Getting to the Root of Tooth Sensitivity

Chances are, you have experienced the discomfort of sensitive teeth.  Sensitivity in the  mouth can be a sign of other underlying issues.  Teeth feature three primary layers: the protective outer enamel, the sensitive dentin, and at the core, a canal that houses nerves and connective tissue. Enamel is the hardest tissue in the body and the second hardest naturally occurring substance on our planet. Dentin is a softer tissue that features tiny tubules, or channels, that allow sensations of pressure and temperature to be conducted to the tooth’s nerve. The nerves that lie within the inner canal then send signals to the brain.

Thin Enamel

Acid erosion and tooth wear can thin the protective enamel on the outside of teeth. Thin enamel provides less insulation, making teeth more sensitive to temperature fluctuations and pressure. Erosion is most often caused by acid in foods or from stomach acid. Enamel wear most often results from grinding and clenching teeth, a condition called bruxism.

Exposed Dentin

The crowns of teeth are covered with enamel, but the roots are not. If the gums recede, roots become exposed. The slightest pressure, such as that from wind, can cause intense pain to exposed teeth roots. Temperature fluctuations will also cause discomfort. Gums can recede for a number of reasons, including gum disease, grinding, or aging. (more…)

YEEEOWCH! Do You Suffer from Tooth Sensitivity?

Do you say no to sundaes? Do you wait for your soup to stop steaming? Is sugar painfully sweet? If your teeth ache with temperature fluctuations or sour and sweet tastes, you probably have sensitive teeth. The consequences of this touchy condition can range from a dull ache to sharp, shooting pains.

Teeth grinding, gum recession, gum disease, tooth decay at the gum line, cracks, chips, and plaque buildup can make teeth sensitive. Years of brushing too hard, consuming high-acid foods and drinks, “thin tooth enamel,” or using certain mouthwashes or toothpastes can also contribute to your sensitivity. If your sensitivity is a result of recent dental work, it may go away as quickly as it developed.

Is there hope that you’ll ever enjoy a brisk winter walk or a glass of refreshing iced tea without wincing when the cold hits your teeth?

YES!

As with most dental conditions, the first line of defense is good oral hygiene. Brush twice a day and floss at least once a day. Make your appointments with Dr. Pate for checkups and cleanings every six months (or as often as recommended). Switching to a soft-bristled toothbrush, using desensitizing toothpaste, and reducing the amount of acidic foods and drinks you ingest (colas, citrus, sports drinks, coffee, wine, etc.) are great first steps you can take at home.
