The Indications for Third-Molar Extractions

Third molars, commonly known as wisdom teeth, are the last set of molars that typically emerge in young adulthood, usually between the ages of 17 and 25. While some people have enough space in their mouths to accommodate these teeth without any issues, many individuals experience problems that necessitate their removal.  

In this blog we will explore the reasons why wisdom teeth may need to be extracted, the potential complications, and more.

Common Age for Extraction

Most individuals will start to see their wisdom teeth emerge in their late teens or early twenties. Even though the exact timing can vary. Some people may find that their wisdom teeth come in without any issues.  

On the other hand, others may experience complications that prompt a dentist to recommend extraction. Regular dental check-ups are essential during this time to monitor the development of these teeth.

Indications for Third-Molar Extraction

Several factors can indicate that a person should have their wisdom teeth extracted. Here are some of the most common reasons:

Impaction

One of the most common reasons for wisdom tooth removal is impaction. This occurs when there is not enough space in the mouth. This will be causing the tooth to become trapped beneath the gum line. Impacted wisdom teeth can lead to pain, swelling, and infection.

Crowding

Even if wisdom teeth come in normally, they can sometimes push against neighboring teeth. It will be causing crowding and misalignment. This can be particularly concerning for individuals who have had braces or orthodontic work.  

Crowded teeth can complicate oral hygiene which makes it harder to clean effectively. This misalignment can lead to uneven wear on teeth, increased risk of cavities, and gum disease.

Cavities and Gum Disease

Wisdom teeth are located at the back of your mouth. This makes it hard to clean properly. Due to this, they are more likely to get cavities and gum disease.  

If a wisdom tooth gets a cavity that can’t be fixed, it may need to be removed. Gum disease around these teeth can also cause more problems if not treated. This is because the bacteria can spread to other parts of the mouth, worsening any existing dental issues.

Pain and Discomfort

If wisdom teeth begin to grow in and cause pain, discomfort, or swelling. It may be an indication that they need to be removed. Some individuals experience jaw pain or headaches related to their wisdom teeth.

Infection

When wisdom teeth are only partially out, they can create pockets in the gums where bacteria can grow, leading to infections. Symptoms of an infection may include pain, swelling, bad breath, and even fever.  

In these cases, removing the tooth can help solve the problem.  

The infection can also cause a condition called pericoronitis. This is inflammation of the gum tissue around the partially erupted tooth. This can be very uncomfortable and make it hard to keep your mouth clean.

Cysts and Tumor

In rare cases, wisdom teeth can lead to cysts or tumors in the jaw. These growths can harm nearby teeth and bone, making it necessary to remove the affected tooth.  

Cysts can create larger spaces in the jawbone and may require further surgery. If not treated, these cysts can result in serious problems, including bone loss.

Preventive Measures

Some dentists suggest removing wisdom teeth before they cause problems, especially if X-rays show that the teeth are impacted or likely to cause issues later. Taking out wisdom teeth early can help patients avoid more complicated procedures and discomfort in the future.  

This is particularly common for younger patients. This is because their tooth roots are not fully developed. This makes removal easier and recovery faster.

What to Expect During the Extraction

If your dentist determines that your wisdom teeth need to be removed, here is what you can expect during the procedure:

Consultation

Before the extraction, you will have a consultation with your dentist or oral surgeon. They will discuss your medical history, take X-rays, and explain the procedure in detail.

Anesthesia

Depending on the complexity of the extraction and your comfort level, the dentist will administer local anesthesia, sedation, or general anesthesia. This helps ensure that you remain pain-free during the procedure.  

Procedure

The dentist will remove the wisdom teeth through a surgical procedure. It may involve cutting through the gum tissue and possibly removing some bone. If the teeth are impacted, they may be broken into smaller pieces for easier removal.

Duration  

The extraction usually takes around 30 minutes to an hour. The exact time will depend on the number of teeth being removed and their condition.

When to Call Your Dentist?

While recovery is typically straightforward, there are some signs that you should contact your dentist:

Excessive Bleeding

If bleeding does not subside after a few hours or becomes severe, reach out to your dentist. Minor bleeding is normal, but significant bleeding requires attention.  

Severe Pain

Some discomfort is normal. However, if you experience severe pain that worsens over time, it may indicate an issue that requires attention. Dry sockets or infection can cause increased pain. If you suspect you have dry socket, then your dentist can provide treatment to alleviate the discomfort.
