The sooner the better. Starting at birth, clean your baby’s gums with a clean, damp washcloth. As soon as teeth erupt, begin cleaning them — teeth can begin to decay as soon as they come in.
Again, use a moistened cloth or a small, soft-bristled toothbrush at least once a day, preferably just before bedtime.
Healthy teeth should be all one color. If you see spots or stains on the teeth, take your baby to a dentist.
When most of your child’s teeth are in, at about the age of 2, you can add a small drop of toothpaste to the brush. Also, ask your doctor or dentist if you need to use fluoride drops for your baby’s teeth. Well known for its use in preventing tooth decay, fluoride may not be added to your town’s water supply.
Around the time of your baby’s first birthday, call your dentist and ask when you should come in for the first checkup. Pediatric dentists usually want to see a child between the ages of 1 and 2 and then twice a year thereafter.
