Root Canal Therapy

Are you in almost unbearable pain from a tooth? Or maybe there’s just this nagging sensitivity? You may have an infected root canal.

Dr. Robert Hawke can perform a root canal to relieve the pain and eliminate the infection so it doesn't return or spread.

If you are concerned about a tooth or are in severe pain, call anytime to seek emergency care in Tucson, AZ.

Are You in Pain?

You don't have to be! Dr. Hawke in Tucson is available virtually any time patients have an emergency. He once even performed a root canal treatment for a patient on Christmas Day. If you are in pain, call (520) 323-3842 and he will see you as soon as possible. 

Early Signs You May Need a Root Canal

Pain is a clear signal that you may have an infected root canal. However, even without pain, there are early warning signs you should not ignore. Intervening early lets you avoid the pain a root canal can inflict. If you notice the following symptoms, call to have our dentist, Dr. Hawke, examine your tooth and root canal with an x-ray: 

  • Toothache or discomfort while chewing
  • Lingering sensitivity to heat or cold
  • Swelling in your gums or face
  • Sudden but persistent bad taste in your mouth
  • A pimple on the gum
  • A loose tooth

Common Questions

X-ray of teeth

The Pain Stopped. Do I Still Need Treatment?

Yes. While the pain may stop without treatment, an infected root canal will not heal on its own. In fact, a sudden lack of pain may mean the nerves inside the tooth have died. Once bacteria reach a tooth's interior, the pulp needs to be removed and the inside disinfected by a dentist. Left untreated, you could lose the tooth and in extreme cases, the root canal infection can spread to your jaw, brain, and blood.

Can My Tooth Be Saved?

Early 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. However, if the tooth is too damaged, the only 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. 

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 Pain 

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 less uncomfortable than a standard dental filling.
