Wisdom Tooth Extraction: Why It's Necessary and What to Expect

Wisdom teeth are the last teeth to erupt in your tooth row. They usually appear between the ages of 17 and 25, but some individuals may not experience them at all. They are located at the back of the mouth, and in most cases, they are the last to erupt. Although it is a natural process, the presence of wisdom teeth can often cause problems for some people.

For most individuals, wisdom teeth erupt without any issues. However, for others, they can cause pain, inflammation, and other problems such as teeth growing crooked or stuck under the gum. This condition can lead to various complications, sometimes requiring measures such as wisdom tooth extraction. This article will discuss more about wisdom teeth, signs of problems associated with them, and when you should consider seeking treatment or extraction.

Signs of wisdom tooth problems

Wisdom teeth usually come in without any problems, but sometimes they can cause difficulties. Watch for the following signs:

  • Persistent or severe pain: Pain that doesn’t go away or gets worse in the back of the mouth.
  • Swelling of the gums or cheeks: Red, sensitive gums, or swollen cheeks may indicate an infection.
  • Difficulty opening the mouth: Pressure on the jaw joint makes it difficult to open the mouth fully.
  • Bad breath: Bad breath that doesn’t go away can indicate a buildup of bacteria due to wisdom teeth not growing in properly.

When to see a dentist immediately

If you experience any of the following: unbearable pain, fever, swelling that gets worse, or signs of infection such as pus or a foul odor.

When should wisdom teeth be removed?

Not all wisdom teeth need to be removed. However, dentists will usually recommend surgery if the wisdom teeth are causing oral health problems. These include teeth that are stuck under the gums or growing in at an angle that is pressing on other teeth, causing recurring pain or gum infections, or leading to the formation of cavities (cavities) and gum disease because the area is difficult to clean.

In addition, wisdom teeth can also cause crowding of teeth or damage the structure of adjacent teeth. If this problem is left untreated, it can lead to more serious complications. Therefore, regular check-ups with your dentist are very important to determine whether your wisdom teeth need to be extracted or can be left untreated.

Wisdom tooth extraction process

1. Anesthesia and preparation

Before the procedure begins, the dentist will administer a local anesthetic to numb the area around the wisdom tooth and make it pain-free. In more complicated cases, general anesthesia may be used to keep you asleep throughout the procedure.

2. Withdrawal process

Once the area is numb, the dentist will begin the extraction. If the wisdom tooth is hidden in the gum, the dentist may need to make a small incision in the gum or split the tooth into several pieces to make the process easier. Special instruments are used to stabilize the tooth before it is carefully removed.

3. Wound closure

After the tooth is removed, the gum may be stitched to close the wound and speed healing. In the case of small wounds, stitches are not always necessary.

What to expect

  • Procedure Duration: Wisdom tooth extraction usually takes 30 minutes to 1 hour, depending on the condition of the tooth and the level of difficulty. Teeth that are crooked or impacted may require more time.
  • Discomfort Level: During the procedure, you will not feel any pain because the anesthesia is fully effective. After the procedure, when the anesthesia wears off, you may experience some discomfort or mild pain. The dentist will usually provide painkillers to help. This pain usually subsides within a few days.

Preparation before the draw

1. Initial examination & X-ray

Before wisdom tooth extraction is performed, the dentist will conduct an initial examination to assess the condition of your teeth and mouth. This examination will help the dentist understand the position of the wisdom tooth and whether it is trapped in the gums or growing crookedly.

In addition to a physical examination, the dentist may take an X-ray to better understand the position of your wisdom tooth before the procedure begins, the root of the tooth, and the surrounding tissues. This allows the dentist to plan the extraction procedure more accurately and reduce the risk of complications.

2. Things to do before the day of the procedure

  • Eat Enough (for Local Anesthesia): If your wisdom tooth extraction involves local anesthesia, you are allowed to eat normally before the procedure. However, if you are scheduled for general anesthesia, your dentist may advise you to fast for at least 6 to 8 hours before the procedure. This is important to ensure an empty stomach and avoid the risk of vomiting during the anesthesia process.
  • Sufficient Rest: Before the day of the procedure, make sure you get enough rest. A good night’s sleep will help your body prepare for the procedure and the recovery afterward. Feeling anxious or stressed can add to the tension, so try to feel calm before the day of the tooth extraction.
  • Medications to Take: If you are taking certain medications, be sure to tell your dentist. This includes blood thinners or other medications that may affect the procedure or recovery. Your dentist may advise you to stop taking some medications before the procedure or to substitute them with more appropriate ones. If you need to take antibiotics before the procedure (especially if you have a history of infections or certain medical conditions), be sure to follow your dentist’s instructions.

3. Mental and emotional preparation:

Don’t hesitate to talk to your dentist about any concerns or anxieties you may have about the procedure. A clear explanation and better understanding of the procedure can help reduce any fear or anxiety.

Care after wisdom tooth extraction

After wisdom tooth extraction, proper care is very important to prevent infection and speed up recovery.

First day

A little bleeding is normal. Bite on gauze for 30–45 minutes to stop the bleeding, and repeat if necessary. Swelling usually goes away in 1–2 days, while pain can be controlled with painkillers recommended by your dentist. On the first day, choose soft foods such as cold soup or yogurt, and avoid straws, hard foods, or hot drinks.

Reduces swelling & pain

Apply an ice pack to your cheek for 15–20 minutes at a time, especially in the first 24 hours. Sleep with your head slightly elevated to reduce swelling. Avoid strenuous activity that may trigger rebleeding.

Warning signs after tooth extraction

Contact your dentist immediately if the bleeding does not stop after a few hours, the pain or swelling gets worse after 2–3 days, you have a fever over 38°C, or the wound starts to ooze and smell.

Follow-up check

Most dentists will schedule a follow-up a few days later to make sure the wound is healing properly. Use this session to ask about your recovery.

Cover

In conclusion, wisdom teeth can be problematic for some individuals, but with early attention and proper treatment, many complications can be avoided. If you experience symptoms such as pain, swelling, or difficulty opening your mouth, it is important to get checked out by a dentist immediately. Early action can help prevent more serious problems such as infection or damage to adjacent teeth.

It is important to have regular check-ups with your dentist, as this can identify wisdom tooth problems early and reduce the risk of future complications.
