Study Notes
Structure and Importance of Teeth
- Teeth are essential for biting, chewing food, and shaping the face.
- They contribute to clear speech and enhance the beauty of smiles.
- Primary teeth, also known as milk teeth, emerge around six months and total twenty by age two.
Tooth Anatomy
- Three main parts of a tooth: crown (visible part), neck (meets the root), and root (below the gum).
- Enamel: The outermost, hard layer of a tooth that protects against wear.
- Dentine: Beneath enamel, providing structure.
- Pulp: Soft inner part containing nerves and blood vessels for nutrition.
Types of Teeth
- Incisors (8 total): Sharp, used for cutting food; four in upper jaw, four in lower.
- Canines (4 total): Pointed teeth for tearing food; two in each jaw.
- Premolars (8 total): Broad and flat, help with cracking food; four in each jaw.
- Molars (12 total): Broad teeth for grinding and chewing; six in each jaw.
Tooth Decay
- Food particles can trap between teeth, leading to bacterial growth.
- Bacteria form plaque, which produces acid causing enamel decay and cavities.
- Permanent teeth replace milk teeth by age six, with adults possessing 32 teeth.
Dental Care and Hygiene
- Important to brush teeth after meals or at least twice daily.
- Use dental floss to clean between teeth, and gargle after meals.
- Avoid excessive sweets; maintain a balanced diet for strong teeth.
- Regular dental check-ups are recommended every six months.
Microbes Overview
- Microbes are microscopic organisms found in various environments: air, water, soil, and within bodies.
- They can aid in food production (e.g., yogurt) and animal digestion.
- Some microbes cause diseases like typhoid and pneumonia.
- Growth of microbes is facilitated by warmth, moisture, food, and air.
Structure of a Tooth
- A tooth comprises three main parts: the crown (visible part), neck (connects crown to root), and root (embedded in gum).
- The outer layer, known as enamel, protects the tooth and is the hardest substance in the body.
- Beneath the enamel is dentine, followed by the pulp, containing nerves and blood vessels providing nutrition to the tooth.
Development of Teeth
- Baby teeth, or milk teeth, begin to appear around six months old, totaling twenty by age two.
- At approximately six years old, milk teeth are replaced by permanent teeth.
- An adult has 32 teeth, 16 in the upper jaw and 16 in the lower jaw.
Types of Teeth
- Incisors: Cutting teeth located at the front, with sharp edges; there are eight in total.
- Canines: Pointed, tearing teeth found next to incisors; there are four in total.
- Premolars: Positioned next to canines, broader and used for crushing; there are eight total.
- Molars: Located at the back for grinding food; adults have twelve molars.
Tooth Decay
- Tooth decay occurs when food particles are trapped between teeth, leading to bacteria growth, plaque formation, and cavities.
- Decay can expose the pulp, resulting in pain and potential tooth loss.
Care of Teeth
- Brushing teeth twice daily is crucial; employing correct strokes (down for upper teeth, up for lower teeth) and rinsing after meals is recommended.
- Regular dental check-ups (every six months) and proper diet can help maintain dental health.
- Avoid excessive sweets, extreme temperatures in food, and ensure a balanced diet for strong teeth.
Overview of Microbes
- Microbes are microscopic organisms found in various environments, essential for processes like digestion and food fermentation.
- There are four main types: bacteria, fungi, protozoa, and viruses.
- Many microbes are helpful (e.g., producing yogurt), while others can cause diseases (e.g., typhoid, malaria).
Types of Microbes
- Bacteria: Single-celled and can be beneficial or pathogenic; contribute to decomposition and some disease causation.
- Fungi: Non-green microorganisms that can cause skin conditions and are used in food production.
- Protozoa: Single-celled organisms sometimes responsible for diseases like dysentery.
- Viruses: The smallest type of microbe, causing various illnesses, including the common cold and influenza.
Structure of a Tooth
- A tooth comprises three main parts: the crown (visible part), neck (connects crown to root), and root (embedded in gum).
