Wisdom Teeth Removal

What Are Wisdom Teeth?

Wisdom teeth are your third set of molars and the last teeth to develop in your mouth. They typically begin forming in early adolescence and attempt to push through the gums between the ages of 17 and 25 — a period historically associated with gaining maturity and "wisdom," which is how they got their name. Most adults develop four wisdom teeth, one in each corner of the mouth, although it is perfectly normal to have fewer than four or, in rare cases, none at all.

From an evolutionary standpoint, wisdom teeth served an important purpose for our distant ancestors. Early humans consumed a diet heavy in raw plants, nuts, roots, and tough meats that required more chewing force and wore down teeth more quickly. A third set of molars provided extra grinding power and compensated for teeth lost to wear and decay. Over thousands of years, as human diets became softer and cooking became universal, jaws gradually became smaller. The teeth themselves, however, did not evolve at the same pace. The result is that modern jaws frequently lack the space to accommodate these additional molars, leading to a host of problems when they try to emerge.

At Glendale Dental Wellness, we monitor wisdom tooth development with regular checkups and digital X-rays. Panoramic radiographs allow us to see the position, angle, and root development of your wisdom teeth long before they attempt to erupt. This early detection enables us to identify potential issues and discuss your options well in advance, rather than waiting for symptoms to develop.

Why Do Wisdom Teeth Need to Be Removed?

It is important to understand that not every person needs their wisdom teeth removed. Some individuals have jaws large enough to accommodate the extra molars, and their wisdom teeth erupt fully, align properly with the opposing teeth, and function without causing any problems. When wisdom teeth come in straight, are easy to keep clean, and do not interfere with neighboring teeth, there is no clinical reason to extract them.

However, the majority of people do not have enough room for wisdom teeth to erupt properly. When space is limited, these teeth can become trapped in the jawbone or gum tissue — a condition known as impaction — or they may emerge only partially, creating an environment ripe for complications. Here are the most common reasons wisdom teeth need to be removed:

• Impaction: The tooth is fully or partially trapped beneath the gum tissue or bone. Impacted wisdom teeth cannot be cleaned, may press against adjacent teeth, and can lead to infection, cysts, or damage to surrounding structures. Impaction is classified as full bony (completely encased in bone), partial bony (partially covered by bone), or soft tissue (covered only by gum tissue).
• Crowding of existing teeth: As wisdom teeth push forward trying to erupt, they can exert significant pressure on the second molars and the rest of the dental arch. This force can shift teeth out of alignment, undo years of orthodontic treatment, and create bite problems that were not present before.
• Pericoronitis: When a wisdom tooth only partially breaks through the gum, a flap of soft tissue remains draped over part of the tooth. Food particles and bacteria become trapped beneath this flap, causing recurrent episodes of painful infection. Pericoronitis can cause swelling, difficulty opening the mouth, and pain that radiates to the ear and jaw. Antibiotics may resolve individual episodes, but the problem tends to recur until the tooth is removed.
• Cysts or tumors: The sac of tissue surrounding an impacted wisdom tooth can fill with fluid and form a dentigerous cyst. Left untreated, these cysts can expand and damage the jawbone, neighboring teeth, and nerves. In rare instances, more serious tumors can develop from the tissue associated with impacted teeth.
• Damage to adjacent teeth: An impacted or angled wisdom tooth can press directly against the root of the second molar in front of it. Over time, this pressure can cause resorption (breakdown) of the adjacent tooth's root, making it weak, painful, and potentially unsavable.
• Difficulty cleaning leading to decay: Even wisdom teeth that fully erupt are positioned so far back in the mouth that they are extremely difficult to brush and floss effectively. This makes them highly susceptible to cavities and gum disease, which can then spread to neighboring teeth.
• Orthodontic treatment planning: If you are beginning or completing orthodontic treatment, your orthodontist may recommend wisdom tooth removal to prevent future shifting that could compromise your results.

Your dentist at Glendale Dental Wellness will evaluate your specific situation and recommend removal only when there is a clear clinical benefit. If your wisdom teeth are healthy, fully erupted, positioned correctly, and able to be cleaned as part of your normal oral hygiene routine, we may recommend simply monitoring them at your regular checkups.

Types of Wisdom Tooth Impaction

When a wisdom tooth cannot fully emerge into the mouth, it is considered impacted. The type of impaction is classified based on the angle at which the tooth is positioned within the jawbone and the degree to which it has erupted through the gum tissue. Understanding the type of impaction helps your dentist plan the surgical approach and anticipate the complexity of the extraction.

Mesioangular Impaction

This is the most common type of wisdom tooth impaction, accounting for roughly 40 to 45 percent of all cases. The tooth is angled forward, tilting toward the front of the mouth and pushing against the second molar. Mesioangular impactions range in difficulty — some are relatively straightforward to remove, while others are deeply angled and require more extensive bone removal.

Distoangular Impaction

In a distoangular impaction, the wisdom tooth is angled toward the back of the mouth, away from the second molar. This is considered one of the more challenging types to extract because the angle of the tooth works against the natural path of removal. Distoangular impactions in the upper jaw tend to be less complex than those in the lower jaw due to differences in bone density.

Horizontal Impaction

A horizontally impacted wisdom tooth lies completely on its side within the jawbone, positioned at a 90-degree angle to the adjacent teeth. This orientation means the tooth is growing directly into the roots of the second molar. Horizontal impactions almost always require surgical extraction with bone removal and tooth sectioning, and they carry the highest risk of complications if left untreated due to the pressure they place on neighboring teeth.

Vertical Impaction

A vertically impacted wisdom tooth is oriented in the correct upright position but remains trapped beneath the bone or gum tissue. The tooth is pointing in the right direction — it simply does not have enough room to erupt through the gum. Vertical impactions that are close to the surface may eventually erupt on their own, but those buried deep in bone typically require surgical removal.

Partial Eruption vs. Full Impaction

Beyond the angle of the tooth, impaction is also described by how much of the tooth has managed to break through. A partially erupted wisdom tooth has pushed through the gum tissue to some degree but has not fully emerged. This is often the most problematic scenario because the opening in the gum creates a pocket where bacteria collect, yet the tooth cannot be properly cleaned. A fully impacted tooth remains entirely beneath the gum and bone. While it may cause no symptoms for years, it can still develop cysts or cause damage to the adjacent molar over time.

The Wisdom Teeth Removal Procedure

Knowing what to expect before, during, and immediately after the procedure helps many patients feel calmer and more prepared. Here is a step-by-step overview of what happens when you have your wisdom teeth removed at Glendale Dental Wellness.

Pre-Operative Evaluation

Before scheduling your extraction, we perform a thorough evaluation. This includes a panoramic X-ray, which provides a complete view of all four wisdom teeth, their roots, their proximity to nerves and sinuses, and the density of surrounding bone. In cases where a wisdom tooth sits very close to the inferior alveolar nerve — the nerve that provides sensation to your lower lip and chin — we may order a cone beam CT scan (CBCT) to obtain a detailed three-dimensional image. This advanced imaging helps us plan the safest and most precise surgical approach.

During this evaluation, we also review your medical history, current medications, and any health conditions that might affect the procedure or your recovery. We discuss what to expect and answer any questions you have so there are no surprises on the day of surgery.

Sedation and Anesthesia Options

Comfort is a priority throughout the procedure, and we offer several levels of anesthesia and sedation so you can choose what works best for you:

• Local anesthesia: Injections that numb the surgical area completely. You remain fully awake and aware but feel no pain at the extraction site. This is appropriate for patients who are comfortable in the dental chair and are having straightforward extractions.
• Nitrous oxide sedation: Also known as laughing gas, nitrous oxide is inhaled through a small mask and produces a relaxed, calm state. Combined with local anesthesia, it is an excellent option for patients who feel mildly anxious about the procedure. The effects wear off within minutes of removing the mask.
• IV sedation: For patients with significant dental anxiety, those undergoing complex extractions, or anyone who simply prefers not to be aware of the procedure, IV sedation provides a deeper level of relaxation. You will be drowsy and may not remember the procedure afterward. A responsible adult must drive you home after IV sedation.

We discuss all available comfort options during your consultation and make a recommendation based on the complexity of your case and your comfort preferences.

The Extraction Process

Once you are fully numb and comfortable, the extraction begins. If the wisdom tooth has partially erupted, the dentist first creates a small incision in the gum tissue to expose the tooth and surrounding bone. For fully impacted teeth, a flap of gum tissue is carefully reflected back to reveal the bone covering the tooth.

If bone is blocking access to the tooth, a controlled amount is removed using a specialized dental handpiece. In many cases, the wisdom tooth is then sectioned — carefully divided into two or more smaller pieces — so that each fragment can be removed through a smaller opening. This technique significantly reduces the amount of bone that needs to be taken away and minimizes trauma to the surrounding tissue.

Each piece of the tooth is elevated and removed from the socket. The site is then thoroughly cleaned and irrigated to remove any debris. If a bone graft is being placed to preserve the bone for a future dental implant, the grafting material is packed into the socket at this point. The gum tissue is repositioned and closed with dissolvable sutures that typically disappear on their own within one to two weeks.

Immediately After the Procedure

Gauze pads are placed over each extraction site, and you will be asked to bite down gently to apply pressure and encourage blood clot formation. If you received IV sedation, you will rest in a recovery area until you are alert enough to be discharged. Before you leave, we provide detailed written post-operative instructions, prescriptions for pain medication and antibiotics if indicated, and a follow-up appointment if needed. A responsible adult should be present to drive you home regardless of your sedation level, as even local anesthesia can leave you feeling somewhat drained.

The entire appointment — from arriving at the office to heading home — typically takes about 90 minutes to two hours when all four wisdom teeth are removed. The actual surgical time is usually 30 to 60 minutes, with the remaining time allocated to preparation, anesthesia, and post-procedure recovery.

Recovery After Wisdom Teeth Removal

Understanding the recovery timeline helps you plan your schedule, stock up on the right foods, and know what is normal as you heal. While every patient heals at their own pace, the following is a general guideline for what to expect after having your wisdom teeth removed.

Day of Surgery

Rest is the most important thing you can do on the day of your procedure. Keep your head elevated, apply ice packs to the outside of your cheeks in 20-minute intervals to limit swelling, and keep biting on gauze as instructed to protect the blood clots forming in your sockets. Stick to cold, soft foods like yogurt, applesauce, and smoothies eaten with a spoon. Take your prescribed pain medication before the numbness wears off so you stay ahead of discomfort. Do not rinse your mouth, spit, use a straw, or smoke — all of these actions can dislodge the blood clot and lead to a painful condition called dry socket.

Days 1 Through 3

Swelling and bruising typically peak around 48 to 72 hours after surgery. This is completely normal and does not mean something is wrong. Continue icing during the first 48 hours, then switch to warm compresses if desired. Begin gentle salt water rinses 24 hours after surgery — half a teaspoon of salt dissolved in a cup of warm water — and let the solution flow gently over the surgical sites after meals. Pain is usually well managed with the prescribed medication. You may notice some stiffness in your jaw, which is caused by swelling in the muscles used for chewing.

Days 4 Through 7

Most patients notice a meaningful improvement during this phase. Swelling begins to subside, jaw stiffness decreases, and pain becomes more manageable — many patients transition from prescription pain medication to over-the-counter ibuprofen. You can begin introducing warmer soft foods like mashed potatoes, scrambled eggs, and soup. Avoid anything crunchy, chewy, or hard that could irritate the healing sites. Light daily activities can resume, but continue to avoid strenuous exercise.

Week 2

By the second week, most patients feel close to normal. Dissolvable sutures will have fallen out or dissolved on their own. The extraction sites are closing over with new gum tissue, though slight indentations may remain. You can gradually return to a regular diet, starting with softer solid foods and working your way back to your usual meals as comfort allows. Most people are back to work, school, and their full routine by this point.

Weeks 3 Through 4

Full soft tissue healing is typically complete by the end of the third or fourth week. The gum tissue over the extraction sites should appear pink and healthy, and any residual soreness should be gone. The bone beneath the surface continues to remodel and fill in over the following months, but this process happens below the gumline and does not affect your daily life.

Should I Remove All Four Wisdom Teeth at Once?

This is one of the most common questions patients ask, and the answer depends on your individual circumstances. In most cases, dentists and oral surgeons recommend removing all four wisdom teeth during a single appointment, and there are several good reasons for this approach.

The primary advantage of removing all four at once is that you only go through the recovery process one time. Healing from wisdom tooth surgery takes about one to two weeks regardless of whether one tooth or four are removed, so having them all done together means one period of downtime instead of multiple. You also undergo anesthesia and sedation only once, which reduces overall risk and is more convenient for patients who prefer IV sedation. From a practical standpoint, it is also more efficient — one pre-operative workup, one day off work or school, and one set of follow-up visits.

There are some situations where removing all four at once may not be the best choice. Patients with certain medical conditions, those taking blood-thinning medications, or individuals who simply feel more comfortable with a staged approach may benefit from having wisdom teeth removed in two separate sessions — typically the upper two teeth at one appointment and the lower two at another, or one side at a time. Removing teeth from one side allows you to chew comfortably on the opposite side during recovery.

At Glendale Dental Wellness, we evaluate the position and condition of each of your wisdom teeth individually and make a recommendation based on what will give you the safest procedure and smoothest recovery. If one or two of your wisdom teeth are not causing problems and are unlikely to in the future, we may recommend leaving them in place while removing only the problematic ones.

When to Consider Wisdom Teeth Removal

Timing matters when it comes to wisdom teeth removal. The ideal window for extraction is during the late teens to early twenties, typically between ages 16 and 25. At this stage, the roots of the wisdom teeth are not yet fully formed — usually only about two-thirds developed — and the surrounding jawbone is less dense than it will be later in life. These two factors make the teeth easier to extract, reduce the likelihood of complications during surgery, and promote faster healing afterward.

One of the most valuable things you can do is have your wisdom teeth evaluated before problems begin. Many patients make the mistake of waiting until they experience pain, swelling, or infection before seeking treatment. By the time symptoms develop, the teeth may have already caused damage to adjacent molars, the impaction may have worsened, and the extraction may be more complex than it would have been years earlier. A proactive evaluation during the teenage years — when wisdom teeth are visible on X-rays but have not yet caused trouble — gives you the advantage of choosing when to have the procedure on your own schedule rather than dealing with an emergency.

That said, adults who still have their wisdom teeth should not assume they are in the clear simply because they have not experienced problems yet. Wisdom teeth can begin causing issues at any age. Some patients develop their first bout of pericoronitis in their thirties or discover a cyst around an impacted tooth during a routine X-ray in their forties. If you are an adult with wisdom teeth that have never been evaluated, it is worth having them checked. Removal is still safe and effective at any age, though recovery may take slightly longer for patients in their thirties and beyond compared to teenagers.

Whether you are a parent scheduling an evaluation for your teenager or an adult who has been putting off dealing with troublesome wisdom teeth, Glendale Dental Wellness can help. We will take the appropriate images, assess your situation honestly, and give you a clear recommendation so you can make an informed decision.

Wisdom Teeth Removal Cost

The cost of wisdom teeth removal varies depending on several factors, and we want to be transparent about what influences pricing so you can plan accordingly. The most significant factor is the degree of impaction. A simple extraction of a fully erupted wisdom tooth costs less than a surgical extraction of a deeply impacted tooth that requires bone removal and tooth sectioning. The number of teeth being removed, the type of anesthesia or sedation used, and whether any additional procedures such as bone grafting are needed also affect the total cost.

Most dental insurance plans cover wisdom teeth removal when it is deemed medically necessary — which includes situations involving impaction, infection, damage to adjacent teeth, cyst formation, or other documented clinical indications. Coverage varies by plan, so we recommend contacting your insurance provider or allowing our front office team to verify your benefits before your appointment. We will provide you with a detailed cost estimate that breaks down what your insurance is expected to cover and what your out-of-pocket responsibility will be.

For patients without insurance or those whose plans do not cover the full cost, we offer flexible financing options to make the procedure accessible. We believe that cost should not be a barrier to necessary dental care, and our team is happy to work with you to find a payment arrangement that fits your budget.
