It’s one of the most common questions patients ask: “Do I need my wisdom teeth out to prevent them from crowding my front teeth?” Countless patients see their lower front teeth moving or overlapping in their early twenties or late teens, right when wisdom teeth (third molars) usually emerge.
But is the connection real? We asked Dr. Aristo Carranza, a premier dental expert in Westfield, NJ, to share his perspective on the evidence.
The Myth: Wisdom Teeth as the “Bully”
The long-held theory is that as wisdom teeth emerge, they exert pressure on the entire dental arch, in a chain reaction, causing crowded or crooked front (anterior) teeth. This idea appears plausible, which explains why it has lasted so long.
However, extensive clinical studies have challenged this assumption.
What the Scientific Evidence Shows
Modern dentistry suggests the link between wisdom teeth and anterior crowding is tenuous at best. Studies comparing patients who had their wisdom teeth extracted versus those who kept them frequently find no significant difference in the onset of anterior crowding.
So, if wisdom teeth aren’t the culprits, what is?
-
Continued Jaw Development: The mandible can continue to grow or change shape subtly into early adulthood, affecting how the teeth fit together.
-
“Mesial Drift”: This is the inherent tendency for teeth to move slowly toward the front of the mouth.
-
Periodontal Health: The condition of your gums and the alveolar bone plays a crucial role in their stability.
-
Not Wearing Your Retainer: In post-orthodontic patients, crowding is frequently the result of teeth shifting back (not wearing a retainer) instead of pressure from wisdom teeth.
When Should Wisdom Teeth Be Removed?
Although wisdom teeth are unlikely to be the primary cause for your front teeth shifting, there are several legitimate health reasons to have them checked and potentially removed by a qualified dentist like Dr. Carranza.
We recommend removal if the wisdom teeth are:
-
Impacted: Trapped in the bone and failing to emerge correctly, which can damage adjacent teeth.
-
Leading to Infection: Leading to pain, swelling, or oral cysts (pericoronitis).
-
Difficult to Clean: Their location far back of the mouth makes them challenging to clean, resulting in decay.
-
Damaging Other Teeth: Pressing on the roots of the second molars.
