How Does LED Teeth Whitening Work? Is it safe and effective? ›

To break it down simply, the lights heat up the gel's peroxide and act as an accelerator. In theory, the light helps the gel break up more stains faster. Several LED teeth-whitening kits make these claims, with some even saying their devices are similar to dentist-office whitening.

LED teeth whitening is a new and impressive way to achieve brighter teeth. It uses LED lights to activate the whitening solution, resulting in whiter teeth in a shorter amount of time. Moreover, it is safe, fast, and convenient – perfect for those who want quick and visible results.

It's generally safe to use an LED teeth whitener once every 24-48 hours, depending on the strength of the device and the sensitivity of your teeth. The MOON Teeth Whitening Device is designed to be gentle and is safe to use twice a day for 14 days at a time.

The LED teeth whitening light is safe to use as directed and helps the ingredients in Crest 3DWhitestrips work more effectively by safely penetrating the enamel surface to weaken tough, yellow stains.

Most people will see a noticeable difference after just one treatment, but for more severe cases, you may need up to four treatments. It's important to note that LED teeth whitening is not a permanent solution, so you'll likely need to repeat the treatment every few months to maintain your results.

Whitening gels are normally made with either hydrogen or carbamide peroxide. LED-powered devices are another popular choice. They work by using the peroxide gel as a base and activating the gel. The LED works to speed up the gel's effects, accelerating the process and enhancing results through an oxidation process1.

Blue light itself cannot whiten the teeth. Instead, blue light is used to activate a chemical reaction. You'll apply a specialized whitening gel to the patient's teeth containing either carbamide peroxide or hydrogen peroxide. The blue light activates the compounds in the gel and helps break it apart faster.

As for whether you should brush your teeth after using whitening strips, there is no definitive answer. While some experts recommend brushing immediately after removing the strips to ensure all residue is removed, others advise waiting for 30 minutes to allow the enamel to rehydrate and minimize potential abrasion.

While beverages and liquids such as milk and water are okay to drink, dark-colored beverages should be avoided after a teeth whitening procedure. Avoid beverages such as coffee, dark sodas, red wines, and tea. You should also avoid dark juices including cranberry, grape, orange, and tomato juice.

Although results cannot be achieved with an LED light alone, phenomenal results are produced when used with whitening gels.

Does baking soda whiten teeth? ›

Baking soda can be used with some water to remove the stains on the surface of the teeth. It can also be used with hydrogen peroxide to enhance its whitening effects. Baking soda can be used by individuals with regular toothpastes too. It is also used commercially in some teeth whitening products and toothpastes.

Though some lights can add a temporary boost that fades within a day or so, none ultimately make your teeth whiter than trays of bleach or whitening strips alone. Nor can they shorten the amount of time you have to spend with a mouth full of whitening chemicals to achieve your desired tooth shade.

One of the most significant benefits is its safety compared to UV light. While UV light teeth whitening has been linked to cancer and other health problems, blue LED light is considered safe and has minimal side effects.

Similar to blue light whitening, LED teeth whitening can be done every 1-2 weeks.

Firstly, whitening time is shorter for only 2-3 minutes, much less than 30-45 minutes of LED light bleaching. Secondly, there is lower teeth sensitivity, while LED light whitening has a strong acid swelling reaction. Thirdly, laser tooth whitening has a better effect and can last for longer time.

Classic at-home whitening strips are a great place to start, but teeth whitening kits that utilize the power of LED light might be even better. “While LED technology does not directly whiten your teeth, it helps to speed up the whitening process when using an at-home kit,” says bicoastal cosmetic dentist Dr.

You can safely whiten your teeth with blue light every 1-2 weeks, depending on your sensitivity and desired results. It's important to follow product guidelines to avoid overuse.

Conclusion: Both tooth whitening methods had a significant whitening effect after 15 days of use. However, the onset of whitening was significantly faster when using the nonabrasive, activator-containing toothpaste combined with an LED device. The toothpaste and LED device were both safe.
