It’s only natural in life to want to put your best self forward. Nobody wants bad breath or yellow teeth. Tea, coffee, smoking, and red wine all stain teeth, but eliminating these things is easier said than done. The truth is that life inevitably conjures something that stains teeth and which you won’t want to do without. However, there is a solution—teeth whitening kits. Teeth whitening has become the talk of the town. As well as their health benefits, these kits are regarded as one of the key grooming essentials for men in today’s business world. But with a widening range of products available, it can be difficult to separate the best teeth whitening kits from the bad. At AGENT we thought we’d make things a little easier for anyone seeking a teeth whitening solution.


Best Teeth Whitening Kits 2019

Our reviews team assessed the latest dental hygiene products and compiled this buyers guide of the best teeth whitening kits. The guide contains reviews of each product, so that you’ll be able to make the most informed decision. Please note that whitening kits are subdivided into three broad types, as follows:


LED Light

One of the fastest methods of stain removal, LED light teeth whitening kits have taken social media by storm in recent months. This method is carried out by inserting a tight-fitting tray into the mouth. Once you’ve achieved a snug fit, apply some gel to the tray and insert back into the mouth, then attaching the LED, or holding it in place with the lips. This method seems to be the fastest option on the market at the moment, although there are people who struggle to see any difference after treatment.


Gel & Tray

The Gel & Tray method is more or less the LED kit minus the light. This method is quite popular because of how easy it is. You are cautioned not to use too much gel, however, as this can become quite uncomfortable and messy.



Strips are the most popular of teeth whitening methods. These kits come in the form of several thin, clear, plastic rectangles that contain hydrogen peroxide gel. These strips are then placed on the teeth, hydrogen peroxide down. After a specified waiting period, the strips are removed.

Best Teeth Whitening Kits Review – FAQ

To wrap up our review of the best teeth whitening kits, we thought we’d throw together this quick FAQs section to answer any questions you might have relating to our reviews above. Check it out below.


Are there any risks to teeth whitening?

Generally speaking, if the instructions on the packet are followed, then no. However, do take into consideration that extended exposure to teeth whitening chemicals may cause some heightened sensitivity to your teeth/gums, which can be very unpleasant. This isn’t really a product we would advise forgetting about when in the middle of a treatment.


Will teeth whitening harm my enamel?

Once again, provided you follow the instructions laid out for you on the cover of the pack, you shouldn’t encounter any problems regarding damage to your teeth enamel.


My teeth whitening kit contains Hydrogen Peroxide / Carbamide Peroxide. Is this safe?

While there are regulations on this type of product, for your own sake, and also for good practice, we always advise checking out the chemical composition of a product to ensure that they are 100% safe. When it comes to Hydrogen Peroxide, the recommended amount in a whitening kit is about 3.5%. Meanwhile, the optimum percentage of Carbamide Peroxide stands at 10%, as certified by the American Dental Association. Provided your teeth whitening kit’s percentage of these chemicals does not overly exceed these figures, it should be entirely safe. That being said, take care not to swallow any of the product when placed in the mouth.


Can teeth whitening kits harm my gums?

Absolutely. This is because the products on our list are designed to go on your teeth, but not the gums. While this is quite inconvenient, it does stand to reason, as often these products demand you keep chemicals pressed into your teeth for many minutes at a time.  Applying such treatment to an already sensitive area like the gums is going to result in significantly  heightened sensitivity.


Can I eat/drink while using whitening strips?

While using the whitening strips it is perfectly fine to drink or talk, however food consumption is definitely not advised, at least not until the strips have been safely removed, and your teeth have been brushed to remove all trace of chemicals.


When should I use my whitening kit?

This is entirely up to you, whenever is most convenient for you is when you should apply your teeth whitening product. That being said, some whitening kits have been known to leave white spots that take a while to disappear, therefore applying your teeth whitening kit at night may be the best time.


How do I mold the tray to my teeth?

Molding your teeth whitening tray to your teeth is usually quite easy. Simply heat it up in hot water, and bit down on it to allow the mold to take shape. Additionally, using a sharp object, you can trim the tray to a better fit for you.


Are teeth whitening kits expensive?

The price range relating to teeth whitening products can vary significantly. With the cheaper products on the market for about $20, and the more expensive products reaching up as high as $80.


I have sensitive teeth, how do I begin my treatments?

We recommend starting slow if you have sensitive teeth. What we mean by this is that it may be a good idea to shorten the amount of time you take for initial treatments to see if it leaves your teeth too sensitive.


Do I treat both the top and bottom teeth at the same time?

Yes, treat both top and bottom teeth at the same time, as this is what the kits are designed for, and you will lose out on the end results if you treat them separately.


When should I see results?

Results should ideally start showing after a few applications, however we recommend continuing until the entire kit has been exhausted for best results.


Is it important to use the whole kit?

Once again, you don’t necessarily have to use the entire kit up, however you will lose out on your final results if you do not use the entire kit.


How long does the whitening effect last?

Unfortunately, the whitening effects are not permanent. Rather, the whitening effect should last a good while, most likely a few months, or in some cases even a year. However, when you notice fading, you can simply top up with more teeth whitening product. Additionally, if you’ve used a teeth whitening kit with a tray before, you need only purchase more gel, as you can re-use your former tray.

How can an LED light actually help with whitening?

The LED light activates the Hydrogen Peroxide / Carbamide Peroxide in your teeth whitening product, which can help yield a better end result.


Can I use a teeth whitening kit with braces?

Yes and no. Yes in that your teeth whitening product won’t harm your braces. However, the results you get from your teeth whitening product will not be even, as your braces will cover areas of your teeth, blocking them from treatment.


How should I store my teeth whitening kit?

We recommend keeping your teeth whitening kit in a dry, cool environment, although some kits can be refrigerated after they have been opened.


Is it safe to keep my whitening kit in over-night?

No. There are limits to how long you are supposed to keep the kit in, usually outlined on the outside of the box. We strongly advise following the manufacturer’s instructions to the letter. Leaving your whitening kit in for a whole night will not yield better results, unless the manufacturer has specifically designed it to.


How many treatments should I do a day?

Once again, this depends entirely on the instructions set out by the manufacturer.


Do I have to use my teeth whitening kit for multiple consecutive days to see a result?

Contrary to popular belief, you don’t actually have to use up your entire kit through a number of consecutive days. In fact you can actually space out your treatments quite a bit.



Wrapping up our FAQs on the best teeth whitening kits, our advise can really be summed up with one statement; follow the instructions! By adhering to the guidelines on the box, you effectively eliminate any risk of having an unpleasant experience with these products. It’s also important to take care not to apply whitening product to the gums, as this will result in heightened sensitivity.
