If you regularly drink tea, coffee, red wine and other staining foods and drinks, switching to a whitening toothpaste can help stop the build up of everyday stains. They can generally take a few weeks to start seeing results." Teeth whitening products aim to remove surface stains on the tooth and penetrate the enamel, to break down the discoloured molecules within. This leaves teeth looking whiter overall. The solutions often contain active bleaching agents such as hydrogen peroxide or carbamide peroxide, which remove the deeper stains from your teeth. For the Billion Dollar Smile USB Teeth Whitening Kit, you use the gel pen to paint an even layer of gel over your teeth, put the mouth guard in your mouth to cover your teeth, and turn on the light. It should run for 16 minutes with a full charge, but if you haven't charged it you can run it while it's plugged in.

Hydrogen peroxide is a common whitening agent used across various traditional products. It is irradiated by precise laser wavelengths that thermocatalyse the peroxide and cause it to release free radicals. These penetrate the tooth structure and lead to an oxidation reaction, breaking down the organic molecules into smaller, colourless compounds and thus whitening the colour of the tooth.

March 2022. https://www.cbi.eu/market-information/natural-ingredients-cosmetics/what-demand [Accessed December 2022] The mouth guard is where you place the whitening gel. It’s a fixed-shape tray so you don’t need to go through the process of moulding it to your teeth, which can be fiddly. However, depending on the size of your teeth or jaws you might find it a loose or tight fit.With regards to a possible substitute for peroxide, phthalimido-peroxy-caproic acid – or PAP as it is more affectionately known – is a powerful oxidising agent. The difference between this and peroxide is that PAP does not release free radicals. As such, it is not associated with the tooth sensitivity, gingival irritation or demineralisation that peroxide has been linked with. [ix] This means that it breaks down stains without any potential side effects, providing a win-win for patients and professionals alike. In addition to its enhanced safety characteristics, PAP has also been shown to outperform 6% hydrogen peroxide when it comes to stain removal and tooth shade improvement. [x]

The recommended treatment course is still six days, but you should get more than that from this kit since it contains more gel and has a more economical application system. Some people experience tooth sensitivity when using strips, but some strips are gentler than others. Meanwhile, home bleaching kits can cause blistering and sensitivity to the gums and lips, although gum shields are provided to help avoid this – and even if some of the solution leaks on and does cause soreness, these side effects only last a few days. Some kits warn against using during pregnancy or when breastfeeding and kits also usually suggest a minimum age of use.

Clare Jayson, Founder of Billion Dollar Smile, agreed they were effective and a good idea to use, but advised to be patient with the results - and don't expect miracles. Apart from the strips in the teeth whitening strips kit and the electronic components, everything else in the Billion Dollar Smile teeth whitening kits is made in the UK. This is useful to know, since you can be assured that production standards are high and that strict regulations have been met for the ingredients. Billion Dollar Smile review – Our overall rating: ★★★☆☆ (3/5 stars) For dental professionals, the challenge is to find a whitening product that you can trust to deliver reliable results, while also containing the natural ingredients that patients seek. Billion Dollar Smile purple toothpaste from Oraldent provides such a solution. Designed from peroxide-free, vegan-friendly, cruelty-free and all-natural ingredients, the unique formula is clinically tested and scientifically proven to work. It utilises PAP, papain enzymes, bromelain, hydrated silica and several other natural substances to gently but effectively whiten the teeth with minimal risk of sensitivity, soft tissue damage or demineralisation. The mere mention of teeth whitening can produce fear in man,y though, as they imagine cheap, ineffective treatments that do little more than increase sensitivity. The other side of it is exorbitantly expensive surgical treatments that only the likes of Simon Cowell can afford. 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, the LED light is good for reducing the amount of time the gel has to stay in your mouth.

Billion Dollar Smile places a lot of emphasis on their inclusion of a lot of natural ingredients in their whitening gel. It doesn't contain any peroxides, which are typically used for professional teeth whitening and in many home kits. This should reduce the risk of sensitivity, but it may also impact results because peroxides are the leading tried-and-tested teeth whitening ingredient. Other ingredients such as sodium bicarbonate, sodium perborate, activated charcoal or even coconut oil offer a more natural alternative, although these are usually considered less effective, as they mainly only remove surface stains. Amazing product, my teeth were so much whiter after only a few goes. Highly recommend the product!”
