1. Teeth development
   32 permanent teeth replace baby teeth between the ages of 6 and 20.
   By the age of 12, most children will have all permanent teeth, but third molars (wisdom teeth) will grow around the age of 18-20.
2. Cleaning teeth
   Brushing teeth is crucial for maintaining tooth cleanliness, preventing cavities, bad breath, and gum disease.
   But teenagers don’t always brush their teeth, which may have many reasons.
   For example, your child may not understand the importance of brushing teeth and gums, or they may just forget to do so.
   Try to pay attention to signs of children not brushing their teeth.
   For example, their toothbrush has not been used, their teeth may not look clean, or their gums may swell or bleed, or they may have bad breath.
   You can encourage your child to brush their teeth twice a day.
   Discussing why brushing teeth is beneficial may be a good starting point.
