How to Care for Your Baby's Teeth

When your baby flashes his gummy smile, caring for teeth that have yet to sprout is probably the last thing on your mind. "The surprising thing to a lot of parents is how early you need to start," says Amr Moursi, DDS, PhD, associate professor and chair of New York University's Department of Pediatric Dentistry.

At birth, your child's baby teeth -- 20 in total -- are already formed, hidden within the jawbone. Wiping your baby's gums once or twice a day with a soft cloth will "reduce the bacteria load and intensity [in a child's mouth] so when teeth erupt, there should be less cavity-causing bacteria," Moursi says. It's also a good way to get your baby used to having her mouth worked on.

Dental visits should start early, preferably within six months of the first tooth coming in, and no later than your child's first birthday.

Treating Teething

Brushing should start as soon as teeth appear, which can be as early as 4 months. Babies usually get bottom teeth first, then top ones. Don't get too worked up about when baby teeth come in. "The key things to look at are symmetry and pairings," Moursi says. Drooling, irritability, and putting objects into the mouth are sure signs of teething and tender gums.

Sometimes a low fever or loose stools happen, too. 

To relieve teething discomfort, remember two words: cold and hard. A frozen banana or a bagel can help reduce the pain.

Keep good early dental habits -- and your baby's gummy smile will soon turn into a happy, toothy grin.

Preventing Children's Cavities

Moursi offers these tips to start good habits for a lifetime of healthy teeth.

Don't share. A major source of cavities in children is a type of bacteria transferred between parent and child. Limit cup and utensil sharing, and never lick your baby's pacifier.

Brush up. Use a pea-sized amount of toothpaste twice a day (after breakfast and again before bedtime) on your baby's teeth. Skip the fluoride until age 2, when kids can usually be trusted not to swallow toothpaste.

Limit exposure. Frequent eating, even of healthy food, is more damaging to little teeth than sweets. For younger children, aim for eating about five times a day (three meals and two snacks).
