Tips for Brushing
Make brushing fun by starting with a toothpaste that has a flavor your kids will enjoy, such as Colgate's watermelon or strawberry-flavored toothpaste. Involve your child in picking out a toothbrush to get them excited about toothbrushing. Toothbrushes should be soft-bristled to avoid damaging the gums. They can be used for about 3 months, and then they should be replaced. If your preschooler gets sick, pediatricians recommend replacing his toothbrush once he is healthy again.
After age two, your preschoolers can use a pea-size drop of fluoride toothpaste (rather than just water and a toothbrush). You can ask your child to open wide so that you can brush your children's teeth for them, or you can teach your kids to brush from left to right for two minutes. Set a timer for brushing to help ensure that they brush every tooth, from the incisors to the molars. Make sure your kids spit out the toothpaste when they are finished. Fluoride toothpaste can only be swallowed in very small amounts.
Brushing should be done at least twice a day. If your child eats something sugary, he should brush when he is finished, or, at the very least, rinse his mouth with water.
Mouthwash should not be used until your child has learned to spit it in the sink and rinse his mouth properly, which typically happens around age six.
