The assumption that wisdom teeth automatically come out is worth examining. Some genuinely should be removed, many are reasonably left alone for years, and the difference is established by an examination rather than by a birthday. Third molars often have too little room to come in properly and can be impacted, decay or cause gum infections in the tissue that covers them, so the dentist tracks them with x-rays and recommends removal when there is a clear problem or a likely one, not automatically at a certain age.
Symptoms that bring people in urgently: wisdom teeth
- Repeated infection or swelling around a back tooth
- Pain behind the last molar
- Food trapping behind a partly erupted tooth
- Decay in a wisdom tooth or the tooth in front of it
- A cyst or change seen on an X-ray
What the dentist may need to do
- Monitoring with periodic X-rays where the tooth is stable
- Cleaning and managing an inflamed gum flap
- Simple removal of an erupted tooth
- Surgical removal of an impacted tooth
- Sedation options for surgical cases
- Referral to an oral surgeon where appropriate
What removal involves
This ranges from a routine extraction to a surgical procedure, and which one you need comes from the X-ray.
- Examination and X-ray, sometimes a 3D scan for lower teeth
- Discussion of the specific risks for your case
- Local anesthetic, with sedation available
- Simple removal, or lifting the gum and sectioning the tooth
- Aftercare instructions and a review if required
Recovery
Surgical removal takes longer to settle than a simple extraction, and planning for that helps.
- Swelling typically peaks around day two to three
- Follow the practice's specific instructions on rinsing and eating
- Do not smoke: it markedly raises the risk of a dry socket
- Arrange a driver if you had sedation
- Contact the practice if pain worsens after day three
Common questions
Wisdom Teeth: questions people ask
Do all wisdom teeth need removing?
No. Many are monitored for years without problems. Removal is advised when a tooth is causing problems or is clearly likely to: see when removal is advised.
What is the nerve risk on lower wisdom teeth?
A nerve runs close to the roots of lower wisdom teeth, and altered sensation is a recognized risk that the surgeon should discuss with you specifically before you consent. Imaging helps assess proximity.
Should all four come out at once?
It is common when all four warrant removal, since it means one recovery. It is not automatic, and you can ask why all four are recommended.
How much time off should I plan?
Ask before booking: it varies between a straightforward extraction and a surgical one. Avoid scheduling anything demanding immediately afterward.
How do I prepare for wisdom tooth removal?
Arrange a driver if sedation is planned, follow any fasting instructions exactly, clear the following day, and stock up on soft food beforehand.
Can I eat before the appointment?
For local anesthetic alone, yes, and it is sensible. For sedation or general anesthesia there are fasting instructions that must be followed exactly.
Is there an age when it is too late?
No, though younger patients often heal more predictably. Age alone is not a reason for or against surgery: the examination and X-rays decide.
