Root canal or extraction? How to choose when a tooth is badly damaged

The honest answer: save the tooth when you can

If your dentist says the tooth can be saved, a root canal is usually the better first choice. Dental groups, including the American Association of Endodontists (AAE), recommend keeping your natural tooth whenever it is possible to do so.

But some teeth cannot be saved. A tooth that is cracked below the gum line, has too little healthy structure left or sits in a weak jaw may be better pulled. The right answer depends on your tooth, your health and your goals. Only an exam and an X-ray can tell.

Many people arrive at this choice in pain and in a hurry. Take a breath. A good dentist will not rush you into one answer. You should leave the visit knowing what is wrong, what your choices are and what each one involves.

Why keeping your own tooth matters

Your natural tooth does jobs that no replacement does perfectly. It is anchored in the bone, it senses pressure when you bite, and it holds its neighbors in place.

When a tooth is pulled and not replaced, the teeth next to it can slowly lean into the gap. The tooth above or below can drift too. The bone in that spot can also shrink over time, because it no longer gets the pressure of chewing.

The AAE points out that a root canal avoids those problems and can spare you the cost of replacing the tooth with a bridge or implant. The tooth stays where it is, and you keep chewing with it.

There is also a comfort factor. A root canal tooth feels like your own tooth, because it is. You brush it and floss it the same way, and you do not have to learn to live with a new part in your mouth.

Replacing a tooth is not a small step. A bridge needs the teeth on each side to be shaped down. An implant needs enough healthy bone and healing time. These are good options, and we offer them, but they are not the same as the tooth you were born with.

When a root canal makes sense

A root canal is a good fit when the damage is inside the tooth, and enough solid tooth is left to rebuild. For example:

• Deep decay has reached the nerve, but the outer structure is still strong
• A tooth has a deep chip or crack that does not run down into the root
• The nerve is infected or dead, and the bone around the root can still heal
• You want to keep the tooth and can commit to the crown that follows

When extraction is the better choice

Pulling a tooth is the right call in some cases. Your dentist may suggest it when:

• The tooth has a crack that splits the root, which usually cannot be repaired
• So much of the tooth is gone that a crown would have nothing solid to hold on to
• Gum disease has loosened the tooth and the bone around it is badly damaged
• The tooth is badly impacted or crowded, as with some wisdom teeth
• A root canal was tried before and the tooth cannot be treated again

What each path looks like, and why not to wait

With a root canal, your dentist removes the damaged nerve, cleans the inside of the tooth and seals it. Cleveland Clinic says most root canals take about 60 to 90 minutes. A crown usually follows to protect the tooth. Mayo Clinic notes that a back tooth usually needs one.

With an extraction, your dentist numbs the area and removes the tooth. A simple extraction takes less time in the chair. Cleveland Clinic says most people return to routine activities within 48 to 72 hours, though bone healing takes longer, up to four months for a large tooth like a molar.

After an extraction, you will need to think about the empty space. That is where options like an implant, a bridge or a partial denture come in. These are separate treatments with their own steps and costs.

Waiting rarely makes this choice easier. An infected tooth can spread to the gum, the jaw and, in rare cases, farther into the face and neck. See a dentist soon if you have swelling, a fever, a pimple on your gum or pain that keeps coming back.

If swelling spreads toward your eye or neck, or you have trouble swallowing or breathing, go to an emergency room right away.

The cost question, without the guessing

People often ask which is cheaper. In the short term, an extraction usually costs less than a root canal plus a crown. Over the long term it can cost more, if you then replace the tooth with an implant or bridge.

We cannot quote a number in an article, because it depends on the tooth, the plan and what your insurance covers. What we can say is this: ask for the total of each path, not only the first step. A fair comparison includes the crown after the root canal, or the replacement after the extraction.

Most dental insurance plans cover part of both a root canal and an extraction. Your plan sets the exact amount, so check yours or ask our office to help.

One more thing to weigh is time. A root canal and a crown can take two or three visits. An extraction can take one, but a replacement can add more visits and months of healing. Ask for the full timeline for each path so nothing surprises you.

It also helps to think about the tooth you are trying to keep. A front tooth that shows when you smile may be worth saving at nearly any cost. A back tooth that is badly broken may not be. Your dentist can help you weigh the value of each tooth in your own mouth.

Questions to ask your dentist

A good decision starts with good questions. Try these:

• Can this tooth be saved, and how sure are you?
• How much healthy tooth is left to support a crown?
• What is the plan if the root canal does not work?
• If we pull it, how will we replace it, and when?
• What is the total cost and timeline for each choice?
• What happens if I wait?
