Many people hear that their wisdom teeth need to be removed, but not everyone understands why. While some wisdom teeth grow in without causing any issues, others can lead to pain, infection, crowding, and damage to surrounding teeth. In some cases, problems may develop before the teeth have even fully emerged.
Understanding when to have wisdom teeth removed can help you avoid complications and make informed decisions about your oral health. In this article, we’ll discuss the most common reasons for wisdom tooth removal, the signs to watch for, and the age at which extraction is often recommended.
What Is A Wisdom Tooth?
Wisdom teeth are the final set of adult teeth that grow at the very back of your mouth, also known as your third molars. They typically emerge between the ages of 15 and 25, arriving later than your other adult teeth.
The purpose of these teeth was that in the past, humans had larger jaws and required the extra molars to grind down tough meat and other foods. They were a backup when other teeth wore out or were lost, but now, due to natural evolution, they no longer serve a purpose.
If wisdom teeth erupt properly and are healthy, they can function like any other molar and help support normal chewing function.
Reasons for Wisdom Tooth Removal
Not everyone needs to have their wisdom teeth removed. However, when these third molars do not have enough room to emerge properly or begin causing oral health issues, your dentist may recommend extraction.
Impacted Wisdom Teeth
One of the most common reasons for wisdom tooth removal is impaction. An impacted wisdom tooth is unable to fully emerge through the gums because there is not enough space in the mouth. Instead, the tooth may remain trapped beneath the gums, grow at an angle, or press against neighbouring teeth.
Impacted teeth can lead to pain, swelling, infection, inflammation, and damage to nearby teeth. In some cases, they may also result in cysts developing around the impacted tooth. Removing impacted wisdom teeth early can help prevent these complications and protect your overall oral health.
Pain or Discomfort
Persistent pain at the back of the mouth is often a sign that a wisdom tooth may need to be removed. As wisdom teeth attempt to erupt, they put pressure on surrounding teeth and gums, resulting in discomfort when chewing, jaw soreness, headaches, or a feeling of pressure in the mouth.
While occasional discomfort can occur as wisdom teeth emerge, ongoing pain should be evaluated by a dentist to determine whether extraction is necessary.
Infection, Gum Disease, and Tooth Decay
Partially erupted wisdom teeth can create pockets between the tooth and gum tissue where food particles and bacteria become trapped. These areas are difficult to clean effectively with regular brushing and flossing, which makes them more prone to infection, plaque buildup, cavities, and decay.
Patients with problematic wisdom teeth may experience swollen, tender gums, bad breath, and recurring infections. If left untreated, these issues can contribute to gum disease and affect the health of the neighboring teeth as well. In some cases, decay or infection may spread to adjacent molars, leading to more extensive dental treatment.
Crowding or Shifting Teeth
When there is not enough room in the jaw for wisdom teeth to erupt, they can place pressure on surrounding teeth. This may contribute to crowding or shifting, especially in patients who have already undergone orthodontic treatment.
Although wisdom teeth are not always the cause of tooth movement, your dentist may recommend removal if they believe the teeth could negatively impact your bite or alignment.
At What Age Should Wisdom Teeth Be Removed?
Wisdom teeth are typically evaluated between the ages of 15 and 22. If removal is necessary, many dentists recommend extraction during the late teenage years or early twenties. At this stage, the roots have not fully formed, and the jawbone is less dense, which makes the procedure much easier and your recovery time significantly faster.
That said, wisdom teeth do not always need to be removed. If they have fully erupted, are properly aligned, and can be cleaned effectively, they may not require extraction. The best time to remove wisdom teeth depends on your individual oral health needs and your dentist’s recommendations.
