Conclusion
Now that you have finished your adventure you should feel a sense of accomplishment!!! Excellent Job! Here is a review of what you have learned about the teeth..
The teeth are the hardest substances in the human body. Besides being essential for chewing, the teeth play an important role in speech.
Parts of the teeth include:
• Enamel: The hardest, white outer part of the tooth. Enamel is mostly made of calcium phosphate, a rock-hard mineral.
• Dentin: A layer underlying the enamel. It is a hard tissue that contains microscopic tubes. When the enamel is damaged, heat or cold can enter the tooth through these paths and cause sensitivity or pain.
• Pulp: The softer, living inner structure of teeth.Blood vessels and nerves run through the pulp of the teeth.
• Cementum: A layer of connective tissue that binds the roots of the teeth firmly to the gums and jawbone.
• Periodontal ligament: Tissue that helps hold the teeth tightly against the jaw.
A normal adult mouth has 32 teeth, which (except for wisdom teeth) have erupted by about age 13:
• Incisors (8 total): The middlemost four teeth on the upper and lower jaws.
• Canines (4 total): The pointed teeth just outside the incisors.
• Premolars (8 total): Teeth between the canines and molars.
• Molars (8 total): Flat teeth in the rear of the mouth, best at grinding food.
• Wisdom Teeth or third molars (4 total): These teeth erupt at around age 18, but are often surgically removed to prevent displacement of other teeth.
The crown of each tooth projects into the mouth. The root of each tooth descends below the gum line, into the jaw.
Teeth Conditions
- Cavities (caries): Bacteria evade removal by brushing and saliva and damage the enamel and deeper structures of teeth. Most cavities occur on molars and premolars.
- Tooth decay: A general name for disease of the teeth, including cavities.
- Tooth Sensitivity: When one or more teeth become sensitive to hot or cold, it may mean the dentin is exposed.
Teeth Treatment
- Brushing Teeth
- Flossing Teeth
- Rinsing Teeth
