Growth sequence of deciduous teeth
When the baby is 6 months old, deciduous teeth begin to erupt in the order of lower incisors → upper incisors → lower incisors → lower first molars → upper first molars → lower canines → upper canines → lower second molars → upper second molars. About two and a half years old, all 20 deciduous teeth have grown together!
Growth time of permanent teeth
Want to know how many permanent teeth a baby should have? Month age -(4-6) can be counted! For example, a 1 year-old baby should have 6-8 deciduous teeth. Permanent teeth began to erupt at the age of 6, and began to be replaced at the age of 12. But don't worry, when 18 years old, the number of permanent teeth will reach 32!
