6 Ways Removing Wisdom Teeth Can Help Improve Oral Health
You’ve probably heard of the term “wisdom teeth.” It’s the common name for the third set of molars — the last permanent teeth to emerge, usually between ages 17–25. Some people don’t have all their wisdom teeth, while others have none. Many of those who do eventually have them removed.
But why remove wisdom teeth at all? Can they affect orthodontic treatment like braces or Invisalign? Do they shift teeth after braces? Patients often have questions like these and Petrous Orthodontics has answers.
Do you have to have your wisdom teeth removed? Not always. Is it sometimes a smart idea? Yes, and here’s why.
Wisdom teeth are the final set of molars to erupt, signaling the end of permanent tooth development. They’re unique to adults — primary or “baby” teeth never include them. Most people have four: one in each corner of the mouth, as well as on the top and bottom.
However, not everyone gets the complete set. Approximately 20–25% of people develop only 1–3, and around 35% have none. Genetics play a role — if your parents were missing wisdom teeth, you may be too.
Years ago, it was standard to remove wisdom teeth before or after braces, based on the belief that they would cause crowding. However, updated research shows that post-braces shifting is more often caused by not wearing your retainer than by the emergence of wisdom teeth.
Still, that doesn’t mean wisdom teeth can’t cause problems. Whether or not you’re in treatment, they may impact your oral health long term.
It’s a common myth that wisdom teeth “push” other teeth out of place. While they can place some pressure on nearby molars, your teeth are more likely to shift because of:
Your lower jaw, in particular, continues to grow forward as you age. Later in life, bone density can decrease, which affects how teeth sit and align. This is why wearing your retainers — especially at night — is so important for long-term results.
Is there a reason to remove wisdom teeth after wearing braces? Sometimes, yes — but not simply because you had braces. There are other factors that your orthodontist will consider.
1. They’re Growing at the Wrong Angle
Wisdom teeth often erupt at odd angles because of limited space. Some point sideways toward neighboring molars, some angle outward, and some try to erupt while still lying flat. These positions can irritate surrounding tissue or affect nearby teeth.
In most cases, removal is safer and more effective than trying to reposition the tooth.
2. They’re Impacted (Stuck in the Jaw)
Impacted wisdom teeth are those that fail to erupt fully. They often remain stuck beneath the gumline or jawbone, which can lead to pain, swelling, or infection.
If your wisdom tooth is impacted, it won’t “come in later.” Your orthodontist will likely recommend removal to avoid complications.
3. They Complicate Braces or Invisalign
Wisdom teeth can press tightly against second molars. This rarely causes crowding, but it can make orthodontic treatment more difficult — especially when trying to place brackets or aligners.
If wisdom teeth interfere with your braces or Invisalign, your orthodontist may recommend removing them to keep your treatment plan smooth and effective.
4. They Irritate the Gums or Jawbone
Wisdom teeth that are poorly positioned can trap gum tissue or make it more difficult to clean the back of your mouth. This increases the risk of gum disease or infection.
In rare cases, a fluid-filled sac called a cyst may form near the tooth. Cysts can damage nearby bone or teeth if left untreated. Removing the wisdom tooth is often the best preventive step.
5. They’re Hard to Keep Clean
Wisdom teeth that are partially erupted or tilted are harder to brush and floss around. Food and plaque easily collect, leading to tooth decay, gingivitis, or deeper periodontal problems.
If you’ve had repeat dental issues near your wisdom teeth, removing them may help protect your smile and simplify your hygiene routine.
6. They Could Cause Future Problems
Even if they aren’t bothering you right now, wisdom teeth can become problematic later. As we age, surgeries and healing become increasingly complex. That’s why many orthodontists recommend early removal as a preventive measure, especially if the teeth are already showing signs of poor positioning.

Not always. If they aren’t causing issues or interfering with your bite, they can often stay. Your orthodontist will evaluate based on X-rays and overall alignment.
They can cause mild pressure, but teeth are more likely to shift due to neglect of the retainer or growth of the jaw over time.
It means the tooth is stuck beneath the gum or bone and hasn’t erupted properly. Impacted teeth may cause pain, swelling, or infection and are usually removed.
Yes. Healing tends to be faster and easier before your late 20s. That’s why proactive removal is often recommended.
