Wisdom teeth are the third set of molars located at the back of the mouth. They usually emerge between the ages of 17 and 25. For many people, these teeth can cause problems, and they may need to be removed. In this article, we will explore when wisdom teeth are removed, why they are removed, and the process involved. You’ll gain a clearer understanding of this common dental procedure.
What are Wisdom Teeth?
Wisdom teeth are the last teeth on both sides of the upper and lower jaws. They are part of the human dentition that was originally used for grinding and crushing plant-based food. However, with changes in diet over thousands of years, wisdom teeth have become less necessary.
These teeth are typically the last to develop and can emerge later than the other teeth in your mouth. For some, wisdom teeth grow without causing any problems. For others, they can cause pain, infection, or other dental issues.
Why Do Wisdom Teeth Need to Be Removed?
There are several reasons why wisdom teeth are often removed. Let’s go over the most common ones:
1. Impacted Wisdom Teeth
An impacted wisdom tooth is one that does not have enough room to come in or develop properly. This can happen if the jaw is too small, or the teeth are misaligned. When this happens, the wisdom tooth may remain stuck beneath the gum line or come in at an angle.
Impacted wisdom teeth can cause pain, swelling, and even infection if they are not treated. If left untreated, they may affect other teeth and lead to more serious dental problems.
2. Infection and Cavities
When wisdom teeth only partially emerge, they create a flap of gum tissue that can trap food and bacteria. This can lead to infections, gum disease, and cavities. The infection can spread to surrounding teeth and lead to serious oral health issues.
3. Crowding of Other Teeth
If there is not enough space in the mouth for the wisdom teeth to grow in, they may push against the surrounding teeth. This can cause crowding and misalignment of the teeth. As a result, your bite may be affected, and you may require orthodontic treatment to correct the alignment.
4. Gum Disease
Gum disease is common around the wisdom teeth because they are harder to clean. This can lead to swelling, bleeding gums, and bad breath. If not properly treated, gum disease can progress and affect your overall oral health.
5. Cyst Formation
In some cases, impacted wisdom teeth can lead to the development of cysts. These fluid-filled sacs can damage the surrounding bone and tissue. A cyst may require surgical treatment, including the removal of the wisdom tooth.
When Should Wisdom Teeth Be Removed?
Not everyone needs to have their wisdom teeth removed. Your dentist or oral surgeon will evaluate your situation to determine whether removal is necessary. There are several factors that influence this decision.
1. Age
The ideal time to remove wisdom teeth is typically between the ages of 17 and 25. At this age, the roots of the teeth are not fully developed, and the bone around them is softer. This makes removal easier and less risky. Recovery tends to be faster at a younger age as well.
However, wisdom teeth can be removed at any age, depending on the circumstances. If you wait too long and the teeth are fully developed, the procedure may be more complicated, and the recovery period may be longer.
2. Pain and Discomfort
If you experience consistent pain, discomfort, or swelling around the wisdom teeth, it may be time to consider removal. Pain is often a sign that the teeth are impacted, infected, or causing other issues in the mouth.
3. Infection or Gum Disease
If you have frequent infections or gum disease around the wisdom teeth, it may be necessary to remove them. Left untreated, these problems can affect the rest of your oral health and lead to more serious issues.
4. Difficulty Cleaning
If you find it difficult to clean the wisdom teeth, leading to cavities, infection, or gum disease, removal may be the best option. The location of wisdom teeth makes them hard to reach with a toothbrush or floss, and poor oral hygiene can result in serious health issues.
5. Orthodontic Treatment
If you have braces or other orthodontic work done, your dentist may recommend removing your wisdom teeth to prevent them from affecting the alignment of your other teeth. This is especially true if there is not enough space in your mouth for the wisdom teeth to come in.
How is Wisdom Teeth Removal Performed?
The process of removing wisdom teeth typically involves a few steps. Below is an overview of the procedure.
1. Consultation and X-Rays
Before removing the wisdom teeth, your dentist will examine your mouth and take X-rays. These X-rays help the dentist see the position of the teeth, whether they are impacted, and how deep the roots are. This information is crucial for planning the surgery.
2. Anesthesia
Depending on the complexity of the extraction, your dentist or oral surgeon will use either local anesthesia, sedation, or general anesthesia. Local anesthesia numbs the area around the teeth, while sedation helps you relax. General anesthesia puts you to sleep during the entire procedure.
3. Removal Process
The dentist or surgeon will make an incision in the gum tissue to access the wisdom tooth. If the tooth is impacted, it may be broken into smaller pieces for easier removal. After the tooth is removed, the gum is stitched up.
4. Recovery and Aftercare
After the procedure, you will need some time to recover. Most people experience swelling, bruising, and discomfort for a few days following the removal. Your dentist will provide you with instructions for managing pain, reducing swelling, and caring for your mouth during recovery.
In some cases, antibiotics may be prescribed to prevent infection. It is important to follow your dentist’s instructions carefully to ensure proper healing and avoid complications.
What to Expect After Wisdom Teeth Removal?
The recovery process varies from person to person, but most people experience similar symptoms. Here is what you can expect:
1. Pain and Swelling
Pain and swelling are common after wisdom teeth removal. The pain usually peaks within the first 24 to 48 hours and then begins to subside. Swelling typically reaches its peak within 2 to 3 days and then gradually improves.
2. Bleeding
Some bleeding is normal after the procedure, but it should stop within a few hours. If bleeding persists or is excessive, contact your dentist immediately.
3. Difficulty Opening the Mouth
It is common to have limited mouth opening due to swelling. This should improve over the first few days.
4. Bruising
Some people experience bruising on the cheeks or jaw, which can last for several days.
5. Diet Restrictions
For the first few days after the procedure, you will need to stick to soft foods and avoid hot or spicy foods. It is also important to stay hydrated and follow any other dietary recommendations provided by your dentist.
Complications of Wisdom Teeth Removal
While wisdom teeth removal is generally safe, complications can occur. Some potential complications include:
1. Dry Socket
Dry socket occurs when the blood clot in the socket where the tooth was removed dislodges or dissolves too soon. This can expose the bone and nerves, causing intense pain. To avoid dry socket, follow your dentist’s instructions carefully and avoid sucking on straws or smoking.
2. Infection
Although rare, infection is possible after wisdom teeth removal. Signs of infection include fever, severe pain, and pus drainage. If you experience any of these symptoms, contact your dentist.
3. Nerve Injury
In very rare cases, the nerves near the wisdom teeth can be damaged during removal. This can result in temporary or permanent numbness in the lips, tongue, or chin.
Conclusion
Wisdom teeth are often removed due to issues such as impaction, infection, and misalignment. It is important to consult with your dentist regularly and consider removal if necessary. Early intervention can help prevent complications and promote better oral health in the long run.
Remember, the best time to remove wisdom teeth is typically during the late teen years or early twenties. If you are experiencing discomfort or other issues related to your wisdom teeth, schedule a consultation with your dentist to determine the best course of action.
