When Is Wisdom Teeth Removal Necessary?

Wisdom Teeth Removal Scarborough: Do They Always Need to Come Out?

Wisdom teeth — the third set of molars that typically emerge between the ages of 17 and 25 — are one of the most commonly discussed topics in dentistry. Many people assume that wisdom teeth removal Scarborough dentists recommend is always necessary, but that is not always the case. Some wisdom teeth grow in properly, align well with the rest of your teeth, and cause no problems at all. When this happens, there is no clinical reason to remove them.

However, for a significant number of people, wisdom teeth do cause trouble. They may come in at an angle, get trapped beneath the gums, crowd neighbouring teeth, or develop infections. At Pickering Square Dental, we carefully evaluate each patient’s wisdom teeth using digital X-rays and clinical examination to determine whether extraction is truly necessary or whether monitoring is the better approach.

When Wisdom Teeth Removal Is Necessary

While not every wisdom tooth needs to come out, there are several clear situations where extraction is the recommended course of action:

Impaction: This is the most common reason for wisdom teeth removal. An impacted wisdom tooth is one that does not have enough room to emerge normally. It may be fully trapped beneath the gumline (full bony impaction), partially emerged (partial impaction), or growing sideways into the neighbouring molar. Impacted teeth can cause pain, swelling, and infection, and they increase the risk of cysts or tumours forming around the tooth root.

Pericoronitis (gum infection): When a wisdom tooth is partially erupted, a flap of gum tissue often covers part of the crown. Food and bacteria get trapped beneath this flap, leading to a painful infection called pericoronitis. Symptoms include swollen, red gums behind the last molar, a bad taste in the mouth, difficulty swallowing, and sometimes fever. Recurrent pericoronitis is a strong indication for extraction.

Crowding and shifting: Emerging wisdom teeth can push against your second molars, causing them to shift. This can undo years of orthodontic work and lead to misalignment. While the degree of crowding wisdom teeth cause is debated in dental research, your dentist can assess your specific situation with X-rays.

Tooth decay: Wisdom teeth sit far back in the mouth, making them difficult to clean properly with a toothbrush and floss. This makes them particularly vulnerable to cavities. If a wisdom tooth develops significant decay, extraction is often more practical than restoration, especially if the tooth is partially impacted or poorly positioned.

Cysts and tumours: In rare cases, a sac of fluid (cyst) can form around an impacted wisdom tooth. Over time, this cyst can enlarge and damage the jawbone, neighbouring teeth, and nerves. Early removal of the impacted tooth prevents these complications.

Damage to adjacent teeth: A wisdom tooth growing at an angle can press against the second molar, causing resorption (breakdown) of the neighbouring tooth’s root. This can compromise the health of an otherwise perfectly sound tooth.

Warning Signs That Your Wisdom Teeth May Be Causing Problems

Many wisdom tooth problems develop gradually, and some people do not notice symptoms until the issue has become serious. Watch for these warning signs:

• Pain or tenderness at the back of your jaw, especially behind your last molar.
• Swollen, red, or bleeding gums around the wisdom tooth area.
• Difficulty opening your mouth fully or stiffness in your jaw.
• A persistent bad taste in your mouth or bad breath that does not improve with brushing.
• Swelling in the cheek or jaw on one side of your face.
• Headaches or earaches that seem to originate from the back of your jaw.
• Difficulty chewing or pain when biting down on the affected side.

If you experience any of these symptoms, schedule an appointment promptly. Early evaluation can prevent more serious complications like spreading infection or damage to adjacent teeth. The Ontario Dental Association recommends regular dental checkups that include monitoring wisdom tooth development, especially for patients in their late teens and early twenties.

The Wisdom Teeth Extraction Procedure

Understanding what happens during the procedure can help ease any anxiety you may feel. Here is what to expect:

Consultation and imaging: Your dentist will take panoramic X-rays or a cone beam CT (CBCT) scan to see the exact position of your wisdom teeth, the shape of their roots, and their relationship to surrounding structures like nerves and sinuses. This information guides the extraction plan.

Anaesthesia options: Depending on the complexity of the extraction and your comfort level, your dentist may recommend local anaesthesia (freezing the area), nitrous oxide (laughing gas) for mild relaxation, oral sedation for moderate anxiety, or IV sedation for deeper relaxation. Dr. Marvin Lean and the team at Pickering Square Dental discuss all options with you to find the best fit.

The extraction: For a fully erupted wisdom tooth, the procedure is similar to any other tooth extraction — the dentist loosens the tooth with an elevator instrument and removes it with forceps. For impacted teeth, a small incision is made in the gum tissue, and in some cases, a small amount of bone around the tooth is removed. The tooth may be divided into sections for easier removal. The entire process typically takes 20 to 45 minutes per tooth.

Closure: After the tooth is removed, the extraction site is cleaned, and dissolvable stitches may be placed to close the gum tissue. Gauze is placed over the site to control bleeding and help a blood clot form.

Recovery After Wisdom Teeth Removal

Recovery from wisdom teeth extraction typically takes one to two weeks, with the first three to four days being the most uncomfortable. Here is a general timeline and care tips:

Day 1 (day of surgery): Bite on gauze for 30 to 45 minutes to stop bleeding. Apply ice packs to your cheeks — 10 minutes on, 10 minutes off — to minimize swelling. Rest with your head elevated. Take prescribed pain medication before the anaesthesia wears off. Eat only soft, cool foods like yogourt, applesauce, or smoothies (do not use a straw — the suction can dislodge the blood clot and cause a painful condition called dry socket).

Days 2 to 3: Swelling typically peaks on the second or third day. Continue with ice packs and anti-inflammatory medication. Gently rinse with warm salt water (half a teaspoon of salt in a cup of warm water) after meals to keep the extraction sites clean. Avoid vigorous rinsing or spitting.

Days 4 to 7: Swelling and bruising begin to subside. You can gradually introduce softer solid foods like pasta, scrambled eggs, and mashed potatoes. Continue salt water rinses and gentle brushing, avoiding the extraction sites directly.

Days 7 to 14: Most patients feel significantly better by the end of the first week. Stitches dissolve on their own (if dissolvable ones were used). You can usually return to your normal diet and activities, though the extraction sites may take several weeks to fully heal beneath the surface.

Frequently Asked Questions About Wisdom Teeth Removal

At what age should wisdom teeth be evaluated?

Most dentists recommend evaluating wisdom teeth between the ages of 16 and 19. At this stage, the teeth are still developing, roots are not fully formed, and the bone is less dense — all of which make extraction easier and recovery faster if removal is needed. However, wisdom teeth can be removed at any age if problems develop.

Is it painful to have wisdom teeth removed?

The procedure itself is not painful because anaesthesia numbs the area completely. If you opt for sedation, you may not even remember the procedure. After surgery, some discomfort and swelling are normal for the first few days, but these are manageable with prescription or over-the-counter pain medication. Most patients report that the recovery is more uncomfortable than the actual extraction.

What is dry socket and how do I prevent it?

Dry socket (alveolar osteitis) occurs when the blood clot at the extraction site is dislodged or dissolves too early, exposing the underlying bone and nerves. It causes intense, throbbing pain that typically starts two to four days after extraction. To prevent dry socket, avoid using straws, smoking, spitting forcefully, or rinsing vigorously for at least 72 hours after surgery. If you suspect dry socket, contact your dentist immediately — the condition is treatable with medicated dressings.

Can I keep my wisdom teeth if they are not causing pain?

Possibly, yes. If your wisdom teeth are fully erupted, properly aligned, healthy, and cleanable, your dentist may recommend keeping them and monitoring them at regular checkups. However, the absence of pain does not always mean the absence of a problem — impacted teeth can silently cause damage to adjacent teeth or develop cysts without obvious symptoms. Regular X-rays help your dentist catch these hidden issues.

How many wisdom teeth can be removed at once?

All four wisdom teeth can be removed in a single appointment if necessary. In fact, many patients prefer to have all problematic wisdom teeth removed at once to avoid multiple surgeries and recovery periods. Your dentist will discuss the best approach based on your specific situation and comfort level.
