Impacted wisdom teeth cause more problems than most people realise, and they’re one of the main reasons patients end up needing surgical tooth extraction in Dreghorn.
Let’s be clear about what “impacted” actually means, because patients hear the word and immediately assume the worst. An impacted wisdom tooth is simply one that hasn’t erupted fully into the mouth. It might be partially through the gum, lying at an angle, or entirely enclosed within the jawbone. The severity varies quite a bit, and so does what we need to do about it.
Why Wisdom Teeth Get Impacted in the First Place
Human jaws have got smaller over thousands of years. Wisdom teeth haven’t got the memo. By and large, there just isn’t enough room at the back of most adult mouths for these third molars to come through cleanly, which is why impaction is so common. Some estimates suggest that around 73% of young adults in Scotland have at least one impacted wisdom tooth, though many never cause any bother at all.
Actually, that’s worth pausing on. Not every impacted wisdom tooth needs removing.
If a wisdom tooth is fully enclosed in bone, not causing pain, not damaging the adjacent tooth, and not showing signs of infection or cyst formation, leaving it alone is often the right call. In our experience, patients sometimes come in convinced they need all four out immediately, having read something online. We’d rather see the X-rays first and have an honest conversation about what’s actually going on.
Where things get complicated is when a tooth is partially erupted. The gum flap sitting over it — called the operculum — creates a pocket that’s almost impossible to clean properly. Food debris and bacteria collect there. The result is pericoronitis, which is a painful infection of the tissue around the tooth. We see a fair number of patients in their late teens and twenties who’ve had recurring episodes of this, and at that point the tooth usually does need to come out.
What Makes It “Surgical” Rather Than a Simple Extraction
A simple extraction involves loosening and removing a tooth that’s fully above the gumline. Surgical extraction is different in scope. With an impacted wisdom tooth, we typically need to make an incision in the gum tissue, sometimes remove a small amount of bone surrounding the tooth, and in many cases divide the tooth into sections before removing it piece by piece.
That might sound alarming written down.
In practice, patients are thoroughly numbed and the procedure is far more straightforward from the patient’s perspective than it sounds. What they experience is mostly pressure, vibration, and the occasional odd sensation — not pain. The complexity is on our side of things, not theirs.
According to guidance from the Faculty of Dental Surgery at the Royal College of Surgeons, surgical removal is indicated when there is recurrent pericoronitis, adjacent tooth damage, pathological changes such as cysts, or pain that isn’t resolving. It’s not a decision we take lightly, and it’s not one you should feel rushed into either.
The Procedure Step by Step
We start with local anaesthetic. A lot of anxiety about this procedure is actually anxiety about pain during it, and the anaesthetic is the most important part of making that a non-issue. We give it time to work properly before we start anything. No rushing.
Once you’re numb, we make a small incision in the gum over and around the tooth. The flap of tissue is gently moved aside. If there’s bone covering the tooth, we remove what’s necessary to access it — usually a small amount, carefully done. We then section the tooth if needed (with lower wisdom teeth in particular, dividing them horizontally or into multiple sections makes removal much easier and causes less trauma than trying to pull a large angled tooth out in one piece).
Each section is removed with elevators and forceps. The socket is then cleaned and irrigated to remove any debris. We close the gum flap with dissolvable sutures.
The whole thing typically takes between 20 minutes and 45 minutes per tooth depending on the position, depth, and root shape. We’ll give you a more honest estimate once we’ve looked at your X-rays.
We Had a Patient Worth Telling You About
We had a patient in her mid-thirties who’d been putting off the procedure for nearly four years. Not unusual — we see this a fair bit. She’d had three separate courses of antibiotics for pericoronitis, and each time she felt better, she’d decide the extraction wasn’t necessary after all. When she finally came in, the impacted lower-right wisdom tooth had started pushing against the root of the second molar behind it, causing early root resorption. It still came out fine, and the second molar has held up, but that’s a complication that didn’t need to happen. In our experience, delaying rarely makes things better and sometimes makes them meaningfully worse.
What to Expect Immediately After
The anaesthetic wears off over an hour or two. You’ll want to have painkillers ready for when it does. Ibuprofen works better than paracetamol for post-surgical dental pain in most patients, and the two can be alternated if needed. That said, follow whatever your dentist has recommended rather than what you’ve read here, because individual health factors matter.
Bleeding for the first hour is normal. The clot that forms in the socket is important — don’t dislodge it. Soft foods, no straws, no smoking, avoid prodding the area with your tongue. We’ll go through all of this with you before you leave.
Swelling typically peaks at 48 to 72 hours. An ice pack on the face in the first few hours helps. After 48 hours, warmth is more useful than cold for resolving swelling.
| Day | What to Expect | What to Do |
|---|---|---|
| Day 1 | Bleeding, numbness fading, mild discomfort | Bite on gauze, rest, soft food only, no rinsing |
| Days 2–3 | Peak swelling, aching, possible bruising | Alternate ibuprofen/paracetamol, ice then warmth |
| Days 4–5 | Swelling reducing, socket tender | Gentle salt water rinse from day 2 or 3 |
| Days 6–7 | Most patients significantly improved | Soft but more varied diet, gentle brushing near site |
| Week 2+ | Near normal for most patients | Sutures dissolve, return to normal eating gradually |
Dry Socket and Other Complications
The most talked-about complication is dry socket — technically called alveolar osteitis. It happens when the blood clot in the socket breaks down or dislodges before the tissue has healed properly, leaving the bone exposed. It’s not dangerous, but it is genuinely painful, typically presenting as a deep aching pain starting a few days after extraction.
Look, smoking is the biggest risk factor by some margin. Patients who smoke after an extraction have a significantly higher rate of dry socket. We always advise against it and we’re always ignored by some people. At least give it 24 hours.
Nerve tingling or numbness after lower wisdom tooth extraction is worth mentioning too, because it worries people when it happens. The inferior alveolar nerve runs very close to the roots of lower wisdom teeth, and it can sometimes be temporarily affected. Permanent nerve damage is uncommon but is a risk that should be explained before surgery — we discuss this at your consultation so there are no surprises.
