At the age of seventeen, new teeth will not erupt after the loss of large teeth (clinically known as molars), and restorative treatment for missing teeth is required.
Molar teeth mainly include the first permanent molar, the second permanent molar and the third permanent molar, the first permanent molar eruption time is the earliest, about the age of six years old began to erupt; the second permanent molar about twelve years of age eruption, eruption time is later; the third permanent molar (i.e., wisdom teeth) generally in the age of sixteen years old after the eruption of the last eruption of molar teeth.
Therefore, there will be no new teeth erupting at the age of seventeen when the molars are missing because all the permanent molars have already erupted; there will be no replacement teeth for the missing permanent molars. It is recommended to seek restorative treatment (removable denture, fixed denture or implant denture, etc.) in order to restore the normal chewing function of the mouth.
