Buffalo Root Canal Therapy

Roughly 14 million people undergo root canals each year. Even a hairline crack can allow bacteria to penetrate the pulp and infect the nerve itself, so almost any trauma to the tooth requires some form of advanced therapy. If left untreated, the damaged tooth can cause major complications.

Buffalo Root Canal Retreatment

Despite the best efforts of Buffalo dentists and endodontists, root canal procedures do not always remove all debris and bacteria from around the pulp, because most teeth have so many micro-thin cracks and crevices. In these cases, endodontic re-treatment is often the best option.

Traumatic Dental Injuries in Buffalo

If only the surface of the tooth is chipped or cracked, a filling or reattachment usually restores the tooth. But if the pulp is exposed, a Buffalo endodontist probably needs to perform a root canal and use more aggressive treatment options.

Buffalo Pulpotomy / Pulpectomy

A child’s kiddy root canal or baby root canal is called a pulpotomy or pulpectomy. Common factors of damaged pulp in children include tooth decay or traumatic injury. A Pulpotomy, or Pulpectomy helps to treat, repair, and save the affected tooth.  Let our Buffalo Endodontist gently treat your child.

Buffalo Apicoectomy

Even after a root canal, bacteria can remain deep inside crevices that are very difficult for even experienced dentists to reach. In these cases, an apicoectomy is often the best choice, as this procedure literally confronts the root of the problem.

Digital Imaging in Buffalo

In nearly all cases, effective diagnosis is a key to effective treatment. With cutting-edge Cone Beam Computed Tomography (CBCT) scanners, we can use 3D images to plan minimally-invasive and cost-effective corrective procedures.

Highly recommend!
