A dental crown is a tooth-shaped cap that restores a decayed, broken, weak or worn-down tooth. Dentists also use crowns to cover dental implants and root canal-treated teeth. Made from a variety of materials, including metal, resin and porcelain, crowns last between five and 15 years with proper care.  At Cochituate Smile Center, we look forward to assisting you in finding a comfortable and permanent solution to your dental issues and putting you on a path toward renewed oral and overall health.
