Dental Anatomy
View all
The anatomy of a tooth includes the crown (the visible part above the gums), the neck (the middle section at the gumline), and the root (the part below the gums that anchors the tooth). The main layers are enamel (the hard outer layer), dentin (the bulk of the tooth beneath the enamel), and pulp (the inner soft tissue with nerves and blood vessels).
Parts of the tooth
- Crown: The visible part of the tooth above the gumline, covered in enamel.
- Neck: The narrow part of the tooth at the gumline, where the crown meets the root.
- Root: The part embedded in the jawbone that anchors the tooth. It is covered by cementum and contains the root canal.
Layers of the tooth
- Cementum: A bone-like layer that covers the root of the tooth, helping to anchor it to the jaw.
- Enamel: The extremely hard, protective outer layer of the crown.
- Dentin: The layer beneath the enamel that makes up the main body of the tooth.
- Pulp: The innermost part of the tooth, containing nerves, blood vessels, and connective tissue. It extends from the crown's pulp chamber to the tip of the root via the root canal.
Types of teeth
- Incisors: The front teeth used for biting.
- Canines: The pointed teeth next to the incisors, used for tearing food.
- Premolars (or bicuspids): Teeth located behind the canines that are used for grinding and crushing food.
- Molars: The large teeth at the back of the mouth are used for heavy grinding and crushing.
Dental Scaling Procedure
A dental scaling procedure removes plaque and tartar (calculus) from teeth, using ultrasonic tools or hand scalers to clean above and below the gumline, often followed by root planing (smoothing roots) for gum disease. It's a deep cleaning that prevents decay and gum disease, sometimes requiring a local anesthetic for comfort, and ends with polishing to make teeth smooth and resistant to future buildup.
What happens during the procedure:
- Examination: The dentist first checks for tartar buildup to determine the extent of cleaning needed.
- Numbing (if needed): A topical gel or local anesthetic is applied to numb the gums, especially for deep cleanings (scaling & root planing).
- Scaling:
- Ultrasonic scaler: A vibrating metal tip uses high-pressure water to break up and flush away deposits.
- Hand scalers: Small, hook-shaped instruments manually scrape off stubborn plaque and tartar.
- Root planing (for deep cleaning): After scaling, the roots are smoothed to help gums reattach to the teeth and prevent bacteria from gathering.
- Polishing: A rotating brush with cleaning paste or an air-powder spray smooths the tooth surfaces, removing stains and making them harder for plaque to stick to.
When it's done:
- Regular cleaning (prophylaxis): For healthy gums, above the gumline.
- Deep cleaning (Scaling & Root Planing - SRP): For gum disease (periodontitis) to clean deep pockets below the gumline.
Key benefits:
- Removes bacteria that cause gum disease (gingivitis, periodontitis).
- Stops gum disease from progressing, reducing bleeding, swelling, and bad breath.
- Leaves teeth feeling smooth, clean, and glossy.
