Your Complete Guide to Wisdom Teeth Removal

The evaluation starts with a CBCT scan. A flat X-ray shows that a tooth is there; a 3D scan shows exactly where it sits relative to the inferior alveolar nerve in the lower jaw and the maxillary sinus in the upper. That relationship dictates both whether removal is straightforward and which technique is used, so it is measured rather than estimated.

Removal is generally recommended when a tooth is impacted and unlikely to erupt into a usable position, when the tooth is partially erupted — which creates a pocket that cannot be cleaned and repeatedly becomes infected — when there is decay or resorption on the adjacent second molar, when a cyst is forming around the crown, or when crowding and periodontal breakdown are progressing behind the second molar.

The counter-argument matters too. A fully erupted, cleanable, asymptomatic wisdom tooth in good position can reasonably be monitored. What is not reasonable is monitoring a partially erupted tooth indefinitely and hoping the infections stop, because each episode damages the bone around the neighbor.

The single strongest predictor of how easy a third molar extraction will be is age. In the late teens and early twenties, the roots are often incompletely formed and the surrounding bone is less dense and more elastic. Removal is faster, the roots sit further from the nerve, and healing is dramatically quicker.

By the mid-thirties and beyond, roots are fully formed and frequently curved or fused, the bone is harder and less forgiving, and the roots may be sitting directly against the nerve canal. The same tooth that would have taken twelve minutes at nineteen may take forty at thirty-eight, with a longer recovery and a measurably higher risk of temporary nerve irritation.

This is why surgeons raise the subject before anything hurts. Removing a problem tooth prophylactically at twenty is a different operation from removing it urgently at forty because it finally abscessed.

Straightforward, fully erupted extractions are comfortably done with local anesthetic alone. You are awake, the area is completely numb, and you drive yourself home.

Oral sedation — a pill taken before the appointment — adds a layer of calm for anxious patients while keeping you responsive. You will feel drowsy and remember little of the procedure, and you will need someone to drive you.

IV sedation is the usual choice for multiple impacted teeth or for patients with significant dental anxiety. Medication is titrated through a vein, monitored continuously, and adjusted in real time, so depth of sedation is controlled precisely. Most patients have no memory of the surgery at all, and the procedure can be completed in a single visit rather than staged.

There is no correct answer here, only the right fit for the complexity of the case and your own tolerance. The choice is made together at the consultation, after your medical history and airway are reviewed.

Once you are comfortable, the tissue over the tooth is opened if the tooth is covered. If the crown is impacted under bone, a small amount of bone over the crown is removed. Curved or multi-rooted teeth are frequently sectioned — divided into pieces — so each root can be delivered along its own path instead of forcing the whole tooth out through a channel too narrow for it. Sectioning sounds aggressive but is the opposite: it is what allows the surrounding bone to be preserved.

The socket is then cleaned of any follicular tissue or infected granulation, irrigated, and treated. At Diamond Arch this is where PRF is usually placed — a plug of your own concentrated platelets to seal the socket and accelerate healing. Sutures are placed as needed; most are the dissolving kind.

For all four teeth with IV sedation, the surgical time is typically thirty to sixty minutes depending on impaction. You will spend additional time in recovery before being discharged with written instructions and a responsible adult.

Day one is about control: gauze pressure until bleeding stops, ice twenty minutes on and twenty off, anti-inflammatories on schedule rather than waiting for pain, cold soft foods, no straws, no smoking, no rinsing. Do not skip the ice — swelling that is prevented is far easier than swelling that has to be treated.

Days two and three are the peak. Swelling is usually at its maximum around forty-eight hours, and stiffness in the jaw is normal. Gentle warm salt water rinses begin after the first twenty-four hours. Bruising along the jawline is common and harmless.

Days four through seven bring steady improvement. Swelling recedes, diet expands to soft solids, and most patients are back to work or class — many earlier. Pain that increases rather than decreases around day three to five, particularly with a bad taste or an empty-looking socket, is the classic dry socket pattern and warrants a call, not stoicism.

By two weeks the sockets are closed over with tissue; full bone fill takes several months and happens quietly in the background. Smokers, patients on hormonal contraceptives, and patients with poor initial oral hygiene have measurably higher dry socket rates, which is worth knowing in advance rather than after.

The common issues are dry socket, prolonged swelling, and localized infection — all manageable and all reduced by good technique and good aftercare. The complication patients ask about most is nerve injury: temporary numbness of the lip, chin, or tongue occurs in a small percentage of lower third molar cases and almost always resolves. Permanent alteration is rare, and its likelihood is predicted directly from where the CBCT shows the roots relative to the canal.

Upper third molars sit close to the sinus, so a small communication with the sinus is possible and is managed at the time of surgery if it occurs. Again, this is why 3D imaging comes first: the anatomy that determines the risk is measured before a decision about approach is made.
