Amalgam is a dental filling material made from a mixture of metals, including silver, tin, copper, and mercury. It is strong and long-lasting. An example is the use of amalgam fillings for restoring decayed teeth.

Anesthesia

Anesthesia is a medication or numbing agent used to block pain and sensation during dental procedures. For instance, local anesthesia is commonly administered with a needle to numb a specific area before a filling.

Anterior

Anterior refers to the front teeth in the mouth. These include the incisors and canines. For example, a dentist may perform cosmetic procedures on anterior teeth to improve their appearance.

Apex

The apex is the tip or end of a tooth’s root. It is a critical part for root canal treatment. For example, during a root canal procedure, the dentist removes the infected tissue from the apex of the tooth’s root.

Arch

An arch in dentistry refers to the curved arrangement of teeth in the upper or lower jaw. For example, orthodontic treatments like braces are used to align teeth within the dental arch.

Attrition

Attrition is the gradual loss of tooth structure due to normal wear and tear from chewing and grinding. It can result in tooth flattening over time. For example, attrition may cause sensitivity and the need for dental restorations.

Bicuspid

Bicuspids are the premolar teeth located between the molars and canines. They have two cusps (points). For example, bicuspids are used for chewing and grinding food.

Biopsy

A biopsy involves the removal of a small piece of tissue for examination. In dentistry, it may be performed to diagnose oral lesions or abnormalities. For instance, a dentist may perform an oral biopsy if there are suspicious lesions in the mouth.

Braces

Braces are orthodontic appliances used to straighten and align teeth. They consist of brackets, wires, and bands. For example, a teenager might get braces to correct a misaligned bite.

Bridge

A dental bridge is a fixed prosthetic device used to replace one or more missing teeth. It is anchored to adjacent teeth or implants. For example, a bridge can restore a gap left by a missing tooth.

Canker Sore

A canker sore, or aphthous ulcer, is a painful sore or lesion that can develop inside the mouth. They are usually small, round, and white or gray with a red border. For instance, a canker sore can cause discomfort while eating or speaking.

A dental crown is a tooth-shaped cap that covers and protects a damaged or weakened tooth. It can also improve the appearance of a tooth. For example, a crown is placed over a tooth following a root canal or after significant tooth decay.

Cusp

The cusp is a pointed or raised part of a tooth used for biting and tearing food. Molars typically have multiple cusps. For example, molars have cusps that help with chewing and grinding food.

Deciduous Teeth

Deciduous teeth, often referred to as baby teeth or primary teeth, are the first set of teeth that erupt in childhood. They eventually fall out to make way for permanent teeth. For example, a child’s deciduous teeth will start to shed as they grow.

Dentin

Dentin is the hard tissue underlying the enamel in a tooth. It is less dense than enamel and can transmit sensations. For example, dentin can become exposed when enamel wears away, leading to tooth sensitivity.

Denture

A denture is a removable dental prosthesis that replaces missing teeth and surrounding tissues. There are partial and complete dentures. For example, complete dentures are used when all teeth are missing in one or both arches.

Enamel

Enamel is the outermost layer of a tooth, and it is the hardest and most mineralized substance in the human body. It provides protection and strength to the tooth. For example, enamel can erode due to acidic foods and beverages.

Endodontics

Endodontics is a dental specialty that focuses on the diagnosis and treatment of diseases and conditions within the tooth’s pulp and root canal system. For example, endodontists perform root canal therapy to save damaged teeth.

Extraction

Tooth extraction is the removal of a tooth from its socket in the jawbone. It is typically done when a tooth is beyond repair or causing issues. For example, a wisdom tooth extraction may be necessary if it’s impacted.

Filling

A dental filling is a material used to restore a decayed or damaged tooth. Common filling materials include amalgam, composite resin, and porcelain. For example, a dentist may place a filling in a cavity to repair the tooth.
