What Causes Gum Recession?

Gum recession is a type of gum disease. It causes your gum tissue to recede and pull away from your teeth, exposing the roots underneath. Receding gums can lead to serious dental problems. Unfortunately, some causes of gum recession are beyond your control.

Here are the most common causes of gum recession.

1. Genetics

Some people are born with gums that are prone to receding. Even if you practice good oral hygiene, you may deal with gum recession if it runs in your family.

2. Aggressive Brushing

Some items become cleaner the more aggressively you scrub them, but it is not the same with your teeth. Overzealous brushing damages the teeth's enamel and wears away the gum tissue.

3. Mouth Trauma

Physical mouth trauma causes your teeth to become loose or fall out. You can get mouth trauma from a blow to the mouth, aggressive brushing, or a fall that hits your face. Ornamental piercing on the tongue or the lips can also cause trauma to the gums due to frequent friction.

4. Periodontal Disease

Gingivitis is a gum disease that leads to red, swollen gums in the early stages. If ignored, gingivitis can progress to periodontitis, which involves the buildup of bacteria, infection, inflammation, and gum tissue damage, leading to recession.

5. Orthodontic Therapy

Orthodontic therapy is an excellent way to straighten teeth and improve oral health. However, the constant force of braces, invisible aligners, or spreaders that reposition your teeth can lead to receding gums due to inflammation.

6. High Frenal Attachment

Frenal is the membrane connecting the gum and the muscles that move your lips and cheeks. If yours are attached too high, every lip and cheek movement you make tugs and pulls at your gum, causing a recession in the long run.

7. Teeth Grinding

Teeth grinding exerts force on your jaws, irritating and damaging the gum tissue. It often occurs at night, and most of its victims are unaware of it. The condition is known as bruxism. The first warning signs of bruxism are receding gums, headaches, and worn teeth.

8. Poor Oral Hygiene

Dental hygiene is essential for good breath and good dental health. If you don't brush and floss your mouth correctly, oral bacteria build up on your teeth, causing plaque. Over time, plaque turns into calculus or tartar, which is more difficult to remove.

When tartar gets under your gum, it separates it from your teeth, causing gum recession.

9. Smoking And Chewing Tobacco

Tobacco smoking or chewing causes bad breath and is a poor oral habit. It is also related to other health issues, including cancer and heart attack. Tobacco use in oral health leads to discoloration as well as receding gums and periodontal disease.

Is Red Light Therapy Effective for Gum Regeneration?

The short answer is yes! The treatment utilizes red and near-infrared light to set in motion energy production in cells. Wavelengths of red light boost cellular functions that promote cell rejuvenation and faster healing.

Red light therapy is effective for gum regeneration in the following ways:

1. Increases Adenosine Triphosphate production (ATP)

Adequate ATP improves cell health, increases blood circulation, reduces inflammation, and encourages faster tissue healing. using red light therapy for oral hygiene, these actions promote gum regeneration.

2. Increases Collagen Production

Collagen increases elastin and reduces soreness. It reverses the aging process of tissue.

3. Increases Blood Circulation

Increased blood flow means more nutrients and oxygen supply in the treatment area. It also helps discard toxic waste from damaged tissue, thus promoting healing.

4. Wound Healing

Red light wavelengths help the wound heal better. They also stimulate the growth of new tissue and blood vessel networks, making red light therapy effective for gum regeneration.

Benefits of Red Light Therapy for Gum Health

Photobiomodulation exerts temporary mild oxidative stress on the mitochondria. It makes the cells stronger and activates their defense systems. Due to this anti-inflammatory and antioxidant response, the mitochondria increase energy efficiency, making them more capable of producing adenosine triphosphate (ATP).

By using these wavelengths of light on different areas within the body, RLT can help reduce pain and accelerate healing time. Low-level light therapy is effective on damaged tissue, blood vessels, tendons, and nerves. In dentistry, the benefits of red light therapy for gum health include:

1. Periodontal Treatment

Phototherapy, mainly blue light therapy, can kill periodontal pathogens like Aggregatibacter actinomycetemcomitans and other types of bacteria. Red light also has antibacterial properties.

In one study, researchers found that red light therapy encouraged beneficial processes in gingival fibroblasts or gum tissue cells. Wavelengths of red and NIR reduced oxidative stress and inflammation and decreased cell death.

2. Promote bone, gum, and Tooth regeneration

Regular and consistent use of red light therapy for oral health stimulates cell growth that helps treat the degeneration of jaw bones, teeth, and gums.

A published study in Nature (2022) shows that deep absorption of near-infrared light into bone tissue can promote bone regeneration. As mentioned earlier, mouth trauma resulting in jaw weakening can contribute to receding gums.

Another study shows a significant increase in cell growth due to ATP production. More energy increases mitochondrial metabolic activity and the production of nitric oxide, a vasodilator. During the treatment, there was evidence of increased teeth remineralization.

3. Treatment of bacteria

Poor oral care contributes to gum disease. Plaques form due to the remaining food particles, mucus, and bacteria on the teeth. Plaque can cause inflammation, tenderness, and swelling of the gums, leading to bleeding during brushing and flossing. This stage is called gingivitis and has symptoms of bad breath.

When untreated, gingivitis leads to periodontitis, which is more serious. Periodontal disease manifests as tooth decay, tooth loss, and bone deterioration. The build-up of plaque on teeth and along the gum line enables bacteria to penetrate below the gums, causing inflammation in the gum tissue.

Red light therapy boosts the mitochondria by producing the energy necessary for healing. It also stimulates the cells that produce collagen, an essential component for healthy gums.

Using red light therapy can help you treat periodontal disease. Red treatment promotes gum health and healing by reducing tissue degradation, killing harmful bacteria, and acting as an anti-inflammation. It also boosts collagen production, which helps you regrow healthy gums.

4. Reducing Teeth sensitivity

Teeth sensitivity due to rapid temperature changes when eating or drinking is not a comfortable and not a good sign. You may start experiencing teeth sensitivity because receding gums expose the root's surface.

According to 23 studies involving 946 participants with unexplained tooth pain unrelated to periodontal disease, Red light therapy for gums can reduce tooth sensitivity without side effects.

According to a 2021 review, red light therapy has immediate and long-term pain reduction benefits.

5. Accelerates healing of dental work

Many dental procedures result in sore gums and soft tissue. Because of its analgesic and stimulating effects on human tissue, RLT helps to reduce postoperative pain and support wound healing after dental surgery or tooth extraction. It also helps remove plaque and tartar after deep cleaning, which is called tooth scaling and root planing.

Red light therapy for gums also accelerates healing in people with dental implants. Dental implant success depends on how well the tooth bonds to the gum tissue. Implant failure is often a result of inflammation and infection of the gum and supporting bone.

6. Red light is Non-invasive and Convenient.

Red light therapy is non-invasive, chemical-free, and painless. So you can incorporate the treatment into your daily routine without downtime. You can complement your oral health routines with red light therapy in the convenience of your home.

Using Red Light Therapy as a Complement to Traditional Dental Treatments

Preventing gum issues, including periodontal disease, starts with maintaining a healthy lifestyle, good oral hygiene, and regular checkups with a dental professional. You should know that red light therapy cannot replace traditional oral hygiene routines and treatments for various gum issues.

You must use red light therapy to complement traditional dental treatments and oral hygiene routines. These include:

● Brush twice daily for at least 2 – 4 minutes

● Floss daily

● Use recommended mouthwash

● Go for dental checkups and cleanings at your dentist and hygienist's office twice a year.

● Quit smoking or chewing tobacco

● Maintain a balanced diet rich in nutrients

● Stay hydrated

● Correct misaligned teeth

● Take care of fillings, crowns, and caps

1. Teeth Whitening

Discoloration and teeth stains prevent many people from achieving a perfect smile. Most seek teeth whitening procedures to enhance a brighter smile—red light therapy as a complement to traditional teeth whitening treatments.

Regular use of red light therapy helps maintain results from teeth whitening procedures, reducing the need for frequent treatments.

2. Red Light Therapy as a Complementing Traditional Dental Procedures

This may be where red light therapy for gums is most beneficial. Traditional dental procedures like tooth extraction, implant, or surgery leave you with soft tissue on your gums. Red light therapy helps faster recovery tissue regeneration and reduces postoperative pain.

How to Use a Red Light Therapy Panel for Gum Care

Although red light therapy has many benefits for gum health, we recommend consulting your healthcare provider before trying a new treatment. Light therapy may affect you negatively if you have sensitive skin or an underlying health condition.

When seeking an LED light therapy device for at-home use, ensure it's FDA-certified for medical purposes. Look for a versatile device like the Redlitex Mini. You can use the equipment to treat different areas of your body and for various issues.
