By understanding the impact of wisdom teeth extraction, you can make well-informed decisions about your dental care and potentially avoid a host of oral health issues down the road.

The Impact of Wisdom Teeth Extraction on Oral Health

Ever asked yourself, “What happens if I don’t get my wisdom teeth removed?”

Wisdom teeth, also known as third molars, often emerge in your late teens or early twenties. While some people never experience issues with their wisdom teeth, others encounter discomfort and complications that necessitate their removal. The decision to extract wisdom teeth should never be taken lightly, as it significantly impacts your oral health. This friendly guide aims to provide you with all the information you need to understand the impact of wisdom teeth extraction on your oral health.

What Are Wisdom Teeth?

Wisdom teeth are the last set of molars to appear in your mouth, typically emerging between the ages of 17 and 25. These teeth were crucial for our ancestors who had larger jaws and needed these extra molars to chew hard roots, nuts, and meats. However, due to changes in diet and jaw sizes over time, wisdom teeth have become less necessary. Consequently, modern humans often face complications when these teeth try to emerge.

Why Do We Develop Wisdom Teeth?

From an evolutionary perspective, wisdom teeth were beneficial for our ancestors who had a coarse diet that caused significant wear and tear on their teeth. Having an extra set of molars helped them grind down tough foods and maintain effective chewing surfaces. Today, our diets are softer, and dental care has improved, making these extra molars more of a nuisance than a necessity.

The Common Problems Associated with Wisdom Teeth

Wisdom teeth can lead to various oral health problems, especially if they don’t emerge properly. Here’s a detailed breakdown of common issues:


One of the most common issues with wisdom teeth is impaction. When a tooth is impacted, it’s unable to fully emerge through the gum line due to lack of space. This can lead to several complications, including pain, swelling, and infections. Impacted wisdom teeth can be divided into four categories:

Type of Impaction Description
Mesial Impaction The tooth is angled forward toward the front of the mouth.
Vertical Impaction The tooth does not fully break through the gum line.
Horizontal Impaction The tooth is lying completely horizontal and growing into the roots of adjacent teeth.
Distal Impaction The tooth is angled towards the back of the mouth.


Another common problem is the misalignment of wisdom teeth. When these teeth grow at an angle, they can push against your other teeth, causing crowding and disrupting the alignment of your smile. Misalignment can also make it difficult to clean your teeth properly, leading to increased risks of cavities and periodontal disease.


Partially erupted wisdom teeth can create a flap of gum tissue that can trap food particles, debris, and bacteria. This creates a breeding ground for infections. Pericoronitis, an infection of the gum tissue surrounding an impacted tooth, is a common issue that can cause pain, swelling, and difficulty in opening your mouth.

Cysts and Tumors

Impacted wisdom teeth can also lead to the development of cysts or even tumors in your jawbone. These fluid-filled sacs can cause significant damage to your jaw, teeth, and nerves if not treated promptly. Although rare, these conditions can have serious repercussions on your oral health.

The Importance of Wisdom Teeth Extraction

Given the myriad of problems that can arise from impacted or misaligned wisdom teeth, extraction often becomes a necessary step to protect your oral health. But what exactly does wisdom teeth extraction entail, and how does it benefit you?

Eases Pain and Discomfort

One of the most immediate benefits of wisdom teeth extraction is the relief from pain and discomfort. Impacted or misaligned wisdom teeth can cause significant pain. Removing these teeth alleviates these issues almost instantly.

Prevents Future Dental Issues

By extracting problematic wisdom teeth, you can prevent more severe dental issues from developing down the line. This includes not only the aforementioned problems like infections and cysts but also more subtle issues like tooth decay in neighboring teeth due to difficulty in cleaning.

Reduces Risk of Oral Diseases

Partially erupted wisdom teeth are prone to collecting bacteria and food particles, which can lead to oral infections and diseases. Extraction minimizes this risk, helping you maintain a healthier mouth.

Improves Oral Hygiene

When wisdom teeth are removed, it becomes easier for you to brush and floss effectively, enhancing your overall oral hygiene. Improved oral hygiene reduces the risk of cavities, gum disease, and other dental problems.

Enhances Alignment

Removing problematic wisdom teeth can prevent the crowding of your other teeth, helping to preserve the alignment of your smile. This is particularly important for individuals who have had orthodontic work in the past.

The Extraction Process: What to Expect

If you’ve decided to or are required to undergo wisdom teeth extraction, it’s natural to wonder what the procedure will be like. Knowing what to expect can help ease your nerves and allow you to prepare more effectively.

Initial Consultation

Before the actual extraction, you’ll undergo a thorough consultation with your dentist or oral surgeon. This will involve X-rays to assess the position of your wisdom teeth and determine the most appropriate course of action. During this consultation, feel free to ask any questions you might have to better understand the procedure.

The Procedure

Wisdom teeth extraction is usually an outpatient procedure, meaning you’ll be able to go home the same day. Here’s what typically happens:

  1. Anesthesia: You’ll be given anesthesia to ensure you feel no pain during the extraction. This could be local anesthesia to numb the area, sedation to relax you, or general anesthesia to make you sleep throughout the procedure.

  2. Tissue Removal: The surgeon will make an incision in your gum tissue to expose the tooth and bone if it hasn’t fully erupted.

  3. Bone Removal: If necessary, a portion of the bone covering the tooth may be removed.

  4. Tooth Extraction: The tooth is then removed. If the tooth is large or impacted, it might need to be removed in smaller pieces.

  5. Stitching: The incision is stitched up to promote healing.

  6. Gauze Placement: Gauze is placed over the extraction site to control bleeding and help form a blood clot.


Recovery from wisdom teeth extraction typically takes about a week. Here’s a brief overview of what to expect:

  • Day 1: Rest and apply ice packs to reduce swelling.
  • Days 2-3: Swelling and discomfort may peak, but can be managed with prescribed painkillers and ice packs.
  • Day 4 onwards: Gradual reduction in swelling and pain. Soft foods and plenty of fluids are recommended.
  • End of Week: Stitches (if non-dissolvable) are usually removed, and you can return to your normal diet and activities.

Throughout the recovery process, it’s crucial to follow your dentist’s post-operative care instructions to prevent complications such as dry socket and infection.

Potential Risks and Complications

As with any surgical procedure, wisdom teeth extraction comes with its own set of risks and potential complications. Being aware of these can help you take appropriate precautions and seek prompt medical attention if necessary.

Common Risks

Some common risks include:

  • Pain and Swelling: Mild to moderate pain and swelling are normal after the procedure. These can usually be managed with medication and ice packs.
  • Bleeding: You may experience some bleeding for the first 24 hours. It’s essential to follow your dentist’s instructions to control it.

Less Common Complications

Although less common, some complications can be more serious:

  • Dry Socket: This occurs when the blood clot that forms in the socket dislodges prematurely, exposing bone and nerves. It can cause severe pain and delay healing.
  • Infection: Signs of infection include persistent swelling, pain, fever, and pus discharge. Immediate medical attention is required to treat infections effectively.
  • Nerve Damage: Rarely, the procedure can damage the trigeminal nerve, causing numbness or tingling in your tongue, lips, or chin, which can be temporary or permanent.

Long-Term Impact on Oral Health

You might wonder how wisdom teeth extraction impacts your oral health in the long run. Here’s a closer look at the long-term benefits and considerations:

Improved Oral Hygiene

As mentioned earlier, removing wisdom teeth makes it easier to maintain good oral hygiene. With fewer hard-to-reach areas in your mouth, brushing and flossing become more effective, reducing the risk of cavities and gum disease.

Reduced Risk of Future Dental Issues

By eliminating problematic wisdom teeth, you reduce the risk of developing severe dental issues later on. This includes impactions, infections, and alignment problems that could otherwise compromise your oral health.

No Negative Impact on Chewing and Biting

Many people worry that removing wisdom teeth will affect their ability to chew and bite properly. The good news is that the remaining teeth can adequately handle the workload, ensuring no negative impact on your chewing and biting functions.

Monitoring Remaining Teeth

It’s important to continue monitoring your remaining teeth, as changes in the bite can occur after extraction. Regular dental check-ups are essential to ensure your oral health remains optimal.

Myths and Facts about Wisdom Teeth Extraction

Preparing for Wisdom Teeth Extraction

Preparing for wisdom teeth extraction can make the experience smoother and less stressful. Here are some steps you can take to get ready for the procedure:

Discuss with Your Dentist

Open communication with your dentist or oral surgeon is crucial. Discuss any concerns or questions you have about the procedure, including what type of anesthesia will be used, the risks involved, and what to expect during recovery.

Plan for Recovery

Arrange for someone to drive you home after the procedure, as anesthesia can impair your ability to drive. Stock up on soft foods and beverages that are easy to consume during your recovery period. Plan to take time off from work or school to rest and heal properly.

Follow Pre-Operative Instructions

Your dentist will provide specific pre-operative instructions, such as fasting before the procedure if general anesthesia is used. It’s essential to follow these instructions carefully to ensure a smooth and successful extraction.

Post-Extraction Care Tips

Proper post-extraction care is vital for promoting healing and preventing complications. Here are some tips to ensure a smooth recovery:

Control Bleeding

After the extraction, you’ll need to control bleeding by biting down gently on a gauze pad placed over the extraction site. Change the gauze as needed and follow your dentist’s instructions on how long to keep it in place.

Manage Pain and Swelling

Use ice packs on your face to reduce swelling and take prescribed pain medication as directed. Over-the-counter pain relievers like ibuprofen can also be helpful in managing discomfort.

Maintain Oral Hygiene

While it’s important to keep your mouth clean, avoid rinsing vigorously for the first 24 hours to prevent dislodging the blood clot. After the first day, gently rinse your mouth with warm salt water to keep the extraction site clean.

Eat Soft Foods

Stick to a diet of soft foods like yogurt, mashed potatoes, and soup for the first few days. Avoid hot, spicy, and crunchy foods that could irritate the extraction site. Gradually reintroduce solid foods as you heal.

Avoid Straws and Smoking

Using straws and smoking can dislodge the blood clot, leading to dry socket. Avoid these activities for at least a week after the procedure to ensure proper healing.

When to Contact Your Dentist

While most people recover from wisdom teeth extraction without any issues, it’s important to know when to contact your dentist. Seek medical attention if you experience any of the following:

  • Severe or worsening pain that doesn’t improve with medication
  • Persistent bleeding that doesn’t stop after 24 hours
  • Signs of infection, such as fever, pus discharge, or increasing swelling
  • Numbness or tingling that doesn’t go away after a few days

Final Thoughts: Is Wisdom Teeth Extraction Right for You?

Deciding whether to undergo wisdom teeth extraction is a significant decision that should be made in consultation with your dentist. By understanding the potential benefits, risks, and impact on your oral health, you can make an informed choice that best suits your needs.

Remember, each individual’s situation is unique, and your dentist is the best resource for personalized advice and guidance. Whether you need to address existing problems or prevent future complications, wisdom teeth extraction can play a crucial role in maintaining your oral health and overall well-being.
