Fluoride

Fluoride is a mineral which exists in water and is also commonly found in foods. The amount of fluoride in the water depends on the area it is sourced from; in areas where the fluoride content is low, additional fluoride may be added to the water supply.

Benefits of Fluoride

Fluoride is necessary for good oral health because it helps to strengthen the enamel-covered surfaces of the teeth. Fluoride also helps to reduce tooth decay; children who have fluoride are less likely to suffer from plaque build-up as the grooves formed on the surfaces of the tooth are shallower when fluoride is consumed; the teeth are therefore easier to clean.

Fluoride Toothpaste

Very few areas of the country have water that has sufficient fluoride content to benefit oral health; for this reason, almost all toothpastes have added fluoride to strengthen the teeth. People who suffer from worn enamel are often encouraged to use fluoride rich toothpaste. In poorer areas where the water supply does not contain much fluoride it may be necessary to use supplements such as gels; these can be applied by the dentist.

Fluorosis

In areas where the water is sufficiently fluoridated people may suffer from fluorosis, which is a condition caused by taking in too much fluoride. This can occur when people use fluoride toothpaste as well drinking fluoride-rich water. Fluorosis is characterised by the appearance of small white dots or lines on the teeth; this condition is often very mild and can be easily spotted by a dentist. Severe fluorosis is rare; the symptoms often include discoloured and uneven enamel.

Is Fluoride Safe?

Research widely supports the use of fluoride; most studies indicate a significant reduction of tooth decay in patients who have a suitable intake of fluoride.
