In a Root Canal Treatment the nerve endings of an infected tooth are removed or made inactive so that infection cannot spread further. Generally a root canal treatment is followed by a crown fitting to restore the teeth shape.
Sometimes the teeth may be so decayed- either due to usage over a period of time, accident or lack of proper care, that it is better to remove all of them. That is when a full denture replacement may be recommended.
Implants are placed in place of tooth to fill the gap that a decayed or broken tooth may have left. Dental Implants are the best way to restore the right shape of teeth as well as provide sound foundation to the tooth.
