milk teeth are replaced by permanent teeth in human true or false
Answers
Answer:
Baby teeth ordinarily are shed first at about age 6 when the incisors, the middle teeth in front, become loose.
Molars, in the back, are usually shed between ages 10 and 12, and are replaced with permanent teeth by about age 13.
Children usually wiggle their teeth loose with their tongues or fingers, eager to hide them under their pillow for the "tooth fairy." If your child wants you to pull out the already loose tooth, grasp it firmly with a piece of tissue or gauze and remove it with a quick twist. Occasionally, if a primary tooth is not loosening sufficiently on its own, your child's dentist may suggest extracting it.
If your child loses his baby teeth by decay or accident too early, his permanent teeth can erupt prematurely and come in crooked because of limited space. According to orthodontists, 30 percent of their cases have their origins in the premature loss of baby teeth.
