Does red light therapy help with sensitive teeth?

If you cringe every time something cold touches your teeth, or find yourself avoiding certain foods because they make your mouth ache, you’re not alone. Sensitive teeth is an extremely common problem that affects millions of people. While there are some conventional treatment options available like special toothpastes or dental work, these can be costly and not always effective. That’s why more and more people are turning to natural solutions like red light therapy to help manage tooth sensitivity.

Does red light therapy help with sensitive teeth?

In this comprehensive guide, we’ll explain what causes sensitive teeth, and why red light therapy is an effective remedy. We’ll also provide tips on making other lifestyle changes to support your sensitive teeth treatment. By the end, you’ll have all the information you need to decide if red light therapy could be the solution you’ve been searching for!

What is Tooth Sensitivity?

Tooth sensitivity, also called dentin hypersensitivity, is characterized by sharp pains when substances come in contact with your teeth. This can be triggered by hot or cold temperatures, sugary or acidic foods, aggressive brushing, and even exposure to air. The pains are typically sharp and sudden, but go away once the trigger is removed. They can range from mild irritation to severe discomfort that makes eating challenging.

While anyone can develop sensitive teeth, it’s more common if you have:

  • Gum recession exposing more of the tooth root
  • Worn down enamel from grinding or acid erosion
  • Cracked or chipped teeth
  • New dental work like fillings, crowns, or whitening treatments
  • Increased brushing pressure combined with abrasive toothpaste

The main cause relates to dentin exposure. Dentin is the tissue underneath the enamel that surrounds the inner nerve. When the protective enamel layer gets thinner or gum line recedes, the dentin becomes more exposed and susceptible to external stimuli.

Causes of Tooth Sensitivity

Before exploring how red light can help, it’s important to understand what makes teeth sensitive in the first place. There are a few key culprits:

  • Exposed Dentin: Underneath the protective enamel outer layer of your teeth is a softer, porous tissue called dentin. When the enamel erodes due to factors like acid erosion, gum disease, or aggressive brushing, the sensitive dentin underneath gets exposed. This allows hot/cold stimuli to penetrate through the pores and reach the inner tooth nerves, causing discomfort.
  • Damaged Tooth Roots: Cracks or exposed areas on the tooth roots can also cause sensitivity. The roots do not have a protective enamel layer like the crown of the tooth.
  • Gum Recession: When your gums recede due to periodontal disease, more of the tooth and roots get uncovered. This exposes more dentin and increases sensitivity.
  • Dental Procedures: Certain dental treatments like crowns, fillings, or professional cleanings can cause temporary sensitivity by irritating the inner tooth nerves.

As you can see, most tooth sensitivity stems from enamel wear and gum recession. The good news is red light therapy works to heal and strengthen enamel, reducing sensitivity at the source.
As you can see, most sensitivity comes down to the inner parts of your teeth becoming overexposed. The problem then arises when hot/cold foods, air, brushing, etc make contact and cause discomfort.

What is Tooth Sensitivity?

How Does Red Light therapy Help Sensitive Teeth?

Red light and near-infrared light therapies utilize wavelengths of natural light to deliver healing photobiomodulation to cells and tissues. These therapeutic wavelengths can penetrate deeply and trigger beneficial responses at the cellular level.

So how exactly does shining red light on your gums help reduce tooth discomfort? The non-invasive light has been shown to provide the following benefits:

Specifically for sensitive teeth, red/near-infrared light works in two main ways:

1. Accelerates Remineralization

The dentin layer under your enamel contains most of your tooth’s minerals like calcium and phosphate. When the enamel erodes, these get depleted, making teeth more porous and sensitive. Red and near-infrared light energizes cells called odontoblasts that are responsible for producing new dentin and pumping minerals back into it. This remineralization makes the dentin layer dense again, closes off the pores, and decreases sensitivity.

2. Reduces Inflammation and Nerve Pain

The light wavelengths also have anti-inflammatory and analgesic effects that provide pain relief. They can calm irritated nerves and inflammation in the pulp of your tooth that get aggravated by hot/cold stimuli. This provides temporary numbness and sensitivity relief.

Additionally, by killing bacteria that cause gum disease, red light can help prevent receding gums and exposed roots that contribute to sensitivity. Overall, it addresses multiple causes for reducing tooth discomfort.

3. Increases Blood Flow

By boosting circulation and oxygen delivery, red light supports faster healing, pain relief, and nerve repair. More blood flow also disrupts the buildup of inflammatory compounds causing discomfort.

4. Kills Bacteria

Red light is a natural disinfectant and shown effective at neutralizing oral bacteria involved in decay, infection, and inflammation. This provides a cleaner, healthier environment for nerves.

5. Accelerates Cell Turnover

The light stimulates faster turnover of gum, bone, and other tissue cells. This helps regenerate healthier structures around the teeth for protecting dentin and nerve endings.

As you can see, red light provides multiple benefits for not just managing sensitivity symptoms, but optimizing the local tissue and nerve environment for long-term improvements.

How Does Red Light therapy Help Sensitive Teeth?

Red Light Therapy Used in Tooth Sensitivity Study

But does the existing research back up these promising benefits of red light therapy for dental health? Let’s examine some key scientific studies:

A 2022 retrospective study showed that red light therapy was the most effective at reducing tooth sensitivity compared with other treatments.

A 2019 meta-analysis found that red light therapy combined with fluoride treatment had the best results in reducing tooth sensitivity.

In a 2016 randomized clinical trial study, it was found that the group receiving red light treatment had significantly less tooth sensitivity than the control group.

Advantages Compared to Traditional Tooth Sensitivity Treatment

Standard treatments for tooth sensitivity include things like prescription strength toothpaste, mouthwashes, bonding, and nerve blocks. But these tend to only provide temporary numbing or surface protection. The advantages of using red light therapy instead include:

Addresses Underlying Causes – The light targets inflammation, promotes healing of gum and enamel damage, desensitizes nerves, and kills bacteria for lasting improvements. Toothpastes just numb the area temporarily.

Non-Toxic and Natural – It’s a safe, chemical-free therapy using beneficial wavelengths of natural light. No concerns with side effects, addiction, or developing antibiotic resistance in bacteria.

Works Quickly – You can start experiencing pain relief after just a few brief treatments. Traditional methods take weeks or months to start working (if they work at all).

Convenient At-Home Use – Light devices are easy to use anywhere. No need to book appointments or even leave your house. Provides on-demand pain relief.

Improves Overall Dental Health – Along with minimizing sensitivity, the light has positive effects on gum health, tooth decay, breath, smile aesthetics, and more.

No Habit Formation – It works to permanently desensitize teeth without forming dependency or tolerance like pharmaceuticals. The results last long-term.

How To Use Red Light Therapy on Teeth Effectively?

To get the best results from red light for sensitive teeth, be sure to follow proper use guidelines:

  • Protect Eyes: Always wear included safety glasses to shield your eyes from light exposure during treatments. Long-term eye damage can occur otherwise.
  • Clean Devices: Disinfect mouthpieces and intraoral wands after each use to prevent bacterial spread. Follow all manufacturer cleaning instructions.
  • Shine Light Inside Cheeks:Angle light toward the interior cheeks and gums to reach more surface area. Rotate your jaw to expose all sides.
  • Position Light Over Full Mouth Area: For panels, be sure to move your head to bathe all areas of the open mouth in red light.
  • Follow Recommended Time: Most devices suggest 10-20 minute sessions. Stick to the guidelines for best sensitivity relief.
  • Repeat Daily: Use red light therapy on teeth 1-2 times per day for lasting results and prevention. Consistency is key.

Targeting your inner cheek tissue, gums, and all tooth surfaces with regular red light can significantly improve dental comfort and health over time.

Lifestyle Tips to Support Your Sensitivity Treatment

While red light therapy delivers results on its own, you can speed up progress and minimize symptoms faster by combining it with healthy oral care habits:

  • Brush gently: Aggressive brushing erodes enamel. Use a soft bristle brush and gentle motions.
  • Avoid abrasives: Skip whitening toothpastes and mouthwashes with alcohol that can strip enamel.
  • Drink water: Stay hydrated and rinse with water after eating/drinking to neutralize acids.
  • Limit acidic foods: Citrus, vinegar, carbonated beverages, etc can degrade enamel.
  • Get fluoride: Use toothpaste/rinses with fluoride to strengthen enamel.
  • Chew xylitol gum: Xylitol prevents bacteria growth that causes cavities and gum disease.
  • Monitor medications: Some prescriptions like antihistamines reduce saliva flow, allowing more acid.
  • Get preventive dental care: Regular cleanings and checkups monitor sensitivity causes.

Following these tips along with red light therapy helps create an oral environment that fights sensitivity while promoting mineralization and healing.



Combined with minor lifestyle adjustments, red light therapy offers an effective solution to boost your oral health and make sensitive teeth a thing of the past! Get started today to stop avoiding your favorite foods and drinks. Red light therapy provides a safe, natural solution to sensitivity discomfort for better dental health and quality of life long-term.
