Dental Anatomy Terms

Enamel

The hard, white outer layer of teeth that protects against decay. The hardest substance in the human body, but can be damaged by acid and bacteria.

Dentin

The layer beneath enamel that makes up most of the tooth structure. Contains tiny tubes that can cause sensitivity when exposed.

Pulp

The innermost part of the tooth containing nerves, blood vessels, and connective tissue. When infected, may require root canal treatment.

Crown

The visible part of the tooth above the gum line. Also refers to an artificial cap that covers a damaged tooth.

Root

The part of the tooth below the gum line that anchors the tooth in the jawbone through root canals and periodontal ligaments.

Gingiva

The gum tissue that surrounds and protects teeth and tooth roots. Healthy gums are pink, firm, and don’t bleed when brushing.

Periodontal Ligament

Connective tissue that attaches the tooth root to the socket in the jawbone, providing cushioning during chewing.

Alveolar Bone

The portion of the jawbone that contains the tooth sockets. Can be lost due to gum disease or tooth loss.

Common Dental Procedures

Prophylaxis

Professional dental cleaning to remove plaque, tartar, and stains. Typically performed every six months for optimal oral health.

Composite Restoration

Tooth-colored filling material used to repair cavities or damaged teeth. Bonds directly to tooth structure for a natural appearance.

Root Canal Therapy

Treatment to remove infected or damaged pulp tissue from inside a tooth, clean the canals, and seal them to save the tooth.

Scaling and Root Planing

Deep cleaning procedure to treat gum disease by removing plaque and tartar from below the gum line and smoothing root surfaces.

Dental Implant

Titanium post surgically placed in the jawbone to replace a missing tooth root, topped with a crown to replace the missing tooth.

Sealant

Thin plastic coating applied to the chewing surfaces of back teeth to prevent cavities in the pits and grooves.

Fluoride Treatment

Professional application of concentrated fluoride to strengthen tooth enamel and help prevent decay.

Common Dental Conditions

Caries

Tooth decay or cavities caused by bacteria that produce acid, which dissolves tooth enamel. Requires filling or other restoration.

Gingivitis

Early stage of gum disease characterized by red, swollen, bleeding gums. Reversible with proper oral hygiene and professional care.

Periodontitis

Advanced gum disease where infection spreads below the gum line, potentially causing bone loss and tooth loss if untreated.

Malocclusion

Misalignment of teeth or incorrect relation between upper and lower teeth. May require orthodontic treatment to correct.

Halitosis

Persistent bad breath often caused by bacteria in the mouth, poor oral hygiene, or underlying dental problems.

Xerostomia

Dry mouth condition where saliva production is reduced, increasing risk of cavities and gum disease.

Bruxism

Grinding or clenching of teeth, often during sleep, which can cause tooth wear, jaw pain, and headaches.

Dental Materials

Porcelain

Ceramic material used for crowns, veneers, and inlays that closely matches natural tooth color and translucency.

Amalgam

Silver-colored filling material made from mercury and metal alloys, known for durability in back teeth.

Titanium

Biocompatible metal used for dental implants because it integrates well with bone tissue.

Composite Resin

Tooth-colored plastic and glass mixture used for fillings, bonding, and cosmetic improvements.

  • Orthodontics: Specializes in straightening teeth and correcting bite problems using braces, aligners, and other appliances.
  • Periodontics: Focuses on gum disease treatment and the supporting structures of teeth including gums and bone.
  • Endodontics: Specializes in root canal therapy and treatment of tooth pulp and nerve issues.

Understanding Dental Terms

Why is understanding dental terminology important?

Understanding dental terms helps you make informed decisions about your oral health care. When you understand what procedures involve, what conditions mean, and how treatments work, you can better participate in your care and feel more confident about treatment recommendations.

What should I do if I don’t understand something my dentist says?

Always ask for clarification! Good dentists welcome questions and want you to understand your treatment. Don’t hesitate to ask for simpler explanations, written information, or visual aids to help you understand procedures or conditions better.

How can I learn more about my specific dental condition?

Start with this dictionary for basic terms, then ask your dentist for specific information about your condition. We provide educational materials, show X-rays and photos when helpful, and take time to explain your individual situation and treatment options thoroughly.
