🦷 When Do Babies Start Teething?

Everything you need to know about teething: when it starts, what to expect, and how to comfort your baby.

When Does Teething Begin?

Most babies get their first tooth between 4 and 7 months, though some start at 3 months and others after their first birthday. Both are normal. By age 3, most children have a full set of 20 primary (baby) teeth.

💊 Safe Teething Remedies

✅ Recommended

  • Chilled teething rings — refrigerate (don't freeze)
  • Clean, wet washcloth — chill and let baby chew on it
  • Gum massage — gently rub gums with a clean finger
  • Infant acetaminophen/ibuprofen — for babies 6+ months, as directed by pediatrician

❌ Avoid

  • Benzocaine gels (Orajel) — FDA warns against use under age 2
  • Teething necklaces — choking and strangulation risk
  • Frozen teething toys — too hard, can hurt gums
  • Homeopathic tablets — FDA found potentially harmful ingredients

🪥 First Tooth Care

Start cleaning gums with a soft, damp washcloth before teeth appear. Once teeth emerge, brush twice daily with a soft infant toothbrush and a rice-grain-sized smear of fluoride toothpaste. Schedule the first dental visit by age 1.
