Buying The Right Teeth Whitening Gel: Factors to Consider

After going through our comprehensive list of the very best teeth whitening products on the market today, you should be quite delighted at the options we’ve provided. Since they’re top ten, they should be the best and most recommended for everyone, right?

The answer is no. This will probably astound some of you, as the thought then arises in your minds: but they’re all gels containing more of less the same concentrations of teeth-whitening ingredients! You could even go further to state that they’re all the same as they do the same basic thing, which is to whiten browned and yellowed teeth!

The truth is that not all gels and products are suitable to be used by everyone. No matter what it says on the pack, or how many rave reviews the product has got on Amazon, it would be silly to go for just any product, especially when it is not recommended by a specialist.

But not to worry, because in this article, we will also be discussing the important factors that we think that you should consider before buying a teeth whitening product. Read on and find out more!

Clinically tested and proven products

The very first thing to consider is the clinical suitability and certification of the product that you have chosen to buy. As fancy as they seem, and as easy as they are to use, teeth whitening gels and their accompanying oral care kits are inherently medical products. Therefore, they should be considered with the discretion with which you’d use a curious but new medical tablet or sachet claiming to cure migraines in just 3 minutes.

Even if the teeth whitening product you want to buy is a household name, a popular brand, one with hundreds of reviews on Amazon, you should always ensure that it is recommended by a dentist. You should also take care to ensure that it will produce the exact result that you want, when the recommended steps are adhered to. For instance, GLO is a popular brand that is recommended by many dentists, having also undergone clinical trials to verify its efficiency. Thus, the GLO brand has been proven to be efficient at teeth whitening, able to make teeth 5 shades whiter in just 5 days.

Another great example of a clinically proven, tested and trusted product is iSmile teeth whitening kit that comes with LED light. Stick to clinically trialled and proven products and enjoy efficient, fast results that will come without hassle.

Also a good product, but didn’t made it in to our Top 10.

Rate and speed of teeth whitening

If you have made the choice to go for a teeth whitening gel, then it stands to reason that you have chosen this option because you are now conscious of the fact that you have badly discolored teeth, and want to take a drastic step toward eliminating the stains.

It also stands to reason that you’ve probably heard of the dental whitening procedures with special light and hydrogen peroxide, and have decided to go for a cheaper option rather than spend hundreds of dollars in dentist fees.

Just as well, it stands to reason that you have done some research and discovered that there was a faster, cheaper alternative to a dentist’s procedure, and realise that the alternative is just as good as the real thing.

Having decided on these, you are most likely looking for quick results. In fact, it could be argued that the majority of folk who go for the whitening gel alternative do so because it is much quicker. After buying the product, it is relatively easy to use and does not require you to schedule an appointment with a dentist.

Teeth whitening kit with LED is faster

Real teeth whitening takes a lot of time, plus repeated exposure. It is important to also note that the application of heat helps to speed up chemical reactions. Whatever product you choose to make use of, the process is the same: the chemical compound in the gel will dissolve the stains on the teeth via a chemical reaction similar to bleaching.

If you want the best teeth whitening results, then you should use the kits that come with LED accelerator light and extra bulbs. Nevertheless, you should note that this procedure takes much longer to perfect. Thus, the choice is yours. Choose wisely!

Gum and teeth sensitivity and irritation

It is a given that several teeth whitening products will cause you some form of oral irritation, Whitening strips in particular, along with gels and trays are likely to cause some irritation.

The best products, however, cause very minimal irritation and are rather very convenient to use. Some of the brands listed above have a very good reputation regarding this and can be directly applied to your teeth without touching your gums.

Whitening Trays

Most of the products listed above come with tooth whitening trays that you can use at home. These easy-to-use devices are very convenient to use and produce highly efficient and visible results. This is because they contain a considerable amount of bleach.

When recommended by dentists, special, custom molds of your teeth are taken by the dentist, who will then model fitted trays made out of soft, malleable plastic for use on your real teeth. These trays act as a buffer to ensure that the bleach does not run off from the oral cavity, specifically the teeth, while also preventing saliva from disrupting the chemical process via the dilution of the bleach.

Thus, gel wastage is minimized, as is gum irritation. If you buy a random teeth tray, chances are that it will not fit perfectly over your teeth, which may cause the bleach to leak and affect your gums negatively. The Smile Teeth Titan teeth whitening kit is an excellent choice for this, as it offers a universal fitting tray that you can use even without a dentist’s recommendation.

The gels themselves are the bleaching agents, and are usually stored inside of syringes. The gels can thus be easily applied to the trays before they are used. When recommended by a dentist, the bleach concentration can be adjusted if need be.


For many, the single most important decider for which teeth whitening alternative to go for is cost. If you’re looking to get rid of stains on your teeth, then you should be aware that certain ingredients are more safe than others. In addition, the results might not be satisfactory, if you choose the wrong product.

Teeth whitening, despite its cosmetic appeal, should be first and foremost considered as a medical procedure. If a gravely sick patient would prefer to pay several hundred dollars for guaranteed, qualitative healthcare, then you should not look to cut corners when choosing a teeth whitening alternative simply because it comes off as purely cosmetic.

Accordingly, if you spend less money, chances are that you will end up with a low quality product that will not deliver desirable results (if you’re not injured outright in the process). Oral care is important, and should be considered with utmost care and professionalism.

Thus, if you have to use a teeth whitening product, it is advisable that you use a product that is technologically and clinically proven to give you that bright, white smile that you so desire.

Advantages of Teeth Whitening gel

The advantages are quite clear: they give you a brighter smile, and are easy-to-use solutions and alternatives to dental procedures. In addition, they are rather quite cheap! Get a teeth whitening product today for a whiter smile!

Disadvantages of Teeth Whitening gel

As a dentally-proven remedy to teeth stains accumulated over a long period of time, teeth whitening has scant few demerits.

Nonetheless, it is important to state the major demerit of using such products: gum irritation. If applied wrongly, the gel can irritate your gums and cause them to become pinkish and swollen. The best products come with precise manuals, however, so that you can apply them correctly.

The best option is to use such a product as prescribed by a dentist.

Ingredients in Teeth Whitening Products

The active ingredients and agents in teeth whitening products are predominantly of the bleach type i.e peroxide. Most teeth whitening products are made of carbamide peroxide instead of the hydrogen peroxide that is used by dentists in actual dental cleaning procedures.

graph hydrogen peroxide and carbamide peroxide
Hydrogen peroxide itself is a very strong bleaching agent, while its twin carbamide peroxide helps to break down the former.

You are not advised to buy a bleaching agent over the counter for the purpose of bleaching and whitening your teeth, as the concentrations of peroxide are often as high as 45%. Teeth whitening strips such as Crest 3D whitening strip, on the other hand, have a very small concentration of the bleaching agent (less than 10%), which will work just fine but will probably irritate your gums if used frequently.

Other active ingredients include, carbopol, flavouring, glycerin and sodium hydroxide.

Frequently asked questions

What is the scientifically safest way to whiten my teeth?

The safest method is to get it done in a hospital by a real dentist. The agents that are used are much stronger, but the dentist uses special means to protect your gums and your mouth. In addition, the beaching agent is usually concentrated, while any complications that arise can be easily dealt with by the dentist, who is medically the most qualified person to administer treatment of any sort to your teeth.

Should I use whitening strips, a gel, or the full teeth whitening kit?

Teeth whitening can be a tricky affair. The strips are a great, economy choice that perform the function as well as well as the other devices. However, a strip is much safer, and it is far less likely for you to accidentally poison your gum and your mouth with the bleach.

A syringed gel is a great choice as well, especially if used with a fitting tray. It is important, though, to buy a product that is reputed for quality and is certified by appropriate dental affiliations.

The full kit is the best option, even if it is not the most economic.


So, here are the ten best products based on acute and objective observation. We hope you’ve enjoyed reading through it as much as we enjoyed writing it. Now you know. That bright, white smile is not so distant afterall.
