What does dentistry and stem cell research have in common? The answer may be more enlightening than you can imagine. Scientists are working diligently to discover the abilities of cell regeneration within the human body. Dentistry is playing an important role in this new age research.
Is it possible that the days of the root canal could finally be numbered? Yes. It may even be sooner than you think. A root canal procedure involves cleaning out the infected and dead tissue in the root canal of the tooth, disinfecting the area, and adding an impermeable seal to try to prevent further infection. An estimated 15.1 million root canals are performed in the U.S. annually, according to a 2005-06 survey by the American Dental Association.
Elimination of root canals would be a huge paradigm shift in dentistry. As a biological dentist, I welcome this change in the practice of dentistry. My major concern about a root canal is that, although we may eliminate the pain and infection that patients initially experience, we cannot create a sterile environment inside the dentinal tubules. Also, the seal that is carefully placed at the apex of the tooth does not always prevent new infection from occurring. This compromised condition could subsequently spread to surrounding tissue without detection and eventually develop unexplained or mysterious illnesses in other areas of the body. (See the Tooth/Organ Chart and its connections to other major organ systems on our website at toothbody.com.)
Current research shows that advances made by scientists in treating tooth decay may allow dentists to restore tooth tissue and avoid the dreaded root canal procedure. Several recent studies have demonstrated in animals that procedures involving tooth stem cells appear to regrow the critical, living tooth tissue known as pulp.
Treatments that prompt the body to regrow its own tissues and organs are known broadly as regenerative medicine. There is significant interest in figuring out how to implement this knowledge to help the many people with cavities and disease that lead to tooth loss.
According to the Centers for Disease Control and Prevention, in the U.S. half of kids have had at least one cavity by the time they are 15 years old and a quarter of adults over the age of 65 have lost all of their teeth. Tooth decay arises when bacteria or infections overwhelm a tooth’s natural repair process. If the culprit isn’t reduced or eliminated, the damage can continue. If it erodes the hard, outer enamel and penetrates down inside the tooth, the infection eventually can kill the soft pulp tissue inside the tooth, prompting the need for either a root canal or removal of the tooth. Pulp is necessary to detect sensation, including heat, cold, and pressure. It contains the stem cells (undifferentiated cells that turn into specialized ones) that can regenerate tooth tissue.
Researchers from South Korea and Japan to the U.S. and United Kingdom have been working on how to stimulate dental stem cells into regenerating pulp. The tooth is considered nature’s “safe” for these valuable stem cells. There is an abundance of stem cells in baby teeth, wisdom teeth, and permanent teeth. The process is still in its early stages, with only a few reports of experiments in humans, however, if successful, it could mean a reduction, or even elimination, of the need for painful root canals.
A 2009 nationwide survey by Nova Southeastern University (NSU) revealed that 96% of the dentists polled expected stem cell regeneration to dominate the future of dentistry. Additionally, more than half predicted that the technology would be available within the next decade.
What an exciting time to be in dentistry. Stem cell regeneration will certainly reform the practice of dentistry in a positive manner. I believe sooner than later we’ll witness the day when dentists will be moving away from traditional root canal treatments and reduce or eliminate the need for extracting teeth due to extensive dental decay. Beautiful, healthy teeth will finally be the norm instead of the exception.

Hello, I have a dentist and also have dental insurance. I have been told that I need a root canal on one of my molars. I am very interested in an alternative however. Do you take Cigna thru AT&T and are you accepting new patients?
Yes, we are currently accepting new patients. While we aren’t preferred providers for any insurance, we do submit claims for our patients to all insurance companies – most often electronically and on the date of service.
It is possible to regenerate tooth after root canal
No. Once a root canal is done, the tooth is dead.
is the root canalled teeth available for a regeneration once the dental stem cell theraphy is released into the market ? when will the stem cell dental be available ? I understand the research dated back to 2010/2013
pls enlighten me on this crucial matter
The research on stem cell regeneration is still going on, and we don’t know of any projected date when such therapy may be available.
hello Dr.Rehme, I’m a 42 year-old male and I was very pleased to know more about tooth regeneration and the problems due to root canals. I’m quite concerned about the latter and the implications in my health, as I have at least 5 root canals, two of them with ceramic crowns. In your opinion, is it safer to replace them with implants or use a removable partial denture?thank you so much for your attention
There’s some debate among biological dentists as to the safety of implants. Some say they’re fine as long as they’re ceramic and biocompatible. However, research by Hal Huggins, among others, has suggested that *any* foreign body tends to produce autoimmune responses. According to Professor Doug Swartzendruber of the University of Colorado, “Anything implanted into bone will create an autoimmune challenge. The only difference is the length of time it takes for a disease to appear.”
In light of such concerns, partials are the better way to go. And with the light, flexible, biocompatible materials available today, they’re a better option than ever.
I’ve been searching for a dentist office that does stem cell fillings. Is there on in the northglenn/ Thornton area you can direct me to?
Regenerating teeth with stem cells is still in the experimental stage. This blog post discusses the matter nicely: http://www.biologicaldentist.com/3790/theres-no-regrowing-teeth-not-yet-anyway/
I am 23 now and having two root canals in my front incisors, can I regrow new teeth with this technique if so when will it be available
It remains in the experimental stage at this point.
I am sudharsan age 24 i am infected with 4 teeth. Alreay i have done 2 Rc without knowledge of this stem cell retooth natural growing . .now doctors forcing me to do another two RC or condition may even get worse…. i have oly few options 1, Rc 2, post Rc 3, taking the tooth completely 4. Implants.. They are telling after Rc no life force to teeth so dont worry… i amble request try to find after Rc also natural replacement can be possible not me everyone will be happy..
Hi, Sudharsan. Thank you for reaching out. We’re sorry to hear of your situation. Stem cell regeneration is still in the experimental stages and is not something any dentist can currently provide. So the only options for replacing teeth are bridges, partials, and implants. You can read about the pros and cons of each of these options here: https://toothbody.com/hey-tooth-you-can-be-replaced/. And you can read about the issue of keeping root canal teeth here: https://toothbody.com/?s=root+canal&submit.x=0&submit.y=0. We hope this information helps!
