Structure Of A Tooth

key notes :

Introduction to Teeth:

• Teeth help us chew food, speak clearly, and give shape to our face.
• Humans have two sets of teeth in their lifetime: baby teeth (milk teeth) and permanent teeth.

Parts of a Tooth:

• A tooth has three main layers:
  • Crown: The top part of the tooth that is visible above the gums.

• Neck: The part between the crown and the root, located at the gum line.
• Root: The part of the tooth that is hidden under the gums and holds the tooth in place.

Different Layers of a Tooth:

• Enamel:
  • The outermost layer of the tooth.
  • It is hard and strong to protect the inner parts.
• Dentin:
  • The layer under the enamel.
  • It is softer than enamel and yellowish in color.
• Pulp:
  • The innermost part of the tooth.
  • It contains nerves and blood vessels that keep the tooth alive.

Gums:

• The soft tissues that surround the teeth and protect the roots.
• Healthy gums are pink and help keep teeth strong.

Types of Teeth:

• Incisors: The front teeth used for cutting food.
• Canines: The pointed teeth next to incisors, used for tearing food.
• Molars: The teeth at the back, used for grinding and chewing food.

Taking Care of Teeth:

• Brush your teeth twice a day.
• Avoid eating too many sugary foods to prevent cavities.
• Visit the dentist regularly for check-ups.
