Wisdom teeth removal is the extraction of your third molars — the four permanent adult teeth located in the very back of your mouth, in the upper and lower jaws. Wisdom teeth usually erupt between the ages of 17 and 21. Most people have all four of their wisdom teeth. It’s estimated that 5% to 37% of people only have some of their wisdom teeth — or in some cases, none at all.
Why do we have wisdom teeth?
Wisdom teeth were necessary for our ancestors, as their diet mostly consisted of hard nuts, crunchy leaves and uncooked meat. Today, however, we eat more cooked food and use forks and knives to cut our food up into smaller pieces. As a result, wisdom teeth are widely regarded as vestigial structures (parts of the human body that have become unnecessary).
How do I know if I need to get my wisdom teeth removed?
Sometimes all four wisdom teeth erupt normally and don’t cause any problems at all. But oftentimes wisdom teeth grow in at an angle or stay fully or partially trapped (impacted) in the jawbone or under the gum tissue. This can cause a range of problems. We recommend wisdom teeth extraction if you:
- Have dental pain near the back of your mouth.
- Trap food and debris around your wisdom teeth.
- Develop gum disease, particularly around your molars.
- Have tooth decay (cavities) in a partially erupted wisdom tooth.
- Develop a cyst (fluid-filled sac) around one or more wisdom teeth.
- Have sustained damage to nearby teeth or surrounding bone.
In many cases, we recommend wisdom teeth extraction as a preventative measure. As a result, we may suggest removing your wisdom teeth even if you don’t have any symptoms. This can help reduce your risk for future problems, including infection and tooth decay.
At what age should I have my wisdom teeth extracted?
People of all ages can have their wisdom teeth removed. However, we recommend having them extracted in your late teens or early 20s. During this stage of development, your wisdom teeth are still forming. For this reason, they may be easier to remove with less risk of complications.
What happens during wisdom teeth removal?
Once sedation medications have been given, we will administer local anesthesia to numb the teeth and gums. Impacted wisdom teeth (wisdom teeth trapped in the gums or bone) are exposed with incisions, giving us adequate access. Once the wisdom teeth are visible, we carefully loosens and lifts them from their sockets, cleans the areas and places stitches. In most cases, the stitches will fall out on their own in a few days.
How long does wisdom teeth removal take?
Typically, wisdom teeth extraction takes about one hour or less. More complex cases may take longer.
What happens after wisdom teeth removal?
After wisdom teeth removal, you can expect mild discomfort accompanied by slight bleeding and swelling. We will give you instructions for wisdom teeth management to ease these side effects. Once your sedation wears off enough, a friend or family member will drive you home.
What are the advantages of wisdom teeth removal?
The most significant benefit of wisdom teeth extraction is that it reduces the risk for future oral health problems such as gum disease, tooth decay, damage to adjacent teeth, bone loss and jaw damage. If you’ve already developed pain because of your wisdom teeth, then extraction can alleviate discomfort almost immediately and get you back on track to optimal oral health.
How long does it take to recover from wisdom tooth removal?
Most people are comfortable in three to four days, but it can take a couple of weeks for your gums to completely heal. We will provide you with detailed post-surgical instructions to keep you comfortable.
Wisdom teeth removal aftercare
Here are some general guidelines to help foster a comfortable recovery after wisdom teeth removal:
- Rest as much as you can for the first few days.
- Avoid strenuous activity for 48 to 72 hours.
- Place a cold compress or ice pack on your face to help reduce swelling.
- Keep the surgical sites clean by gently soaking them with an antimicrobial mouthwash.
- Don’t swish vigorously, as this can dislodge blood clots and cause dry sockets.
- Brush the rest of your teeth normally.
- Take all medications, including antibiotics and pain relievers, as prescribed.
What to eat after wisdom teeth removal
Stock your kitchen with soft foods like pasta, rice, eggs, pudding and yogurt. Additionally, cool foods like ice cream can help soothe the surgical areas. Steer clear of hard, crunchy and spicy foods, as these things can irritate your tissues. Finally, avoid drinking through straws. The suction can dislodge blood clots, which are essential for healing.
When can I go back to work or school?
Most people can go back to work or school in two to three days after wisdom teeth extraction. However, if your job requires physical labor or heavy lifting, you may need to take a few extra days off of work.
