  • Is orthodontic treatment needed now or later?
  • How do I help my child brush independently but effectively?
  • What should my child eat for school lunch to protect teeth?

When to call the doctor

  • Untreated caries in primary molars (can affect permanent successors).
  • Enamel hypomineralization (chalky white or yellow/brown spots on molars).
  • Ectopic eruption of first permanent molars (stuck under adjacent primary tooth).
  • Class II or Class III malocclusion requiring functional appliance.
  • Persistent thumb sucking or pacifier use after age 4.
  • Ankyloglossia (tongue-tie) affecting speech or oral hygiene.
  • Multiple missing teeth (hypodontia) or supernumerary teeth (hyperdontia).

Parent Tips

  • Supervise brushing until at least age 7-8; use disclosing tablets to show missed plaque.
  • Place dental sealants on 6-year molars within 6 months of eruption (ideal).
  • Encourage crunchy fruits/vegetables as natural tooth cleaners (apples, carrots, celery).
  • Limit sugary drinks and sticky candies (gummies, caramels, licorice).
  • Schedule orthodontic evaluation by age 7 to intercept developing problems.
  • Establish a dental emergency plan (avulsed tooth: keep moist, see dentist immediately).
  • Drink fluoridated tap water; avoid bottled water without fluoride.
