Low Level Laser Treatment Heals Damaged Teeth
Zapping damaged teeth with a low-power laser stimulates tooth repair according to a research study on
laser therapy that was published on May 28, 2014 in
Science Translational Medicine. The beams of light set off a molecular chain reaction that ends with the regeneration of dentin, the tough stuff inside teeth.
The study found that low-power
laser therapy can
stimulate dental stem cells (cells that have the ability to form into
other specialized tooth cells) to create dentin, the tooth layer under
enamel.
Researchers performed experiments on human dental stem cells to see if
laser therapy
would stimulate them to produce dentin. They also performed experiments
on rodents to see whether laser therapy could increase dentin formation
in damaged teeth.
Laser therapy did cause the dental stem cells to grow dentin in human tissue samples and rodents.
What Impact Do These Findings Have?
The fact that they were able to get dentin to grow could help alleviate
the need for root canal treatment, the painful procedure to remove dead
or dying nerve tissue and bacteria from inside a tooth.
Health Practitioners who are familiar with the principles of biological
dentistry have long known about the link between cancer and...
