Do You Know the Truth About Wisdom Teeth?
Posted on 6/1/2026 by Keizer Family Dental |
 Let's talk about those mysterious teeth way in the back of your mouth: wisdom teeth! Many people have questions about them, like "Why do we even have them?" and "Do they always need to be removed?". It's important to understand these teeth and how they can affect your overall oral care.
What Are Wisdom Teeth?
Wisdom teeth, also known as third molars, are the last teeth to erupt, usually appearing between the ages of 17 and 25. They are located at the very back of your mouth, behind your second molars. Historically, it's thought that our ancestors needed these extra molars to grind down tougher foods. However, with changes in diet and jaw size over time, many people simply don't have enough room for these teeth to come in properly.
Why Do They Cause Problems?
The biggest problem with wisdom teeth is often a lack of space. When the jaw isn't large enough to accommodate them, they can become impacted. This means they get stuck under the gums or only partially erupt. Impacted wisdom teeth can cause a variety of issues:
| • |
Pain and Discomfort: As the tooth tries to erupt, it can put pressure on surrounding teeth and nerves, leading to pain, swelling, and tenderness in the gums. |
| • |
Infection: Partially erupted wisdom teeth create a pocket where bacteria and food particles can become trapped, leading to infection (pericoronitis). |
| • |
Damage to Adjacent Teeth: Impacted wisdom teeth can push against the second molars, causing damage, decay, or even bone loss. |
| • |
Cysts and Tumors: In rare cases, a cyst or tumor can form around an impacted wisdom tooth, which can damage the jawbone and surrounding tissues. |
| • |
Crowding: While controversial, some believe that erupting wisdom teeth can contribute to crowding of the front teeth, especially if you've had orthodontic treatment. |
What Happens if They Don't Cause Problems?
Sometimes, wisdom teeth erupt fully and are properly aligned. In these cases, and if you can properly clean them, they may not need to be removed. Your dentist will monitor them during your regular check-ups to ensure they aren't causing any issues. Good oral care is especially important if you retain your wisdom teeth. This includes brushing twice a day, flossing daily, and regular dental visits.
How Do I Know If I Need Them Removed?
The only way to know for sure if you need your wisdom teeth removed is to see your dentist for an examination. This will typically involve a clinical exam and X-rays to assess the position of your wisdom teeth and their potential impact on your other teeth and jawbone.
The Removal Process
If your dentist recommends removal, they will discuss the procedure with you in detail. The complexity of the removal depends on factors like the position of the teeth, the number of roots, and their proximity to nerves.
What About After Removal?
Following the removal of your wisdom teeth, it's important to follow your dentist's instructions carefully. This may include taking pain medication, using a cold compress, and eating soft foods for a few days. With proper care, most people recover quickly and without complications. If you have missing teeth elsewhere in the mouth, your dentist can review options for restoration dentistry. |
