Why can a tooth feel sore afterwards?
The pulp is removed during treatment, but the ligament and bone around the root remain living tissues. Pre-existing inflammation and temporary irritation of these tissues can make the tooth feel different for a time.
- Inflammation around the root before treatment
- Temporary tenderness to chewing pressure
- A temporary restoration that feels high in the bite
- Healing of the surrounding tissues
How long can sensitivity last?
Mild to moderate sensitivity may be present during the first few days and should generally reduce over time. Increasing pain, pain that is not clearly improving or discomfort affecting daily life should be discussed with the treating dentist.
When should you contact the clinic?
Seek prompt advice if pain is increasing, there is visible swelling, fever, a high bite or the temporary restoration is lost. Rapidly spreading swelling, difficulty swallowing or difficulty breathing requires urgent medical assessment.
- Increasing or severe persistent pain
- Visible swelling in the mouth or face
- Fever or a marked change in general health
- The tooth feels clearly high when biting
- Rash, itching or another possible allergic reaction after medication
Does pain mean treatment has failed?
No. Early sensitivity that reduces with time is not, by itself, evidence of failure. The result is assessed using symptoms, clinical examination and radiographic follow-up when indicated.
Is discomfort possible on the same day?
Yes. Sensitivity can be felt after local anaesthesia wears off. Its progression and any additional signs matter.
Does every episode of pain require antibiotics?
No. Pain alone is not an indication for antibiotics. The decision depends on clinical findings and general health.
