When a tooth needs to come out, the word “extraction” covers two quite different procedures — and which one you need depends on factors that aren’t always visible until a dentist is actually examining you.
Most people assume all extractions are more or less the same thing. They’re not. A simple extraction is done on a tooth that’s fully in the mouth, structurally intact enough to grip, and has roots that allow it to be loosened and lifted out without cutting anything. A surgical tooth extraction in Dreghorn involves making an incision in the gum, sometimes removing a small amount of bone, and often sectioning the tooth into pieces before removal. The clinical gap between the two is significant — different instruments, different techniques, different recovery, and different risks.
What Makes an Extraction “Simple”?
Simple extraction works when everything lines up in your favour. The tooth needs to be fully erupted — meaning it’s broken through the gum completely and is accessible without cutting. It needs to be intact enough that we can get a secure grip with extraction forceps. And it needs to have roots that aren’t going to resist normal elevation forces: straight, single roots or well-behaved multi-rooted teeth where the roots follow a predictable path.
In those circumstances, the procedure is straightforward. An elevator instrument is used to widen the socket and loosen the periodontal ligament — the tissue that attaches tooth to bone. Then forceps are applied, the tooth is rocked gently to expand the socket further, and it’s removed. For a cooperative tooth, this can genuinely take two or three minutes once the anaesthetic is working.
But plenty of teeth don’t cooperate.
When Surgical Extraction Becomes Necessary
Surgical extraction is needed when a simple approach either can’t be attempted or carries an unacceptable risk of failure. The most common situations are:
- Impacted teeth — teeth that haven’t erupted properly and are trapped under gum or bone, most commonly lower wisdom teeth but sometimes upper canines or other teeth that failed to come through normally
- Broken or decayed to the gum line — when a tooth has so little crown left that there’s nothing for forceps to grip, the root or roots need to be accessed surgically
- Fractured roots — roots that have broken off during a previous extraction attempt, or teeth that have fractured at an awkward angle during treatment
- Hypercementosis or ankylosis — conditions where the root has fused or partially fused to the surrounding bone, making normal socket widening impossible
- Curved or divergent roots — roots with significant curvature or multiple widely-spread roots that won’t follow the path of the socket under extraction forces
- Brittle teeth — heavily restored teeth, endodontically treated (root-filled) teeth, and sometimes older teeth can be prone to fracturing under simple extraction forces, making a surgical approach safer from the start
Actually, root-filled teeth are worth flagging specifically. After root canal treatment, a tooth loses its blood supply and becomes considerably more brittle over time. In our experience, teeth that have had root canal work done years or decades ago are more likely to fracture on attempted simple extraction than teeth that haven’t — which means they often end up in surgical territory even when they look, from the outside, like they should be easy.
The Practical Differences in How Each Is Done
This is where the two approaches diverge clearly. For a simple extraction, the workflow is: anaesthesia, luxation with an elevator (loosening the tooth), forceps, removal. No cutting, no sutures, no drilling.
Surgical extraction adds several steps. A flap of gum tissue is cut and lifted away to expose the underlying bone and tooth. If bone is blocking access to the tooth, a dental drill is used to remove the minimum amount needed — the approach is always to take as little as possible. The tooth may then be sectioned into two or more pieces; this isn’t damaging, it’s actually more controlled than trying to lever a whole awkward tooth out in one movement. Once everything is out, the socket is irrigated to remove debris, and the gum flap is sutured back in place. Dissolvable stitches are standard and typically disappear within ten days.
| Feature | Simple Extraction | Surgical Extraction |
|---|---|---|
| Incision required? | No | Yes — gum flap elevated |
| Bone removal? | No | Sometimes, minimally |
| Tooth sectioning? | No | Often, especially for multi-rooted or impacted teeth |
| Sutures? | Rarely | Yes — usually dissolvable |
| Procedure time | 2–10 minutes | 15–45 minutes |
| Recovery period | 1–3 days discomfort | 3–7 days discomfort, swelling likely |
| Risk of dry socket | Lower | Slightly higher |
Does the Type of Extraction Change How Much It Hurts?
During the procedure — no. Local anaesthesia is equally effective for both. You’ll feel pressure and movement either way, but pain during the extraction itself, with proper anaesthesia, shouldn’t be an issue in either case. Look, if you feel sharp pain during any extraction, you say so and we give more anaesthetic. That’s not a sign things have gone wrong, it’s just anatomy — some areas are slower to numb than others.
Post-operatively, surgical extractions do tend to produce more discomfort than simple ones, and for longer. There’s more tissue involved: the gum has been cut, the bone may have been shaped, and the body’s inflammatory response is proportionally larger. Swelling peaks around day two or three and then settles. Ibuprofen, taken regularly for the first 48 hours rather than waiting for pain to escalate, handles most of this well.
Can You Tell in Advance Which Type You’ll Need?
Often, yes — X-rays give us a good picture of root shape, angulation, and how deep any impaction goes. But not always entirely. In our experience, even straightforward-looking teeth occasionally fracture on elevation, at which point a surgical approach becomes necessary mid-procedure. That’s not a failure; it’s just dentistry. The important thing is that we’re always prepared to adapt.
We had a patient come in expecting a quick lower molar extraction — the tooth was visible, had been giving pain, seemed like it should be simple. The X-ray showed dramatically curved roots. We explained upfront that it would need to be done surgically, and while she wasn’t thrilled about that, she appreciated knowing in advance rather than having things turn complicated halfway through.
But honestly, the distinction matters less than patients often think. Both procedures are done under local anaesthesia, both are routine in general practice, and both have high success rates when assessed and planned properly.
What Anaesthetic Is Used and How Reliable Is It?
Local anaesthetic is the standard for both simple and surgical extractions carried out in general practice. For the upper jaw, infiltration anaesthesia — injecting around the tooth roots — works reliably in most patients because the bone is porous enough for the solution to penetrate easily. The lower jaw requires a nerve block: anaesthetic is injected near the inferior alveolar nerve as it enters the mandible, numbing the entire lower quadrant on that side.
In our experience, the lower jaw is where patients most often report incomplete numbness, particularly in the molar region. This isn’t a failure of the technique — it reflects anatomy. Some patients have additional nerve supply to lower teeth that requires supplementary injections. We assess, we check, and we add more anaesthetic if needed. The procedure doesn’t begin until the area is properly numb. That’s a firm rule, not a guideline.
Sedation — whether inhaled nitrous oxide or intravenous midazolam — is available for patients with significant dental anxiety and can be discussed at the assessment stage. But for the majority of patients, a well-administered local anaesthetic is all that’s needed.
Does Surgical Extraction Always Require a Hospital Referral?
No, and this is a common misunderstanding worth clearing up. Many surgical extractions — including impacted wisdom teeth, provided they’re not in a complex anatomical position — can be carried out by a suitably trained dentist in general practice. Referral to an oral surgery unit is appropriate for cases where teeth are in very close proximity to the inferior alveolar nerve, where there are medical factors complicating the procedure, or where the case is genuinely beyond the scope of the practice. For a lot of patients, though, a hospital referral adds waiting time without adding any clinical benefit.
