Wisdom Tooth Removal

What are wisdom teeth and why do they cause problems?

Wisdom teeth are the third molars, usually erupting between the ages of seventeen and twenty-five. Modern jaws are frequently too short to accommodate them, so they emerge at an angle, only partially, or remain fully buried in the bone. A tooth that cannot erupt into a cleanable position is described as impacted.

Partially erupted wisdom teeth are the most troublesome. The flap of gum over them traps food and bacteria, leading to recurrent infection known as pericoronitis. Angled teeth press on the second molar in front, causing decay or bone loss on a tooth you need to keep. Fully buried teeth can, over years, develop cysts around the crown.

Signs a wisdom tooth needs to come out

Some impacted teeth cause no trouble for decades. The following are the signs that intervention is warranted:

• Pain, swelling or a bad taste at the back of the mouth, often in recurring episodes
• Difficulty opening the mouth fully or pain on swallowing during a flare-up
• Decay in the wisdom tooth or in the back of the second molar it leans against
• Gum disease and bone loss around the second molar
• A cyst or other lesion visible on an X-ray
• A wisdom tooth in the way of orthodontic treatment or a planned prosthesis

When monitoring is the better choice

A fully erupted wisdom tooth that meets its opposite number, can be brushed and has no decay is simply a molar and stays. A deeply buried tooth with no pathology and a close relationship to the nerve may also be left and reviewed. Your dentist confirms after examination and imaging which category your teeth fall into.

Assessment and CBCT planning

A panoramic X-ray shows the position of all four wisdom teeth and their general relationship to the surrounding structures. Where a lower tooth appears close to the inferior alveolar nerve, which supplies sensation to the lip and chin, a CBCT scan provides a three-dimensional view. It shows whether the roots wrap around the nerve canal or merely overlap it in two dimensions, and that distinction changes the surgical approach.

The scan also reveals root shape, bone density and the position of the maxillary sinus above upper wisdom teeth. With this information the surgeon knows before starting how the tooth will be sectioned and where care is needed, which makes the procedure shorter and the recovery easier. For visiting patients, imaging and surgery are usually scheduled within the same visit.

Wisdom tooth extraction step by step

Simple extraction of an erupted tooth takes minutes. Surgical removal of an impacted tooth follows a planned sequence:

• Local anaesthetic, with sedation available for anxious patients or when several teeth are removed at once
• A small incision in the gum and, where needed, removal of a little bone to expose the crown
• The tooth is often divided into sections so each piece can be removed through a smaller opening
• The socket is cleaned and any sharp bone edges are smoothed
• Dissolvable stitches close the gum; no removal appointment is needed
• Written aftercare, medication and a direct contact number are provided before you leave

Simple vs surgical extraction

An erupted tooth with straight roots is loosened and lifted out without an incision. An impacted or curved-rooted tooth requires a surgical approach. The difference affects recovery time and aftercare, and is explained to you beforehand so there are no surprises.

Recovery and aftercare day by day

The first twenty-four hours are about protecting the blood clot in the socket. Bite on the gauze, avoid rinsing, spitting, straws and smoking, and rest with your head slightly raised. Swelling peaks on the second and third day and then subsides; cold compresses in the first day and warmth thereafter help. Bruising on the cheek in the following days is not unusual for lower teeth.

Soft, cool food for the first days, gentle warm salt-water rinses from day two, and the prescribed pain relief taken on schedule rather than when pain becomes severe make the process manageable. Most patients feel largely normal within a week, though the socket takes several weeks to close and months to fill fully with bone. The complete protocol is in the aftercare guide.

Flying home after extraction

A flight can normally be taken from around forty-eight hours after surgery. The clinic plans your stay so that the most tender days pass before departure, and provides a written summary for any dentist you may see at home. See international patient information for how this is coordinated.

What happens if a problematic wisdom tooth is left

Recurrent pericoronitis tends to become more frequent and more severe with each episode. Decay on the back of the second molar is difficult to restore and can result in losing a tooth that would otherwise have lasted a lifetime. Cysts enlarge silently and can weaken the jaw. The surgery itself also becomes harder with age as bone densifies and roots complete their formation, so a tooth that is straightforward to remove in your twenties may be more demanding at fifty.

None of this means every wisdom tooth must go. It means that a tooth already causing problems is unlikely to stop, and earlier removal is generally simpler than later removal.

Risks of wisdom tooth removal

Every surgical extraction carries some risk. Dry socket, where the blood clot is lost and the bone is exposed, causes significant pain from the third day and is treated with a medicated dressing; it is more common in smokers. Infection, prolonged bleeding and limited mouth opening for a few days are other possibilities.

The risk specific to lower wisdom teeth is altered sensation of the lip, chin or tongue from bruising of the nearby nerves. It is usually temporary and is uncommon when the relationship to the nerve has been mapped on CBCT. Where the roots genuinely surround the nerve, a coronectomy, removing the crown and leaving the roots in place, may be offered as a safer alternative. Upper teeth carry a small risk of communication with the sinus. Each of these is discussed with you in the context of your own scan, within the broader general dentistry assessment.
