To remove plaque from baby teeth, parents can use a damp toothbrush or cloth and introduce floss as soon as children have two teeth side by side. Regular visits to the dentist are a must, too.

Throughout the day, a sticky coating of plaque forms on the teeth and traps the sugars from the foods your child eats. If this substance isn’t properly brushed off teeth, the bacteria in the plaque will release acids that break down the enamel and form holes (cavities) in the tooth.

Cavities are caused by plaque (plak). Plaque is a harmful layer of bacteria that forms on the teeth. When your child eats food or takes medicine that has sugar in it, the bacteria produce acids. These acids harm the teeth and make cavities form. Cavities happen faster in baby teeth than in adult teeth.

Baby teeth, also called primary teeth, are typically whiter than adult permanent teeth because they are more calcified. Baby teeth can become discolored for many reasons, including: Inadequate brushing. If baby teeth aren't brushed properly, bacteria (plaque) might form on the teeth — which can lead to tooth discoloration.
