When do babies start teething?

The AAP says first teeth typically appear between 6 and 10 months, and that discomfort can start weeks or months earlier. Another AAP page says most babies get teeth between 6 and 12 months, and that some have none by their first birthday.

First teeth

The first teeth are almost always the lower front teeth. Most children have all their baby teeth by age 3.

Signs of teething

Teething can bring fussiness, drooling, more chewing, swollen and tender gums, and a rash around the mouth from drool.

The AAP says teething doesn’t cause fever, diarrhea or extra crying. If you notice any of these, call your pediatrician.

Soothing sore gums

  • Gently massage your baby’s gums with a clean finger.
  • Offer a soft rubber or plastic teething toy.
  • Twist and freeze a damp washcloth for them to chew. Don’t let them chew directly on anything frozen solid.
  • If your baby is over 6 months, offer cold water in a sippy cup.

If your baby seems very uncomfortable, ask your pediatrician what can help.

What to avoid

Numbing gels and treatments containing benzocaine or lidocaine, alcohol on the gums, and homeopathic teething tablets or gels.

Liquid-filled teething toys, and teething necklaces of any material.

Caring for new teeth

From the first tooth, brush twice a day with a rice-grain-sized smear of fluoride toothpaste. Make a first dental appointment after the first tooth comes in and by your baby’s first birthday.
