Wisdom Teeth and Clear Aligners: Are They Compatible?

Do wisdom teeth need to be extracted before aligner treatment? What impact do they have on orthodontic results? Clear answers.

Wisdom teeth — or third molars — raise many questions during clear aligner treatment. Do they need to be extracted? Can they move the other teeth? Should they be included in the treatment? Here are the clear answers you are looking for.

Do wisdom teeth really move the other teeth?

It is a persistent myth: wisdom teeth push on the other teeth and cause crowding in the front. Recent scientific studies have largely nuanced this claim. Incisor crowding is a multifactorial phenomenon (jaw growth, habits, relapse) and cannot be attributed solely to wisdom teeth. However, in some cases, their presence and position can indeed exert pressure.

When should wisdom teeth be extracted before treatment?

• When they are impacted (stuck in the bone) and visibly pressing on adjacent molars
• When their eruption is expected during the treatment period and risks disrupting the plan
• When they are partially erupted and likely to cause repeated infections
• When the treatment plan requires space that the wisdom tooth occupies or will occupy

When can wisdom teeth be kept?

If wisdom teeth are fully erupted, well-positioned, healthy and not pressing on adjacent teeth, there is no reason to extract them before or during aligner treatment. Your Infinity Aligner dentist will assess their situation on the panoramic X-ray taken at the start of treatment.

Conclusion

The question of wisdom teeth should be systematically addressed at your initial consultation with a certified Infinity Aligner dentist. A panoramic X-ray will assess their position, condition and potential impact on your treatment. It is a personalised decision — there is no universal answer.
