Human Tooth Anatomy Quiz

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.
