Fluoride is a naturally occurring mineral that is found in water and some foods. Fluoride can also be synthesised (manufactured) by using chemical processes, and synthetic fluoride is used in toothpaste. It is also sometimes added to drinking water in very small quantities.
The use of fluoride in the UK
In the UK, the Department of Health and The British Dental Association (BDA) recommend that fluoride should be added to tap water because of its proven oral health benefits, particularly in promoting the development of healthy teeth in children, and significantly reducing the incidence of tooth decay. However, it is up to individual local health authorities to decide, in consultation with local health groups and the local community, whether or not fluoride should be included in local water supplies.
Fluoride treatments
In areas where water supplies contain too little fluoride, toothpaste containing added fluoride can be used. Children can also be given mouthwashes, drops and tablets, but you should ask for the advice of your dentist before using these treatments.
Your dentist or dental hygienist can apply topical fluorides during dental visits. These gels are more concentrated than the self-applied fluorides, so they are not needed as frequently. Some adults can benefit from these applications. Fluoride gels can help to reduce root decay, particularly in people with dry mouth.
If you are prone to dental decay, your dentist may advise the use of fluoride supplements in addition to fluoride toothpaste for extra protection. However, it is very important that fluoride supplements are only taken on the advice and instruction of your dentist.
