In this column, Ruhi Khanna, D.M.D., answers two questions from the readers regarding their dental needs.

Reader: Do you have sensitive teeth?

Khanna: If eating specific types of food - e.g. sweet, sour - or hot and cold
beverages, bothers you, and you find yourself avoiding these, there is a
good chance that you suffer from dentin hypersensitivity. You would not be
alone! About a fifth of all people have this problem, including youngsters
in their twenties and thirties.  This feeling can be persistent, or can come
and go, for quite some time. However, it is easily treated once your dentist
has identified the underlying cause.  Sometimes poor brushing technique can
aggravate the situation. Sometimes sensitivity is a side-effect of dental
cavities or broken or cracked teeth.  Your dentist might recommend that you
use special desensitizing toothpaste such as Sensodyne or Tom's of Maine
Natural Toothpaste, or might recommend in-office treatments.


Reader: What are sealants and how can your kids benefit from them?

Khanna: Are you surprised, or dismayed, by the early age at which your children, or their friends, might be developing cavities? While good diet and good dental habits are the primary prevention methods, your dentist can provide
additional safeguards.  Brushing and flossing often aren't good enough. Molars - those that emerge around six-years and around twelve-years - are especially susceptible. Sealants are resins that can protect the deep grooves in such molars.  They are painted on the enamel. No additional drilling is needed. They last a long time and can be easily replaced. In fact, even an adult with no cavities can benefit by using sealants.
