How Does LED Teeth Whitening Work? ›

LED lights whiten your teeth through their photochemical impact on the tooth surface. On application, the light energy activates the hydrogen peroxide in teeth whitening serum and speeds up the bleaching process.

First, the bleaching agent is applied to your teeth, and an LED light, laser, or halo light is then directed at your teeth. LED lights speed up the tooth-bleaching process by helping the peroxide to break down faster, forming free radicals that whiten the teeth.

Teeth whitening can make teeth whiter. The bleaching agent used for teeth whitening is peroxide which, in turn, breaks down the tooth enamel and makes it porous. This exposes the dentine below the enamel, and the bleaching agent penetrates deeper into the tooth's core to rebuild white tooth tissues from the inside out.

Is using light-activation worth it, though? Researchers found that laser, halogen, and LED light-activation produced increased lightening of tooth shade and maintained the lighter shade longer than non-light-activated teeth whitening in a study published in the Journal of Conservative Dentistry.

It is believed that most light sources decompose peroxide faster (by increasing the temperature) to form free radicals which whiten teeth.

At-home LED teeth-whitening kits may deliver results. But the whitening you see is a result of the gel, not the light. “There is not enough data to show definitively that the LED offers a significant improvement over just using a tray with the gel,” says cosmetic dentist Dr.

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.

laser teeth whitening is the safest, quickest, and most effective option among the types of teeth-whitening treatments available. However, there are ultimately several ways to whiten teeth, and the most suitable option will depend on your timeline, budget, and priorities, as well as the nature of the discoloration.

The treatment can get your teeth between 8 to 15 shades whiter. This is the benefit that you can get in just one treatment. Depending on the shade of your teeth and your aesthetic goals, you may need to get more than one treatment.

Baking-powder eliminates stains on the surface of your teeth and lemon juice as we already said has multiple components that lighten teeth. Just mix a teaspoon of baking powder and a teaspoon of freshly squeezed lemon juice and brush your teeth with the paste this mixture will work wonders in just two minutes.

Can you whiten your teeth with just the LED light? ›

Modern technology has actually made it possible to have a whiter and brighter smile quickly and easily. And, yes, the light does indeed play a role in the accelerated whitening process. However, simply smiling at an LED light will not whiten your teeth.

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.

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.

Research suggests that LED light therapy can help reduce and improve some skin conditions and issues. To see improvement in your skin, though, you need to have regular treatments. In-office LED light therapy uses more powerful strengths than at-home devices, which makes it more effective.

LED treatments can take more sessions and are less likely to cause tooth sensitivity, while laser tooth whitening is faster, more intense, likely to be completed in a single session, and more likely to cause tooth sensitivity.

In just 45 minutes, it's possible to whiten your teeth by up to 8 shades. In some cases, patients with severe stains may need to come back for multiple appointments at Carmel Mountain Dental Care.

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.

For 48 hours after a professional teeth whitening, it's recommended that you avoid acidic, pigmented foods and beverages and stick to things that won't cause discoloration. This is commonly called the “White Diet”, a short-term diet consisting of white and light-colored foods and drinks.
