Many children are not brushing their teeth correctly, or they are using too much toothpaste, which is not healthy in teeth formation years. Getting children to clean the teeth rightly requires parental supervision, US researchers suggest.

The Centers for Disease Control and Prevention (CDC) and paediatrician groups advise parents to start to brush infants’ teeth when the first tooth begins appearing. Moreover, they recommend parents to help and supervise kids in brushing until the children are independent enough to do so.

Ingesting too much fluoride can harm still-forming teeth, the study team notes in CDC’s Morbidity and Mortality Weekly Report. CDS’ findings show over 38 per cent of kids from 3 to 6 years old use more toothpaste than the CDC’s advice.

CDC does not recommend use of fluoride toothpaste for kids under two years. They suggest a rice-grain size amount of toothpaste for children under age 3 and a pea-sized amount for kids above 3 years.
