Dental care begins long before the first tooth “pops.” Following these age-specific milestones ensures your child develops a healthy foundation for their permanent teeth.

0 to 6 Months: The Pre-Teething Phase

Even without visible teeth, oral bacteria can build up on the gums.

  • Oral Hygiene: Gently wipe your baby’s gums with a clean, damp washcloth or gauze after feedings.
  • Nutrition: Infants should be exclusively breastfed for approximately the first 6 months of life
  • Avoid “Bottle Propping”: Never leave a baby with a bottle in their crib. This prevents “Baby Bottle Tooth Decay,” caused by prolonged exposure to milk sugars.

6 to 12 Months: The First Tooth & The First Visit

Most babies get their first tooth (usually the lower central incisors) during this window.

  • The “First Visit” Rule: The AAP recommends your baby see a dentist within six months of the first tooth appearing, or by their first birthday.
  • Brushing Begins: As soon as the first tooth erupts, start brushing twice a day (morning and night).
  • Fluoride Guidance: Use a “smear” of fluoride toothpaste no larger than a grain of rice, specific to their age.

12 to 24 Months: Establishing Routine

As more molars begin to emerge, the risk of trapped food increases.

  • Weaning the Bottle: The AAP suggests transitioning fully from the bottle to a cup by 15 months to prevent pooling of liquids around the teeth.
  • Dietary Habits: Limit 100% fruit juice to no more than 4 ounces per day, though whole fruit is preferred. Avoid all sugar-sweetened beverages.
  • The “Lift the Lip” Check: Continue monthly inspections. Look for chalky white spots (early decay) or dark spots (cavities).

3 Years and Up: The “Pea-Sized” Transition

By age three, most children have all 20 of their primary teeth.

  • Toothpaste Increase: You can now increase the amount of fluoride toothpaste to a pea-sized amount.
  • Spitting Practice: Teach your child to spit out the excess toothpaste rather than swallowing it.
  • Supervision: While toddlers want independence, the AAP recommends parents continue to brush their child’s teeth (or provide a “thorough follow-up” brush) until the child is at least 7 or 8 years old.

Symptom Management: Teething vs. Illness

It is a common misconception that teething causes high fever or diarrhea. According to the AAP:

  • Normal Teething: Low-grade temperature (under 101°F or 38.3°C), fussiness, and increased salivation.
  • Not Teething: If your baby has a fever over 101°F, vomiting, or a persistent cough, these are likely signs of a viral illness and require a call to your pediatrician.

Recommended Soothing Techniques

  1. Manual Pressure: Use a clean finger to rub the gums.
  2. Cold Objects: Use solid (not liquid-filled) teething rings or a cold washcloth.
  3. Medication: Use acetaminophen or ibuprofen only under a doctor’s guidance. Avoid topical teething gels containing benzocaine or belladonna, as the FDA and AAP have issued warnings against them for infant safety.
