How many root canals do the different types of teeth have?
Some of the videos here on Dental-Picture-Show.com (including: What are the purpose and goals of root canal treatment?, Root Canal Therapy- The procedure.) make mention of the fact that some factors associated with the process of having root canal treatment hinge on the number of individual canals that the tooth has. Some of these include treatment cost, procedure time and case complexity. (Look below for links to more information about these topics.)
If you do happen to know which tooth it is that you are having treated, the table on this page can give you an idea of how many canals it probably has.
Table: Total number of roots and root canals different types of teeth can, in most cases, be expected to have.
The number of canals depends on which tooth (and even which tooth root) you are talking about.
Teeth always have at least one root, and each tooth root always has at least one root canal. But beyond that basic format, a lot of variability exists.
Different types of teeth characteristically have an expected number of roots, usually ranging between one and three. And, just as characteristically, some tooth roots are well know for having (or else a strong possibility for having) two or more root canals.
Taking all of these statistics into consideration, it's easy enough to anticipate how many root canals your dentist will find inside your tooth.
The number of root canals a tooth has generally correlates with the case's complexity.
You can expect, for the most part, that the more root canals a tooth has, the greater the degree of difficulty associated with treating it.
That's not to say that teeth with two canals are twice as difficult to treat as those that have just one. But a dentist can generally anticipate that the canals they find in the former will likely be narrower, probably harder to locate, and potentially more challenging to treat. Without question, a dentist is likely to experience far fewer frustrations when treating an upper incisor (a tooth known for typically having a large single canal) as opposed to an upper molar (which may easily have 4, or even 5, canals).
As you'd expect, procedure cost and appointment times vary according to treatment complexity.
You'll find that the cost for root canal treatment, as well as the amount of time and number of visits it takes to complete it, correlates with the complexity of the treatment (number of canals involved).
Treatment costs.
If you'll explore this link (root canal treatment cost estimates), you'll find, for example, that treating a molar (a tooth that typically has at least 3 canals) can be expected to cost roughly 30 to 40% more than an incisor (a tooth that has just a single canal).
Treatment / appointment time.
In corresponding fashion, appointments scheduled for treating a molar might be expected to run over an hour (and possibly more than one appointment may be needed). In comparison, teeth having a single canal can often be treated in a single appointment that lasts less than an hour.
