How Red Light Therapy Helps To Heal Teeth And Gums?

A beautiful, healthy smile can do wonders for your confidence and quality of life. But for many people, achieving great oral health seems out of reach. Gum disease, cavities, and other issues can leave you feeling frustrated and hopeless. However, exciting new research shows that red light therapy offers a natural, drug-free way to significantly improve your dental health. Once available only in dentist offices, now red light devices are affordable for home use. Let’s look at the evidence, and why you can benefit.

How Red Light Therapy Helps To Heal Teeth And Gums?

The Importance of Teeth and Gums to Overall Health

Our teeth and gums are crucial to our overall health and wellbeing. Not only do they allow us to chew and digest food properly, but they also enable us to speak clearly and smile confidently. Poor oral health has been linked to many medical conditions including heart disease, diabetes, stroke, and dementia. This is why it’s so important to take care of our teeth and gums.

Healthy teeth and gums start with good oral hygiene. Brushing twice a day, flossing daily, and regular dental checkups and cleanings help prevent cavities, gum disease, and other dental problems. However, sometimes even with good hygiene, our teeth and gums can become damaged or inflamed. This is where therapies like red light can help.

Common Causes of Poor Teeth and Gums

Many factors can contribute to poor dental health over time. Being aware of these causes can help you take preventative action:

  • Poor Oral Hygiene – Not brushing and flossing properly leads to plaque buildup and cavities. Insufficient cleaning also causes gum disease.
  • Unhealthy Diet – Foods high in sugar and acidic drinks like soda can damage tooth enamel and irritate gums.
  • Smoking and Tobacco – Smoking discolors teeth, causes gum recession, and increases the risk of oral cancer. Smokeless tobacco erodes enamel.
  • Grinding and Clenching – Putting pressure on teeth wears down enamel and chips teeth over time. Night guards can help prevent damage from bruxism.
  • Genetics – Some people are naturally prone to dental problems like soft enamel or sensitive gums. Genetics aren’t destiny, however. Proper care can offset risks.
  • Dental Injuries – Sports collisions, accidents, and traumatic bites can crack, knock out, or fracture teeth. Mouthguards and prompt treatment help minimize damage.
  • Poor Dental Work – Defective fillings, ill-fitting crowns, and undetected decay under restorations can lead to issues. Seek a second opinion if you suspect any problems.
  • Dry Mouth – Lack of saliva increases cavities and gum disease. Some medicines and health conditions cause chronic dry mouth. Staying hydrated helps.
  • Substance Abuse – Heavy alcohol and drug use often corresponds with dental neglect. The chemicals themselves also damage teeth and gums over time.

Fortunately, red light therapy provides a non-invasive way to improve many of these common dental problems.

What is Red Light Therapy?

Red light therapy, also known as photobiomodulation or low-level laser therapy (LLLT), is the use of red and near-infrared light to stimulate, heal, and regenerate tissues in the body. It has unique healing effects on our cells. When absorbed, red light energizes mitochondria, the powerhouses in our cells. This boosts adenosine triphosphate (ATP) production. ATP gives cells the energy they need to repair damage and rejuvenate tissues.

Dentists began using red light therapy over 40 years ago with lasers. But the high cost limited access. Now with affordable LED devices, you can get these healing benefits at home.

Red light penetrates tissue deeply. It promotes blood flow and stimulates collagen production. It also reduces oxidative stress and inflammation. These combined effects explain why it improves gum health and repairs teeth.

Benefits of Red Light for Teeth and Gums

An increasing body of research substantiates the use of red light therapy as an effective treatment for damaged or diseased gums. Red light reduces inflammation, repairs tissue, regenerates bone, and reduces dental hypersensitivity. It also has antimicrobial properties to combat periodontal pathogens. Here are the main benefits of using red light therapy for your mouth:

Red Light Therapy Strengthens Gums And Prevents Gingivitis

Gum disease affects over 50% of adults worldwide, making it a leading cause of tooth loss. Bacteria in dental plaque produce toxins that inflame the gums, causing them to pull away from the teeth. As periodontal pockets deepen, more plaque accumulates and chronic gum disease can develop.

Red light therapy helps treat and prevent gingivitis in two key ways:

  • Reducing Inflammation: The light decreases inflammatory cytokines and immune cell activation. This eases swelling and discomfort in irritated gums.
  • Improving Circulation: It increases blood flow to deliver more oxygen and nutrients to gum tissue. This optimizes healing responses.

In one study of hundreds of children with chronic gingivitis, those who received red light therapy were more effective at curing their gingivitis than a control group.

Red Light Therapy Fights Cavities and Tooth Decay

Dental cavities form when acid produced by bacteria erodes tooth enamel. If left untreated, cavities progress through deeper tooth layers until they reach the nerve. Red light therapy supports dental health by suppressing cavity-causing bacteria and rebuilding decayed areas.

In one study, 30 subjects with chronic periodontitis underwent red light therapy. Red light therapy significantly reduced the growth and viability of several bacterial species compared with the control group.

Red light also stimulates minerals like calcium and phosphate to regenerate hydroxyapatite crystals that comprise tooth enamel. This remineralization process essentially reverses early caries lesions, filling in microscopic defects before they turn into large cavities.

Moreover, red light boosts dental pulp cell metabolism and dentin formation. This further enhances the teeth’s natural repair processes from within.

Speed Implant Healing and Integration

Dental implants can beautifully restore smiles impaired by injury or decay. But the process requires drilling into the jawbone and takes many months for full osseointegration, where the bone fuses tightly to the implant.

Red light speeds up and improves this healing process so implants become fully functional faster. The light penetrates tissue to stimulate bone cells called osteoblasts, increasing local bone volume and density. Red light also boosts blood vessel growth to enhance oxygenation and nutrient delivery to the implant site.

In multiple trials, it was found that patients who received red light therapy after implant placement had faster postoperative wound healing, and the implants showed greater stability and success rates.

Relieve Orthodontic Pain and Discomfort

While orthodontic treatments like braces align the teeth, they often cause aching and tender gums and jaws. Rubbing the abrasive brackets and wires leaves gums inflamed and ulcerated. Opening too widely strains the jaw joint and muscles.

In multiple studies, it has been found that subjects who received red light therapy experienced accelerated tooth movement and significantly reduced pain compared with those in the control group.

Red Light Therapy Relieves Tooth Sensitivity

Dentinal hypersensitivity results when enamel erodes and exposes the underlying dentin. The open tubules of the dentin cause sharp pain when encountering hot, cold, or acidic foods and drinks.

Several studies have shown that red light therapy is effective in reducing dentin hypersensitivity. Just a few low-level laser treatments can provide lasting relief from hypersensitivity reactions.

Red light therapy Reducing Herpes Outbreaks

The herpes simplex virus-1 (HSV-1) causes periodic cold sore outbreaks in an estimated 67% of the global population under age 50. Unsightly and painful sores often erupt around the lips, nose, chin, and cheeks after common triggers like stress or sun exposure.

While antiviral medications can help control outbreaks, they come with side effects and may lead to viral resistance. Red light therapy is emerging as a promising alternative treatment.

A randomized, double-blind, placebo-controlled study found that exposing recurrent herpes simplex to red light significantly accelerated healing time and reduced the incidence of local recurrence of herpes simplex infection compared with no treatment.


If you struggle with gum recession, periodontal disease, canker sores, or other dental woes, red light therapy offers an easy, non-invasive solution. Clinical studies continue to validate its ability to reduce inflammation, accelerate healing, and fight bacteria for improved oral health. Experience how powerful yet soothing red light can be for your mouth. The benefits to your teeth, gums, and wellbeing are simply too great to miss out on!
