Potassium nitrate is the desensitising ingredient found in Sensodyne Original - perhaps the most well-known toothpaste formulated for sensitive teeth. There’s good evidence that potassium nitrate builds up over time to desensitise nerves. However, the time taken to work is the downside – it can take up to two weeks to be effective. Stannous fluoride Here's a rundown of the evidence behind typical ingredients found in whitening toothpastes: Hydrogen peroxide Some whitening toothpastes use abrasives, such as microbeads, to remove stains. These can be effective for tough stains and for removing dental biofilm plaque from teeth. These are all mild abrasives that will help to clean and polish your teeth, removing surface stains. A toothpaste's level of abrasion is known as its RDA (relative dentin abrasivity). Most will have a fairly low level but whitening toothpastes can be more abrasive. Unilever’s Regenerate Enamel Science Advanced toothpaste claims to regenerate enamel through the action of calcium silicate and sodium phosphate interacting with hydroxyapatite (what tooth enamel is made of).There are three types of fluoride: sodium fluoride, sodium monoflurophosphate and stannous fluoride. Extrinsic staining surface stains typically caused by smoking, or drinking tea, coffee or red wine. These respond well to brushing with whitening toothpaste, which contains ingredients to help remove stains, but won’t change the underlying colour of your teeth. A common concern is that consuming fluoridated tap water and using fluoride toothpaste could lead to excessive fluoride consumption, but the NHS says dental fluorosis, a condition that causes pitting or discolouration of children’s teeth caused by excessive fluoride, is uncommon in the UK, as fluoride in the water supply, where it is added, is carefully regulated.

Whilst this ingredient is used for professional whitening (i.e. changing the colour of your teeth), the UK legal limit for toothpaste is a concentration of 0.1%, compared with 6% in a professional whitening treatment, so it's unlikely to have much effect on underlying enamel colour in toothpaste form. Optical brighteners Intrinsic staining happens inside your teeth and can be caused by trauma, certain medical treatment or excessive childhood fluoride consumption (but this is rare in the UK). Teeth also yellow as we age, due to thinning enamel. The only way to remove intrinsic staining is bleaching through dentist-administered professional products (using hydrogen peroxide).Dantas AAR, et al. (2015). Can a bleaching toothpaste containing blue covarine demonstrate the same bleaching as conventional techniques? An in vitro, randomized and blinded study. That being said, some of the fancier toothpastes do have some extra weapons up their sleeve.
