Gentle Root Canal Treatment

A root canal saves a badly infected tooth and relieves the pain, and with modern techniques it's often no less comfortable than a filling.

About root canals

The pulp inside a tooth contains nerves and tissue. When it becomes infected, it can cause pain, swelling and even tooth loss if left untreated. A root canal removes the infected pulp and cleans the inside of the tooth so you can keep it.

Thanks to local anesthetic and modern dentistry, root canals are highly tolerable. Once treated, the tooth is usually restored with a crown so it looks natural and works normally. Most root canals are successful and last many years, even a lifetime.

What to expect

Numbing

Local anesthetic is used so the tooth is fully numb before we begin.

Cleaning

The infected pulp is removed and the inside of the tooth is cleaned.

Sealing

The tooth is filled and sealed; an antibiotic may be prescribed if needed.

Restoring

A crown is placed to protect the tooth and restore its appearance.

Common questions

Does a root canal hurt?
The procedure is done with local anesthetic and is often no more uncomfortable than a filling. It's usually the infection beforehand that hurts. Treatment relieves it.
What is recovery like?
Some sensitivity for the first few days is normal. You can brush and floss as usual once treatment and restoration are complete.
