Root Canal Treatment

Pain Free Root Canals

Many of our patients fall asleep during root canal treatment, without sedation, due to the painless procedure. When we finish, they often comment on how painless and easy it was.

To put it in a simple way, a root canal treatment is just like doing a deep filling. It just takes a little longer to do.

Our CARING DENTIST with GENTLE AND CAPABLE hands will cruise you through Root Canal treatment with peace of mind.

Review By Our Patient

After suffering through a bad root canal 40 years ago, I have been AFRAID of going to the dentist. Dr. Gruber was a very good dentist, but when it came to "root canal's" I always choose to pull the tooth. Guess what... I was in pain and Dr. Wang recommended a "root canal". I was so afraid, I was shaking. Dr. Wang was very kind to me. Explained it all to me, and told me it wont hurt, and he could save the tooth. Well guess what.... HE WAS RIGHT !!! It was easy, and most of all PAINLESS. Dr. Wang Thank You !!! After suffering years of fear, I'm starting to think going to the dentist isn't that bad after all. I would highly recommend Dr. Wang to those of you living in fear of the dentist. Dr. Wang makes it easy. Thank you again, Happily looking forward to seeing you in 6 months. (and that's a first !!)

More About Root Canals


Your teeth are meant to last a lifetime. Years ago, diseased or injured teeth often were pulled. But today, even if the pulp inside one of your teeth is injured or infected, the tooth often can be saved through root canal treatment.

What happens if the dental pulp is injured?

The pulp is soft tissue inside the tooth that contains blood vessels and nerves. When the pulp is diseased or injured and unable to repair itself, it dies. The most common causes of pulp death are a cracked tooth, a deep cavity, problems with large fillings, or serious injury to the tooth. All of these can allow bacteria to enter into the pulp.

Why should the pulp be removed?

If the problem pulp is not removed, the tissues around the root of the tooth can become infected, often resulting in pain and swelling. Even if there is no pain, bacteria can damage the bone that anchors the tooth in the jaw. Without treatment, the tooth may have to be pulled.

Removing a tooth can create problems

When a tooth is pulled and not replaced, the teeth around it may shift from their normal position. Shifted teeth may make biting and chewing difficult and may make it harder to clean your teeth. They may also make it harder to clean your teeth. Areas that are not cleaned well are more likely to get gum disease.

Root canal treatment can prevent these problems by saving your natural tooth. A natural tooth is almost always better than a replacement tooth. Nothing looks, feels or functions like the natural tooth--and being able to chew and enjoy your favorite foods will keep you healthy and confident. Also, a root canal is usually less expensive than a replacement tooth.

What does treatment involve?

Root canal treatment involves one or more visits. There are several steps that your dentist or endodontist will perform to save your tooth:

  • First, your tooth is numbed for your comfort. The dentist will put a thin sheet of latex rubber over your tooth to keep the tooth dry. An opening is made through the crown of the tooth into the pulp chamber.
  • The tooth's nerve or pulp is then removed from both the inside of tooth (pulp chamber) and the root canal (the space inside the root). Each root canal is cleaned and shaped so it can be filled.
  • Medicine may be placed in the pulp chamber and root canal to help get rid of bacteria.
  • A temporary filling will be placed in the opening of the tooth to stop saliva from getting into the chamber and root canals. You might also be given antibiotics if infection has spread beyond the end of the root(s). If your dentist prescribes medicine, use it only as directed. If you have any problems with the medicine, call your dentist. 
  • During the next stage of treatment, the temporary filling is removed. The root canals are usually filled with a rubber-like material to seal them.
  • In the final step, the tooth may be restored by a crown or a filling to strengthen it and improve the way it looks. If an endodontist performs the root canal treatment, he or she will usually recommend that you return to your general dentist for this step.
It is very important to follow your dentist's directions in setting up your appointments so your root canal treatment is successful.
