By the time wisdom teeth begin to emerge, most people already have a full set of teeth. That means there usually isn’t room for wisdom teeth in the mouth, and they’re likely to push the other teeth out of place — and cause pain in the process.
Wisdom teeth are also likely to become impacted, meaning they grow at an angle toward the other teeth. Impacted wisdom teeth are even more likely to push the rest of your teeth out of alignment and cause other dental health issues.
When your teeth are pushed together by the emergence of wisdom teeth it isn’t just a cosmetic problem. Teeth overlapping or putting pressure on each other can make those teeth more likely to crack or chip, causing additional problems and needing repair.
A packed mouth can also make dental hygiene more challenging. If teeth are pressed too close together it can be difficult or impossible to floss properly, leading to additional decay over time.
