When it comes to wisdom teeth, many people assume they’ll need to come out eventually—but is that always the case? If your dentist has brought up the topic of wisdom tooth removal, you might be wondering whether it’s truly necessary.
In this blog, we’ll walk you through what wisdom teeth are, why they sometimes cause problems, and when removal is actually recommended.
What Are Wisdom Teeth?
Wisdom teeth are your third molars—usually the last set of adult teeth to emerge, typically between the ages of 17 and 25. Most people develop four wisdom teeth, although some may have fewer, or none at all.
In many cases, the modern jaw doesn’t have enough space to accommodate these extra molars, which can lead to complications.
Do Wisdom Teeth Always Need to Be Removed?
Not necessarily. Wisdom teeth only need to be removed if they pose a problem now—or are likely to cause issues in the future. If they erupt normally, are properly aligned, and can be easily cleaned, your dentist may suggest leaving them in place.
However, for many people, removal is recommended due to the risk of impaction, infection, and damage to nearby teeth.
Common Reasons for Wisdom Tooth Removal
Here are some of the most common reasons your dentist may recommend extraction:
1. Impaction
Wisdom teeth can become impacted—trapped beneath the gum or growing at an angle. Impacted teeth can press against adjacent teeth, causing pain, swelling, and even shifting.
2. Pain or Discomfort
Persistent discomfort at the back of your mouth may be a sign your wisdom teeth are pushing through incorrectly or becoming infected.
3. Infection or Gum Disease
Partially erupted wisdom teeth can be hard to clean, making them more prone to bacterial build-up, which may lead to gum disease or recurring infections.
4. Tooth Decay
Wisdom teeth that are difficult to brush and floss can develop cavities or increase the risk of decay in nearby molars.
5. Cysts or Jaw Damage
In rare cases, cysts may form around impacted wisdom teeth. These fluid-filled sacs can damage jawbone, nerves, and neighbouring teeth if left untreated.
When Might Wisdom Teeth Be Left Alone?
If your wisdom teeth:
- Erupt fully and in alignment
- Don’t cause pain or infection
- Are not crowding or damaging nearby teeth
- Can be cleaned as part of your normal oral hygiene routine
…then your dentist may recommend simply monitoring them during regular check-ups.
How Will I Know If Mine Need to Come Out?
The best way to know is to visit your dentist for an oral examination and X-ray. This allows them to assess the position of your wisdom teeth and determine if any future issues are likely.
Even if your wisdom teeth aren’t causing pain now, they might be growing in a way that could lead to problems down the track.
Should I Delay Wisdom Tooth Removal?
Delaying removal can sometimes lead to more complex procedures later on. In general, younger patients tend to recover faster and have fewer complications. That’s why many dentists recommend early removal before problems develop.
Can wisdom teeth cause headaches or ear pain?
Yes, impacted or misaligned wisdom teeth can exert pressure on surrounding tissues, leading to discomfort that may manifest as headaches or ear pain.
Do all four wisdom teeth need to be removed at once?
Not necessarily. The decision to remove all four wisdom teeth depends on their position, development, and potential to cause problems. Some dentists recommend removing all at once to prevent future issues, while others may suggest a more conservative approach.
Can Wisdom Teeth Grow Back After Removal?
Once a wisdom tooth has been extracted, it will not grow back. Humans are only naturally equipped with one set of adult (permanent) teeth, including the third molars—commonly known as wisdom teeth. However, in rare cases, individuals may develop extra teeth beyond the usual 32. These are called supernumerary teeth, and in the molar region, they can resemble additional wisdom teeth. If such teeth emerge after initial extractions, it may appear as though the wisdom tooth has “grown back,” when in fact, it’s a different tooth altogether. These rare cases are usually detected via dental X-rays and may require monitoring or removal if they pose issues.
When Is the Best Time to Remove Wisdom Teeth?
Dentists generally advise having wisdom teeth assessed between the ages of 17 and 25. This is typically when the teeth begin to emerge or show signs of potential impaction on X-rays. Removal during this period is often preferred because the roots are not yet fully developed, and the surrounding bone is softer, making the procedure less complex and the recovery quicker. While some people may never need removal, early evaluation helps prevent future problems like crowding, infection, or cyst formation.
What to Expect During Wisdom Tooth Removal Recovery
Recovery times can vary depending on the number of teeth removed, whether they were impacted, and your general health. Most people feel significantly better within 3 to 7 days, although complete healing of the extraction site may take several weeks. The first 48 hours are typically the most uncomfortable, with swelling, mild bleeding, and jaw stiffness being common. Following your dentist’s aftercare instructions—such as resting, avoiding certain foods, and keeping the area clean—can promote faster healing and reduce the risk of complications like dry socket. Younger patients often experience a smoother recovery due to quicker tissue regeneration and less complex extractions.
