How Long To Use Blue Light for Teeth Whitening

There are numerous whitening products and techniques available for those looking to achieve a brighter smile, whether it be at home or at a dentist’s office. These options range in effectiveness and price, with some being more affordable and convenient than others. However, it is important to note that none of these methods provide permanent results. While they can help to remove surface stains and improve the overall appearance of your teeth, regular maintenance and touch-ups may be necessary to maintain the desired level of whiteness. It is always best to consult with a dental professional before starting any whitening treatment to ensure it is safe and appropriate for your individual needs.

Blue LED light treatments are becoming increasingly popular, especially because they are considered safer than UV light. You can buy over-the-counter whitening products that include a blue light, or you can choose to have treatment in your dentist’s office.

You may be very pleased with the results, but you also might want to know what to expect with this treatment.

How Long To Use Blue Light for Teeth Whitening

Your dentist will apply a whitening gel to your teeth. Then they will use a blue LED light, which activates the hydrogen peroxide or carbamide peroxide whitening gel. This helps break apart the gel faster. The resulting chemical reaction lifts stains off your teeth.

Whether you’re at home or in your dentist’s office, the process works the same way.

One technique is a light-activated teeth whitening procedure. This treatment can use different kinds of lights, including:

  • ultraviolet (UV) lights
  • halogen lights
  • light-emitting diode (LED) lights

Does it work?

The research is mixed about the effectiveness of using a light source like an LED light to help whiten your teeth.

A 2014 studyTrusted Source reviewed a decade of research on light-activated sources for tooth bleaching in a dental office setting. It concluded that the use of a light activator did not seem to speed up the whitening process or improve the results.

However, a 2012 studyTrusted Source suggests that using a whitening gel and LED light as part of an in-office process did seem to be effective.

Blue Light Teeth Whitening Side Effects

Generally speaking, 2014 literature suggests that teeth whitening methods that use hydrogen or carbamide peroxide, including blue light whitening methods, are safe. This includes both clinical studies and in vitro studies, which are studies on teeth outside of a person’s mouth.

However, this treatment might have some risks. You may experience some tooth sensitivity and irritation in the areas of treatment after getting your teeth whitened with a blue light treatment method.

In one small 2012 study, an in-office treatment included an LED light to activate a whitening gel for three 10-minute cycles.

The study found that people experienced slightly more irritation and sensitivity around their teeth after that first in-office treatment than they did during a 2-week period of continuing treatment at home without the LED light.

Blue Light Teeth Whitening Before and After

If you choose to do a blue light teeth whitening procedure in a dentist’s office, here’s what to expect:

  1. Your dentist will thoroughly clean your teeth.
  2. They will take a shade measurement of your teeth to provide a comparison for the results of the whitening process.
  3. Your dentist will use tools like a cheek retractor to hold your lips away from your teeth and apply a gel to protect your gums.
  4. They will apply a whitening gel to your teeth.
  5. Your dentist will aim the blue light at your teeth.
  6. They will rinse your mouth completely and check the color of your teeth after the procedure.
  7. This process may be repeated a few times to improve the whitening results.

How to use blue light teeth whitening products at home

A blue light teeth whitening kit lets you whiten your teeth at home. One thing to consider: The at-home kits tend to contain solutions that are not as strong as the ones you get in your dentist’s office.

They may come with whitening strips containing the whitening agent or plastic trays that you fill with whitening gel, along with a battery-powered blue light.

The whitening kits generally work the same way:

  1. Apply the whitening product to your teeth. You will either place whitening strips directly on your teeth or insert whitening gel with a syringe into a set of trays. Insert the trays in your mouth to cover your teeth.
  2. You may need to let the whitening product sit on your teeth for a certain amount of time before turning on the blue light.
  3. Use the blue light to activate the whitening product. In some products, the light attaches directly to the mouthpiece, so you don’t have to hold it in place. In many products, the light will turn off automatically after a set amount of usage time.

Be sure to follow the exact directions on the kit that you’re using because they can vary from product to product. Some products advertise that you may need more than one treatment.

Where to Get a Blue Light Teeth Whitening Kit

About teeth whitening, the market is plenty of options right now. One widely utilized choice is a blue light teeth whitening kit, bought from specialty websites, big box stores, pharmaceutical stores, and other sites online. Usually consisting of a whitening gel applied to the teeth, these kits then expose the teeth to a blue light to help activate the whitening chemical and speed the whitening process.

When done in the comfort of your own home rather than a professional whitening visit, a blue light teeth whitening kit saves time and money. Many of these kits also contain simple instructions that let a wide spectrum of individuals access them, therefore enabling their simplicity of use.

For those with dietary restrictions or preferences, there are even kosher blue light teeth whitening kits, vegan, gluten-free ones. This ensures that folks with specific dietary demands may still have a nicer, whiter smile without compromising their medical needs or values.

Blue light teeth whitening products might not be suitable for everyone even if they might help to remove surface stains and brighten the teeth. Those with sensitive teeth or past dental problems should visit their dentist to be sure any whitening treatments are safe for their oral health before utilizing any.

In the end, blue light teeth whitening kits offer a convenient and readily available method to have a whiter smile straight from your own house. Since choices for those with dietary restrictions and preferences abound, everyone desiring to make their smile more radiant can find a kit out there.

Other types of light teeth whitening treatments

Blue light treatment is not the only light-based teeth whitening treatment available. Ask your dentist about these other treatments that they may offer in their offices.

Halogen light

Some research suggests that using a halogen light can help improve the results of a teeth whitening procedure. For example, one study published in 2016 found that using a halogen light with a 37.5-percent hydrogen peroxide solution whitened teeth better than going without the light.

However, this was an in vitro study, meaning it was done on teeth that were not in a person’s mouth. So the results might vary when performed in people. For now, if you’re interested, you may need to see a dentist to use this method.

Ultraviolet light

Your dentist may offer a procedure that uses an FDA-approved UV light or laser to help whiten your teeth. Although the potential risks of exposure to UV light seem low, they are still possible. Speak with your dentist about protection for your eyes and gum during the procedure.

Takeaway

Blue LED light teeth whitening products are one of several light-activated treatments available. The effectiveness of this type of treatment is currently mixed, according to research.

Ask your dentist for more information about using LED lights for teeth whitening.
