While there are many species that can regenerate their teeth, or have what appears to be an endless amount of teeth – but humans are not among those species. Humans are both with one set of baby teeth and one set of adult teeth. If you lose an adult tooth, the only options you have, other than no tooth, is a dental implant. Dental implants are incredibly costly, very painful to implant, and sometimes your body will reject the tooth anyways. Researches have found a couple of answers to this problem.
To begin with, in a collaborative study between the Georgia Institute of Technology and King’s College London studied the cichlid fishes of Lake Malawi in Africa as a basis of their research. These fish are known for being able to loose a tooth and then quickly produce a new tooth – time and time again. The focus of this study was to uncover the genetic component that these fish had to regenerate their tooth. With this information, researches could look into locating this gene in humans and work toward human tooth regeneration.
Another study out of the United Kingdom developed a new material that can be inserted into a tooth to repair and actually regenerate dentin. This material works similarly to regular fillings, which is inserted into the tooth and then hardened with UV light. With this material, once it is inside the tooth, it actually encourages the stem cells to proliferate and grow into the dentin itself.
