Frequently Asked Questions about Dental Health

1. What are dental sealants, who should get them, and how long do they last?


Sealants are a thin, plastic coating that is painted on the chewing surfaces of teeth—usually the back teeth (the premolars, and molars)—to prevent tooth decay. The painted on liquid sealant quickly bonds into the depressions and groves of the teeth, forming a protective shield over the enamel of each tooth.

Typically, children should get sealants on their permanent molars and premolars as soon as these teeth come in. In this way, the dental sealants can protect the teeth through the cavity-prone years of ages 6 to 14. However, adults without decay or fillings in their molars can also benefit from sealants.

Sealants can protect the teeth from decay for many years, but they need to be checked for chipping or wear at regular dental check-ups.

2. What's the latest word on the safety of amalgam-type fillings?


The American Dental Association (ADA), the FDA, and numerous public health agencies say amalgams are safe, and any link between mercury-based fillings and disease is unfounded. Additionally, there is no solid, scientific evidence to back up the claim that if a person has amalgam fillings removed, he or she will be cured of any diseases.

In March of 2002, the FDA reconfirmed the safety of amalgams. Dental amalgams have been used for more than 100 years. The National Institutes of Health conducted several large-scale studies that concluded in 2006 that amalgam fillings were safe.

In addition, there has been concern over the release of a small amount of mercury vapor from these fillings, but according to the ADA, there is no scientific evidence that this small amount results in adverse health effects

3. How do whitening toothpastes work and how effective are they?

All toothpastes help remove surface stains through the action of mild abrasives. Some whitening toothpastes contain gentle polishing or chemical agents that provide additional stain removal. Whitening toothpastes can help remove surface stains only and do not contain bleach; over-the-counter and professional whitening products contain hydrogen peroxide (a bleaching substance) that helps remove stains on the tooth surface as well as stains deep in the tooth. None of the home use whitening toothpastes can come even close to producing the bleaching effect you get from your dentist's office through chair-side bleaching or power bleaching. Whitening toothpastes can lighten your tooth's color by about one shade. In contrast, light-activated whitening conducted in your dentist's office can make your teeth three to eight shades lighter.

4. I'm interested in changing the shape of my teeth. What options are available?


Several different options are available to change the shape of teeth, make teeth look longer, close spaces between teeth, or repair chipped or cracked teeth. Among the options are bonding, crowns, veneers, and recontouring.

Dental bonding is a procedure in which a tooth-colored resin material (a durable plastic material) is applied to the tooth surface and hardened with a special light, which ultimately “bonds” the material to the tooth.

Dental crowns are tooth-shaped “caps” that are placed over teeth. The crowns, when cemented into place, fully encase the entire visible portion of a tooth that lies at and above the gum line.

Veneers (also sometimes called porcelain veneers or dental porcelain laminates) are wafer-thin, custom-made shells of tooth-colored materials that are designed to cover the front surface of teeth. These shells are bonded to the front of the teeth.

Recontouring or reshaping of the teeth (also called odontoplasty, enameloplasty, stripping, or slenderizing) is a procedure in which small amounts of tooth enamel are removed to change a tooth's length, shape, or surface.

Each of these options differ with regard to cost, durability, “chair time” necessary to complete the procedure, stain resistant qualities, and best cosmetic approach to resolving a specific problem. Talk to your dentist to see if one is right for you.

5. I have a terrible fear of going to the dentist. What should I do?

If you fear going to the dentist, you are not alone. Between 9% and 15% of Americans state they avoid going to the dentist because of anxiety or fear. The first thing you should do is talk with your dentist. Some things that can help alleviate fear of dental visits are oral medication taken prior to the office visit to help you relax, nitrous oxide during the procedure, and the use of headphones with music.

6. There are so many toothpastes to choose from; how do I know which one to use?


First, when purchasing a toothpaste for you or your child, select one that contains fluoride. Fluoride-containing toothpastes have been shown to prevent cavities. However, one word of caution: use only a very small amount for children under age 6 (the size of their fingernail). This is because young children swallow toothpaste, and swallowing too much fluoride can lead to tooth discoloration in permanent teeth.

It is also wise to select a product approved by the American Dental Association. The ADA's Seal of Acceptance means that the product has met ADA criteria for safety and effectiveness and that packaging and advertising claims are scientifically supported. Some manufacturers choose not to seek the ADA's Seal of Acceptance. Although these products may be safe and effective, these products' performance have not been evaluated or endorsed by the ADA.

Next, when considering other properties of toothpaste—such as whitening toothpastes, tartar-control, gum care, desensitizing, etc.—the best advice for selecting among these products may be to simply ask your dental hygienist or dentist what the greatest concerns are for your mouth at this time. After consulting with your dentist or hygienist about your oral health's greatest needs, look for products within that category (for example, within the tartar control brands or within the desensitizing toothpaste brands) that have received the ADA Seal of Acceptance.

Finally, some degree of personal preference comes into play. Choose the toothpaste that tastes and feels best. Gel or paste, wintergreen or spearmint all work alike. If you find that certain ingredients are irritating to your teeth, cheeks, or lips; if your teeth have become more sensitive; or if your mouth is irritated after brushing; try changing toothpastes. If the problem continues, see your dentist.
