Root canal treatment is designed to relieve pain, so it can be worrying if a tooth still feels sore afterwards. Some tenderness is a normal part of healing, especially when the tooth was very inflamed or infected before treatment. However, certain types of pain suggest that the tooth needs to be checked again.
After root canal treatment, it is common for the tooth to feel tender when you bite, especially for the first few days. The tissues around the root tip may be inflamed from the infection and from the cleaning process. This discomfort usually improves day by day and responds well to over-the-counter pain relief taken as advised. Chewing on the other side and choosing softer foods helps.
If the temporary filling is slightly high, the tooth hits first when you bite, which can keep it sore. A simple adjustment by your dentist usually brings quick relief. If biting pain is the main symptom, mention this when you call the clinic.
Keeping your mouth open for a long appointment can leave the jaw muscles stiff and sore. Warm compresses and gentle jaw movements help this settle within a few days.
Contact your dentist if pain is getting worse rather than better after the first few days, if you develop swelling, fever or a bad taste, if the tooth is still very tender after a week or two, or if pain returns months later. These may indicate persistent infection, an untreated canal, a crack or a leaking filling.
Teeth can have extra canals that are difficult to find, cracks that were not visible before treatment, or infection that takes longer to resolve. Sometimes pain comes from a neighbouring tooth or from gum problems around the treated tooth. Your dentist will examine the area and take X-rays to identify the cause.
Depending on the cause, your dentist may adjust the bite, place a permanent restoration, recommend retreatment of the canals, or in some cases consider root end surgery. If a crack is found, a crown may be needed or, if the crack is severe, extraction may be the best option.
Keep the tooth clean by brushing gently and cleaning between teeth as usual. Avoid chewing hard or sticky foods on the treated side until the final restoration is placed, as the temporary filling is not designed for heavy use. Book the crown or permanent filling promptly, because a well-sealed final restoration protects the tooth from fracture and stops bacteria re-entering the canals.
Tenderness usually improves over a few days and settles within one to two weeks.
Mild tenderness is common. If it persists or the bite feels high, contact your dentist.
Occasionally, but many problems can be treated with retreatment or other options.
