Children’s oral hygiene

0 to 2 years

Wipe gums with a gauze or silicone finger brush. Once teeth erupt, brush twice daily with a rice‑grain smear of fluoride toothpaste as advised by your dentist.

3 to 6 years

Supervise brushing twice daily. Use a pea‑sized amount of fluoride toothpaste and teach spitting (no vigorous rinsing). Start flossing once teeth contact each other.

7 to 12 years

Refine technique (2–3 minutes, by quadrants) and keep daily flossing (with help when needed). Discuss sealants and professional fluoride based on caries risk.

Routines and tools

  • Frequency: twice daily (after breakfast and before bed).
  • Brush: soft bristles, small head; replace every ~3 months.
  • Fluoride toothpaste: concentration and amount tailored to age and risk, under dental guidance.
  • Floss: daily wherever teeth touch.

Diet and habits

  • Limit sugary drinks and snacks between meals; choose water and whole fruits.
  • Avoid putting the child to sleep with milk/juice bottles; if needed, only water.
  • Reduce sticky sweets that cling to teeth.

Dental visits

First visit around the first tooth or first birthday. Follow‑ups every 6–12 months depending on individual risk. Sealants on permanent molars significantly reduce caries risk.

Quick checklist

  • 0–2: wipe/soft brush, tiny smear of fluoride paste.
  • 3–6: supervised twice‑daily brushing, pea‑sized paste, floss when contacts exist.
  • 7–12: 2–3 min technique, daily flossing, consider sealants and professional fluoride.

FAQs

When can kids brush alone? Around 7–8 years, but supervise until they manage time and technique consistently.

What if they refuse to brush? Make it fun (songs, timers, apps), use positive reinforcement and keep a steady routine.
