Pulp
Consists of connective tissue, blood vessels, and nerves. It nourishes the tooth and provides sensation.
Maxilla
Upper jawbone which supports the upper teeth and is involved in the formation of the orbit, nasal cavity, and palate.
Orthodontics
A field of dentistry that focuses on diagnosing, preventing, and correcting malpositioned teeth and jaws.
Soft Palate
Flexible part of the palate that closes off the nasal passages during swallowing.
Wisdom teeth
Also known as third molars, these are the last teeth to erupt and are often extracted due to lack of space or misalignment.
Premolars
Function to crush and grind food. Have two or more cusps.
Periodontitis
Advanced gum disease which can lead to destruction of the periodontal ligament and alveolar bone, ultimately resulting in tooth loss.
Gingiva
Gum tissue that covers the alveolar bone and surrounds the teeth to provide a seal against bacteria.
Fluoride
A mineral that helps prevent caries by promoting the remineralization of enamel and inhibiting bacterial growth.
Tongue
Essential for chewing, swallowing, tasting, and speaking. It assists in cleaning the teeth.
Canines
Used for gripping and tearing food. They have a single pointed cusp.
Enamel
Protects tooth from wear and decay. It is the hardest substance in the body.
Dental Implant
A titanium post that is surgically placed into the jawbone beneath the gum to replace the root of a missing tooth and support a crown.
Periodontal Ligament
Connects the cementum to the alveolar bone, cushioning the tooth and allowing slight movement.
Temporomandibular Joint (TMJ)
Connects the jawbone to the skull, allowing for mouth opening and movements necessary for chewing and speaking.
Molars
Best suited for grinding food, thanks to their broad and flat surfaces.
Root Canal Therapy
Dental procedure to treat infection at the centre of a tooth. It involves the removal of the tooth's pulp and filling of the root canal.
Uvula
Aids in speech and swallowing, and plays a role in keeping the mouth and throat moist.
Hard Palate
Provides structure and support for the upper part of the oral cavity and is important for speech.
Mandible
Lower jawbone which supports the lower teeth and provides attachment for muscles of mastication.
Caries
Also known as tooth decay, a bacterial infection that causes demineralization and destruction of the tooth structure.
Veneers
Thin custom-made shells designed to cover the front surface of teeth to improve appearance by altering color, shape, size, or length.
Dentin
A yellow tissue that makes up most of the tooth structure. It is hard but porous.
Alveolar Bone
Forms the sockets for the teeth, providing them with support and stability.
Cementum
Helps to secure the tooth within the jawbone. It is a calcified tissue covering the tooth's roots.
Gingivitis
Inflammation of the gums often caused by plaque build-up. It is reversible with proper oral hygiene.
Incisors
Designed for cutting and shearing food. Essential for biting into food.
Ameloblasts
Cells responsible for enamel formation during tooth development. They are lost after tooth eruption.
Plaque
A sticky biofilm that forms on teeth, which can lead to tooth decay and gum disease. Preventable with regular brushing and flossing.
Sealants
A protective plastic coating applied to the biting surfaces of back teeth to prevent cavities in pits and fissures.
Salivary Glands
Produce saliva which begins the process of digestion, maintains oral health, and lubricates the mouth.
Odontoblasts
Cells that are responsible for dentin formation and can react to stimuli such as cavities.
Dental Bridge
A fixed dental restoration used to replace one or more missing teeth by joining an artificial tooth definitively to adjacent teeth or dental implants.
