Nobody wants surgery in their mouth, and if you’ve been told you need it, one of the first questions you’ll have is: what could go wrong?
It’s a fair question, and you deserve a straight answer. Surgical tooth extraction in Dreghorn is a common, well-established procedure — but like any clinical intervention, it carries risks, and we think patients are better served by knowing what those are upfront rather than being given vague reassurances before they sign the consent form.
Why Surgical Extraction Is Different from a Simple One
A straightforward extraction means the dentist grips the tooth with forceps and removes it in one piece. Simple enough. Surgical extraction is required when that’s not possible — when a tooth is impacted, partially erupted, broken at the gumline, or has unusually curved roots that make it impossible to remove without cutting into the tissue.
The surgical approach involves making a small incision in the gum, sometimes removing a small amount of bone, and extracting the tooth in sections if needed. The wound is then sutured closed. It’s more involved, which is precisely why the risk profile is slightly higher than a routine pull.
That said, “higher risk” is relative. In our experience, the vast majority of patients come through surgical extractions without any significant complications at all.
The Most Common Risks
Let’s go through the realistic risks — not to alarm you, but because informed patients are better patients.
- Dry socket is the one you’ll probably read the most about online. It occurs when the blood clot that forms in the socket after extraction is dislodged or dissolves before the wound has properly healed. The result is an exposed bone that’s extremely painful — a dull, aching throb that radiates to the jaw and ear. It’s more common after surgical extractions than simple ones. We’ll cover dry socket in detail in a separate article, but the short version is: it’s treatable, and there’s quite a lot you can do to avoid it.
- Infection is a risk with any surgical procedure. After extraction, bacteria can enter the socket and cause localised infection, characterised by increasing pain, swelling, and sometimes a bad taste or smell from the area. In our experience, following post-operative care instructions closely reduces this risk significantly. We’ll prescribe antibiotics when appropriate.
- Bleeding is expected immediately after any extraction — you’ll bite down on gauze for at least 30 minutes to help the clot form. Prolonged bleeding beyond a couple of hours is uncommon, but it can happen, particularly in patients on blood-thinning medications. If you’re taking warfarin, clopidogrel, or similar, tell us before the procedure. We’ll plan accordingly.
- Swelling and bruising are normal. Not a complication exactly — more of an expected consequence of surgical work in the tissues. For some patients it’s minimal; for others it’s quite pronounced, peaking around 48 hours after the procedure. Ice packs in the first 24 hours help considerably.
- Nerve damage is the risk that tends to cause the most anxiety when people read about surgical extractions, particularly lower wisdom tooth removal. The inferior alveolar nerve and the lingual nerve both run in close proximity to lower wisdom teeth. In rare cases, these nerves can be bruised or, very rarely, damaged during extraction. This can cause numbness or tingling in the lower lip, chin, tongue, or cheek. In the vast majority of cases, if there is any nerve involvement, it’s temporary and resolves within weeks to months. Permanent nerve damage is rare — but it exists, and you should be aware of it.
- Sinus involvement is a specific risk with upper molar extractions. The roots of upper back teeth sometimes extend close to, or occasionally into, the maxillary sinus. Extraction can, in rare cases, create a communication between the mouth and the sinus. This is called an oroantral communication and, if it occurs, requires prompt treatment. We always review your X-rays carefully before any upper molar extraction precisely to assess this risk.
Risks That Are Less Talked About
A couple of less common but worth-knowing risks:
- Root fracture — sometimes a root tip breaks during extraction. This is more likely with older, brittle teeth. We’ll always attempt to retrieve it, though in some cases a very small fragment can be left in situ if removal would involve more trauma than benefit.
- Adjacent tooth damage — the instruments used in surgical extraction require leverage, and in very rare cases this can affect a neighbouring tooth. It’s uncommon with careful technique, but it’s in the consent form for a reason.
- Trismus — jaw stiffness or difficulty opening the mouth wide, usually temporary, often occurs after lower wisdom tooth removal in particular.
- Delayed healing — some patients, especially those who smoke, have uncontrolled diabetes, or are on certain medications like bisphosphonates, are at higher risk of poor wound healing after oral surgery.
Actually, smoking is probably the single biggest modifiable risk factor for post-extraction complications. If you smoke, stopping even for a few days before and after the procedure makes a real difference to your healing.
How We Assess and Manage Risk
Before any surgical extraction, we take a thorough medical history, review your medications, and take appropriate X-rays — often a periapical film, and in some cases a cone beam CT scan for more complex cases. This isn’t box-ticking. It’s how we identify risks before they become problems.
We had a patient a couple of years ago who mentioned almost in passing, as we were about to start, that they’d recently been put on a bisphosphonate medication for osteoporosis. We stopped the appointment and had a proper conversation. Bisphosphonates carry a small but real risk of osteonecrosis of the jaw — a condition where the bone in that area fails to heal properly after surgical trauma. It’s rare, but it changes the risk calculation entirely, and it’s the sort of thing that needs to be planned around, not discovered after the fact.
Look, most people who have surgical extractions are fine. The risks we’ve outlined above are real, but the majority of patients experience none of them, or at most some temporary swelling and discomfort. The clinical risk is manageable. What tends to make it less manageable is when patients don’t tell us about their medications, or ignore post-operative instructions, or return to normal activity too quickly.
What the Research Says
According to NHS Inform, dental extractions — including surgical ones — are one of the most routinely performed procedures in dentistry. Serious complications are uncommon in otherwise healthy patients treated by appropriately trained clinicians. The evidence base for current surgical techniques is well-established, and the protocols we follow reflect current best practice guidance from the British Dental Association.
The risks associated with not having a necessary extraction — persistent infection, spread of bacteria, damage to adjacent teeth, impact on overall health — frequently outweigh the risks of the procedure itself. But we’ll come to that in a separate article.
A Risk Summary Table
| Risk | How Common | Usually Temporary? | Main Prevention |
|---|---|---|---|
| Dry socket | Relatively common after surgical extraction | Yes — resolves with treatment | No smoking, no straws, soft diet |
| Infection | Uncommon with good aftercare | Yes | Following post-op instructions, antibiotics if prescribed |
| Swelling/bruising | Very common — expected | Yes — peaks at 48 hours | Ice packs, rest |
| Prolonged bleeding | Uncommon | Yes | Gauze pressure, avoid blood thinners if possible |
| Nerve involvement | Uncommon; higher with lower wisdom teeth | Usually yes | Pre-op imaging, careful technique |
| Sinus communication | Rare | With prompt treatment, yes | Pre-op X-ray assessment |
| Osteonecrosis | Very rare; mainly bisphosphonate patients | No — requires management | Disclose medications in full |
Should You Be Worried?
In our experience, patients who go into surgical extraction knowing what to expect — including what could go wrong and how they can reduce that risk — do better than patients who’ve been told “it’ll be fine, nothing to worry about.”
We’re not trying to alarm you. But you’re an adult, and you deserve the full picture. Actually, the most common cause of problems after surgical extraction isn’t the procedure itself. It’s patients doing things they’ve been told not to do — smoking, rinsing vigorously on the day of surgery, eating hard food too soon, prodding the socket with their tongue. The post-operative instructions we give you aren’t suggestions.
