Having sensitive teeth is something most of us have experienced. It is so common that many of the patients in London and around the world make toothpaste for sensitive teeth their brand of choice. Dentists in London report that the complaint they hear the most is that of patient’s teeth being very sensitive. It was found that one in five adults have some sort of tooth sensitivity.
Those who have sensitive teeth know that when something hot, cold, sweet, or sour is felt by the teeth, it gives off a sharp pain. It does not last long but the intensity of it is enough to make one stop and take notice. Some individuals have teeth that are so sensitive; a puff of cold air to the mouth will cause the pain to occur.
Most sensitivity of the teeth is a result of the enamel coating on the outside of the teeth being worn down. This enamel is the covering for the dentin and when it is gone, the pain occurs. This sensitivity can also be a result of someone who grinds their teeth, has missing fillings, has a tooth which has been cracked, disease of the gums, receding gums, plaque on the teeth, abrasive brushing, whitening of the teeth, eating foods that are acidic.
If the sensitivity gets worse, you should see a dentist who can help diagnose the problem and find ways to help the condition. They have a treatment known as iontophoresis that applies fluoride to the tooth through electrical currents to help the problem.

Now, this got me really reeling! It’s been a long established fact by the dental profession that fluoride and fluoridated products are really good for teeth. According to the old school of research, fluoride was readily absorbed by the outer surface of teeth called as enamel to make a really hard coating .This made the tooth stronger and more resistant to cavities. But a few theories floating around the internet are giving me second thoughts! Fluoride’s anti cavity properties have made it popular enough to be added to mouthwashes, toothpastes, as well as the water supply of nearly 47 states of the US since the 1940’s.But the story behind the discovery of fluoride is really surprising. A few years ago, fluoride was one of the most dangerous by products of the explosive, fertilizers and aluminum industry. It was produced in excess and extremely difficult to store and dispose. A single scientist, working for the American Aluminum Company, was credited with discovering these so called beneficial effects of the fluoride. The American Aluminum Company was at the time one of the biggest manufactures of fluoride as the waste by product.

Kinda seems fishy!
