At present, most of the toothpaste on the market belongs to toothpaste with fluoride. Some people hold the view that this kind of toothpaste can prevent decayed teeth, while others think that it would lead to other diseases of teeth. As far as I am concerned, since it has both advantages and disadvantages, we should treat it in an objective way.
First of all, it is suggested to choose toothpaste with fluoride in a scientific way. As we know, brushing the teeth with suitable toothpaste is an effective way to prevent from decayed teeth. But we should first choose a correct tube of toothpaste. In general, children should not use toothpaste with fluoride as they please. Children under the age of three are not allowed to use such toothpaste. If they have too many decayed teeth, they should use this toothpaste under the guidance of doctors. Those children who are at the age of three to six could only use toothpaste with fluoride intended for children or even better, fluoride free toothpaste for kids. Since the sodium monofluorophosphate in the toothpaste would do harms to the health, the amount should be under control. Adults and older children are allowed to use toothpaste with fluoride twice a day.
Secondly, we should know that toothpaste with fluoride would not definitely lead to poisoning. The amount of fluoride in toothpaste is so little that most of it would be washed away by gargling. If some of the fluoride enters the human body through oral mucosa at last, it would not influence the health of an ordinary adult at all. But children should be careful about it. The organs of children who are under the age of six are not mature enough. If too much fluoride enters their bodies, it would probably cause poisoning gradually.
Thirdly, toothpaste with fluoride has nothing to do with dental fluorosis. By the age of six, our teeth have been well developed. If our teeth are healthy enough at that time, they would not be affected later. In other words, no matter how much fluoride such as sodium monofluorophosphate we have absorbed after the age of six, our teeth are free from dental fluorosis. Most dental fluorosis is due to the high content of fluoride in the water.
Every thing has two sides. So does toothpaste with fluoride. Using toothpaste with fluoride in a correct way does help protect our teeth. Scientific research has told us that keeping this habit for two years can reduce the risk of decayed teeth by 25%. And the impact would be much obvious in the long run. But we should keep in mind that toothpaste with fluoride does not suit every child.
