Regenerative Dentistry: Can Laser Help Regrow Your Teeth

Researchers are working on laser therapy that could regenerate damaged teeth naturally! Can this replace traditional fillings?

Highlights:

Low-power laser therapy has the potential to stimulate the body’s natural repair mechanisms to regenerate tooth tissue
Stem cells are specialized cells that have the ability to develop into various types of tissue
This treatment promotes natural healing, it can reduce the need for future dental procedures to replace failed restoration

Low-power laser (LPL) therapy is an emerging technology that promises to regenerate damaged teeth. Unlike traditional dental treatments that use artificial materials like fillings, LPL therapy has the potential to stimulate the body’s natural repair mechanisms to regenerate tooth tissue ().

What is Low-Power Laser Therapy?

Low-power laser therapy involves using a specific type of light that is much less intense than lasers used in surgeries. This type of laser is already used in medicine to treat pain and inflammation and to help stimulate healing in tissues such as skin and hair.

In dentistry, lasers are used in periodontal or gum treatments. LPL is now being explored for its potential to regenerate tooth tissue rather than rely on artificial materials.

Consuming too many sugary foods such as chocolates, pastries, soft drinks, and candies can increase the risk of dental cavities and inflammation of the gums (periodontal diseases).

How Does Low-Power Laser Therapy Work?

The treatment works by stimulating stem cells (biostimulation) within the tooth. Stem cells are specialized cells that have the ability to develop into various types of tissue. In the case of damaged teeth, stem cells can be prompted to form dentin, which is one of the main components of teeth, lying just beneath the outer enamel layer.

When a low-power laser is applied to the damaged tooth, it creates small molecules known as reactive oxygen species (ROS). These molecules activate certain signaling proteins in the body, which then signal the stem cells to start producing new dentin. The process results in the regeneration of tooth tissue, filling in cavities or repairing damaged areas.

Benefits of Regenerating Tooth Tissue

Traditional dental treatments, such as fillings, involve adding foreign materials to the tooth to restore function temporarily, they do not regenerate the tooth’s natural structure. Regenerating dentin with the body’s stem cells offers a more natural repair.
Artificial fillings and materials can wear down, crack, or cause complications over time. Regenerated dentin is likely to be more durable, potentially providing longer-lasting results.
LPL therapy is non-invasive, meaning it does not involve drilling or adding foreign materials. This makes it less likely to cause complications and can be a more comfortable option for patients.
Since the treatment promotes natural healing, it could reduce the need for future dental procedures to replace failing fillings or other materials.

Potential Applications in Dentistry

Currently, dentists fill cavities with materials like silver, gold, or resin, which are effective but do not replicate the tooth’s natural tissue. With LPL therapy, the body’s cells could regenerate the tooth’s dentin, restoring the tooth’s natural strength and structure.

This leads to fewer treatments, as the regenerated tissue is likely to be more durable than conventional fillings. While the technology shows great promise, further research and development are necessary to adapt it for widespread clinical use fully.

Specific techniques and equipment for applying the laser treatment safely and effectively to human teeth need to be refined. Additionally, dentists would need to develop methods to target the laser precisely to ensure effective stimulation of the stem cells.

Low-power laser therapy offers an exciting new approach to tooth regeneration, potentially changing the way dental caries can be treated. While more development is needed, this therapy holds significant promise for the future of dentistry, offering a less invasive, more effective alternative to existing treatments.
