Root canal therapy is used to salvage a severely injured, cracked or decayed tooth when the soft tissue in the root canal has become inflamed. If not treated properly, the tooth abscesses. We use a virtually painless technique for removing the infection and sterilizing the inside of the root canal, saving the healthy outer part of the tooth. After restoring the tooth with a dental crown, it will function like any other tooth, a tooth that, with good hygiene, can last a lifetime.
