Cavity or tooth decay is one of the most frequently occurring tooth problems these days. This is caused by bacteria which are present everywhere - in our mouths, toothbrushes and even teeth. In teeth, they start accumulating in the form of plaque, saliva and remains of food. After settling on the teeth, these organisms feed themselves on the food particles remaining there and acid is produced as a consequence of their feasting. This acid corrodes the tooth enamel and is responsible for causing tooth decay. Although human tooth enamel can be repaired to a moderate extent by re-mineralizing, it is not that effective in tooth decay as the rate of corrosion caused by the acid surpasses the rate of restoration.
Fluoride, a natural mineral present in the crust of the earth, helps in reducing the cavity. It is also found in certain water supplies and foodstuffs. It is believed that people who drink fluoridated water can prevent tooth decay up to approximately 67% in comparison to those who do not consume naturally fluoridated water. But the question that arises here is how does fluoride prevent tooth decay?
Another important question that arises is how will one make sure that he or she is consuming adequate amount of fluoride content to prevent cavity?
If people do not consume fluoridated water, use of fluoride toothpaste will ensure that sufficient fluoride is provided to children as well as adults.
Some kind of action to prevent cavity is very important. If left untreated, the bacterial acid can even make the enamel hollow from inside thus causing a hole into the pulp and dentin layers of the teeth. Healthy and disease free teeth are not only vital for oral health, they are also important to prevent certain other health problems including those of the heart.
