Teeth Chart- Types of Teeth, Functions and Location
- We have 32 permanent teeth, arranged in pairs in the upper and lower jaws.
- A tooth has two parts - crown and root. Crown stays above the gum while the root stays below the gum line.
- The hard white covering of the tooth is enamel, hardest material of the body.
- Plaque forming bacteria produce an acid, which erodes the enamel and leads to cavities.
- Wisdom tooth is a third molar which appears in early teens or late twenties.
