Tooth Sensitivity and Exposed Roots: Understanding the Link

Patients who come to our Albuquerque dental care center know that we pay close attention to all sorts of dental health issues. Whether the teeth or the gums are affected, our team can address these problems using the latest in general, cosmetic, and restorative dentistry treatments.

In many cases, tooth sensitivity is the first sign of a problem. This is often due to the exposure of the tooth roots. Let’s take a moment to discuss these issues. To understand why tooth sensitivity occurs when tooth roots are exposed, it’s important to first consider the anatomy of a tooth.

The Anatomy of a Tooth

There are three basic layers to a tooth’s structure:

  • Enamel – This is the topmost layer of the tooth. Enamel is one of the strongest substances in the human body.
  • Dentin – This is the underlying structure of a tooth beneath the enamel. Dentin is porous, and the pores in the dentin are known as dentinal tubules.
  • Pulp Chamber – Each tooth has a hollow central chamber that is filled with a substance known as dental pulp. This dental pulp is comprised of nerves, blood vessels, and connective tissue.

In addition to this, it’s important to consider the position of the teeth relative to the gumline. Above the gumline, the portion of the tooth is known as the crown. Beneath the gumline, the tooth root extends down into the jawbone.

Why Tooth Sensitivity Occurs When Roots Are Exposed

When the gumline recedes and exposes more of the tooth’s root structure, it reveals a part of the tooth that is intended to be covered up. The tooth roots have less enamel on them than the crowns of the teeth. This means closer access to the dentin. Since dentin is porous, it is much more sensitive than enamel, particularly with regard to hot and cold temperatures.

Causes of Gum Recession

Some of the most common causes of gum recession include:

  • Use of tobacco products
  • Gum disease
  • Aggressive brushing and flossing
  • Teeth grinding (bruxism)
  • Crooked teeth
  • Certain medical conditions

The Dangers of Exposed Tooth Roots

When tooth roots are exposed, this can lead to serious issues with tooth sensitivity and even dental pain. The roots of the teeth are generally more susceptible to tooth decay. If decay occurs below the gumline in the exposed root structure, this can be very difficult to treat, and means an increased risk of root canal infection and potential tooth loss.

Treatments for Gum Recession

When gum recession occurs, the best option for treatment is usually soft tissue augmentation. This procedure involves the use of gum grafts to rebuild the gumline. These grafts will help restore the missing gum tissue, protecting the underlying tooth roots in the process.

Before soft tissue, augmentation, it’s important for any issues affected the tooth roots to be treated first. These treatments can be discussed during the treatment process.

Tips for Preventing Gum Recession

To prevent gum recession, consider the following tips:

  • Brush your teeth at least twice a day
  • Floss at least once a night
  • Be gentle when brushing and flossing
  • Avoid the use of tobacco products
  • Stay hydrated by drinking water throughout the day
  • Visit your dentist twice a year for regular checkups
