Wisdom Tooth Extraction

Wisdom teeth are removed when they are impacted, infected, decayed, or threatening the tooth in front — usually as a planned procedure rather than an emergency.

Watch the short explainer, then read on for what the procedure involves.

Wisdom teeth are the third molars, and they typically try to erupt between the ages of seventeen and twenty-five. Many people simply do not have room for them. When a wisdom tooth cannot emerge into a functional position it is described as impacted, and it may stay buried, erupt partially, or press against the second molar in front of it.

When removal is recommended

Not every wisdom tooth needs to come out. A tooth that is fully erupted, cleanable and in a stable bite can often be left alone and monitored. Removal is advised when there is recurrent pericoronitis — infection of the gum flap over a partially erupted tooth — when decay has developed in the wisdom tooth or the molar next to it, when a cyst forms around the crown, or when the angle of the tooth is damaging the root of its neighbour.

Your dentist at Parkway Dental will use radiographs, and sometimes a 3D scan, to assess the position and the relationship of the roots to the nerve in the lower jaw.

What to expect

Most extractions are done under local anaesthetic, with sedation available. A straightforward erupted tooth may lift out easily. An impacted tooth usually requires a small incision in the gum, sometimes removal of a little overlying bone, and the tooth may be sectioned into pieces so it can be removed through a smaller opening — sectioning is gentler on the surrounding bone, not a sign of difficulty. Sutures may be placed.

Recovery

Swelling typically peaks around day two or three and then improves. Use cold compresses for the first day, take pain relief as advised, and rest.

The key instructions all protect the blood clot in the socket. For the first 24 hours do not rinse vigorously, do not spit forcefully, do not use a straw and do not smoke. Losing that clot causes dry socket — a severe ache starting three to five days later that needs a dressing placed. From day two, gentle warm salt-water rinses help.

Contact us if you have heavy bleeding that does not settle with pressure, worsening pain after day three, fever, or difficulty swallowing or opening your mouth.

Common questions

Do wisdom teeth always need removing?

No. A wisdom tooth that is fully erupted, cleanable and not causing problems can be monitored. Removal is recommended when there is infection, decay, cyst formation or damage to the neighbouring tooth.

What is dry socket and how do I avoid it?

Dry socket occurs when the blood clot is lost from the socket, exposing bone, and causes a marked ache around day three to five. Avoid rinsing vigorously, spitting, straws and smoking for the first 24 hours.

How long is recovery?

Most people return to normal activity within two to three days, with swelling peaking around day two or three. Full healing of the socket takes a few weeks.

Will I be awake?

Most extractions are done under local anaesthetic with you awake and comfortable. Sedation options are available if you are anxious or the case is complex.
