In a world of selfies and video conferencing, we all want our smiles to look our best. Not only does it look great, but a healthy smile relates to overall health, too. Excellent oral hygiene includes a combination of regular dentist visits and a good dental hygiene routine at home. Thanks to newer technology, there are over-the-counter alternatives that you can add to your dental cleaning regimen, including LED red light therapy for teeth and gums. 

Light therapy is known in the beauty world first and foremost for treating skin conditions. Red and infrared light primarily treat wrinkles and conditions related to inflammation, while blue light treats acne. Many people also rely on LED light technology for pain relief purposes, but if you have never explored it for oral health, now is the time to learn more about what it can do for you. 

Why Is Oral Health Important to Enjoy a Healthy Life?

Yes, we all want smiles worth a million bucks, but good oral health will dictate a lot about the rest of your health. According to the Mayo Clinic, conditions like cardiovascular diseases, pneumonia, and pregnancy or birth complications can be associated with poor oral health. Plus, a healthy mouth is essential to prevent other problems like bad breath, tooth decay, and gum disease. The importance of oral health shouldn’t go unnoticed if you want to enjoy a long, healthy life with great teeth. After all, there is no turning back to fixing them once they start to decay.

Using Red Light Therapy for Oral Hygiene

Since our early years of life we are taught that brushing and flossing are enough for good oral health. There are bad bacteria that can only be found in our mouths. As shocking as this sounds, there is no need to worry if you follow a proper oral hygiene routine. Besides regular cleaning, a few minutes of light therapy daily will help prevent gum disease, relieve pain, help whiten teeth, and combat oral microbes and bacteria that cause bad breath.

Red light therapy works by increasing circulation and speeding cell turnover. In the same way that it can improve the health of skin cells to reduce dark spots and wrinkles, it can improve the health of the gums, and reduce pain from things like cold sores.

Blue Light Therapy for Teeth Whitening

In addition to the red light, oral care devices may also have non-UV blue lights that will increase the effectiveness of whitening products. Even if you care for your teeth perfectly, things like coffee and red wine stain the enamel and the underlying dentin with time. 

When you use a bleaching product on your teeth, a chemical reaction opens the pores of the teeth and lifts out the discoloration. Blue light, in the range of 450 to 500 nanometers, speeds up that chemical reaction. After a professional tooth whitening in a dentist’s office, you can help maintain your results by using an oral care light therapy device at home. A study published in the Open Dentistry Journal said that blue LED lights were more effective at whitening compared with other types of light—lasers and plasma arc lamps—sometimes used in clinical settings. 

About the dpl® Oral Care Device

The dpl® Oral Care device uses infrared and red light to treat all the things mentioned above. Also, it’s super easy to use: 10 to 20 minutes per treatment is all you need to use this light therapy device, depending on your goal. For gum health, the recommended frequency is once a day for 10 minutes. If your goal is teeth whitening, then aim for two to three treatments a week for 20 minutes each.

Is LED Light Therapy Safe to Use on Your Teeth and Gums?

It is normal to associate the color red with something negative or dangerous, but red light therapy, as well as blue light therapy, are safe to use in your mouth. Dentistry journals have long written about the benefits of light to treat periodontal pathogens and whiten teeth. Now LED technology is available for home use. The blue LEDs in the dpl® Oral Care use non-UV wavelengths of light, so there is no danger from UV radiation. As with anything, use your dpl® device as instructed for safety and consult with a professional hygienist or dentist before starting a whitening or oral care regimen.
