Buying guide – Best teeth whitening light

What are teeth whitening lights?

Teeth whitening lights or LED teeth whitening kits are a very effective way of ridding your teeth of all the dirty stains that they develop over time. And these lights are constantly gaining popularity among people because of their impressive results.

Parts in a teeth whitening light kit

There are two different parts in a teeth whitening kit. First, are the trays, that are kept in your mouth and they sort of wrap around your teeth. The second major component is the LED light that lightens your teeth. Let’s dig a little deeper into them.

  • Tray

The first part of the kit, the tray, is small in size and is made of soft material. The tray is accompanied by a teeth whitening gel that is filled inside the tray and then the tray is put inside your mouth. The gel used in these kits is generally carbamide peroxide, which is known to lighten your teeth.

The trays are carefully designed to snugly fit into your mouth without feeling uncomfortable. Generally, there are different trays for upper and lower teeth, because of their different shapes.

There are some teeth whitening lights that also come with paint-on gel instead of trays. The gel is directly applied to the teeth and then they are faced with the light for the required treatment time.

  • LED Lights

The other prime component is the LED light itself, which bleaches your teeth. It doesn’t exactly whiten the teeth itself but quickens the gel’s effect. You would also have heard of this light with the name of LED bleaching light.

These lights are quite powerful and penetrating, which is why they deliver such phenomenal results. How these lights work is simple. They enforce the gel’s bleaching ability on your teeth’s surface, which results in lightening your teeth.

However, you need to bear in mind that the intensity of the light differs from one kit to another. Some kits deliver strong enough light to make your teeth many tones lighter in just a single prolonged sitting. On the other hand, some kits require several numbers of sessions to give you that kind of whiteness.

The advantage of a more intense light is that you can use it on an urgent basis, due to its quick deliverance of results. However, if you are prone to tooth sensitivity, you should opt for a light that works slowly but efficiently.

Also, while purchasing your kit, make sure that the package contains the batteries for your light.

Things to keep in mind

  • Session planning

Instead of randomly starting your whitening session, you should properly plan it ahead. The purpose of planning is to ensure that you have got plenty of time to finish the procedure without anyone’s interruption.

The recommended treatment time in these lights also varies from one model to the other one. The suggested time for most of these lights is generally up to 20 minutes for a single treatment.  On the other hand, some recommend a time of 15 minutes for a single sitting.

The suggested time duration should be followed accurately. Because the time the gel sits on your teeth while being exposed to the LED light, it gets absorbed into your teeth. And overexposing may result in making your teeth sensitive.

You also need to understand that the number of total treatments is going to differ for different people, based on the condition of their teeth. So, if your teeth are badly stained due to caffeine or other such foods, you are going to need more sessions to clear that all up.

Conversely, people whose teeth are just yellowish without any prominent stains, they are going to need fewer treatments. Another thing to consider while planning is the sensitivity level of your teeth. If your teeth are highly sensitive, you should keep the treatment time shorter while keeping the intensity less.

  • Keep your expectations real

Even though these kits are quite effective at lightening your teeth and removing all the stains, you still need to keep your expectations real. You can’t expect to have pearly whites if your teeth are badly stained and are on a point of no return.

In such like case, you obviously won’t be able to see any staggering result. Secondly, you can’t expect to see dramatic results from a single sitting. You need to understand that this is a gradual process and might take multiple treatments until you see any prominent results.

However, it does not mean to discourage you in any way or to tell you that they aren’t worth it. They totally are, but you need to be patient and consistent.

  • Ensure the product is safe

Before making the purchase, make sure that your chosen light is approved by the FDA and is totally safe to use. The good news is, the majority of such products nowadays are completely safe to be used at home. And they are made of equal standards to professional dental equipment.

But still, you cannot completely eliminate the risk of buying a product that is not that safe and may end up harming your teeth and gums. The best way to check their safety is by consulting your dentist. You can simply ask for recommendations or tell him about your preferences.

Secondly, your dentist will also know if your teeth are capable of handling the treatment without getting sensitive. So, if he says no, you shouldn’t go for it. Therefore, whatever you do, do not skip this step.

How to use a teeth whitening light?

Although the usage of these lights is very simple and easy, you might get a bit confused if you are a newbie and your trays require molding. That’s why we decided to jot it down in steps for you to make it easy and quick.

The procedure is very simple and consists of a few easy steps. Please read all the steps carefully and make sure to follow these properly. Also, before every single teeth whitening session, always clean your teeth thoroughly.

  • Boil water

The procedure starts with boiling some water. Ideally, the pan you are using should have a depth of 4 inches. Once the water is boiled, wait for its temperature to drop. Don’t let it get completely cooled down because you need hot water but it shouldn’t be scalding hot.

As the temperature drops a bit, dunk a tray in that water for a few seconds while gripping it from the tap. This will render the tray soft and easily bendable. At this certain point, you have to be highly careful because the tray will begin to bend itself, especially from the corners. This will destroy the shape of the tray. So, make sure it doesn’t happen.

  • Sculpt the tray

Next step is to sculpt your tray. For that, you need to strategically remove it from the water so that it doesn’t twirl. For ensuring that, take it out in an upright position and instantly wrap it all around your teeth and then draw all the air out by sucking it.

For better molding of the tray, you can also make use of your fingers or even your tongue. This will easily shape up the tray as per your teeth. But, you’ll have to hurry because you’ll only have a few seconds until the tray gets totally cooled down.

But, let us tell you, this might need a little practice. So, most probably, your first try won’t be that successful. Therefore, keep on trying until it fits like a glove.

  • Remove frontal tab

Once you are done with the shaping of the tray and are totally content with it, it’s time to remove the frontal tab of the tray. You can easily cut it off using a pair of scissors. Secondly, if the depth of your tray is too much for your teeth, an easy way out would be to remove the upper part of the tray.

You have to take this step with due diligence because you wouldn’t want to end up trimming it excessively. And make sure that the tray seamlessly fits your teeth and is not loose from anywhere. If you come to know that your tray hasn’t been sculpted accurately, repeat the previous steps.

  • Time to put gel in the tray

As we mentioned above, these trays are filled up with whitening gels that need to touch your teeth for starting the action. However, don’t get too generous with the quantity and put a very minimal amount, just about the size of a pea, into the anterior side of the tray. This should be enough to cover your 8-10 frontal teeth.

And we are stressing again, do not use a large quantity of gel, just enough to come in contact with your teeth. Some people think that using excessive gel will give them quicker results, but it is not true. The unnecessary quantity of gel may end up irritating your gums.

For the same reason, while placing the gel filled tray in your mouth; be very careful not to touch your gums. If, somehow, the gel comes in contact with your gums, wipe it off immediately. Do not take it lightly and put it off for later. You wouldn’t want swollen gums for no reason.

Now, keep the tray on for some time. But, if you haven’t done it before, do not keep it on for more than a few minutes, to avoid any discomfort. And then, if you like, you can gradually increase the time duration with every coming session. But, do not go beyond 20-30 minutes in total.

  • Expose your teeth to the light

And now comes the step that you have bought this whole kit for. That’s right, time to use the LED light! The light is used while the tray is on your teeth. So, as soon as you place the tray inside, turn the light on and place in right in front of the tray.

These lights usually have built-in auto timers, so you will not have to turn it off. When the time is up, the light will turn off on its own. But, if you want to keep on doing it for a little longer, you can do so. But remember, not more than 20-30 minutes.  Also, clean the tray thoroughly after every use.

Additional tips

  • You can use continue the treatment until you have reached your required results. 
  • Once you have attained your desired whiteness, it is suggested to carry out these sessions twice a month. 
  • If the first time usage gives you any sort of gum problem, take a break for a week and then again give it a shot. 
  • After each session, give your teeth a little break before eating or drinking anything that may result in staining your teeth. For example, coffee, cola, or tea. Ideally, you should wait at least 2 days before coming back to such foods and drinks.

What to do if  you have sensitive teeth?

If you have highly sensitive teeth, you should get a remineralization/desensitizing gel, apart from your whole kit. This will significantly reduce the sensitivity of your teeth. And if it’s going to be your first time using this light, it’s recommended to have it with your beforehand.

This gel is applied after the session has been completed. Once you are done with the light, clean up your tray and put a very minimal amount of desensitizing gel into it. And then put it in your mouth and leave it there for as long as you are comfortable. You can even do this on a regular basis without waiting for your whitening sessions.


Your smile is one of the initial things that people notice about you. It can either earn you a lot of admirers or can repulse them off. No matter how gorgeous or handsome you are, if your teeth are yellow and tainted, people are not going to have a good opinion about you.

But, luckily, with these teeth whitening lights, you can now get rid of all those stains and yellowness without going to a dentist. And can flaunt your pearly whites to your heartiest desire.
