All About Baby Teeth: Here's What to Expect

Once your baby's first tooth erupts, you should brush their teeth twice a day with a tiny amount of fluoride toothpaste (the AAP recommends it be the size of a grain of rice). This is especially important after the last meal of the day. Once your child is 3, the amount of toothpaste can increase to the size of pea. A parent or caretaker should do the brushing for their child, and continue to supervise brushing until they are 7 or 8 years of age.
