What are the two different sets of teeth that humans have?a)Milk teeth...
  • Humans have two sets of teeth.
  • The first set is called milk teeth, which we get when we are babies.
  • These teeth fall off when we are around six to eight years old.
  • The second set that grows in place of the milk teeth are called permanent teeth.
  • These teeth can last for a long time or fall off when we get old or if we have some problems with our teeth.
  • So, remember, we have milk teeth first, and then we get our permanent teeth.
