Laser Light Treatment: Possibly Renewing Teeth in Future?

Most of us have a good chance of chipping or even breaking at least one tooth in our lifetimes.

If this happens to your or your child, you soon may see your Plano dentist fixing that chipped/broken tooth with a laser! reported in late May about research published in the journal Science Translational Medicine that found that a laser as strong as a sunny day is bright could regrow dentin (the material inside a tooth) in rodents.

Testing on people could begin within a year.

If continued research is successful, your dentist could help you regrow a broken tooth using a laser light.

The article also mentioned that the technique possibly could be used to regrow heart tissue, fight inflammation and repair wounds and bone.

If the procedure is effective during human trials and is brought into widespread use, it could transform medical care as we know it.

For example, instead of transplanting damaged hearts, livers, kidneys, lungs, etc. the treatment could allow patients to regrow their own organs!

Pathologist and dentist Praveen Arany, co-author of the research, said he decided to look more deeply into how light could lead to the regrowth of organs after hearing about light’s knack for repairing wounds and/or re-growing hair.

The laser light’s frequency needs to be something along the lines of “just right,” because low-frequency laser light does pretty much nothing and higher frequencies can cut tissue.

But at the “just right” level, the laser light looks as if it starts a chemical reaction that discharges what is called reactive oxygen species, a potentially dangerous type of molecule.

The body responds to the reactive oxygen by activating a protein known as Transforming Growth Factor (TGF)-beta (TGF-beta plays an important part in the development of embryos). In the case of the tooth research, the TGF-beta stimulated the creation of new dentin.

So far, researchers haven’t grown a whole new tooth; they just stimulated the growth of new dentin. Researchers, working now with the National Institute of Dental and Craniofacial Research, hope to find a means to grow a whole tooth.

If successful at growing a tooth, dentists may no longer have to drill and fill cavities.
