Could Laser Treatment Replace Getting A Root Canal?

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...
