and less expensive treatment for you.
