American alligators have similar tooth structure to humans They can regrow teeth up to 50 times! How can scientists mimic this for humans? Background
Dr. Rena DSouza has studied using stem cells from wisdom and baby teeth to regrow teeth pulp Ping Wu and his team are trying to replicate how alligators regrow their teeth Studies… PNAS Journal - Ping Wu
Regenerating tooth pulp can put an end to root canal procedures Possible full tooth replacement, ending dental implants Could lead to more bone and tissue regeneration Benefits
50% of Americans have a cavity that can lead to a root canal by the age of 15 Root Canals Pain Level Age MildSevereIntenseUnbearable 18-2011.8%18.2%50.0%0% 21-3029.4%18.2%33.3% 31-4029.4%31.8%16.7%66.7% 41-5017.6%31.8%0% 51-60 5.9% 0%
