Study Notes
Hungry Brains
- Enamel is the toughest substance found in the human body.
- Essential nutrients for dental health include calcium and Vitamin C.
- Dairy products such as milk, cheese, and cottage cheese are excellent calcium sources.
Tooth Structure
- Enamel is the hard, white outer layer of a tooth.
- Beneath enamel lies dentine, which serves to protect the softer pulp inside.
- The pulp contains nerves and blood vessels, extending down to the tooth’s root.
- A hole in the root allows connection between nerves and gums.
Caring For Our Teeth
- Proper dental care is crucial for overall health.
- Symptoms of tooth decay include bad breath, toothache, bleeding gums, and cavities.
Cavity Formation
- A cavity is created from tooth decay that results in a hole.
- Food particles trapped in teeth can lead to bacterial growth in the mouth.
- Bacteria produce acids that form plaque, gradually damaging the enamel.
- Once decay reaches the dentine and pulp, it can result in painful toothaches.
- Seeking dental care is essential if a cavity forms; dentists can clean and fill cavities.
Preventing Cavities
- Regular brushing of teeth twice daily (morning and night) is vital.
- Dental floss is effective for cleaning between teeth.
- Rinse or wash mouth after meals to minimize food debris.
- Limit sweets and cola consumption to lower the risk of cavities.
- Bacteria, single-celled microorganisms invisible to the naked eye, play a major role in tooth decay.
