Common Questions About Root Canals

What Is Root Canal Therapy?

Root canal therapy is an endodontic treatment designed to extract infected pulp from inside your tooth, as well as the nerves connected to it. Your dentist, Dr. Robert Hawke, will then fill and seal the area. After that, he will place a filling or a custom, natural-looking crown for a healthy, uniform smile.

What Causes Root Canal Damage?

Root canals need treatment if an infection, cavity, or tooth decay is are present. When treated in a timely manner, the bacteria can be removed, preventing long-lasting side effects throughout your mouth and body.

Can My Tooth Be Saved?

Early dentistry treatment can likely save your tooth and let you avoid seeing an endodontist for advanced procedures. If the infection has not caused extensive structural damage and decay, Dr. Hawke can sterilize the inside cavity of the tooth and restore its strength with a crown. If the tooth and pulp are too damaged, the only endodontic alternative is the extraction of the compromised tooth. In most cases, Dr. Hawke then would recommend a dental implant to replace the missing tooth and avoid bone loss in your jaw. A root canal procedure will let you avoid this more complex dental work. 

The Pain Stopped. Do I Still Need Treatment?

Yes. You still need root canal treatment by a dentist because an infected root canal will not heal on its own. Once bacteria reach a tooth's interior, the pulp needs to be removed and the inside disinfected by a dentist. The pain may stop without treatment, but this just indicates the nerves inside the tooth have died. Left untreated, you could lose the tooth and in extreme cases, the root canal infection can spread to your jaw, brain, and blood.

Same-Day Crowns after Root Canal Therapy

Dr. Hawke uses CEREC® technology, a high-tech milling unit, to create dental crowns while you wait. Patients love the convenience of undergoing root canal therapy and walking out with a natural-looking crown in one convenient visit.

The Root Canal Procedure

Dr. Hawke's advanced dental techniques and experience make undergoing root canal therapy comfortable and effective without the added expense of seeing an endodontist. Dr. Hawke began practicing in 1976 and his Tucson, AZ, practice has treated generations of families. 

To assess your tooth, Dr. Hawke will take an x-ray to confirm infection in the root canal. The dentist will then numb the area with topical anesthesia. A hole is made in the tooth to access the inner pulp chamber. The dentist will remove the bacteria-infected nerves, blood vessels, and connective tissue in the pulp. Next, he will sterilize the chamber to prevent a second infection. Finally, he will fill the interior with a rubber-like substance to fortify the tooth. 

In most cases, a crown will be placed on the tooth to protect it from further damage and strengthen it. To ensure the crown blends in with your other teeth, Dr. Hawke uses high-grade porcelain that mimics the translucency of a natural tooth. 

I'm Worried About Root Canal Pain

Does Root Canal Treatment Hurt?

Often, when patients think about root canal therapy, the word "painful" comes to mind. In actuality, root canal therapy eliminates the pain and is no more uncomfortable than a standard dental filling.
