You can never start too early when it comes to teaching your children how to take care of their teeth! Even before their 1st baby tooth is visible, (when they are around 6 months), you can start cleaning their gums and giving them something to chew on when they start teething. When your child is about 3 years old they should have all 20 of their baby teeth! Although they will most likely lose all of them by the time they’re 12, baby teeth still play a large role! They help children speak normally, chew, and also hold space in their jaws for their adult teeth to later come in.
