If your baby does not want to open for you, place your finger near the mouth, and then it will open slowly as your baby will think that you are trying to offer food. Even if your baby tries to bite down on your finger, be patient, keep trying, and the mouth will soon open up again. Reach inside along the cheek until you get between the upper and lower gums, and your baby will then open more to allow you to wipe the gums in the very back. If you find that one or more ulcers appear in your baby’s mouth, just clean around the ulcer until it are healed (usually within one week). Get your child accustomed to cleaning the mouth regularly and going to bed with a clean mouth.
