A set of human teeth under an orthopantomogram. Tooth regeneration is a stem cell based regenerative medicine procedure in the field of tissue engineering and stem cell biology to replace damaged or lost teeth by regrowing them from autologous stem cells.
As a tooth is forming, a force can move the tooth from its original position, leaving the rest of the tooth to form at an abnormal angle. Cysts or tumors adjacent to a tooth bud are forces known to cause dilaceration, as are primary (baby) teeth pushed upward by trauma into the gingiva where it moves the tooth bud of the permanent tooth.
With about 1 percent of humans suffering from anodontia, a genetic condition that doesn’t allow a full set of teeth to grow, there is hope for teeth regrowth in humans beyond just mice-centric ...
Traditionally, the management of hypodontia has involved replacing missing teeth. By replacing the missing teeth, it can prevent neighbouring teeth tilting or drifting and also prevents the overeruption of opposing teeth which could then impact on occlusion and temporo-mandibular joint dysfunction and impact the patient's susceptibility to gum ...

Researchers are confident that tooth regeneration technology can be used to grow live teeth in people. In theory, stem cells taken from the patient could be coaxed in the lab turning into a tooth bud which, when implanted in the gums, will give rise to a new tooth, and would be expected to be grown in a time over three weeks.

The vas deferens can grow back together after a vasectomy–thus resulting in vasectomy failure. [40] This occurs due to the fact that the epithelium of the vas deferens, similar to the epithelium of some other human body parts, is capable of regenerating and creating a new tube in the event that the vas deferens is damaged and/or severed.

In general, the non-growing subjects and growing subjects would exhibit different signs and symptoms. [4] Individuals suffering from ankylosis of deciduous teeth risk of losing these teeth due to the failure of the tooth eruption during facial growth and would lead to a series of functional and esthetic problems.
