Red Light Therapy for Canker Sores - Relieve Pain

Introduction: Red Light Therapy for Canker Sores

Canker sores are small, painful ulcers that form within the mouth on soft tissues like the inner cheeks, lips, tongue, soft palate, or the gum base. These oral ulcers are very uncomfortable and become even more irritating when they hurt while talking, drinking, or eating. Though they appear like a small problem, the pain they generate is usually more severe than that of an ordinary ulcer.

Science is aware of this discomfort, and although many conventional mouth ulcer treatments, including canker sores, are available in the medical sphere, they never seem to be fully effective and take a considerable amount of time before bearing any visible results. Waiting for such sores to heal and tolerating difficulty in eating or drinking is far from desirable.

Fortunately, science has introduced a new, gentle, and safe method—red light therapy—which offers comfort and relief from canker sores. Red light therapy helps reduce inflammation and pain while stimulating cellular repair, allowing these ulcers to heal more quickly and making the healing process more tolerable.

In this article, we’ll explore how red light therapy for canker sores works, its benefits, and what scientific research reveals about its effectiveness.

Understanding Canker Sores: Causes and Triggers

Canker sores, or aphthous ulcers, are small, shallow, and painful ulcers that occur within the mouth on soft tissue like the inside of the cheeks, lips, tongue, soft palate, or at the base of the gums. The sores are not contagious, but they can be quite painful. They typically have a white or yellow spot in the center, surrounded by a red border.

Even to mention the words "canker sores" is uncomfortable because these mouth ulcers are far more painful than regular ulcers. There are various forms of canker sores:

• Minor canker sores: The most common type, small (less than 1 cm) and oval-shaped with a red border, typically heal in 1 to 2 weeks without scarring.

• Large canker sores: Larger, deeper, and more tender. They heal within 6 weeks and often leave scars.

• Herpetiform canker sores: Rare, with small clusters of small sores that sometimes coalesce into large ulcers. They can heal within several weeks but rarely leave scars.

No one knows the exact cause of canker sores. But many causes are suspected to develop them, among them stress and tiredness, minor trauma to the mouth due to overbrushing, dentistry, or accidental bites, food allergies like citrus fruits, spicy foods, or chocolate, vitamin deficiencies (particularly B12, iron, and folate), hormonal changes, medical conditions such as celiac disease or inflammatory bowel disease, and immunosuppression. Occasionally, individuals have a predisposition to the formation of canker sores due to genetic factors.

They are prevalent, and various individuals develop them for various reasons. They tend to result in discomfort while eating, drinking, or speaking because of the pain.

Challenges with Traditional Canker Sore Treatments

Canker sores can be painful and may take weeks to heal. There are numerous conventional treatments for these painful mouth ulcers in stores today, but rather than offering a final solution, they merely give temporary relief. It's similar to applying a cream that calms your condition for some time, only to have the pain return.

This is true for conventional canker sore treatments—they work briefly to decrease pain and swelling, but cannot help keep sores from recurring. Because the cause of canker sores is unknown, recurrence is highly likely, and these treatments also require time to heal the damaged mouth tissue.

Over-the-counter pain relievers, mouthwashes, and topical gels are some of the common folk remedies. It is difficult for younger patients to use these topical gels and rinses frequently. Additionally, individuals with sensitive mouths may experience allergic reactions, dryness, or irritation from certain medications or mouthwashes.

These remedies are not capable of treating the cause of canker sores because they only treat the ulcers that are already formed within the mouth.

How Red Light Therapy Supports Healing and Pain Relief

The Science Behind Red Light Therapy for Oral Tissue Repair

Red light therapy is a non-invasive and holistic method that utilizes different wavelengths of red and near-infrared light to penetrate the skin and stimulate the body's natural healing processes. The wavelengths are harmless and do not cause damage similar to UV radiation. When applied to oral tissues affected with canker sores, the light penetrates soft tissues and skin, stimulating cellular repair and regeneration.

On the cellular level, red light therapy enhances the energy production in the form of ATP (adenosine triphosphate). This extra energy reflects cells having enough power to deliver repair functions with high efficiency. Red light therapy stimulates the mitochondria, the cells' energy-producing factories, to enhance ATP production. In doing this, red light therapy promotes healing of damaged cells more quickly and can also be a respite for underlying conditions like inflammatory bowel disease (IBD) that can cause canker sores.

Red light therapy also increases blood flow to the target area, allowing cells to receive increased oxygen and nutrients, which in turn speeds up the healing process. Elevated circulation also aids in the elimination of toxins from the injured tissues.

Red light therapy is also crucial in pain relief and inflammation, two of the most painful symptoms of canker sores. It reduces inflammation by inhibiting the release of pro-inflammatory cytokines and diminishes pain by inducing the release of endorphins, the body's natural painkillers. This indicates red light therapy not only provides relief and comfort from symptoms but also hastens the healing of the damaged skin caused by canker sores.

Does Red Light Therapy Work for Canker Sores? What Research Says

Red light therapy is becoming popular as an effective remedy for canker sores because it has the ability to reduce pain, swelling, and stimulate healing. Does it work? Scientific research indicates promising results. Clinical studies on the red light treatment of canker sores have shown that treated patients experience less pain and heal faster than those who receive standard treatments, with minimal relief and frequent recurrence within a few days. It has been reported in research that red light therapy improves cell healing, reduces inflammation, and increases blood flow to the injured tissues—all vital features that help boost the healing of oral ulcers.

Clinical Studies on Red Light Therapy for Oral Lesions

Study 1: Effectiveness of Red Light Therapy in Relieving Pain and Healing Canker Sores.

Objective

The aim of this study was to determine the effectiveness of Low-Level Laser Therapy (LLLT), also known as red light therapy, in treating canker sores. More specifically, it investigated whether LLLT reduces pain, shrinks the sores, and accelerates their healing, compared to receiving no treatment at all.

Result

The results were that the patients who received red light therapy recovered much faster. Their canker sores healed in 3 days while the control group took almost 9 days to heal. Further, within the first time point immediately after treatment, nearly all patients (28 of 30) claimed their pain was completely gone.

Conclusion

Red light therapy proved very beneficial in alleviating pain and speeding up the healing process of canker sores. It is safe and effective for those seeking rapid relief from a painful condition.

Study 2: Rapid Pain Relief and Healing of Canker Sores Using Diode Laser Therapy.

Objective

To determine the efficiency of Low-Level Laser Therapy (LLLT) with the use of a diode laser in alleviating pain and healing recurrent aphthous ulcers (canker sores) in the mouth.

Result

A 30-year-old female with recurrent painful mouth ulcers on the lower lip and tongue was treated with a diode laser 915 nm. She was relieved of pain immediately following the application of the laser, and the ulcers completely healed within 5 days with no discomfort or complications.

Conclusion

Diode laser therapy may be a useful and safe treatment option for aphthous ulcers. Diode laser therapy relieves pain immediately and heals faster than traditional treatments.
