Wisdom tooth flare-ups are common in your late teens and twenties — and most of them are not the tooth itself but inflammation in the gum around it. Here's how to manage a flare at home, when to escalate, and what an online Australian dentist can read from a photo.

A pericoronitis flare usually settles in a few days. The signs below mean the infection has spread beyond the gum and needs hospital-level care — see also the wider guide to dental emergencies in Australia.
Call 000 or head to a hospital ED if any of these are present.
Most wisdom-tooth flare-ups are pericoronitis — gum inflammation around a partially erupted tooth.
The lower wisdom teeth are usually the troublemakers. As they erupt they often only come part-way through, leaving a flap of gum (the "operculum") covering part of the chewing surface — visually, the same kind of swollen-gum lump that points to pericoronitis. Plaque and food debris collect under the flap; the gum gets red, swollen, and tender. Bite down and you might catch the opposite tooth on the flap itself, which makes it worse — and the muscle spasm around it often reads as jaw pain with limited opening (trismus).
Pericoronitis comes in waves. A first mild flare in your late teens. Maybe nothing for a year. Then another, sometimes worse. The pattern usually keeps going until the tooth is either fully erupted into a cleanable position or removed.
Most pericoronitis flares settle within 3–7 days with these measures. If it's getting worse rather than better, escalate.
Most flares settle in 3–7 days with these measures. None of them fix the underlying problem — a partially erupted lower tooth that traps plaque will keep flaring until the gum closes over fully or the tooth is removed. The line between "flare you wait out" and "flare that's pointing toward extraction" is the part patients most often misread.

That's exactly what askadent is built to answer. Send a photo of the area and a short description; an AHPRA-registered Australian dentist replies within 24 hours with a plain-English read on what you're seeing — and a referral letter for extraction if it's time to plan it.

Removal is usually done by an oral surgeon or a dentist with surgical training, under local or general anaesthetic depending on complexity. Recovery is typically 3–7 days. In rural areas, the wait for a surgical appointment can be long — knowing you'll eventually need it lets you book in early. Our wisdom tooth removal fee benchmark shows what typical Australian quotes look like per tooth, with and without IV sedation or GA in hospital.
If you're in a flare and not sure whether to manage at home, drive in to a dentist, or head straight to an ED, that's the gap askadent is built for.

What it can't do: prescribe antibiotics (legal requirement for in-person care in Australia), do an x-ray, or remove the tooth. For acute spreading infection, a hospital ED is the right call.
