A wisdom tooth that sits straight, has room to clean and causes no symptoms is a healthy tooth, and we leave it alone.
Most people are told their wisdom teeth need to come out long before any wisdom tooth has caused trouble. Sometimes the advice is right. Sometimes it is reflex. The honest answer depends on three things: the angle the tooth is growing at, the space it has in your jaw, and whether it is causing any symptoms.
What "wisdom teeth" actually are
They are your third molars — the four teeth at the very back of your mouth that usually erupt between 17 and 25. Modern jaws are slightly smaller than the jaws of our ancestors, which means many of us no longer have room for them. Some people have all four, some have two, some have none at all, and some have them but never erupt them.
When removal is the right call
A wisdom tooth typically needs to come out when:
- It is impacted at an angle. Teeth that grow sideways into the tooth in front, or angle backward into the jaw, are almost impossible to clean and put pressure on the second molar — eventually damaging it.
- It has only partially erupted. A flap of gum over a half-emerged tooth traps food and bacteria, causing repeat episodes of inflammation called pericoronitis (painful, swollen, often with bad taste).
- Decay has started. A wisdom tooth at the back is hard to reach with a brush. Decay there can quickly spread to the second molar.
- A cyst has formed around the tooth, visible on an x-ray. Cysts are uncommon but can damage bone if left.
- Orthodontic work depends on creating space — sometimes wisdom teeth are removed to support braces or aligners.
When you can leave them alone
A wisdom tooth that:
- has erupted fully and straight,
- has enough space to clean with a brush and floss,
- causes no pain or swelling,
- shows no decay on examination or x-ray,
is a healthy tooth. We leave it alone, monitor it at routine visits, and treat it like any other molar.
What recovery actually feels like
If removal is the right move, here is the honest picture:
- The procedure itself is short — usually 20 to 40 minutes per tooth for simple cases, longer for fully impacted teeth that require a small bone removal. Most are done under local anaesthetic with optional sedation.
- The first 48 hours are the worst. Expect swelling that peaks on day two, a soft diet, and prescription pain relief for the first day or two.
- By day five most patients are eating normally, off pain medication, and back to work or school.
- Full healing of the soft tissue takes about two weeks; the bone takes three to six months to fill in completely.
After-care that actually helps
- Bite firmly on gauze for the first hour. Replace it once if needed, then stop — over-replacing disturbs the clot.
- No straws, no rinsing, no smoking for 48 hours. All three create suction that can dislodge the clot and cause dry socket — the most common (and avoidable) complication.
- Use a cold pack on the cheek in 20-minute intervals for the first day, then a warm compress from day two onwards.
- Soft foods only for the first three days. Yogurt, eggs, mashed potato, soup. Avoid anything crunchy, spicy or very hot.
- Salt-water rinses start on day two — a teaspoon of salt in warm water, three times a day, gently.
How we decide
A wisdom-tooth assessment in our clinic takes about 40 minutes. We do a thorough exam, take a panoramic x-ray to see the position of all four teeth and their relationship to the inferior alveolar nerve, and discuss the findings with you in plain language. If removal is the right move, we plan it together. If watchful waiting is the right move, we plan that too — usually a check every six months at your routine visit.
We do not believe in removing healthy teeth as a precaution. We do believe in removing problem teeth early, before they cause damage that is harder to undo.
If you have been told you need your wisdom teeth out but no one explained why, that is a good reason to come in for a second opinion. We will show you the x-ray and walk you through what we see.
