✅ Timing is different for every baby. Most babies get their first tooth between 6–12 months, but some won’t have one by their first birthday—and that’s totally okay! Usually, the bottom front teeth (lower central incisors) are the first to appear.
✅ Fluoride matters. Starting at 6 months, introduce a few ounces of tap water (if it contains fluoride) in a sippy cup. Fluoride strengthens tooth enamel and helps prevent cavities.
✅ Soothe teething safely. Massage sore gums with a clean finger, offer a cold (not frozen) teething toy or washcloth, or use a weight-appropriate dose of acetaminophen (or ibuprofen if over 6 months) if needed. Avoid teething gels, tablets with benzocaine or belladonna, and amber teething necklaces—they can be unsafe.
✅ Start brushing early. As soon as the first tooth appears, brush twice daily using a smear (rice-sized amount) of fluoride toothpaste. Once your child is 3, switch to a pea-sized amount. Keep helping them brush until they’re around 7 or 8.
✅ Ask about fluoride varnish. Your pediatrician can apply fluoride varnish to your baby’s teeth during checkups—this protects against early cavities.
✅ See a dentist by age 1. Make your baby’s first dental appointment once the first tooth erupts or by their first birthday. Establishing a “dental home” early ensures healthy oral development.
Why This Matters
Good oral health starts before your child can even say “tooth.” By introducing healthy habits early, you help prevent cavities, set up a positive relationship with dental care, and teach lifelong hygiene skills.
