01
Is Pain After Root Canal Treatment Normal?
Yes — mild to moderate pain is entirely normal. During root canal treatment the tissues at the root tip are cleaned and shaped. This produces a transient inflammatory response in the surrounding periodontal ligament.
In our clinical experience, around 80% of patients feel only mild tenderness afterwards, while 15–20% need painkillers for a few days.

Recovery Timeline
| Time Frame | What to Expect | What to Do |
|---|---|---|
| First 6 hours | Anaesthesia wearing off, mild throbbing | Normal — do not eat yet |
| 24–48 hours | Most intense period, pressure sensation | Take an analgesic |
| 3–5 days | Tenderness easing | Return to normal activities |
| 1 week | Most patients are pain-free | Follow-up appointment |
| 2 weeks+ | Complete healing | Crown can be planned |
03
How to Reduce the Pain
Medication
- Ibuprofen (400–600 mg): Reduces pain and swelling through its anti-inflammatory action
- Paracetamol (500 mg): An alternative if you cannot take ibuprofen
- Take at the dose recommended by your dentist, after meals
- Tip: Take the first dose before the anaesthesia wears off — it is easier to prevent pain than to treat it once it starts
Home Measures
- Salt-water rinse (warm water + 1 teaspoon of salt, three times a day)
- Cold compress (15 minutes on the cheek, 15 minutes off)
- Avoid chewing on the treated side
- Choose soft foods (soup, yoghurt, pasta)
What to Avoid
- Very hot or very cold foods
- Hard, crunchy foods
- Putting pressure on the treated tooth
- Placing aspirin directly on the tooth (causes chemical burns)
04
When Should You See Your Dentist?
The following symptoms are not normal and you should contact your dentist:
- Pain lasting longer than a week — healing is slower than expected
- Pain that is increasing — pain should be easing, not worsening
- Swelling has developed — this can indicate infection
- Fever — risk of systemic infection
- The tooth feels broken — the temporary filling may have come out
- Painkillers are no longer working — there may be an underlying problem
- Severe pain on biting — the filling may be high and need adjusting
05
Possible Causes of the Pain
| Cause | Symptom | Solution |
|---|---|---|
| Normal healing response | Mild throbbing for 3–5 days | Painkillers |
| High filling | Pain when biting | Dentist adjusts the filling |
| Residual infection at the root tip | Pain not easing | Retreatment or apicoectomy |
| Missed canal | Pain does not go away at all | Repeat root canal treatment |
| Vertical root fracture | Sharp pain when chewing | Extraction may be required |
| Problem in a neighbouring tooth | Pain felt on the wrong tooth | Examination |
06
What If Root Canal Treatment Fails?
Root canal treatment has a success rate of 90–95%. In the rare cases where it fails:
- Retreatment — the old filling is removed and the canals are recleaned
- Apicoectomy — the root tip is cleaned surgically and the infected tissue removed
- Extraction and implant — as a last resort (implant options)

What to Do After Root Canal Treatment — Detailed Guide
Diet Guide
| Period | Recommended | Avoid |
|---|---|---|
| First 2–3 hours | Nothing (anaesthesia still in effect) | Everything |
| First day | Lukewarm soup, yoghurt, milk pudding | Hot, hard, sticky foods |
| 2–3 days | Soft foods, eggs, rice | Chewing on the treated side |
| After 1 week | Normal diet | Very hard foods (until the crown is placed) |
Medication Guide
- Ibuprofen (400 mg): Every 6–8 hours, after food. Both an analgesic and an anti-inflammatory
- Paracetamol (500–1000 mg): Every 4–6 hours. An alternative if ibuprofen is not suitable
- Antibiotics: Only if prescribed by your dentist. They are indicated when there are signs of infection (swelling, fever)
- Mouthwash: Chlorhexidine or salt water — to maintain hygiene after treatment
Points to Watch
- Do not chew hard food on the treated tooth (the risk of fracture is high until a crown is placed)
- Avoid smoking and alcohol (they slow healing)
- Take prescribed medication regularly and complete the full course
- Do not delay placement of the crown (recommended within 2–4 weeks)
- Maintain regular oral hygiene (use a soft brush)
