Toothache is discomfort felt in a tooth, the surrounding tissues, or radiating into the jaw and face. This page outlines likely causes, what patterns of pain can indicate, when prompt assessment is needed, and which dental specialists may become involved. It does not replace clinical examination or professional diagnosis.
Common causes of toothache
Frequent sources of dental pain include cavities that reach the dentine or pulp, inflamed pulp (pulpitis), gum and periodontal infections, dental abscesses, cracked teeth, and problems with fillings or restorations. Pain can also stem from referred sources such as jaw joint (TMJ) issues or nerve-related facial pain.
What different pain types may mean
Sharp, brief pain on biting or when exposed to cold often indicates a crack or dentine sensitivity. Throbbing or persistent severe pain that worsens at night may suggest pulp inflammation or an abscess. Pain triggered by hot or lingering temperature sensitivity commonly points to deeper tooth or pulp involvement. Pain radiating to the ear, temple or jaw can mean nearby structures or nerves are affected and merits evaluation.
When to seek urgent evaluation
Seek prompt assessment if you have pronounced facial swelling, difficulty breathing or swallowing, high fever, visible abscess, or severe pain that does not ease—these can signal spreading infection or a complication requiring urgent care. For non-urgent but persistent or recurring pain, arrange a dental appointment to identify the cause and next steps.
Which specialists can help and referral pathways
Start with a general dentist for diagnosis and initial management. Endodontists focus on root canal and pulp problems; oral and maxillofacial surgeons handle surgical extractions and deep infections; periodontists treat advanced gum disease. Pediatric dentists (pedodontists) manage tooth pain in children, and if pain involves the ear or facial nerves, ENT or maxillofacial specialists may be consulted.
Prevention and everyday oral care
Regular dental check-ups, correct brushing and interdental cleaning, fluoride use as advised by your dentist, and limiting frequent sugary snacks reduce risk of decay and pain. Smoking and some habits increase periodontal risk—addressing these factors supports long-term oral health.
