TWO SETS OF TEETH.
The first set of teeth, twenty in number, gradually become loose after a child is five or six years old, and the second set, thirty-two in number, crowds after them. The second are the teeth which are meant to last all our life-time, and they should be guarded, therefore, with the utmost care.
Sometimes the second teeth crowd so closely that the first become wedged in place. The old tooth should be removed, just as soon as the second can be discovered pushing after it. If this is not done, the mouth will be filled with crooked and unsightly teeth.
THE PRINCIPAL TEETH.
The mother or father of any boy or girl will readily draw a loose tooth, by means of a looped thread. Often, however, a brave child will pull his own teeth, without help. Be on the watch and clear the way for the second teeth. If you don't you will be sorry all your life.
Some children have poorer teeth than others, and the utmost care will not save them from decay. When the first speck appears, go to the dentist. Dentistry has made such improvements during the last few years, that the poorest teeth can be made to last a long time.
What is said of boys and girls?
When and how often should the teeth be cleaned? What should be used for that purpose? What is said of tooth-powders and tooth-picks?
How may stains be removed from the teeth?
What substances injure the teeth? What about cracking nuts and other hard substances with the teeth?
How many teeth has a child? A man? When do the second teeth begin to appear? How long is it intended they should last?
What sometimes takes place? What should be done? What will follow if this advice is not heeded?
How are loose teeth generally pulled? Have you ever known of a boy or girl pulling his or her own teeth? What must you watch for and do? Is there any need of such care?
What is said of some children? When should you go to the dentist?
MUSCLES.
CHAPTER VII.
EXERCISE.
Boys and girls are not likely to believe they need any instruction as to exercise. They are so fond of play that all they ask is a chance and they will use it to the utmost.
That form of exercise is best which brings most muscles into action. It should not be too violent nor continued after one is tired. It should be in the open air, and some kind of game is preferable because it also engages and interests the mind.
