Oral health not only plays an important role in eating but also impacts the beauty and confidence of every individual. However, issues related to oral health, especially damaged or lost teeth, remain a concern for many people. To address this problem, current methods typically focus on fillings, implants, or the use of artificial materials. But recently, scientists have discovered an entirely new method that can help regenerate teeth, a non-invasive technique that promises great potential in dental treatment: low-level laser therapy.

In an important study conducted by a group of scientists from the National Institute of Dental and Craniofacial Research (NIDCR) at the National Institutes of Health (NIH) and Harvard University, researchers tested the method of applying low-level laser light on the teeth of mice and found that this method could stimulate the regeneration of a crucial part of the tooth: dentin (a bone-like substance). After 12 weeks of testing, the research team observed a significant amount of new dentin formation, particularly in the teeth that had been exposed to the laser light.

To better understand the mechanism behind this method, the scientists discovered that the laser light could activate an important protein in the body called TGF-β, which helps stimulate the differentiation of dental stem cells into odontoblasts, the cells responsible for producing dentin. Interestingly, when the mice lacked the TGF-β protein or were treated with TGF-β inhibitors, they could not regenerate dentin after laser treatment, proving the important role of this protein in the tooth regeneration process.

The scientists stated that low-level laser light does not cause any side effects or harm to the body, which opens up the possibility of applying this method in human dental treatments in the future. One of the major advantages of this method is its non-invasive nature, ease of application, and low cost, making it ideal for developing painless dental therapies.

Currently, dentists are using lasers in various applications such as treating gingivitis, removing plaque, and whitening teeth. However, the use of lasers for tooth regeneration is still in the research and experimental phase. Experts predict that if this method is successfully developed and applied, it could be a breakthrough in dentistry, helping restore damaged tooth tissues without the need for fillings or artificial materials.

In particular, lasers can regulate this regeneration process without adding any foreign materials to the body. According to Dr. David Mooney, one of the research team members from Harvard University, this method would bring “a major advancement in the field of dentistry if we can regenerate teeth instead of replacing them.”

However, before applying this method to humans, scientists will need to develop more precise surgical techniques and light-focusing technologies to effectively apply it in clinical settings.

With significant progress in research, the low-level laser method for tooth regeneration is expected to usher in a new era for dentistry, offering a non-invasive and sustainable treatment solution for oral health issues in the near future.
