Fluoride has been used for over 50 year in dental care- it is used in most common toothpastes all over the world, and you will even find it in your drinking water in Leeds- it is a great benefit to the teeth…or is it? Fluoride has proved itself in the fight against to decay- it helps to maintain a good level of saliva in the mouth that breaks down bacteria naturally and neutralises acids. It regenerates minerals in tooth enamel, making it harder and helps to reverse any decay that might be in its early stages- hence it can be found in most oral hygiene products, from mouthwashes to flosses. A dentist can also administer fluoride directly on the teeth for extra protection and to fight gum disease. However, some dentists are turning away from the use of fluoride because it is toxic and this is especially a concern in children- they tend to eat more paste than they brush with. This can not only lead to the teeth discolouring and dental fluorosis, but also a build up of fluoride the brain (and in some cases death). There are fluoride free toothpastes available on the market, aimed at kids, until they have kicked the habit of swallowing the stuff! Like most things, fluoride should be used in moderation. There is enough information out there to make your own informed decisions on the subject, but there is no doubt about the protection qualities that fluoride has for the teeth.
