Is Fluoride toothpaste excess Safe for Babies 0–12 months?

0–12 months: Avoid

For babies 0–12 months, Fluoride toothpaste excess is best avoided. The American Dental Association and the American Academy of Pediatrics recommend fluoride toothpaste from the first tooth: a smear about the size of a grain of rice under age 3, then a pea-sized amount from 3 to 6 years, applied or supervised by an adult.

Why this rating?

The American Dental Association and the American Academy of Pediatrics recommend fluoride toothpaste from the first tooth: a smear about the size of a grain of rice under age 3, then a pea-sized amount from 3 to 6 years, applied or supervised by an adult. The concern this entry addresses is excess: swallowing a lot of fluoride while permanent teeth form can cause dental fluorosis, which is mainly cosmetic. Fluoride rinses are not recommended under age 6. Before the first tooth there is nothing to brush.

Editorial summary

This summary is editorial and is not part of the reviewed rating above. Ratings are unchanged.

At 0 to 12 months

Before the first tooth there is nothing to brush. Once a tooth appears, usually around the middle of the first year, the ADA recommends a smear of fluoride toothpaste about the size of a grain of rice, applied by an adult.

What the ADA and AAP recommend

The American Dental Association advises brushing with fluoride toothpaste as soon as the first tooth erupts, using a smear about the size of a grain of rice for children under 3 and a pea-sized amount from 3 to 6 years. The AAP gives similar guidance. Caregivers should do or supervise the brushing, because younger children swallow more toothpaste than older ones using the same amount.

Why excess is the issue

Swallowing a lot of fluoride while permanent teeth are forming can cause dental fluorosis, which is mainly a cosmetic concern and ranges from faint white flecks to brown spots or pitting of the enamel. The recommended amounts are designed to keep a child's fluoride intake from toothpaste below the level suggested by the National Academies. That is why this entry rates excess toothpaste as the concern, not fluoride toothpaste used in the recommended amount.

Other fluoride products

Over-the-counter fluoride rinses are not recommended for children under 6 because of the risk of swallowing. Teaching a child to spit out toothpaste instead of rinsing, as early as the child can learn, reduces how much is swallowed. Fluoride varnish applied by a doctor or dentist is a separate step recommended by the AAP from the time teeth appear.

In short

In short, use fluoride toothpaste from the first tooth, in the smallest amount that works, and do the brushing yourself. The problem this entry addresses is too much toothpaste, not fluoride toothpaste in the recommended amount, and a dentist or pediatrician can advise on your child's cavity risk and on the fluoride content of your drinking water.
