Is it possible to use medication to repair hurting roots that aren’t as damaged to warrant a root canal treatment?

Root canal treatment (RCT) is the cleaning of the innermost chamber of the tooth, the pulp. It is the pulp that provides the blood and nerve supply to the tooth and hence the source of pain. Once a cavity has touched the pulp of the tooth, or is very close to it, a root canal treatment is recommended.

The dentist removes the infected pulp and replaces it with a bio-compatible material. The pulp has to be removed from both the crown (the portion of the tooth that you see) and the canals of the root (the portion inside the bone). Hence the name, root canal treatment. Since this area is inside the bone, it is also the reason why the dentist requires some form of radio-graph  to determine the outline of the root and its canals.

At this level the cavity is very deep, since it has already infected the enamel, passed through the dentin layer of the tooth as well, and is now near the pulp. Once the cavity has reached dentin itself, a person will begin to have sensitivity and pain as it proceeds deeper towards the pulp. Any medication at this level, can only be placed by the dentist. What the dentist would do in such situations is, remove any infected dentin in the cavity, as much as possible, and apply the medication and then seal up the tooth with a temporary filling material. And then wait and watch, for a short period of about 3-4 weeks, approximately.

What do toothpastes like Sensodyne do that regular toothpastes do not?

Ever wonder what is the difference between regular toothpastes and those senso-toothpastes? What do they do and why are they more expensive? Are they meant for old people? or sick people?

The short answer – those toothpastes are meant for sensitive teeth.

Tooth sensitivity is experienced during the intake of cold or hot beverages. At times a sudden blast of air or chewing on something sweet can also trigger this sensitivity. This is caused by the movement of fluid within tiny tubules present in the layer of the tooth called dentin. Ideally these are protected from the changes inside the mouth by the outermost layer of the tooth called enamel. But when the enamel gets worn away, the inner layer (dentin) gets exposed. Enamel can get worn away due to improper brushing, demineralization by acidic foods, cavities and abnormal grinding forces on the teeth. Regurgitation from the stomach or constant vomiting, as seen in bulimia, can also result in wearing away of the enamel since the tooth comes in contact with the stomach acids. Sometimes, bleaching the teeth can trigger sensitivity.
