Many studies have been done that prove the effectiveness of fluoride in reducing tooth decay.
For a baby, fluoride in the water forms a harder material for their developing teeth which makes their emerging teeth stronger. A study of more than 17,000 Australian children found that fluoridated water’s “preventive effect was maximized by continuous exposure both before and after eruption (i.e., when teeth first appear in the mouth).” This finding refutes the claim made by fluoridation opponents that topical application of fluoride (the use of toothpaste) is the only effective way to secure fluoride’s benefits.
Fluoride in toothpaste strengthens and remineralises the teeth and is similar to calcium. “The use of fluoride in toothpastes have been researched extensively and have shown to have significant effect to reduce decay and improve oral health.
“Fluoride helps repair any damage before it becomes serious. A constant low-level supply of fluoride is best for this, with fluoride in your drinking water and toothpastes acting like a constant ‘repair kit’ for your teeth,” Dr Christopher Ho from CARE Dentistry advises.
People are now keeping their teeth for longer than ever and a professional fluoride application at your dentist will contribute to stronger, caries resistant teeth and also the prevention of caries in the cementum (root surfaces) which is not as hard as the enamel. Fluoride will help strengthen the cementum to prevent caries in this tissue. For those with tooth sensitivity, it will also help to desensitize those surfaces.
