The main component of yogurt is lactic acid bacteria. If you drink too much or don't rinse your mouth in time after drinking it, it will cause lactic acid bacteria to mix with mucin and food scraps in saliva, firmly adhere to the tooth surface and pit and fissure, form dental plaque, and cause decalcification and dissolution of tooth enamel surface, resulting in dental caries. Children's deciduous teeth erupt from six months to two and a half years old. The newly erupted teeth are not well developed, with low calcification and poor acid resistance. When the PH value in the mouth is high, it is easy to corrode the enamel on the tooth surface, resulting in decalcification of teeth and eventually forming dental caries.

However, there are many reasons for children's dental caries. Some children like to drink fruit juice and cola drinks, which are rich in sugar and high in acidity, creating favorable conditions for the occurrence of dental caries. At the same time, children eat less cellulose food, so they can't automatically clean the tooth surface through the friction when chewing food. So the incidence of dental caries in children is very high.

To avoid the occurrence of dental caries in children, parents should patiently help their children clean their mouths every day from the eruption of deciduous teeth. Help your child clean his teeth with a fingertip silicone deciduous tooth brush. Parents should teach their children to brush their teeth after they are 3 years old.
