3 Reasons You Would Need Wisdom Teeth Extraction
1. No Room
Wisdom teeth are always the last teeth to erupt. An overcrowded mouth can cause wisdom teeth to remain fully or partially stuck in the gums and bone tissue after all other teeth have grown in. People who have small jaws may also not have enough room to allow for the eruption and growth of wisdom teeth.
2. Misaligned Bite
An erupting wisdom tooth may push on the tooth next to it as it tries erupting out of the gums. That tooth may push on the one next to it to create more room for the wisdom tooth. This domino effect can eventually cause a misaligned bite and problems with biting, chewing and talking.
Pericoronitis is the swelling and infection of the gums around wisdom teeth that have partially erupted or not at all. Pericoronitis occurs when a partially erupted wisdom tooth creates a flap of gum tissue that traps food particles and other debris. Symptoms of pericoronitis may include painful, swollen gums near wisdom teeth, discharge of pus, unpleasant smell or taste in the mouth, swollen lymph nodes, jaw spasms, and difficulty breathing and/or swallowing.
Understanding Wisdom Teeth Extraction
Wisdom teeth, also known as third molars, usually start to erupt in young adults between the ages of 17 and 21. Most people do not have enough room in their mouths for these 4 additional teeth and end up having them extracted.
When wisdom teeth are left inside the gums or erupt only part of the way, pockets can develop in the gums around wisdom teeth to collect food debris and bacteria. This increases the risk of plaque buildup, decay, and infection. Having wisdom teeth extracted can reduce these risks and keep the teeth, gums, and mouth healthy.
Risks of Wisdom Teeth Extraction
The risks of wisdom tooth extraction are the same as those for any other tooth extraction. Blood clots inside tooth sockets can fall out following extraction, which can cause dry sockets. Dry sockets can expose bones and nerves to the air to cause pain and delayed healing. Nerves and blood vessels may also be damaged during wisdom tooth extraction to cause bleeding, temporary numbness in the tongue and/or face, and infection.
Other risks involved with wisdom tooth extraction include fractures caused by dental instruments, damage to restorations and other teeth, and reactions to local anesthesia and medicines used during the procedure.
What to Expect with Wisdom Teeth Extraction
Wisdom tooth extraction may be performed by a dentist, oral surgeon, or periodontist at a hospital or dental clinic. Wisdom teeth are usually removed under local anesthesia to prevent you from feeling pain in the gums and mouth, though general anesthesia may be used in more complex cases that involve the extraction of several teeth.
First, the dentist will make an incision in the gum tissue covering the wisdom tooth and detach the connective tissue between the tooth and bone. Then, an instrument called an elevator is used to loosen the tooth in the gum to make for easier extraction. Forceps may be used to pull the tooth up and out of the gum. Wisdom teeth that are difficult to remove using forceps may be cut into several pieces before being extracted.
After the wisdom teeth are removed, your dentist will clean and disinfect the gum sockets before closing them with sutures. Your cheeks and gums may be swollen and painful for the first few days following wisdom teeth extraction. Pain and discomfort are normal and can be relieved using over-the-counter or prescription painkillers, as well as an ice pack.
For the first 24 hours after wisdom tooth extraction, your dentist may instruct you not to brush, floss, spit or rinse your mouth. You may also be instructed to keep gauze in your mouth to stop bleeding and help blood clots form inside the sockets, and be provided with a plastic syringe that can be filled with water or a medicated solution. The syringe can be used to clean the area in your mouth where the wisdom teeth were removed to help reduce the risk for infection.
