} ARE OUR TEETH CONSIDERED A LIVING THING??
Wednesday, January 27, 2010 @ 9:04 PM


To find out if an object is considered a living thing it has to have movement,excretion,respiration,irritability,growth,reproduction,adaptability and nutrition.Although all living things do not need to have the eight characteristics to be considered as a living things it should have a few of it to be catogrised as a living thing and as part of my task i have decided to find out if our teeth is considered a living thing.




YES it is considered a living thing because

  • MOVEMENT
    Our teeth are not permanatly set into the bone they do move. For example when we put braces they put pressure on our tooth and thus they regroup and our teeth shift. The teeth tend to move together during adolescence as the lips and facial muscles continue to get stronger and exert more pressure, after about the age of 50 the opposite happens. Our front teeth also start to fan out. our teeth pushes forward and forms gaps.
  • GROWTH
    When we are just born we do not have teeth as we grow our teeth grows too around our toddler ages our teeth drops and gets replaced with adult teeths.When we are around the age of 21 our wisdom teeth starts to grow.therefore our teeth do grow why do teeth sometimes grow "crooked"? The reason varies with each person, but scientists say that the way the jaws have developed in modern man can cause this problem. It seems that man's jaws today do not always provide enough room for his teeth. So they appear in a crooked position or become shifted during the period of growth.
  • NUTRITION
    our teeth needs nutrition too.The main nutrition it needs is calcium to bulid strong teethfor example when a woman bears too many children too quickly, she often begins to have dental problems. If she does not have enough calcium to meet those other needs of herself and the calcium needs of her baby, the calcium in her teeth will begin to be used up.Our teeth also need calcium to maintain Lack of calcium or vitamin D in the diet will result in poor enamel, which will encourage early decay.
THEREFORE IT OUR TOOTH IS CONSIDERED A LIVING THING!!:D
