Enamel the outer layer of the crown of a tooth is made of closely packed mineral crystals.
Enamel is a very important part of the tooth, it is a protective layer made up of very dense mineral crystals. Everyday some enamel is lost due to a process called demineralization, this happens when plaque releases a acidic byproduct that harms the teeth. Luckily your body naturally tries to fight back against demineralization and attempts to try to restore this destructive process. This is done through minerals in the saliva, such as fluoride, calcium and phosphate, are deposited back into the enamel.
The reality is that your body probably will not be able to fully combat the effects of demineralization without some help. Too much loss of minerals without enough replacement leads to tooth decay. Fluoride helps in two ways. When children drink fluoride in small doses, it enters the bloodstream and helps to build strong permanent teeth; also fluoride can strengthen teeth from the outside, when it comes into contact with the teeth. When teeth are strengthened with fluoride, it makes it harder for the acids to erode the enamel of the teeth.
Fluoride is all around us, it is in foods and used as a supplement in some drinking water. This helps benefit the tooth development in people younger than 16. Topical fluorides are also available in many dental tooth pastes or rinses. While you are only using the fluoride for a short time, the elevated levels of fluoride levels last for hours after. When you go to the dentist professional fluoride treatments are given. They are applied as a varnish, foam, or gel. When the dentist applies fluoride to your teeth, it is in a much higher concentration than over-the-counter treatments. In certain cases special fluoride concentrations are prescribed to children who live in areas where fluoride is not added to the drinking water. Normally these supplements will be given to children between the age of 6 months to 16 years old.
Fluoride supplements should be given if your drinking water is not fluorinated. They are available in liquids and tablets. Your dentist or your pediatrician will need to prescribe them to you.
Is it Harmful
Fluoride is safe if it is used in safe dosages, but in heavy dosages it can be harmful, so it is important to monitor the fluoride levels if you are using it in your home. City water is constantly monitored to maintain save fluoride levels.
