Fluoride

Tooth decay, also known as dental decay or dental caries, is a major health concern worldwide and is still a big problem in the UK. Despite being preventable, it's one of the most common reasons for hospital admission in children.

Tooth decay is the destruction of tooth tissue caused by acids made by bacteria in dental plaque. Dental plaque is a sticky film that constantly forms on the teeth. Each time you have sugary food and drink, the bacteria in plaque produce acid that attacks teeth.

If you eat or drink sugary foods frequently throughout the day, you have more "acid attacks" which can lead to tooth decay. This can eventually lead to cavities (holes) in the teeth and infection, which is why teeth sometimes need to be removed.

A range of toothpastes are available that contain different levels of fluoride. The amount of fluoride thats in the toothpaste can be found on the side of the tube and is measured in parts per million (ppm).

Toothpastes containing 1350-1500ppm fluoride are the most effective. Your dentist may advise you to use higher-strength toothpaste if you or your child is at particular risk of tooth decay.

• Children under three years old should brush twice daily, with a smear of toothpaste containing no less than 1000ppm fluoride.
• Children between three and six years old should brush at least twice daily with a pea-sized amount of toothpaste containing more than 1000ppm fluoride.
• Adults should brush at least twice daily with a toothpaste containing 1350-1500ppm fluoride.

Dont use mouthwash at the same time as brushing. Use it at an alternative time, because it washes away the fluoride in the toothpaste

They should be used every day, in addition to brushing twice daily with toothpaste containing at least 1350ppm fluoride.

Rinses should be used at different times to brushing to avoid washing the toothpaste off your teeth, as this reduces the beneficial effects of the fluoride in the toothpaste.

Fluoride varnish

Fluoride varnish can be applied to both baby teeth and adult teeth by a dentist. The process involves painting a varnish containing high levels of fluoride onto the surface of the tooth every six months to prevent decay. It works by strengthening tooth enamel, making it more resistant to decay.

From the age of three, children should be offered fluoride varnish treatment at least twice a year. Fluoride varnish should be offered two or more times a year for children of all ages with tooth decay or those at high risk of developing it.

Ask your dentist about fluoride varnish. Find a dentist near you.
