how old grow molars teeth
Auremar/PhotoSpin. Significant Dental Milestone. Six years of age is a big milestone where your childâs mouth is concerned. It is around this age that your child will start to lose teeth and make room for the adult teeth. But this whole adult tooth stage actually starts with the eruption of the six-year-old molars. These molars will come in behind the last deciduous (baby) molar. The six-year-old molars are the âfirst molarsâ and set the boundary that will help all the other adult teeth align in the mouth.
