Teeth Nerve Stem Cells Signal New Age of Recovery
Have you ever thought about the possibility of growing new teeth? Of course, when we are younger, this phenomenon does occur, with adult teeth replacing our missing baby teeth. Many scientists and doctors, however, believed it was impossible, or highly unlikely for adults to ever form new teeth.
Yet only recently, researchers in Sweden have discovered that such a feat may one day become commonplace. While most scientists did know that the pulp in teeth contains a certain amount of stem cells, the Swedish researchers of the Karolinska Institute have discovered the origin of these cells.
These stem cells are typically used to help reform damaged teeth by assisting with the restoration of tooth tissue. Upon further examination, however, the researchers have discovered that these stem cells originally were nerve cells of the tooth. These cells leave the nerves at early stages of development, changing their identity to become part of the connective tissue, which forms dentin underneath the enamel.
The future possibilities for this discovery are almost endless. Using these nerve tissues, it may be possible for scientists to manipulate the stem cells to form new adult teeth. As these teeth will essentially be copies of one’s original teeth, this innovative process may replace veneers and other restorative processes as the best form of teeth restoration.
In fact, the benefits of this discovery may not stop with just teeth. Igor Adameyko, from Sweden’s Department of Physiology and Pharmacology, believes that all types of peripheral nerves, not just the ones found in teeth, “may function as important stem cell reserves.” Adameyko hypothesized that these “multipotent stem cells can depart from the nerves and contribute to the healing and reformation of tissues in different parts of the body.”
To summarize this exciting research, tooth nerve cells may be the key to a new wave of human recovery and restoration, and adult tooth creation is only one of these recently discovered benefits!
