  9. Wisdom Teeth A tooth becomes impacted when there is a lack of space in the dental arch and its growth and eruption are prevented by overlying gum, bone or another tooth.

  10. Enamel: Hard, shiny, white material which is even harder than bone. Protects the tooth from injury Parts of the Tooth CROWN: the part of the tooth above the gum. ROOT: the part which holds the tooth in the jaw bone

  11. Parts of the Tooth cont… Gum: The place where the crow and root meet Dentin: It is a hard, bony material which makes up the biggest part of the tooth

  12. Cementum: is a layer of bony material which covers the root. It acts as a protective shield. Pulp Cavity: is a bone-enclosed hollow space at the center of the tooth. It contains a soft, spongy substance called pulp, the nerves gives us signals of infection or injury
