What's the best way to brush my baby's teeth after they start coming in?

As your child's teeth start to appear (generally around 6 months), look for a baby toothbrush with a small bristle head and larger grip suitable for your hand. (If your child is healthy and still hasn't sprouted his first tooth by the end of his first year, don't worry — some children don't start getting them until 15 to 18 months.)

As long as you're cleaning your child's teeth regularly, you don't need to use any toothpaste yet. Just brush the teeth gently on both the outside and inside surfaces twice a day. Brush his tongue as well (if he'll let you) to dislodge the bacteria that can cause bad breath. One quick swipe is enough. Replace the toothbrush as soon as the bristles start to look worn or splayed out.
