If you wince with pain after sipping a hot cup of coffee or chewing a piece of ice, chances are that you suffer from "dentin hypersensitivity," or more commonly, sensitive teeth.

Hot and cold temperature changes cause your teeth to expand and contract. Over time, your teeth can develop microscopic cracks that allow these sensations to seep through to the nerves. Exposed areas of the tooth can cause pain and even affect or change your eating, drinking and breathing habits.

At least 45 million adults in the United States suffer at some time from sensitive teeth.

Sensitive teeth result when the underlying layer of your teeth (the dentin) becomes exposed. This can happen on the chewing surface of the tooth as well as at the gum line. In some cases, sensitive teeth are the result of gum disease, years of unconsciously clenching or grinding your teeth, or improper or too vigorous brushing (if the bristles of your toothbrush are pointing in multiple directions, you're brushing too hard).

Abrasive toothpastes are sometimes the culprit of sensitive teeth. Ingredients found in some whitening toothpastes that lighten and/or remove certain stains from enamel, and sodium pyrophosphate, the key ingredient in tartar-control toothpastes, may increase tooth sensitivity.

In some cases, desensitizing toothpaste, sealants, desensitizing ionization and filling materials including fluoride, and decreasing the intake of acid-containing foods can alleviate some of the pain associated with sensitive teeth.

Sometimes, a sensitive tooth may be confused by a patient for a cavity or abscess that is not yet visible.

In any case, contact your dentist if you notice any change in your teeth's sensitivity to temperature.

What Is Tooth Decay?

Tooth decay is caused by a variety of things; in medical terms, cavities are called caries, which are caused by long-term destructive forces acting on tooth structures such as enamel and the tooth's inner dentin material.

These destructive forces include frequent exposure to foods rich in sugar and carbohydrates. Soda, candy, ice cream—even milk—are common culprits.  Left inside your mouth from non-brushing and flossing, these materials break down quickly, allowing bacteria to do their dirty work in the form of a harmful, colorless sticky substance called plaque.

The plaque works in concert with leftover food particles in your mouth to form harmful acids that destroy enamel and other tooth structures.

If cavities aren't treated early enough, they can lead to more serious problems requiring treatments such as root canal therapy.

Preventing Cavities

The best defense against cavities is good oral hygiene, including brushing with a fluoride toothpaste, flossing and rinsing. Your body's own saliva is also an excellent cavity fighter, because it contains special chemicals that rinse away many harmful materials. Chewing a good sugarless gum will stimulate saliva production between brushing.

Special sealants and varnishes can also be applied to stave off cavities from forming.

If you have any of the following symptoms, you may have a cavity:

• Unusual sensitivity to hot and cold water or foods.
• A localized pain in your tooth or near the gum line.
• Teeth that change color.

Baby Bottle Tooth Decay

Baby bottle tooth decay is caused by sugary substances in breast milk and some juices, which combine with saliva to form pools inside the baby's mouth.

If left untreated, this can lead to premature decay of your baby's future primary teeth, which can later hamper the proper formation of permanent teeth.

One of the best ways to avoid baby bottle tooth decay is to not allow your baby to nurse on a bottle while going to sleep. Encouraging your toddler to drink from a cup as early as possible will also help stave off the problems associated with baby bottle tooth decay.
