What’s the best LED teeth whitening kit? Whiten your teeth affordably from home.

There are many ways to bleach teeth by yourself, but LED teeth whitening kits are getting more and more attention. How do they differ and how to choose the best one for you?

It’s not easy to find the best teeth whitener. Upon first glance, you could say that all whitening kits are the same. When you look deeper, however, you can see some differences.

The kits stand out when it comes to application methods, active ingredients in the serums, the contents of the sets, and the prices. The good news is that they are a lot cheaper than in-office whitening, even though they may work slower.

Dr. Eric Moryoussef
A product with 30% carbamide peroxide is equivalent to 10% hydrogen peroxide. Studies have shown that both products work equally well, despite their differences.

What you choose depends mainly on how quickly you will see results and how long you will be able to enjoy the effects. Below you can read about the 7 best teeth whitening kits. Let’s get started!

How does LED light work to whiten teeth?

An LED (light-emitting diode) is a bulb that gives out a very particular kind of light, typically blue or red. It doesn’t produce a lot of heat and it is not harmful either, like UV rays are.

Teeth are whitened by the active ingredients (usually carbamide peroxide or hydrogen peroxide) in the gel or serum. The LED is claimed to speed up the process by helping the product break down.

Dr. Eric Moryoussef
The whitening gel is activated when its hydrogen peroxide or carbamide is broken down. This allows the ingredients to destroy stain molecules.

Generally, research shows mixed results when it comes to the effectiveness of LED light in whitening teeth.

Pros

  • acts as a catalyst in whitening treatment
  • doesn’t produce heat, so you don’t feel any pain
  • delivers relatively fast results
  • convenient, as it doesn’t need a warm-up period
  • not found to be cancerous or otherwise harmful

Cons

  • some patients have reported sensitivity after whitening treatment
  • can dehydrate the teeth if used for a long period of time

Are LED teeth whitening kits safe?

Teeth whitening kits with LED light are generally safe, and even recommended by many dentists. There might be side effects, though, such as:

  • gum irritation,
  • tooth sensitivity,
  • demineralization of teeth, and
  • tooth erosion.

But those are probable when patients do not use the kits as they were intended. Below are some general guidelines you should keep in mind when bleaching teeth from home.

Do's

  • consult with your dentist beforehand
  • visit the dental office for routine check-ups and cleanings
  • treat your gum disease and fill your cavities before whitening
  • adhere to instructions on the packaging closely

Don’ts

  • use the kit longer than stated in the instructions
  • treat your teeth with expired products
  • swallow large amounts of the serum

Most companies claim that their products are suitable for those with dental work. Always consult with a dentist before using OTC products, even if it’s not suggested by the brand, though.

Dr. Matthew Stewart
While OTC kits may be safe to use with crowns, veneer, and so on, it should be noted that these will not be whitened or changed. Only natural teeth will become more white.

Only a dental professional can accurately assess whether your teeth and gums are in the right state for whitening. He or she might also suggest which concentration or type of treatment would be best for you.

FAQ

Are teeth whitening kits effective?

Yes, they are. The serums which make up the key part of every kit typically contain peroxide or carbamide peroxide. Those are bleaching agents which actively alter the color of the teeth.

Additionally, LED lamps help them break down, which makes them work faster.

How long do the effects of teeth whitening last?

Teeth whitening effects are visible for different periods depending mostly on your lifestyle. If you are a smoker or drink a lot of wine, tea, or coffee, the results will not be visible as long.

Dentition is usually whiter for a few months after treatment.

Are there side effects to teeth whitening?

The most common side effect of whitening teeth is temporary sensitivity. Some brands claim that their product should not cause it, though.

Adhere to the product instructions closely, and there should be no lasting damage to your dentition.

Can I use LED whitening kits with sensitive teeth?

If your teeth are generally sensitive it is best practice to check the product description. Each brand has different recommendations as to their effect on sensitive teeth.

Stop the treatment for a few days or consult with your dentist whether there are any contraindications to you using the kit if you do experience some discomfort.

Can I eat and drink normally when whitening my teeth?

It’s good practice to avoid foods and drinks that easily stain the teeth to make your smile brighter for longer. Most companies recommend abstaining from eating and drinking for at least 30 minutes after you use the product.

The best time to perform the treatment is therefore just before going to bed.
