Can red light therapy help with periodontal disease?

If you notice your gums bleeding when you brush or floss, or you see your gums receding from your teeth, you may have early signs of periodontal disease. While mild gum disease can often be reversed with good oral hygiene, more advanced gum disease requires professional treatment. Along with dental cleaning and procedures, red light therapy is emerging as a helpful adjunct treatment to help strengthen gums, reduce inflammation, and ward off further gum recession. Read on to learn how red light could help boost your gum healing!

Can red light therapy help with periodontal disease?

What is Periodontal Disease?

Periodontal disease occurs when bacteria in dental plaque – the sticky film that covers teeth – cause inflammation and infection in the gums and bone that surround and support the teeth. As the disease progresses, the gums pull away from the teeth, forming spaces called pockets that become infected. The body’s immune system fights the bacteria as the plaque spreads and grows below the gumline. According to the American Academy of Periodontology, over 47% of adults over 30 have some form of periodontitis. Here are the main stages of gum disease progression:

Gingivitis – This is the early, milder stage of gum disease characterized by red, swollen gums that may bleed easily when brushing or flossing. At this stage, damage is limited to the soft tissue around the teeth.

Periodontitis – More advanced gum disease involving damage to the bone and ligaments supporting the teeth. Pockets form between the gums and teeth, which fill with bacteria and pus. The pockets deepen over time as tissue and bone are destroyed. Eventually, this can lead to tooth loss if not treated.

Advanced Periodontitis – In the most advanced cases, significant bone loss occurs, causing the teeth to become loose or fall out. Systemic health complications become more likely at this stage due to the spillover of bacteria and inflammatory compounds into the bloodstream.

Periodontal Disease Causes

A number of different factors can contribute to gum disease:

  • Poor oral hygiene – Not brushing and flossing properly allows plaque to build up on teeth near the gums. This plaque is filled with bacteria that irritate the gums.
  • Smoking or tobacco use – Tobacco users are much more likely to develop gum disease. The chemicals and heat from cigarettes, pipes, and other products damage gum tissues.
  • Hormonal changes – Puberty, monthly periods, pregnancy, and menopause can all increase inflammation and alter how gum tissues react to plaque.
  • Certain medications – Some drugs that treat conditions like epilepsy, heart disease, and high blood pressure can increase gum overgrowth and sensitivity.
  • Genetic predisposition – Research shows that up to 30% of the population may have inherited tendencies for gum disease.
  • Other illnesses – Diseases like diabetes, leukemia, and HIV/AIDS raise the risk as they limit the body’s ability to fight infection.
  • Stress – High levels of stress and anxiety may worsen gum inflammation in response to plaque bacteria.

Periodontal Disease Effects

Periodontal disease can lead to an array of detrimental effects in the mouth:

  • Gum inflammation and sensitivity – Red, tender gums that bleed easily are the initial signs of gingivitis. Inflammation worsens with periodontitis and advanced disease.
  • Periodontal pocket formation – Spaces or pockets form between the gums and teeth, creating reservoirs where bacteria multiply. Deeper pockets usually mean more severe disease.
  • Receding gums – Gums slowly shrink away from the teeth. Areas of exposed tooth roots become vulnerable to decay.
  • Halitosis (bad breath) – Pockets full of bacteria produce foul-smelling metabolic byproducts and gases.
  • Bone destruction – The infection spreads to the supporting alveolar bone causing loss of bone density and height.
  • Tooth looseness – Bone loss around the tooth eventually leads to loosening or even tooth loss.
  • Bite changes – Missing teeth and altered jawbone contours can shift teeth out of alignment and affect the bite.
  • Abscesses – Severe infections deep in the gums may create pus-filled abscesses requiring drainage.
  • Systemic effects – Periodontal bacteria and inflammation are linked to issues like respiratory disease, heart disease, and diabetes complications.

Clearly, allowing gum disease to progress leads to significant oral health destruction and mounting medical risks. That’s why it’s important to treat gum disease in its early stages before extensive damage occurs.

How Red Light Therapy Treats Periodontal Disease?

Red light therapy involves exposing the gums to red wavelengths of visible light in the 600-700nm range. Also called photobiomodulation, it provides beneficial therapeutic effects without damaging heat or side effects.

But how exactly can shining red light on inflamed gums and tissue possibly help counteract periodontal disease? Let’s review the main mechanisms at play:

1. Antimicrobial effects

Some wavelengths of red light are thought to be antimicrobial and can help control periodontal bacteria like P. gingivalis. The light may disrupt bacterial cell membranes and metabolism. This helps reduce plaque and bacteria loads to lower inflammation.

2. Improved microcirculation

Red light boosts beneficial nitric oxide levels and induces vasodilation of blood vessels. This brings more oxygenated blood and nutrients to repair damaged gum tissues.

3. Reduced inflammation

Red light exposure helps modulate immune cells and reduce secretion of damaging pro-inflammatory cytokines. It also limits tissue edema and swelling.

4. Cell proliferation

Red light stimulates fibroblast cells to increase collagen production and rebuild the structural framework of the gums.

5. Bone regeneration

It activates osteoblasts which lay down new bone matrix. This strengthens the jawbone and may help regenerate lost bone.

These unique mechanisms make red light therapy a potentially innovative approach to managing periodontal disease.

How Red Light Therapy Treats Periodontal Disease?

Research on Red Light Therapy of periodontal disease

There is also growing evidence that red light may improve treatment outcomes for more advanced periodontal disease involving bone loss and tissue damage. Here are some of the study findings:

  • In a 2018 clinical trial for chronic periodontitis, the prevalence of bacteria in the red light treatment group was significantly reduced compared with the control group after 1 month of treatment.
  • A 2019 clinical trial found that red light therapy combined with traditional scaling and root planing was significantly more effective than scaling and root planing alone in treating severe periodontitis.
  • Numerous studies have examined red light therapy, which, in addition to strengthening periodontal bone without surgery, can speed wound healing and reduce gum inflammation.

Safety Precautions for Red Light Therapy

Red light therapy is very safe for well-being when used correctly. However, a few basic precautions should be taken:

  • Consult your dentist – Speak with your dentist before trying red light therapy, especially if you have severe gum disease or dental issues.
  • Follow product guidelines – Carefully follow all safety directions from light device manufacturers. Don’t exceed recommended treatment times.
  • Protect eyes – Wear protective goggles when using handheld red light wands. Avoid shining the light directly into eyes.
  • Watch skin temperature – Red light can increase skin warmth. Stop if tissue feels uncomfortably hot.
  • Check medications – Red light may interact with some medications like antibiotics. Consult your pharmacist.
  • Clean mouthpieces – Disinfect any intraoral mouthpieces regularly to prevent bacterial overgrowth.

With proper use, red light therapy appears to have an exceptional safety profile. But taking sensible precautions maximizes its safe, effective use for better oral health.


As you can see, red light therapy may be a valuable complementary approach alongside conventional dental care. By combining red light therapy with proper dental care and healthy oral habits, you give yourself the best chance for a healthy mouth. So implement this promising treatment to start strengthening your gum tissues today!
