Toothpaste for Sensitive Teeth Can Help Relieve Pain

Donna Pleis

Remember singing "I scream! You scream! We all scream for ice cream!" as a kid? Ice cream may still have you screaming as an adult if you're one of the many people with sensitive teeth. Ice cream, iced tea and hot coffee are just a few of the hot and cold foods and drinks that cause a painful reaction. If you're one of these people, know that you're not alone: Dentists say that tooth sensitivity is one of the most common complaints from patients. The good news is that, in many cases, toothpaste for sensitive teeth can take care of the problem.

What Is Dentin Hypersensitivity?

A strong layer of enamel covers the visible portion of your teeth, while the roots are protected by cementum, a layer that is not quite as hard as enamel. Both enamel and cementum protect the inner, softer layer of your tooth, which is made up of a material called dentin. The American Dental Association describes dentin as being made up of microscopic tubules that are full of nerve endings. Whenever a tooth's enamel or cementum does not fully cover the dentin, hot or cold liquids and foods and even cold air can cause nerve irritation (dentin hypersensitivity) that causes a short, sharp pain.

Causes of Sensitive Teeth

There are many reasons why your teeth may be sensitive. It's not unusual for a cracked tooth, a worn, leaky filling or tooth decay to be the source of sensitivity and pain. Highly acidic foods and drinks can cause erosion of your tooth enamel, or enamel may be worn away due to abrasion from aggressive brushing or grinding of teeth. Receding gums are often the culprit. Whether due to gum disease or brushing with a hard toothbrush, exposed roots and cementum can cause temperature sensitivity. According to the Academy of General Dentistry, if you have sensitivity to hot and cold temperatures for more than three or four days, you should see your dentist for an evaluation of the problem.

Occasionally, you may notice tooth sensitivity after dental treatments such as fillings, crown preparations, bleaching and even professional cleanings. This is usually temporary, but let your dentist know if it continues. You may also find that your teeth become sensitive when using a tartar control or whitening toothpaste. If you think this is the case, talk to your dentist or dental hygienist about the best toothpaste to use.

Toothpaste for Sensitive Teeth

Your dentist will want to diagnose and treat the underlying cause of your sensitivity. If the dentist does not see an obvious reason for your pain, then the situation may call for treatment of the sensitive area with topical fluoride and use of a desensitizing toothpaste for a period. These toothpastes contain ingredients that block off the nerve-enriched tubules in the exposed dentin. This protects the dentin and keeps you from feeling pain when eating and drinking. These toothpastes should be used on a regular basis for at least one month to get the maximum benefit. Your dentist may also advise you to massage some of the paste onto the sensitive areas after brushing.

Colgate has formulated desensitizing toothpastes that can give you long-lasting results. Both the Original and Gentle Whitening formulas of the Colgate® Sensitive Pro-Relief desensitizing toothpaste line contain fluoride for cavity protection, while the new Enamel Repair version has the highest level of fluoride found in nonprescription toothpastes. This level of fluoride can help reinforce weak areas in your enamel. Your dentist may use the Colgate® Sensitive Pro-Relief Desensitizing Paste as an in-office treatment to give you immediate relief that lasts up to four weeks. Colgate also offers a soft-bristle toothbrush specifically designed for sensitive teeth.

If ice cream hasn't been on your menu because of tooth sensitivity, don't wait. Get to your dentist, and let dental professionals determine the source of the problem. Desensitizing toothpaste might do the trick and allow you to head back to the ice cream parlor.
