Science of Regrowing Teeth

Technological advances within the field of science have brought about many great advancements over the years. Research scientists are experimenting with ways to actually grow teeth from stem cells. By the use of laser and stem cells, it may be possible to grow normal healthy teeth in humans.

In fact, a team of dentists have even used rodents to see if they were able to regrow teeth by using a laser instrument and stem cells. First, the dentist drilled a series of holes in the teeth of laboratory rats. After the holes were drilled in the tooth of the rat adult stem cells were applied to the pulp portion of the remaining tooth. Humans also have pulp which can be found in adult human teeth. The stem cells were applied by using a low powered laser. Only a low powered laser may be used in a procedure of this nature.

After the laser was applied to the tooth, the dentist constructed a temporary cap and placed it over each tooth of the rat. Over the next 10-12 weeks, the teeth were carefully observed through x rays and by simply looking at the teeth with the naked eye. Through careful observation over a 12 week period, it was noticed that under a thin layer of enamel the tooth had in fact begun to grow.

This is a very complex procedure and it is unknown whether or not this procedure could be used in place of common dental procedures. Regrowing teeth is a procedure that is so complex because it involves stem cells and various proteins that are found in human as well as animal saliva.

Stem cells are also being used in an effort to rebuild a jawbone so dental implants may fit securely. Stem cells have been found useful to treat a number of ailments and defects. However, stem cell research and application is still considered by many as controversial.

If this procedure can help humans to grow teeth in the future it would certainly be a real breakthrough as far as medical science and dentistry are concerned. Due to the fact that this procedure involves the manipulating of cells and proteins, it is considered quite complex and more research and testing may be needed.

The Business Insider also published an article and photo which illustrated how the teeth begin to regenerate after treatment with a low power laser and stem cells. The photo was quite impressive and gives the public some insight on what the future of science may hold.

Growing teeth is considered to be regenerative medicine and may one day replace the root canal as well as other dental procedures. Additional research and testing is currently underway.
