Dental Health FAQ

You should be brushing your teeth for two minutes, twice a day with fluoride toothpaste. Choose a soft-bristled brush that fits your mouth and place the toothbrush at a 45-degree angle to the gums. Gently move the brush back and forth in short, tooth-wide strokes. Brush the outer surfaces, the inner surfaces, and the chewing surfaces of the teeth. To clean the inside surfaces of the front teeth, tilt the brush vertically and make several up-and-down strokes. Brush your tongue to remove bacteria and keep your breath fresh.

It is safe to see a dentist when you are pregnant. Make sure to tell your dentist that you are pregnant and about any changes you have noticed in your oral health. In some cases, pregnancy can actually make some dental problems worse. Brushing and flossing contributes to your overall health, too, and if your mouth is healthy, it’s more likely that your baby’s mouth will be healthy.

Fluoride helps prevent cavities in children and adults by making teeth more resistant to the acid attacks that cause cavities. When you brush your teeth with fluoride toothpaste, use other fluoride dental products and drink water with fluoride you are preventing cavities and strengthening your teeth’s enamel.

Fluoride, also called nature’s cavity fighter, occurs naturally in varying amounts in water sources such as rivers, lakes and even the oceans. Fluoride was first added to public water systems in 1945 and its use has grown significantly over the past 70 years. The most recent data indicates 74.6% of the U.S. population served by public water systems receive the benefits of fluoridated water.

Studies have consistently shown that optimizing the level of fluoride in community water supplies is safe and effective in preventing dental decay in both children and adults by at least 25%. Simply by drinking water, people benefit from fluoride's cavity protection whether they are at home, work or school.

The American Dental Association recommends that children and adults use fluoride toothpaste displaying the ADA Seal of Acceptance. For children younger than 3 years, you should begin brushing your children’s teeth as soon as they start to appear in the mouth by using fluoride toothpaste in an amount no more than a smear or the size of a grain of rice. You should be brushing their teeth thoroughly twice a day (morning and night) or as directed by your dentist or physician. For children 3 to 6 years of age, dispense no more than a pea-sized amount of fluoride toothpaste and brush teeth thoroughly twice per day. Always supervise your child’s brushing to ensure that they use the appropriate amount of toothpaste and try and get your child to spit out most of the toothpaste.

Dental X-ray exams are safe; however, they do require very low levels of radiation exposure, which makes the risk of potentially harmful effects very small. Dental X-ray tools and techniques are designed to limit the body's exposure to radiation and every precaution is taken to ensure that radiation exposure is As Low As Reasonable Achievable (the ALARA principle). A leaded apron minimizes exposure to the abdomen and may be used when it will not interfere with acquisition of the dental radiograph. Also, a leaded thyroid collar can protect the thyroid from radiation, and should also be used whenever possible. The use of a leaded thyroid collar is recommended for women of childbearing age, pregnant women and children.

Dental amalgam is made from a combination of metals that include mercury, silver, tin, and copper. Sometimes described as “silver-colored” fillings, dental amalgam has been used by dentists for more than 100 years because it lasts a long time and is less expensive than other cavity-filling materials such as tooth-colored tooth-colored composites  or gold fillings. fillings.

Although dental amalgam is a safe, commonly used dental material, you may wonder about its mercury content. It’s important to know that when combined with the other metals, it forms a safe, stable material. Be assured that credible scientific studies affirm the safety of dental amalgam. Study after study shows amalgam is safe and effective for filling cavities. The American Dental Association, U.S. Centers for Disease Control and Prevention and World Health Organization all agree that based on extensive scientific evidence, dental amalgam is a safe and effective cavity-filling material. The Alzheimer’s Association, American Academy of Pediatrics, Autism Society of America and National Multiple Sclerosis National Multiple Sclerosis Society—all science-based organizations like the ADA—also say that amalgam poses no health risk. As with any dental work, you’ll always want to talk with your dentist about your individual situation in order to make the most well-informed choice.

The Mayo Clinic recently stated that dental amalgam is a safe and durable choice for dental fillings. They also note that "there are several kinds of mercury. The mercury [methylmercury] found in water that can build up in fish and lead to health problems if you ingest too much is not the same type of mercury used in amalgam."

The ADA supports continued research on all dental filling materials and would promptly inform the public if the scientific community and government regulatory bodies determined that any cavity filling material was unsafe for patients. Your dentist’s foremost priority is your health and safety. That’s why the ADA encourages you to talk with your dentist about your cavity treatment options and what’s right for you.
