The tooth stays yours. Roughly 97 in 100 treated teeth are still in the mouth eight years on 1. Stricter counts that demand a fully healed root tip on x-ray still land in the high eighties to low nineties at a decade 2. That is unusually solid for a dental procedure.
The crown is not optional. A treated back tooth left without a crown fails about six times more often than one that got capped 3. The root canal and the crown are one package.
Against an implant it's a wash. Head-to-head, saving the tooth and replacing it with a single implant come out roughly even long-term, with the implant needing more touch-up work over the years 4.
The one thing to insist on: get the crown, and get it fast.
The arc is short then long.
- Days: the toothache ends and you sleep on that side again. About four in ten feel some soreness the first day, one in ten at a week, almost none beyond 5.
- Months: the bone around the root tip rebuilds itself.
- Years: the tooth is still there, and so is the ligament suspending it, so you still feel a poppy seed when you chew. An implant fused to bone can't do that.
The honest catch is cost. With the crown, budget roughly $2,000 to $3,500 per tooth in the US. Insurance usually pays a fraction and the annual cap eats the rest. The alternatives aren't cheaper: a single-tooth implant runs $4,000 to $6,000 and months of healing, and a bridge means grinding down two healthy neighbours permanently.
The fine print โ when to skip it, and what people get wrong
Root canals don't cause heart disease, cancer, or autoimmune illness; the "focal infection" idea was debunked long ago 6, 7. You also can't skip the procedure by riding out an abscess on antibiotics; they don't meaningfully cut the pain 8.
The avoidable failure is deferring the crown until the brittle tooth splits 3. The subtle one is a missed hidden canal in an upper molar, common enough to need a microscope 9.
Almost no medical condition is an absolute stop; local anesthesia handles it well. Tell the dentist about blood thinners and bisphosphonates before they start.

Root Canal Treatment
One or two visits of about an hour and a half, a sore jaw for a day or two, and you're done.
The toothache that brought you in ends within days, and the infection inside the tooth gets cleaned out for good.
One of the best-studied procedures in dentistry โ large reviews put long-term survival of treated teeth in the high-80s to mid-90s percent at a decade out.
Roughly $2,000โ$3,500 in the US once you include the cap that has to go on top. Insurance often covers part of it.
Clearing the infection inside the tooth removes a slow source of inflammation in your jaw โ modest, but a chronic abscess is not free.
Toothache lying down is one of the worst sleep wreckers there is. After treatment, the nights come back.
Chronic pain and the fear of losing a tooth wear you down. Both end the day the procedure works.
Keeping the natural tooth preserves jawbone and stops neighbouring teeth from drifting โ small but real effect on how the lower face holds up over decades.
A throbbing tooth quietly burns energy you didn't know you were spending. Clearing it gives back a small everyday lift.
Background pain hijacks attention without you noticing. Once the tooth stops hurting, your head clears.
