A tooth starts hurting. Maybe it woke you up, or maybe it has been a dull ache for weeks that you kept meaning to deal with. Either way, you have probably already looked it up and landed on the same three things everybody lands on: filling, root canal, or pull it.
Here is the honest answer to which one you need: it depends on how much healthy tooth is left, and on whether the damage has reached the nerve inside. That is not a dodge. It is genuinely the whole decision, and a dentist can usually tell you within a few minutes of looking at an X-ray.
What each one actually does
A filling repairs the tooth. The decay is cleaned out and the space is rebuilt, usually in one visit. This is the answer while the decay is still confined to the outer layers of the tooth and has not reached the nerve, which is more often than people expect.
A root canal treatment saves the tooth. The infected or damaged tissue inside the tooth is cleaned out, the space is sealed, and the outside of the tooth stays right where it is. Most root canals are followed by a crown, because a tooth that needed one is usually a tooth that has lost some structure and needs the reinforcement.
A tooth extraction removes the tooth. That solves the pain and the infection permanently, but it leaves a gap, and gaps have consequences of their own that need planning for.
All three are routine. None of them is a failure on your part.
Is it a cavity or something more serious?
Decay causes pain long before it reaches the nerve. A tooth that twinges with something sweet or cold and settles within a few seconds, with no swelling and no ache at night, is often a cavity that can simply be filled. Once decay reaches the pulp, a filling can no longer fix it, and an X-ray settles that quickly. Regular checkups and cleanings are how most cavities get caught while a filling is still the answer. The rest of this post is about your options once a filling has been ruled out.
How the decision gets made
Five Factors
How much tooth is left above the gum. A tooth needs enough solid structure for a crown to grip. When decay has eaten down close to the gumline, there may not be enough left to build on, no matter how well the root canal goes.
Whether the tooth is cracked, and where. A crack in the enamel is often fixable. A crack that runs vertically down into the root usually is not, because there is no way to seal it. This one is frustrating, because a badly cracked tooth can look fine from the outside.
Whether the infection has reached the bone. Infection that has spread beyond the root into the surrounding bone changes the calculation, and sometimes changes the timeline too.
Where the tooth sits. A molar doing heavy chewing work is worth more effort to save than a wisdom tooth that was never pulling its weight. Wisdom teeth are usually removed rather than treated, because they are hard to clean and easy to reinfect.
Your gum health overall. A tooth held in place by bone that has already receded may not have a long future even after a perfect root canal.
Saving the tooth is usually the first choice
There is a good reason dentists lean toward keeping a natural tooth when keeping it is realistic. Your own tooth has a root in the bone, and that root keeps the bone stimulated. Remove it, and the bone underneath slowly begins to shrink. Neighboring teeth start to drift toward the space. The bite shifts. None of that happens overnight, but it does happen, and every fix for it costs more than the root canal would have.
So when a tooth is restorable, restoring it is generally the better long game, even though it takes an extra visit.
When pulling it is the better call
Sometimes it clearly is. When the tooth is fractured through the root, when there is not enough structure to hold a crown, when infection is significant, or when the tooth is a wisdom tooth causing trouble, an extraction is the treatment that actually solves the problem instead of postponing it.
The important part is what comes next. If the tooth was anywhere visible or load-bearing, plan the replacement at the same time you plan the removal. Dental implants replace the root as well as the tooth and keep the bone working. Dentures and partials are a good fit in other situations. Deciding early is easier than deciding a year later.
The one thing that makes it worse
Waiting.
Almost every tooth that ends up needing extraction spent a stretch of time being a tooth that could have had a root canal. Pain that comes and goes is not a sign the problem is resolving — it often means the nerve inside is dying, which is why the ache eventually fades. The infection keeps going.
If a tooth hurts, if it is sensitive to heat or cold, if the gum around it is swollen, or if there is a bad taste that will not go away, get it looked at while the simpler options are still on the table.
Common questions
Is a root canal or an extraction more painful?
Neither should hurt during the appointment, since both are done with the area fully numbed. Recovery differs a little: a root canal usually leaves the tooth tender for a few days, while an extraction leaves a socket that needs about a week of care and takes a few weeks to fully close over.
Is it cheaper to just pull the tooth?
On the day, yes. Over time, usually not. An extraction leaves a gap, and replacing that gap with an implant or a partial costs more than a root canal and crown would have. Pulling a tooth is the cheaper option only when you have decided not to replace it, which is reasonable for some back teeth but rarely a good idea anywhere visible.
How long does a root-canal-treated tooth last?
Often for decades. A tooth that has had a root canal and been properly crowned can last the rest of your life with normal brushing, flossing, and regular checkups. It is not a temporary fix.
Can I choose an extraction even if the tooth could be saved?
You can. It is your tooth and your decision. We will tell you what we would recommend and why, including what replacing it would involve, and then we will do what you decide.
How do I know if it is just a cavity that needs a filling?
You often cannot tell from symptoms alone, but there are hints. A cavity that has not reached the nerve usually causes short sensitivity to sweet, hot, or cold that fades within seconds, without swelling and without pain that wakes you up. Pain that lingers for minutes, throbs at night, or comes with a swollen gum suggests the nerve is involved. An X-ray answers it definitively, which is why coming in early often means a filling instead of a root canal.
What if I wait and see whether the pain goes away?
Pain fading is not always a good sign. When the nerve inside a tooth dies, the ache often stops while the infection continues spreading into the bone. That is frequently how a tooth that was once savable stops being savable, so it is worth getting looked at even if the pain has eased.
