Red light therapy has surprising benefits for oral health. Here’s what the research shows.
Oral Health Benefits
1. Gum Disease Treatment
RLT can help with periodontal disease by:
- Reducing gum inflammation
- Killing harmful bacteria
- Promoting tissue repair
- Reducing pocket depth
2. Wound Healing After Dental Procedures
After extractions, implants, or surgery:
- Faster healing
- Reduced pain
- Less swelling
- Better tissue regeneration
3. TMJ/TMD Relief
For temporomandibular joint disorders:
- Reduces jaw pain
- Decreases inflammation
- Improves jaw function
4. Tooth Sensitivity
RLT may help with sensitive teeth by:
- Reducing nerve inflammation
- Promoting dentin repair
- Calming irritated nerves
Clinical Evidence
2019 (Journal of Photochemistry and Photobiology):
- LLLT reduced gum inflammation in periodontitis patients
- Improved healing after dental surgery
- Reduced pain scores
2017 (Lasers in Medical Science):
- RLT accelerated healing after tooth extraction
- Reduced post-operative pain
- Less swelling and bruising
