Wisdom Tooth Removal: Signs You Need It and a Day-by-Day Recovery Guide
How to tell if your wisdom tooth needs to come out, what happens during removal, and exactly what to expect, and do, during recovery.
Quick answer
Most people recover from wisdom tooth removal in 3 to 5 days, with swelling peaking around day 2 or 3. For the first 24 hours, bite on gauze, rest, use cold compresses and avoid rinsing, spitting, straws and smoking. From day 2, rinse gently with warm salt water. Severe pain that gets worse after day 3 may be a dry socket.
Wisdom teeth are the last molars to come through, usually between the ages of 17 and 25. Many jaws don't have enough room for them, so they get stuck (impacted) or come through at an angle.
Not every wisdom tooth needs to be removed. But when one causes problems, removing it usually brings fast relief.
Signs your wisdom tooth may need to come out
- Pain or swelling at the back of the jaw
- Gum that is red, swollen or bleeding over a partly erupted tooth
- A bad taste or smell from the back of the mouth
- Difficulty opening your mouth fully
- Repeated food trapping and infection (pericoronitis)
- Decay in the wisdom tooth or the tooth next to it
- Crowding or damage to neighbouring teeth seen on an X-ray
Do all wisdom teeth need removing?
No. A wisdom tooth that has come through fully, sits in a healthy position and can be cleaned properly can usually stay. Our oral surgeon recommends removal only when there's a clear reason, based on your symptoms and an X-ray.
What happens during wisdom tooth removal?
- Assessment: examination and an X-ray to see the tooth's position and roots.
- Numbing: local anaesthetic, so you feel pressure but not pain.
- Removal: a simple extraction for teeth that have come through, or a small surgical procedure for impacted teeth.
- Closing: sometimes a few stitches, then gauze to bite on.
Most procedures take between 20 and 60 minutes.
Recovery timeline: day by day
| Time | What to expect | What to do |
|---|---|---|
| First 24 hours | Some bleeding, numbness wearing off, mild pain | Bite on gauze, rest, cold compress 15 min on/off, soft cool food |
| Days 2–3 | Swelling and stiffness peak | Warm salt-water rinses after meals, painkillers as advised |
| Days 4–5 | Swelling goes down, most people back to normal routine | Keep the area clean, slowly return to normal food |
| Week 1–2 | Stitches dissolve or are removed | Follow-up check if advised |
| Weeks 3–4 | Gum closes over the socket | Normal brushing everywhere |
Do's and don'ts for the first 72 hours
Do:
- Keep your head raised when lying down
- Eat soft food: yoghurt, soup (not too hot), mashed potato, eggs
- Drink plenty of water
- Take painkillers as directed by the dentist
Don't:
- Rinse, spit forcefully or use a straw for 24 hours. This can dislodge the blood clot.
- Smoke or vape. It greatly increases the risk of dry socket.
- Eat crunchy, spicy or very hot food
- Do strenuous exercise for 2–3 days
What is dry socket?
Dry socket happens when the blood clot in the socket is lost too early, exposing the bone. It typically starts 2 to 4 days after the extraction with severe, throbbing pain that may spread to the ear, and often a bad taste. If your pain gets worse instead of better after day 3, call your dentist. It's easy to treat with a medicated dressing.
Frequently asked questions
How long does wisdom tooth removal take to heal?
Most people feel normal within 3 to 5 days. The gum takes about 3 to 4 weeks to close fully, and the bone underneath takes a few months.
When can I eat normally after wisdom tooth removal?
Stick to soft food for the first 3 days, then return to normal food gradually over a week as comfort allows.
Is wisdom tooth removal painful?
The procedure is done under local anaesthesia, so it shouldn't hurt. Soreness afterwards is normal and usually well controlled with standard painkillers.
Can I go to work the next day?
Many people return to desk work after 1 to 2 days. If your job is physical, plan for 2 to 3 days off. Our doctors can provide a medical certificate if needed.
