When teeth come in

Most babies get their first tooth, usually a bottom front tooth, between about 4 and 7 months. The rest arrive gradually, and most children have all 20 baby teeth by about age three.

Common signs

What teething doesn't cause

Teething doesn't cause high fevers, diarrhea, rashes all over the body or serious illness. If your baby has a fever of 100.4°F (38°C) or higher, or seems unwell, call your pediatrician rather than assuming it's teething.

Safe ways to soothe

If your baby is very uncomfortable, ask your pediatrician whether a pain reliever is appropriate and at what dose.

Products to avoid

Pacifier clips

If you use a pacifier clip, use it only while your baby is awake and supervised. Never attach a pacifier to a cord around the neck, and remove clips during sleep.

Caring for the first teeth

As soon as the first tooth appears, brush twice a day with a soft infant toothbrush and a smear of fluoride toothpaste the size of a grain of rice. Schedule a first dental visit by the first birthday.
