The mere mention of a root canal is enough to strike fear into the strongest of hearts. Realistically though, a root canal is a nearly painless procedure if carried out by a dentist who is properly trained and experienced. A root canal is a useful tool that can help to resolve your pain issues while keeping your natural teeth.

Root canals are usually performed when:

  • There is an infection in the nerve of a tooth
  • There is damage to pulp (the soft inside of the tooth)

During a root canal your dentist will removed the damaged part of your tooth. Next your tooth is completely cleaned then sealed off so that no bacteria can enter. If you are diligent about taking care of your teeth, and see your dentist regularly, root canals can be avoided.

If you think you may need a root canal, there are four possible symptoms that you should watch for:

  • Your tooth has tenderness and possible swelling near the surrounding gums.
  • You experience severe pain while eating or upon the application of any pressure.
  • Your tooth is extremely sensitive to hot/cold temperatures even once the temperature has been removed from the tooth.
  • Your tooth is discolored.

If you do need a root canal, the following will take place:

  • Your dentist will take and examine your X-rays to see how far the infection has spread.
  • Your dentist will give you local anesthesia to numb the area surrounding the infected tooth.
  • Your dentist will attach a rubber dam to the infected tooth to keep it dry and clean.
  • Your dentist will drill a small access hole in the infected tooth so that all pulp, nerve tissue, and bacteria can be cleared from the tooth.
  • Next, your dentist will clean and seal the tooth to prevent future infection.
  • The tooth will then be filled with a special compound.
  • Finally, your dentist may do some restorative work if necessary to deal with the aesthetics of functionality of the tooth.

Frequently Asked Questions About Root Canals

Can a tooth still get reinfected after a root canal?

Yes, although it’s rare if the procedure and aftercareย are properly handled.ย Reinfection can occur if the tooth doesn’t seal properlyย ifย new decay reaches the filling, orย ifย a hidden canalย is missedย during the initial treatment.ย Dr. Perkins and Dr. Tow use advanced imaging and techniques to reduce these risks, but it’s still important to maintain excellent oral hygiene and attend regular check-ups.

Why do some people need a crown after a root canal?

A root canal removes the infected pulp inside your tooth,ย which can leaveย the structure weaker and more vulnerableย to fractures. In many cases,ย placingย a dental crown is recommended to restore strength, protect the tooth from breaking, and extend its lifespan.ย Think of the crown as a durable shield for your newly treated tooth, ensuring it lastsย many years.

Does having a root canal mean the tooth is now “dead”?

Technically, yes โ€” the tooth no longer has living pulp tissue inside. However, itย remains very functional. Dr. Perkins and Dr. Tow ensure that treated teethย stillย perform well for chewing and speaking. With proper care, your root canal-treated tooth can blend in seamlessly with the rest of your smile without any noticeable differences.

How can I tell if my tooth pain requires a root canal?

Not all toothachesย point to the need forย a root canal.ย Signs that suggest one are prolonged sensitivity to hot or cold, severe pain when chewing, darkening of the tooth, or swollen, tender gums nearby. However, symptoms can vary. Only a clinical exam andย diagnostic imaging by Dr. Perkins or Dr. Tow can confirm whether a root canal is necessary.

Are there alternatives to a root canal?

Sometimes, the only alternative is tooth extraction, followed by replacement options like implants, bridges, or partial dentures. Saving your natural tooth with a root canal is generally preferred because it helps preserve your bite alignment, jawboneย health, and overall oral function. Dr. Perkins and Dr. Tow will always discussย your optionsย before proceeding.

Why do some root canals take more than one appointment?

While many root canals canย be completedย in a single visit, certain factors โ€” such as the complexity of theย tooth’s root system, the severity of the infection, or the presence of swelling โ€” may require multiple visits. Additional time ensures the infectionย is fully cleared, andย theย toothย is properly sealedย and restored, giving you the best long-term results.

What happens if I delay getting a root canal?

Waiting too long can lead to worsening infection, increased pain, and the risk ofย the infectionย spreading to other areas, including the jawbone or bloodstream. Eventually, the tooth could become unsalvageable, requiring extraction. Timely root canal therapy with Dr. Perkins and Dr. Tow helps you avoid more extensive treatments and keeps your smile healthy and strong.
