Tooth Decay - Prevention

(continued)

continued...

Gently work the floss between the teeth toward the gums. Curve the floss camera around each tooth into a U-shape, and gently slide it under the gum line. Move the floss firmly up and down several times to scrape off the plaque. Popping the floss in and out between the teeth without scraping will not remove much plaque and can hurt your gums.

You may want to try electric cleaning devices (interdental cleaning devices or interdental brushes) that are made to clean between your teeth. They can be as effective as using dental floss.

If your gums bleed when you floss, the bleeding should stop as your gums become healthier.

Healthy diet

  • Eat many types of food, especially whole grains, vegetables, and fruits, and food that is low in saturated fat and sodium. Good nutrition is vital for children as their teeth develop, and for adults to maintain healthy gums and avoid tooth decay.
  • Mozzarella and other cheeses, peanuts, yogurt, milk, and sugar-free chewing gum (especially gum that contains xylitol) are good for your teeth. They help clear your mouth of harmful sugars and protect against plaque. These make great after-meal snacks.
  • Avoid foods that contain a lot of sugar, especially sticky, sweet foods like taffy and raisins. The longer sugar stays in contact with your teeth, the more damage the sugar will do.
  • Avoid between-meal snacks.
  • Do not snack before bedtime, as food left on the teeth is more likely to cause cavities at night. Saliva production decreases while you sleep, so saliva does not clean your mouth well during sleeping hours.

Caring for your child's teeth

A child's dental care really starts with his or her mother's healthy pregnancy, because baby teeth begin to form before birth. If you are pregnant, eat a balanced, nutritious diet. And be sure to get enough vitamins and minerals. Pregnant women should have a complete dental exam and get treatment for any cavities or gum disease. For more information, see the topic Pregnancy.

By the time your child is 6 months of age, your doctor should assess the likelihood of your child having future dental problems.3 This may include a dental exam of the mother and her dental history, as the condition of her teeth can often predict her child's teeth. If the doctor thinks your child will have dental problems, be sure your child sees a dentist by his or her first birthday or 6 months after the first primary teeth appear, whichever comes first. After your first visit, schedule regular visits every 6 months or as your dentist recommends.

Experts recommend that your child's dental care start at 12 months of age.3

It's best to start good oral health habits before permanent teeth come in.

  • Parents and caregivers often share spoons, forks, and other utensils with babies. The saliva you may leave on the utensil contains bacteria that can cause tooth decay. Sometimes kissing can also transfer bacteria. You can help prevent early childhood tooth decay in your child by making sure that your family practices good dental health habits.
  • Do not put your infant or small child to bed with a bottle of milk, formula, juice, or any other product that contains sugar. The sugar and acids in these liquids can cause tooth decay (bottle mouth camera). Do not prop the bottle up in your baby's mouth, and remove the bottle as soon as your baby is done feeding or is asleep. Breast-feeding your infant to sleep is safe.
  • Discuss fluoride supplements with your dentist if your local water supply does not contain enough fluoride. To find out, call your local water company or health department. If you have your own well, have your water checked to find out whether your family needs fluoride supplements. You may also need to provide fluoride to your children if you use bottled water for cooking or drinking. Normal amounts of fluoride added to public water supplies and bottled water are safe for children and adults. If your child needs extra fluoride, your dentist may recommend supplements. Use these supplements only as directed. And keep them out of reach of your child. Too much fluoride can be toxic and can stain a child?s teeth.
  • If your child age 6 or older has cavities, ask the dentist if your child should try mouthwash. Be sure that your child does not swallow the mouthwash.
  • Keep your child away from cigarette smoke (secondhand smoke). Tobacco may lead to tooth decay and gum disease.1 As your child grows, teach him or her about the dangers of tobacco and secondhand smoke.
  • Consider having your dentist or dental hygienist put a sealant into the grooves of the chewing surfaces of your child's back teeth to help prevent cavities.

Only 18.5% of Americans never floss. You are missing out on a simple way to make a big difference in the health of your mouth. Regardless of how well you brush, plaque still forms between your teeth and along your gums. Floss removes food trapped between the teeth and removes the film of bacteria that forms there before it turns to plaque, which can cause inflamed gums (gingivitis), cavities, and tooth loss. Try flossing just one tooth to get started.

You are one of 31% of Americans who don't floss daily. You are missing out on a simple way to make a big difference in the health of your mouth.
