When a tooth is badly decayed, cracked or infected, you usually hear two options: clean it out and keep it, or take it out and be done with the pain. The root canal vs extraction question comes up in our clinic almost every day, and the honest short answer is this. If the tooth has enough sound structure left and the root is intact, saving it with a root canal is usually the better long-term choice. If the tooth has split, broken below the gum, or lost too much bone support, extraction is the wiser call.
Both are routine procedures and both end the pain. The difference lies in what happens afterwards: what you chew with, how your neighbouring teeth behave, and what you may need to spend over the next ten years.
This guide sets the two side by side so you walk into your consultation knowing the right questions to ask.
What is the real difference between a root canal and an extraction?
A root canal removes the infected pulp (the nerve inside the tooth), cleans the hollow canals in the root, and seals them. The outer shell of the tooth stays in place and is usually protected with a crown (a cap) afterwards. You keep your own tooth, your own root, and the bone around it.
An extraction removes the whole tooth, root and all. The socket heals over in a few weeks and the gum closes. The pain source is gone, but so is the tooth, and the bone that once held it starts to shrink because nothing is loading it any more.
Think of it like a house with a damaged foundation. A root canal repairs the inside while keeping the walls standing. An extraction demolishes the house. Both solve the immediate problem, but only one leaves you with a tooth to chew on, and that difference shapes everything that follows, from your diet to your dental bills.
The choice is rarely about which procedure is easier on the day. It is about what the tooth is worth to you over the next ten to twenty years, and what it will take to replace it if it goes. That is the lens our dentists use when they look at a damaged tooth on the X-ray, and it is the lens this article uses too.
When can a badly damaged tooth still be saved with a root canal?
A surprising number of teeth that look hopeless from the outside are good candidates for a root canal. The outer part can be heavily decayed or broken, but what matters is whether the root is sound and whether there is enough tooth above the gum to hold a crown.
A tooth is usually worth saving when:
- The root is intact on the X-ray, with no split running down its length.
- The gum around it is healthy, with little or no bone loss from gum disease.
- At least 1.5 to 2 mm of sound tooth remains above the gum all the way round, or can be exposed with a small gum procedure.
- The tooth is a molar or premolar you rely on for chewing, or a front tooth that matters for your smile.
- You are able to return for the crown within a few weeks of the root canal.
Success rates for well-done root canals are high. A systematic review of studies tracking root-treated teeth found that around 93 percent were still functioning four to five years later, and about 87 percent at eight to ten years (Ng, Mann and Gulabivala, 2010). Most root-treated teeth go on to last as long as their neighbours once they are crowned.
Many people in their thirties and forties come to us with a molar that broke while chewing sugarcane or hard jaggery sweets, or that was filled years ago and has now cracked. Those teeth often look dramatic, yet the root underneath is fine. Our dentists check with an RVG digital X-ray and, if the crack is hard to see, an in-house CBCT scan (a 3D X-ray). Results vary from person to person; our dentists assess this for you at the consultation.
When is extraction the wiser choice?
Some teeth cannot be saved, and pretending otherwise wastes money and time. Others could technically be saved but would not last, which is worse because you pay for a root canal and a crown and still lose the tooth a year later. In these cases removal is the honest recommendation.
Extraction is usually the right choice when:
- The tooth has a vertical crack that runs from the crown down into the root. These cracks cannot be sealed and bacteria keep entering.
- The tooth has broken well below the gum line, leaving nothing to hold a crown.
- Severe gum disease (periodontitis, also called pyorrhea) has taken away most of the bone around the root, so the tooth is already loose.
- A previous root canal has failed twice and the tooth still has an infection at the root tip.
- The tooth is a wisdom tooth, or a tooth that does not meet an opposing tooth and does nothing for chewing.
A loose tooth with deep bone loss is the clearest case. Cleaning the inside of the tooth does nothing about the missing bone outside it. The same is true for a split root. No amount of careful work seals a crack that flexes every time you bite.
If your dentist recommends removal, ask what happens to the space. A tooth extraction done with care preserves as much bone as possible, which keeps replacement options open later. The decision is not the end of the story, it is the start of the replacement plan.

Which hurts more, and which heals faster?
Here is a straight answer. Both procedures are done under local anaesthetic, so you feel pressure but not sharp pain during the work. The difference shows up in the days that follow.
After a root canal, the tooth can feel tender to bite on for two to five days, especially if it was badly infected beforehand. Ordinary painkillers usually manage this. There is no open wound, no stitches, and you can eat on the other side of the mouth the same evening. A Cochrane review found no meaningful difference in outcome between root canals done in one visit and those spread over two or more, so the number of appointments depends on the tooth, not on a rule (Manfredi et al., 2016).
After an extraction, you have a socket that needs to clot and close. Expect soreness and some swelling for three to seven days, a soft diet for the first few days, and a small set of rules about not rinsing hard or using a straw. A dry socket (alveolar osteitis), where the clot is lost, can make the second and third day quite painful and needs a return visit.
Neither option is dramatically harder to recover from, but the extraction has more aftercare and a slightly higher chance of a rough few days. The root canal has the extra step of the crown appointment later. If you are choosing purely on comfort, the two are closer than most people expect. Choose on what you want in your mouth afterwards instead.
Which costs more over the long run?
On the day, an extraction is cheaper than a root canal, and this is where many people stop thinking. The full picture includes what it takes to replace the tooth, because a gap in the back of the mouth is rarely a gap you can live with for long.
A root canal at our clinic falls in the range of ₹5,000 to ₹7,500, and the crown that protects it afterwards is priced separately depending on the material, from a metal crown at ₹3,000 to ₹5,000 to a zirconia crown at ₹9,500 to ₹35,000. That is the whole cost. The tooth is treated, protected and back in use.
An extraction costs less at the outset, but a missing back tooth usually needs an implant or a bridge within a year or two to stop neighbouring teeth from tilting into the space. An implant with its crown costs several times more than a root canal and crown, and a bridge means cutting down the two healthy teeth beside the gap. Saving the tooth is almost always the cheaper route over ten years.
A systematic review comparing outcomes of root-treated teeth and single implants found similar long-term survival for both, with the root-treated tooth needing far less intervention to get there (Torabinejad et al., 2007). Our root canal cost page explains what affects the figure for your tooth.
What happens to the gap if you choose extraction?
A gap does not stay still. Within weeks the bone that held the tooth begins to shrink because it is no longer being loaded when you chew. Within a year, the ridge can lose a large share of its width. One well-known study measured about a 50 percent loss of ridge width in the twelve months after extraction (Schropp et al., 2003).
Neighbouring teeth also move. The tooth behind the gap tilts forward, the tooth above or below it drifts down or up looking for something to bite against, and food starts to pack into the new spaces. Over a few years this changes your bite (occlusion) and can make cleaning harder, which invites decay and gum problems in teeth that were healthy before.
The options for filling the gap are a dental implant, a fixed bridge, or a removable partial denture. An implant is a titanium post placed in the bone with a crown on it, and it is the closest thing to the tooth you lost. Our page on dental implants for a missing tooth explains what is involved.
If you do choose extraction, decide on the replacement at the same time. Placing an implant within a few months, before the bone shrinks too much, is easier than placing one years later when a bone graft may be needed first. This is the single most useful thing to know before you agree to remove a tooth.
When should you see a dentist about a damaged tooth?
See a dentist as soon as you can once a tooth has broken, started to ache on biting, or begun to hurt at night. The longer a damaged tooth waits, the more the balance tips from saving it towards removing it. Decay keeps spreading, cracks keep growing, and infection at the root keeps taking bone.
The good news is that the decision is usually clear within a single visit. A consultation with an RVG X-ray tells the dentist whether the root is sound, and the treatment plan follows from that. If a root canal is the right path, it can often be started the same day, which ends the pain and stops the infection spreading further. Bring any old X-rays or reports you have, as they help show how the tooth has changed.

Frequently asked questions
Is it better to get a root canal or pull the tooth?
If the root is sound and enough tooth remains to hold a crown, a root canal is usually the better choice because you keep your own tooth and avoid the cost of replacing it. Extraction is better when the tooth has split, broken below the gum, or lost most of its bone support to gum disease.
Can a badly broken tooth still get a root canal?
Often yes. What matters is not how the tooth looks from outside but whether the root is intact and whether there is a collar of sound tooth above the gum for a crown to grip. Many teeth broken while chewing something hard have a healthy root and can be saved. An X-ray settles it.
Does extraction hurt less than a root canal?
Both are done under local anaesthetic, so neither hurts during the procedure. Afterwards, a root-treated tooth may feel tender to bite on for a few days. An extraction leaves a socket that is sore for three to seven days and needs a soft diet and a few aftercare rules. Recovery is closer than people expect.
What happens if I have a tooth pulled and do not replace it?
The bone around the socket shrinks, the tooth behind the gap tilts forward, and the opposing tooth drifts into the space. Over time this alters your bite, traps food, and makes neighbouring teeth harder to clean. Replacing a back tooth within a year or two avoids most of these problems.
Is a root canal cheaper than an implant?
Yes, by a wide margin. A root canal and crown together cost far less than removing the tooth and placing an implant with its own crown. Extraction alone is cheaper on the day, but once the replacement is added the saved tooth is nearly always the cheaper option over the years.
Can a tooth that already had a root canal be saved again?
Often it can. A re-treatment cleans and reseals the canals if the first treatment has failed, and works well when the cause is a missed canal or a leaking filling. If the root has cracked or the tooth has failed more than once, extraction and replacement may be the sounder route.
If you have a damaged tooth and want a clear answer on whether it can be saved, call +91 88705 04111 and book a same-day X-ray and consultation at Apollo Dental Vadavalli.
