Dental Vocabulary in English: A Complete Reference
Tooth Anatomy
Being able to point to the right tooth and describe the problem accurately saves time and reduces misunderstandings. A single tooth is tooth (plural: teeth — one of the most common English learner mistakes). Types of teeth: incisors (front cutting teeth), canines (pointed teeth either side of the incisors), premolars (transitional teeth behind the canines), molars (large flat grinding teeth at the back), wisdom teeth (third molars that emerge in adulthood, often causing problems). Tooth structure: crown (the visible part above the gum), root (the part embedded in the jawbone), enamel (hard outer coating), dentine (the layer beneath enamel), pulp (the soft inner core containing nerves and blood vessels), gum (the soft tissue around the base of teeth).
Symptoms and Complaints
Describing symptoms precisely helps the dentist diagnose faster. Core vocabulary: toothache — pain in a tooth (used as a noun: 'I have a toothache' or as an adjective: 'toothache pain'). Cavity — a hole caused by tooth decay (not 'caries', which is the clinical term). Sensitivity — discomfort when consuming hot, cold, sweet, or acidic items. Abscess — a pocket of pus caused by infection, often presenting as swelling. Swollen gum — inflamed gum tissue around a tooth. Bleeding gums — a sign of gingivitis or gum disease. Cracked tooth — a fracture in the tooth structure. Chipped tooth — a small break in the enamel. Loose tooth — a tooth with reduced support from the bone or gum.
Describing pain character: throbbing (pulsating), sharp (acute, stabbing), dull ache (constant but mild), shooting pain (pain that travels), intermittent (comes and goes).
Dental Procedures
Filling — a restoration that fills a cavity after decay is removed. Materials: composite (tooth-coloured, the standard today), amalgam (silver-coloured, older type). Root canal treatment (also root canal therapy or simply root canal) — removal of infected pulp from the root canal, followed by sealing. Despite its fearsome reputation, it is performed under local anaesthetic and should not be painful. Extraction — removal of a tooth that cannot be saved. Crown — a cap placed over a damaged tooth to restore its shape and function. Bridge — a fixed restoration that fills the gap left by a missing tooth, anchored to adjacent teeth. Implant — a titanium post surgically placed in the jawbone, onto which a crown is attached. Scale and polish — professional cleaning to remove tartar (hardened plaque) and stain. Teeth whitening — bleaching treatment to lighten tooth colour.
Anaesthesia and Anxiety
Fear of the dentist (dental anxiety or dental phobia) is very common. Key vocabulary: local anaesthetic — an injection that numbs the area being treated. Topical anaesthetic — a gel applied to the gum before the injection to reduce needle discomfort. Numb (adjective) — without sensation: 'My lip feels numb.' Sedation — a medication-induced relaxed state (not full unconsciousness). General anaesthetic — full unconsciousness, used only for complex surgical procedures.
Useful phrases: 'Can I have a local anaesthetic for this?', 'Could you apply a numbing gel before the injection?', 'Please stop if it hurts — I'll raise my hand.'
