The age that your teeth stop regenerating is between the ages of 17 and 25 years of age.
Human permanent teeth stop erupting and stop developing between the ages of 17 and 25 years of age after your final wisdom teeth finish coming in.
Us humans only get 2 sets of teeth in our lifetime, which are our baby teeth and our permanent teeth.
And once your permanent teeth are lost as an adult, the permanent teeth don't grow back.
By ages 6 to 12, children lose their 20 baby teeth and then permanent adult teeth replace those lost baby teeth.
By ages 12 to 13, most of our human teeth are in place fully, except for our back molars.
By ages 17 to 25, our wisdom teeth (third molars) show up last, marking the final stage of any new adult teeth emerging.
Us humans are born with a fixed number of tooth buds, which are 20 tooth buds for baby teeth and 32 tooth buds for adult permanent teeth.
There are also no extra tooth buds left in the human jaw to create a third set of teeth once you lose your adult teeth.
If an adult tooth falls out as a result of injury or tooth decay, the human body can't regenerate any new replacement teeth.
If you lose your teeth as an adult you either need to get dentures or get dental implants to replace them or do without the teeth if you can't afford dentures or dental implants.
This is why it's so important to brush and floss your teeth often enough and use mouthwash as well and get regular dental checkups to ensure your teeth are healthy and remain healthy.
