Millions of people may be missing an important step in keeping their teeth and gums healthy, according to leading UK dental experts.

Advice from some of the UK’s biggest oral health organisations says brushing twice a day may not always be enough to help prevent gum disease and tooth decay.

The guidance, backed by the Oral Health Foundation and created following an advisory board meeting by Kenvue with representatives from the British Society of Periodontology, the British Society of Dental Hygiene and Therapy and the British Association of Dental Therapists, says adding the right mouthwash to a daily brushing routine can help improve gum health and reduce harmful bacteria in the mouth.

Experts behind the advice say many people struggle to remove enough plaque through brushing alone, particularly around the gum line and between teeth, even when brushing regularly.

Dr Rachel England, Head of Policy and Advocacy at the Oral Health Foundation, says: “Most people understand the importance of brushing their teeth, but many will be surprised to learn that brushing alone may not always be enough to keep teeth and gums healthy.

“Research shows that using the right mouthwash as part of a daily routine can provide extra protection against gum disease and tooth decay.”

The new advice is based on a review of scientific evidence and dental guidance used by professionals across the UK and Europe.

Dental experts are also urging people to rethink what they do after brushing their teeth. They say people should spit out excess toothpaste after brushing but avoid rinsing with water straight away, as this can wash away the fluoride left behind on the teeth.

The guidance also recommends using mouthwash at the correct time. Mouthwash used for gum health should be used after brushing, while fluoride mouthwash for cavity protection should be used at a different time of day.

Experts say not all mouthwashes work in the same way. Studies show that products containing ingredients such as essential oils, chlorhexidine or CPC can help reduce plaque and early signs of gum disease when used daily as part of a good oral health routine.

Dr England adds: “People should not feel they have failed if they still experience gum problems despite brushing regularly. Some parts of the mouth are difficult to clean properly, which is why dental professionals often recommend extra steps to help keep the mouth healthy.”

Around half of UK adults are estimated to have some form of gum disease, while tooth decay remains one of the most common health problems worldwide.

The organisations involved hope the new advice will encourage more people to speak to their dental team about the best routine for their own teeth and gums.
