Root Canals Revisited… tooth is going to need a root canal…” It seems that one of the worst phrases that we dentists can utter is, “Well, ma’am, it seems that certainly is never my intention. To be honest, I believe that root canals generally have a worse reputation than they deserve. A few years back, I remember reading a scientific study about the public’s perception of dentists. I don’t remember the details, but the main point was that we dentists aren’t generally bad people; we’re just played that way on film. Why money was spent to study this dilemma is a whole other question. Rarely can I finish my explanation before I see the white knuckles and dental fear set in.

In other words, a cavity, crack, or some other trauma has injured the nerve of the tooth beyond repair. Generally, the pain of that toothache comes from your body’s actual response to the trauma…swelling. Swelling inside of an enclosed space, like a tooth, tends to do more damage than good and, as an added bonus, tends to be darn painful. So why do teeth need root canal therapy?

After becoming completely numb, a prerequisite to any comfortable dental procedure, your dentist will use a combination of mechanical debridement and antibiotic solutions to clean out your tooth. After this cleaning and shaping of the nerve chamber (some teeth can have up to four or five different nerve canals), the tooth root is sealed up to prevent bacteria from getting back in. So what does a root canal do? A root canal simply removes all of the nerve tissue, blood vessels, done with something as simple as a tooth colored filling where the nerve was removed. Back teeth almost always have to have a cap or crown to seal them off because they become brittle once their nerves and blood vessels have been cleaned out. Either way, your tooth can usually be pain free and looking as good as ever, sometimes in a single visit. Hopefully, it wasn’t as bad as you might have heard on TV. The final step is to restore your tooth to its former glory. On front teeth, this can sometimes be Until next time, keep smiling. ‐Questions or comments can be sent to Drs.
