Tooth Sensitivity: Causes, Solutions and Treatment

The discomfort associated with tooth sensitivity may occur constantly or intermittently. Intermittent tooth sensitivity can occur while ingesting hot or cold food or beverages, or when cold air hits the teeth. In some cases, tooth sensitivity pain is mistaken for root damage.

What causes tooth sensitivity?

Aging accounts for some tooth sensitivity. As we age, enamel (the outer tooth surface) naturally wears down, exposing the dentin (the initial inner tooth surface) and causing sensitivity. Tooth sensitivity also results from a variety of other factors, including:

Gum recession.
Acidy liquids (such as soda) that cause enamel wear and dentin exposure.
Tooth grinding, in which case all teeth feel sensitive.
Brushing teeth too hard, which may cause enamel loss and dentin exposure.
Dental treatment such as teeth whitening, professional dental hygiene cleanings, orthodontics or tooth restorations (i.e., root canals).
Root nerve damage, gum disease (periodontitis), or a chipped or fractured tooth.

How does the dentist treat sensitivity?

Once it is determined that the cause does not require dental restorative treatment, our dentist may apply an in-office desensitizer, which acts as protective coating designed to thwart any hypersensitivity.

You have many options for the management of tooth sensitivity. For low-level sensitivity, a home maintenance program can be effective. Over-the-counter fluoride rinses, gels and toothpastes can make the root nerve less sensitive or build a protective coating to cover the sensitive tooth surface. For higher levels of sensitivity, an in-office desensitizer may provide relief for many months, even years.

Again, whether you ultimately choose an in-office desensitizer or over-the-counter toothpastes, rinses or gels, the most important step is to come and see us first to determine which tooth sensitivity solution is right for you.
