Discover why throbbing tooth pain can persist after a root canal and learn possible causes and relief tips.
Throbbing or pulsing pain after a root canal can sometimes occur even if the pulp has been removed. One possible reason is that one of the tooth’s canals was not fully cleaned, shaped, or sealed during treatment. Bacteria or residual tissue can remain inside an untreated or partially treated canal, leading to inflammation or infection in the surrounding tissue. This can cause persistent throbbing, pressure sensitivity, and discomfort when chewing or biting.
In some cases, ongoing jaw or facial pain may also be linked to nerve conditions such as Trigeminal Neuralgia, which can closely mimic toothache symptoms. Pain from nerve irritation may be sudden, sharp, or electric shock–like and can sometimes affect multiple teeth or areas of the face. Distinguishing between dental causes and nerve-related pain often requires careful evaluation by both a dental specialist (endodontist) and a neurologist.
Proper diagnosis is important because the treatment approaches differ. While a missed canal may require retreatment or additional dental procedures, nerve-related pain may need medical management or medication. Following post-treatment care instructions, managing inflammation, and monitoring any changes in symptoms can help reduce discomfort while awaiting evaluation.
