Wisdom Teeth: To Remove or Not?

The removal question

Unlike the old default "remove all wisdom teeth at 18," modern evidence supports case-by-case decisions. Some wisdom teeth come in perfectly and function for a lifetime; others cause problems and should be removed. The NHS, for example, advises that an impacted wisdom tooth that isn't causing problems is usually left in place and monitored at routine check-ups.

Remove when

• Partially erupted with recurrent gum infection (pericoronitis)
• Decay in the wisdom tooth or adjacent second molar
• Cysts or tumours around the impacted tooth (rare but serious)
• Ongoing pain or pressure symptoms
• Orthodontic treatment requiring space
• Damage to adjacent second molar (root resorption)
• Active gum disease around the tooth

Monitor (don't remove) when

• Fully erupted, functional, cleanable
• Deep bony impaction with no current or likely symptoms
• Patient is elderly and surgery risk outweighs benefit
• Single isolated symptom that resolves with conservative care

The position of the tooth is judged from an x-ray (see dental x-rays explained).

The age factor

• 17–25: easier healing, roots not yet fully formed, the most straightforward surgical window
• 26–40: still straightforward
• 40+: roots more formed, bone denser, slightly more complex recovery
• 60+: significantly higher surgical risk; usually only removed if causing real problems

Types of extraction

Fully erupted, routine

Same as any other extraction. 15–30 min, local anaesthetic, minimal recovery.

Soft-tissue impacted

Tooth through bone but gum partially covers it. Small gum incision, then extraction.

Partial bony impaction

Partly in bone. Gum flap, minor bone removal, extraction.

Complete bony impaction / horizontal

Fully in bone, often on its side. Significant surgical procedure.

Typical cost

At Paradise Dental Clinic (see pricing):

• Simple extraction (a fully erupted wisdom tooth): AED 400–900
• Wisdom tooth (impacted): AED 1,500–4,500 — soft-tissue impactions sit toward the lower end of the range, deep bony and horizontal impactions toward the upper end

Sedation, where it is used, adds to the cost. A fuller breakdown is in wisdom tooth removal cost in Dubai, and the treatment itself is described on the wisdom teeth removal page.

Recovery by extraction type

• Fully erupted: 2–3 days
• Soft-tissue impacted: 3–5 days
• Partial bony: 5–7 days
• Complete bony / horizontal: 7–14 days

Sedation options

For deeper impactions or anxious patients, sedation may be offered, ranging from nitrous oxide to IV sedation. With IV sedation you're drowsy and relaxed but responsive; recovery takes a few hours and you need someone to take you home. Sedation adds to the cost (see sedation dentistry for anxious patients). Complex impactions, such as a tooth lying very close to the nerve, may be referred to an oral surgeon.

Common complications

• Dry socket: more common after lower wisdom teeth, and higher in smokers (see dry socket)
• Paraesthesia (numbness of the lip, chin or tongue): uncommon; most cases resolve over weeks to months, though rarely it can be long-lasting. Imaging before surgery helps assess how close the roots sit to the nerve.
• Sinus communication (upper wisdom teeth close to sinus): managed with careful closure
• Swelling and bruising: normal, peaks at 48–72 hours

What to eat

• Days 1–3: soup, yoghurt, smoothies (no straw), mashed avocado, scrambled eggs, well-cooked pasta
• Days 4–7: softer solids on the opposite side
• Week 2+: normal diet on the opposite side; be cautious on the extraction side for another week

Common questions

Can wisdom teeth come in crooked?

Yes, and it's common. When the jaw doesn't have enough space, a wisdom tooth may come in at an angle, often tilted toward the tooth in front, or stay partly or fully trapped under the gum, which is called impaction. An angled wisdom tooth can press against its neighbour and make the area hard to clean. An X-ray is needed to see the tooth's position and decide whether it should be monitored or removed.

How long does impacted wisdom tooth removal take?

It depends on the impaction. A soft-tissue impaction, where gum covers the tooth, often takes around 20 to 30 minutes; bony impactions take longer, and a deep bony or horizontal impaction, the most involved, can take an hour or more. Recovery scales the same way: three to five days for soft-tissue, five to seven for partial bony, and one to two weeks for full bony cases. Anaesthesia ranges from local only to local with nitrous oxide, IV sedation, or general anaesthesia for complex surgical cases.

Is it normal for wisdom teeth to hurt?

Some discomfort is normal while a wisdom tooth erupts, and it should settle within days to a few weeks. Constant pain, swelling, a bad taste or difficulty opening your mouth are not normal. They can signal pericoronitis, an infection of the gum over a partly erupted tooth, and mean the tooth needs evaluating, often with a view to removal. An X-ray shows whether the tooth is impacted or well aligned and whether removal is recommended.

Are molar extractions more likely to have complications?

Somewhat, yes. Molars have larger, more complex roots, so a root can fracture during removal, and swelling is usually heavier than after a front-tooth extraction. Lower molars carry a higher dry socket risk and sit close to the nerve; the roots of upper molars can sit near the sinus and leave a small opening into it. A surgical extraction is needed when the tooth is below the bone, lies horizontally or has complex roots. Recovery is typically 3 to 7 days for a non-surgical extraction and 7 to 14 days for a surgical one.

Do I need my wisdom teeth removed before braces or Invisalign?

Not automatically. Wisdom teeth should be X-rayed before orthodontic treatment so their position is known. If they are impacted and pushing on neighbouring teeth, or would block planned movements, the timing of removal is planned around the orthodontic treatment, and it is not always needed before it starts. If they have space to erupt or are causing no crowding they can often be monitored. Erupting wisdom teeth are not the main cause of front-tooth crowding after braces; lack of retention is. Retainers remain essential whether or not the wisdom teeth are removed (see how long to wear retainers).

Practical decision guide

General dental decisions should preserve healthy tooth structure whenever possible. A good plan moves from diagnosis to the least-invasive durable treatment, then to prevention so the same problem does not repeat.

Check this first

• X-rays, pulp vitality, crack lines, gum pocketing, bite contacts, and how much natural tooth remains.
• Whether the problem is active disease, old restoration failure, trauma, wear, or a cosmetic concern.
• Whether a filling, onlay, crown, root canal, extraction, or monitoring is the right next step.

When to book sooner

• Pain wakes you at night, lingers after hot or cold, hurts on biting, or comes with swelling.
• A crown or filling falls out, a tooth cracks, or a sharp edge is cutting the tongue or cheek.
• You notice pus, fever, spreading swelling, or difficulty opening, swallowing, or breathing.

Questions to ask at the appointment

• What is the diagnosis, and what evidence supports it on the x-ray or clinical exam?
• What is the smallest treatment that solves the problem predictably?
• What failure signs should I watch for after treatment?

Dubai patient note

If insurance is involved, ask whether pre-approval is required, what codes will be submitted, and what alternatives are clinically acceptable if coverage is limited.
