2. Curaprox Black is White Charcoal Toothpaste

Activated charcoal products are well-known for their ability to whiten teeth. This ingredient aids Black is White in achieving some stain removal results for some users. However, it is more than just stain removal; overall dental health also plays a role.

This paste is suitable for everyday use and can be integrated into your routine with greater ease and less concern than some other activated charcoal products. It is also more manageable and less messy because it is a paste rather than a powder. Curaprox commands a premium that, to be honest, is difficult to justify when a regular tube of toothpaste is just as good and much cheaper.

4. Activated Charcoal Natural Teeth Whitening Powder

Activated charcoal is a fine-grained black powder made from natural ingredients such as coconut shells, olive pits, slowly burned wood, and peat. When the powder is oxidised at high temperatures, it becomes activated. Activated charcoal is extremely porous and adsorbent. It has a large surface area as well.

Unlike absorbent substances, the adsorbent nature of activated charcoal allows it to bind to toxins and odours rather than soaking (absorbing) them up. Activated charcoal is not to be confused with the charcoal used for grilling. Although similar, barbeque charcoal is designed to be used as a fuel and emits carbon dioxide when heated. It has the potential to cause cancer. Activated charcoal, on the other hand, is free of these toxins.

7. Pro Teeth Whitening Co. premium dental whitening strips

We were sceptical at first that any strips could significantly whiten your teeth, but we were proven wrong. After ensuring that your teeth are as dry as possible, apply the two strips to your upper and lower teeth and wait 30 minutes before removing and cleaning any residue. While they were uncomfortable for a few minutes, the time flew by and we were able to go about our evening with ease.

Our teeth looked whiter after a week than they had in years, and the effects only improved over the course of the 14-day treatment. By the end of it, our tester had even made a friend who had previously undergone professional whitening jealous. The secret ingredient here is activated charcoal, which is also free of peroxide.

How to choose the best teeth whitening kit

What kinds of teeth whitening kits are available?

1. Whitening strips: These easy-to-use adhesive strips contain a whitening gel that you stick to the surface of your teeth, usually for around half-an-hour, sometimes longer – a process that needs to be repeated daily for a set amount of time, generally around a fortnight.

2. Whitening toothpastes: These work harder than regular toothpastes to remove stains and plaque. To achieve this, they may contain a mild abrasive or bleaching agent, while others contain activated carbon. You can use them in conjunction with other home kits.

3. Home bleaching kit: These can look horribly complicated, but a good kit will have a comprehensive user manual to guide you through the steps, which basically involve dipping the moulds into boiling water before fitting them onto your teeth (a bit like a mouth guard). You then add the whitening gel into the tray, which you insert against your teeth. They give you quick results.

4. Custom lightening trays: This is the type of kit that dentists are most likely to recommend, but you will need to work with them so they can mould your tray specifically for your teeth and show you how to apply the gel and tray at home. If you want to work with a professional and are prepared to spend a bit more, but can’t afford laser or LED treatment, this will get you the best results of all the kits listed here.

5. Pre-made tray: This is the poor man’s version of the custom lightening tray – in that the process is the same, but the tray isn’t fitted to the exact shape of your mouth. Provided you can cover the entire surface area of your teeth with your tray, it’s a good compromise. If your teeth are a little crooked though, you may not get an even result.

6. LED gel kit: The LED teeth whitening light won’t make your teeth whiter, but it will accelerate the teeth whitening gel and make it more effective at breaking down tough stains. If you don’t have the custom-made tray created to your exact mouth shape, then the LED light is good for reducing the amount of time the gel has to stay in your mouth.

7. Teeth whitening pen: This kit contains a thin, plastic tube containing whitening gel and is small enough to keep in your handbag or even your pocket, making it highly transportable. It’s good for touch-ups and hard-to-reach places.


Do teeth whitening kits actually work? The answer is yes – as long as you don’t expect immediate results. Home whitening kits are a cost-effective and convenient way to whiten your teeth. Although individual results vary, it is possible to lighten your teeth several shades in a week or two. Because safety is a concern with at-home teeth whitening, we recommend that you select a product manufactured in a country that strictly regulates whitening products, such as the United Kingdom, the United States, or the European Union.
