School Age — Mixed Dentition
🎯 Milestone: A mix of baby and adult teeth — the 'ugly duckling' stage is normal!
- ✓Baby teeth start falling out — lower front teeth first (around age 6)
- ✓First permanent molars appear behind baby teeth (don't fall out!)
- ✓Continue supervising brushing until they can tie shoelaces independently
- ✓Use a mouth guard for sports — dental injuries are very common at this age
- ✓Discuss orthodontic evaluation around age 7-8
- ✓Limit sports drinks, cola, and juice — they erode enamel
- ✓Sealants on permanent molars are highly recommended

12–18 years
Teens — Permanent Teeth
🎯 Milestone: Wisdom teeth may start appearing between 17-21 years
