How long does a root canal take?

30 doctors weighed in across 18 answers

Depends: Typically a front tooth takes less time then a back tooth. The more roots a tooth has, the more time it will take. Sometimes a tooth will have difficult roots to clean or find and that can add time. Typically a root canal will be 1-2 visits. An endodontist has a practice ltd to root canals so they have a lot of experience in dealing with different types of teeth.

RCT treatment: The time taken for rct treatment depends upon which tooth, the size, shape and location of the nerve canals, the health of the nerve and the particular dentist. I would estimate the time of each visit being approximately 1 hour (+/-) and one to three visits.

Depends: Depends on the tooth, depends on the patient, depends on the internal anatomy of the tooth, depends on the skill of the clinician, depends on the reason the root canal is being done. How long does it take to drive from town to town?

From 1 to 2.5 hours: Depends on the tooth's location, how many roots it has, if there is draining infection coming out of the tooth. It may possibly have to be done in two separate appointments.. Hope this helps!

Varies: Root canal treatment is a process of getting rid of an infection. Although the mechanical process may only take a visit or two the biologic process is indeterminable and dependent on several factors including the virulence of the bacteria and your defense systems to name two. Be patient, let the doctor determine how much time is appropriate for your case. Good luck.

1 hour: In the hands of an expert, the Endodontist, most treatment takes 1 hour or less. Non-specialist treatment typically takes longer. Of course, this is an average.

Depends which tooth,: what is the diagnosis and who is doing it. An upper molar or a lower molar root canal by a general dentist can take 2 or 3 hours, but by endodontist it's about 1.5 hours. A straight forward single root canal only takes about 45 min to 1 hour. In some cases multiple appointments are needed. Take care.

Depends: Partly dependent on the doc. An endodontist (root canal specialist) will do it quicker (maybe better) than a general dentist. 1-2 hours likely.

Specializes in Dentistry

Depends: Depending on the size and shape of the tooth, a root canal treatment can take, on average, about 1-1/2 hours. Time and care must be taken to properly instrument, clean, and disinfect the canals so that, when you seal them up, you leave nothing behind that could cause the treatment to fail in the future.

DEPENDS : An endodontist can do a root canal faster in most cases than a general dentist.Some teeth have one or more canals which would take longer. A tooth with 3 canals could take an hour or more or need two or 3 visits.A tooth with 1 canal could be done in 1 visit in about half to 45 minutes .If no complications most root canals can be done in one visit depending on the dentists skill or philosophy.

Specializes in Prosthodontics

Depends: During root canal treatment, the dentist needs enough time to open the tooth, enter the pulp chamber and root canals, clean the debris out of these areas, enlarge, sterilize and fill the root canals. This may take from 1-3 hours and from 1-3 visits (if there are no complications).

Depends : A one canal tooth would be shorter in time than a multi-rooted tooth-later more complex. An elective root canal takes less time and visits than a root canal done in crisis. So each situation varies. Ask your dentist.

1 hour: In the hands of the specialist - the Endodontist- most root canal treatments take 60 minutes or less. Of course there are exceptions based on the condition of the tooth and gum tissue and severity of decay and infection. Good Luck.

One to three visits: The majority of root canals are completed in a single visit. However, there are cases ( complex cases) that require multiple visits in order to disinfect the root canal space and complete the treatment.

Specializes in Endodontics

Depends: Is it a front or back tooth? Usually a front tooth is faster than a back tooth. Is it done by a specialist? Is it a straight root canal or retreatment? Is there any crown? What's your plan with the old crown? But to give you an estimate, you should give yourself at least an hour for a molar root canal.

Depends: Root canal treatment is the process used to eradicate an infection. The virulence of the bacteria as well as the complexity of the anatomy influence the speed of the process. Allow the doctor to use as much or as little time he or she feel the process should take. You will benefit in the end.
