When the child becomes three years they have about twenty teeth already seen. These milk teeth are very important as they help in chewing and in talking development and the jaws to develop in the age between the age of six and seven. When the tooth falls off the roots of this teeth dissolves eventually.
When the milk teeth fall off it is replaced with permanent teeth after six years but this replacement of permanent teeth will last about seven years only. It means you will have both milk and adult teeth till twelve to fourteen years. This is called mixed dentition. Once you are fourteen years you will end up having only adult teeth and about twenty-eight teeth in number. So your permanent or adult teeth will last forever and is also important to take care of them because once they fall off new ones will never come.
