Why wisdom teeth cause so much trouble
Wisdom teeth — the third molars — erupt last, usually between the late teens and mid-twenties, into whatever space is left at the back of the jaw. Often there isn't enough. A wisdom tooth blocked from erupting fully is 'impacted': it may lie tilted against the tooth in front, partly through the gum, or fully buried. Some people's wisdom teeth erupt cleanly and behave for life; some people never develop them at all. The trouble belongs almost entirely to the partly erupted and the awkwardly angled.
Pericoronitis — the classic wisdom tooth pain
A partly erupted wisdom tooth sits under a flap of gum that traps food and bacteria and is impossible to clean properly. The recurring infection of that flap — pericoronitis — is the signature wisdom tooth complaint: a swollen, sore gum at the back corner of the mouth, pain on biting (often because the opposing tooth bites the swollen flap), a bad taste, and in worse episodes restricted mouth opening and swelling toward the jaw or throat.
Mild episodes settle with meticulous cleaning of the area, warm salt-water rinses and pain relief. Worsening swelling, fever, difficulty swallowing or trismus (struggling to open your mouth) mean the infection is spreading — that is a same-day call to us on 01282 965286, not a wait-and-see. Same-day emergency appointments are from £90.
When removal is genuinely justified — and when it isn't
UK practice follows NICE guidance: wisdom teeth are not removed simply for existing. Removal is justified by disease or recurring trouble — repeated pericoronitis, decay in the wisdom tooth or the tooth in front (a common casualty, because the impaction traps plaque against it), abscess, cyst formation around a buried tooth, or damage to the neighbouring molar. A symptom-free, disease-free buried wisdom tooth is generally left alone and monitored. If a dentist recommends removing trouble-free wisdom teeth 'preventively', it is reasonable to ask which of these criteria applies — and you can expect us to volunteer that answer with the X-ray on screen.
What assessment involves
An examination and an X-ray showing the whole tooth: its angle, its depth, the shape of its roots, and — for lower wisdom teeth — its relationship to the nerve canal that runs through the lower jaw carrying sensation to the lip and chin. That relationship determines both the difficulty of removal and the conversation we must have about nerve risk. Where a lower tooth wraps the nerve closely, options include specialist referral or removing the crown of the tooth while deliberately leaving the roots (coronectomy) to keep the nerve safe.
What removal actually involves
Upper wisdom teeth are usually straightforward and quick. Lower impacted teeth take more doing: local anaesthetic, sometimes a small gum incision, occasionally removal of a little bone or sectioning the tooth to lift it out in pieces — which sounds dramatic and is in practice a gentler approach than forcing a whole awkward tooth. You feel pressure and vibration, not pain. Extractions at Station House are from £144.50 with the price confirmed in writing after assessment, and complex surgical cases are referred where that is the safer route.
Recovery — realistic expectations
Expect the worst swelling and stiffness at days two to three, then steady improvement across the week; bruising along the jaw is possible and harmless. The aftercare rules are the same ones that protect any extraction: guard the blood clot for 48 hours — no rinsing, spitting, straws, smoking or alcohol — then gentle salt-water rinses after meals; soft food; painkillers taken ahead of the anaesthetic wearing off. Lower wisdom sockets are the most dry-socket-prone in the mouth, so pain that worsens after day two instead of easing is your cue to call us rather than push through.
Living with wisdom teeth you keep
Retained wisdom teeth need maintenance: deliberate brushing at the very back (a single-tufted brush reaches where a full head cannot), and inclusion in your routine check-ups so decay and gum problems around them are caught early. Partly erupted teeth that misbehave occasionally but not often can be managed this way for years — with the understanding that the removal conversation reopens if episodes become frequent or the neighbouring tooth starts paying the price.
