About this deal

Our experts examined some of the key ingredients used in popular toothpastes and found all have good evidence to support them, but one type may work better for you than another. But, bear in mind all fluoride toothpastes provide some protection against enamel erosion, and fluoride is the basis of many an enamel repair claim, as it works to harden or ‘remineralise’ enamel. Even cheap toothpastes contain this, so you don't necessarily need to splash out.

Charcoal, in some higher strength formulations, can also be too abrasive, which could wear down tooth enamel over time. Furthermore some charcoal toothpastes are also fluoride-free, which our experts would not recommend. Hydrated silica, mica and calcium carbonate 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. Toothpaste tablets that you chew aim to cut down on the plastic waste generated by toothpaste tubes. While it wasn't always the case, many toothpaste tubes are now recyclable, as they're manufactured from plastic alone, as opposed to a mix of plastic and metal. There have been some innovations in this area in recent years and there may be good reason to choose a toothpaste targeted at repairing enamel. The higher the hydrogen peroxide content, the more effective the toothpaste will be at whitening. Keep in mind that this could make the product more likely to irritate your teeth and gums.


Vaz VTP, et al. (2019). Whitening toothpaste containing activated charcoal, blue covarine, hydrogen peroxide or microbeads: Which one is the most effective? So as long as you don't have expectations that a whitening toothpaste will change the underlying colour of your tooth enamel, there may be value in buying a toothpaste which makes whitening claims, as it could contain stain-removing ingredients that a standard paste won't have.

Sodium bicarbonate is an effective stain remover with mild abrasive action. It also has some anti-bacterial properties. It’s a favourite for ‘natural’ toothpastes, for example Arm & Hammer uses it across its range. Charcoal Joiner A. (2011). A silica toothpaste containing blue covarine: A new technological breakthrough in whitening. Tablets - the majority of scientific research has been done into how pastes work in combination with brushing, not tablets, so there is no guarantee that these will offer the same protection. Watch out for ones that are also fluoride-free (see above). For extra freshness, a gel-based toothpaste is your best bet but if you want to keep those cavities at bay, go for fluoride toothpaste. Not a fan of that tingling sensation you get after eating hot or cold food? Go for a sensitive toothpaste to curb those sharp sensations. Or if you want to get your teeth looking bright and white, we’ve even got whitening toothpaste to make them shine. And if you want something that can do a little bit of everything, a multi-benefit toothpaste will give you the best of all worlds.Avoid products that contain ingredients you’re sensitive or allergic to, such as flavorings, dyes, or artificial sweeteners. Some people are also allergic to cocamidopropyl betaine (CAPB) and propylene glycol, two ingredients commonly found in toothpaste. All will help with remineralisation and therefore, can be said to repair enamel. But manufacturers of enamel repair pastes are likely to base their claims around the particular formulation of their paste assisting with optimal uptake and absorption of the fluoride. Calcium silicate and sodium phosphate Zinc - a replacement for triclosan which, although not banned in the UK, has now been removed from most toothpastes over concerns about its safety. Zinc has antibacterial properties and is a common ingredient in toothpaste, but experts agree that the most important factor in removing bacteria is brushing effectively. Charcoal whitening toothpaste has seen a huge rise in popularity, despite the Oral Health Foundation and our experts agreeing there’s not enough evidence to support claims around its whitening effect.
