Fluoride is most known as a dental hygiene products and tooth protection. Most people are exposed to this material through treated drinking water or products such as mouthwash and toothpaste or even their food (such as meat, fish, eggs, and tea leaves).

Fluoride is very useful for preventing cavities and strengthening teeth. If ingested, fluoride enters the bloodstream and is eventually absorbed by the teeth and bones.

Fluoride can also be applied topically to teeth by a dental professional in a dental office. The teeth will readily absorb topical fluoride treatments, and the chemical will remain in the mouth for several hours. Topical fluoride can also be applied at home using products such as toothpaste, mouthwash or mouth rinse, fluoride gels, or fluoride supplements.

Is it safe? When it used properly, fluoride is usually considered a safe for your health. However, high levels of fluoride exposure for extended periods of time may result in harm. For example dental fluorosis, a discoloration of tooth enamel that caused by to much exposure of ingested fluoride. High and long exposure to fluoride could also lead to bone weakening and skeletal fluorosis (joint stiffness and pain).

More extreme, toxic effects may result if someone consumes too much fluoride, this called fluoride overdose. For example, if a small child consumes an entire tube of tooth paste. The symptoms include nausea, vomiting blood, diarrhea, stomach pain, salivation, watery eyes, general weakness, shallow breathing, faintness, tiredness, and convulsions.

So, pay attention to your fluoride use. If you're using fluoride suplements to protect your teeth, you should be watched by your dentist. And if you have childrens, make sure to remain them not to swallow their toothpaste.
