Dental extraction

A dentist can pull a tooth.

This helps if a tooth is hurting. A tooth might hurt from decay. It can also hurt from an injury.

Sometimes, teeth are too crowded. A dentist pulls a tooth to make space. This helps the other teeth stay straight.

First, the dentist makes the area numb. They use a special medicine for this. This helps the person not feel pain.

Next, the dentist uses tools to lift the tooth.

They use tools like forceps to grip it. They may rock the tooth to loosen it.

After the tooth is out, the dentist helps it heal. You might bite on a piece of gauze. This helps stop the bleeding.

A dental extraction is when a dentist removes a tooth.

This is often done if a tooth has bad decay. It might also happen if a tooth is hurt by an injury. Sometimes, wisdom teeth get stuck in the gums. These are called impacted teeth. Dentists may remove them to stop infections. Another reason is to make space for straight teeth. This is part of orthodontic treatment, which uses braces.

First, the dentist makes the area numb. They use a local anaesthetic. This is a medicine that stops you from feeling pain. They might use a gel on the gums first. This makes the needle feel better.

Next, the dentist uses special tools. They use forceps, which look like small pliers.

The dentist grips the tooth and moves it slowly. They may rock the tooth to loosen it from its socket. This socket is the hole in the bone where the tooth sits. For hard teeth, they may use a surgical way. This might involve a small cut or splitting the tooth. Afterward, you bite on gauze to stop bleeding. You must avoid using straws for one day. This helps a blood clot form in the socket.

A dental extraction is the process of removing a tooth from its socket. This socket is a space in the jaw bone called the dental alveolus.

Dentists perform extractions for many different reasons. The most common reason is tooth decay, which can account for up to two-thirds of extractions. Other reasons include gum disease or a tooth being hurt by an injury. Sometimes, wisdom teeth become impacted, meaning they are stuck and cannot grow normally.

These teeth can cause infections in the gums. Dentists might also remove healthy teeth to create space for braces. This is a part of orthodontic treatment to help straighten crowded teeth.

Before the work begins, the dentist must make sure the area is numb. They do this by using a local anaesthetic. They might first apply a numbing gel like benzocaine to the gums. Then, they use an injection to deliver the medicine. One way is called infiltration, where the medicine goes near the root tip. Another way is a nerve block, which numbs a larger area like all the lower teeth. Common medicines used in the UK include lidocaine and articaine.

There are two main ways a dentist can remove a tooth. A simple extraction is for teeth that are easy to see in the mouth.

The dentist uses tools to lift and grasp the visible part of the tooth. A surgical extraction is used for teeth that are harder to reach. This might happen if a tooth is broken under the gum or if a wisdom tooth has not fully come in. In these cases, the dentist may need to make a small cut in the gum. They might even use a drill to remove a little bit of the bone. Sometimes, the tooth is split into pieces to make it easier to take out.

Special tools help the dentist work carefully. Forceps are very common and look like small pliers.

The dentist uses them to grip the tooth root and apply steady pressure. They might rock the tooth back and forth to loosen it. Other tools include elevators, which help expand the socket.

There are also luxators, which are sharp tools used to cut the ligament holding the tooth. A dentist might even use a "figure of eight" movement for lower molars. The dentist chooses different shapes of forceps depending on if the tooth is an upper or lower tooth.

After the tooth is out, the patient must help the area heal. Biting on a piece of sterile gauze helps stop bleeding through firm pressure. This helps a blood clot form at the base of the socket.

It is important not to eat or drink hot food for the first 24 hours. Patients should also avoid using straws. The suction from a straw can pull the new blood clot out of the socket. If the clot is lost, it can lead to a painful condition called a dry socket. Most people will see some swelling or bruising as they recover.

Over time, the body heals the space where the tooth used to be.

A dental extraction, also known as exodontia, is the clinical removal of a tooth from its socket. This socket is a space within the alveolar bone called the dental alveolus.

Dentists perform these procedures for many different medical reasons. The most common cause is severe tooth decay, which accounts for up to two-thirds of all extractions. Other causes include periodontal disease, which is severe gum disease that affects supporting bone. Dentists may also remove teeth due to dental trauma or if a tooth cannot be fixed through endodontic treatment.

There are two primary categories of extraction: simple and surgical. A simple extraction is performed on teeth that are clearly visible in the mouth. During this process, the dentist uses instruments to elevate and grasp the visible part of the tooth. They apply slow, steady pressure to expand the socket. Once the periodontal ligament—the tissue connecting the tooth to the bone—is broken, the tooth is removed.

In contrast, a surgical extraction is required when a tooth is difficult to access. This often happens if a tooth is impacted, meaning it is stuck under the gum. In these cases, the dentist may make an incision in the mucosa and periosteum. They might also use a drill or an osteotome to remove surrounding bone to reach the tooth.

Before the procedure begins, the dentist must ensure the patient feels no pain. They use local anesthetics to numb the tooth and surrounding tissues. One method is infiltration, where the anesthetic is injected near the root tip. This allows the medicine to penetrate the bone and reach the nerve bundle. Another method is a nerve block, such as an inferior alveolar nerve block. This technique numbs a larger area, such as all the lower teeth. Common anesthetics used in the UK include lidocaine and articaine.

Specialized instruments are essential for a successful extraction. Forceps are the most common tool and function similarly to pliers. Different shapes of forceps exist for upper and lower teeth, or for specific teeth like molars. The dentist uses the beaks of the forceps to grip the root securely. They then apply pressure along the long axis of the tooth. To loosen the tooth, the dentist may move it toward the cheek side, known as the buccal side, and then toward the tongue, called the lingual or palatal side.

For lower molars, a "figure of eight" movement may be used.

Other tools help manage the socket and the ligament. Elevators, such as the Coupland or the Warrick James, are used to expand the socket and lift the tooth. Luxators are even sharper instruments. They are used to carefully cut the periodontal ligament between the tooth and the bony socket.

If a tooth is very complex, such as a molar with curved roots, it may even be split into multiple pieces. This technique helps facilitate removal while minimizing trauma to the tissues.

After the tooth is removed, achieving haemostasis—the stopping of blood flow—is the next priority. Patients typically bite on sterile gauze to apply firm pressure to the wound. This pressure promotes the formation of a blood clot at the base of the socket. It is vital that patients avoid hot food and drinking through straws for 24 hours. The negative pressure from a straw can dislodge the new clot. If the clot is lost, it can result in a painful condition called a dry socket.

Bleeding from soft tissues can be managed with sutures or chemical agents like silver nitrate. Bony bleeding may require bone wax or electrocautery.

Recovery involves managing common side effects like swelling, bruising, and pain. Some patients may experience trismus, which is the inability to open the mouth as wide as usual. Surgical extractions of wisdom teeth carry specific risks, such as temporary or permanent numbness in the lip, chin, or tongue. This happens if the inferior alveolar nerve or lingual nerve is affected.

Despite these risks, extractions remain a necessary part of dental care, including orthodontic preparations to create space for crowded teeth.
