“We all scream for ice cream,” the saying goes. But what if eating ice cream — or any very cold or hot food — literally makes you want to scream because your teeth hurt so much?

What causes sensitivity in teeth?

Understanding the anatomy of a tooth helps explain what happens when a tooth becomes sensitive to heat and cold. A tooth is composed of three types of tissue: a hard outer shell of enamel, the body of the tooth composed of the dentin, and an interior tissue of the pulp.

Enamel: The enamel forms the outside of the crown, the part of the tooth you normally see. Made of densely packed crystals of calcium, it is resistant to wear. It is not living tissue, and does not contain nerves, but it is capable of transmitting temperature like hot and cold.

Dentin: Inside the tooth's crown and root is a living tissue called dentin, which is a porous structure similar to bone. It is composed of microscopic tubules containing living cells, which are encased in a hard substance made of calcium crystals.

Pulp: The living dentin transmits sensation through to the pulp, which is in the center of the tooth and contains the tooth's blood vessels and nerves.

A tooth's enamel normally protects the dentin from exposure to extremes of temperature and pressure. If you wear away the enamel and expose the dentin, it will pass sensation through to the nerves in the pulp more directly. The result can range from a twinge to an excruciating pain.

Sensitivity can be caused by:

  • Overzealous tooth brushing resulting in enamel wear and consequently dentin exposure and wear.
  • Enamel and dentin erosion by acids in the foods and beverages you eat and drink.
  • Tooth decay — the most common cause of sensitivity. Decay destroys enamel and dentin inflaming and infecting the living tissues of the pulp, which become increasingly painful.

What can you do to make your teeth less sensitive?

  • Use a soft bristle tooth brush, and brush the affected teeth gently to remove all bacterial plaque. We can advise you on safe and effective brushing techniques.
  • Use toothpaste that contains fluoride. Fluoride strengthens tooth surfaces and makes them more resistant to sensitivity and decay.
  • Ask us about professionally applied fluoride varnishes or filling materials that can cover and replace sensitive or lost tooth structure.

Of course, if the problem is caused by tooth decay, make an appointment with us to remove the decay and place a filling in the sensitive teeth.

TreatingPainfulToothSensitivityBeginsWithFindingitsSource

If you wince while eating certain foods and beverages, you're not alone — one in three Americans suffer from the pain of tooth sensitivity. Fortunately, there are ways to treat it and reduce the pain.

Dentinal hypersensitivity occurs when dentin loses its protective cover. Dentin, a living tissue within a tooth, is composed of tiny tubules that act as conduits for transmitting sensations from the surface of the tooth to the nerves in the inner pulp. These tubules are protected by cementum, a hard, outer layer that covers the tooth root. But when the root becomes exposed, the cementum is easily stripped from the root. The tubules become more sensitive to sensations of temperature or pressure.

Receding gums are the main culprit for root exposure. This condition can result from periodontal disease, which arises mainly from poor oral hygiene. At the other end of the spectrum, over-aggressive brushing can lead to receding gums. Brushing may also contribute to another source of dentinal hypersensitivity: enamel erosion. The minerals in enamel begin to soften and erode as the acidic level of the mouth rises. Saliva neutralizes the acid and can restore a neutral balance in about thirty minutes to an hour after eating. If you brush before this process completes, you could brush away some of the softened enamel.

To properly treat tooth sensitivity, our first step is to find the cause. If it stems from improper or premature brushing, we can counsel you on proper technique. If periodontal disease is a factor, we would first treat the disease and then work with you on a proper oral hygiene regimen to reduce bacterial plaque, the main cause of the infection.

There are treatments as well to reduce nerve sensitivity and thereby ease the pain. Toothpastes and other mouth products with fluoride help reduce sensitivity, as well as products containing potassium nitrate or potassium citrate. We can also apply a varnish containing a concentrated dose of fluoride directly to tooth surfaces. Another approach is to block the tubules using bonding agents or sealants; this will reduce their capacity to receive and transmit sensations.

If you would like more information on the causes and treatment of tooth sensitivity, please contact us or schedule an appointment for a consultation. You can also learn more about this topic by reading the Dear Doctor magazine article “Treatment of Tooth Sensitivity.”

ToothSensitivityFAQs

It can start with a simple twinge or be as severe as excruciating pain. From time to time, we have patients asking questions about tooth sensitivity — what causes it? What can be done about it? For these reasons, we have put together the following list of frequently asked questions (FAQs) so that you can develop a healthy understanding about this painful and often avoidable condition.

What is tooth sensitivity?

The first layer of protection of the teeth is enamel. Enamel is a dense crystalline structure, the hardest substance produced by animals. It is an inert substance that has no nerve supply and thus it protects the teeth from temperature and pressure changes. When it is compromised, worn thin, or exposed due to gum recession, it leaves the dentin exposed and vulnerable. Unlike enamel, dentin is living and has delicate nerve fibers within it.

What triggers tooth sensitivity?

Once dentin is exposed, it can become sensitive. It typically occurs when the dentin comes in contact with heat, cold, or the “double whammy” combination of both cold and sweets. Even the bristles of a soft toothbrush can irritate exposed dentin causing sensitivity and pain.

What can be done to minimize tooth sensitivity?

One of the simplest ways to minimize or prevent sensitivity is by teaching proper brushing techniques so that teeth are cleaned without causing either sensitivity or damage. Brushing too hard is a frequent culprit. Being overzealous can literally cause gum recession, leave dentin, and wear it away leaving it grooved. Another step to minimize sensitivity is to use a toothpaste containing fluoride. Fluoride increases the strength of tooth surfaces and thus makes teeth more resistant to attack by acids and sweets. If severe, we may need to apply a barrier to cover the sensitive areas. These barriers may range from concentrated fluoride varnishes to replacing lost tooth structure with filling materials.
