They are impacted
When your wisdom tooth prevents from emerging out of your jawbone due to insufficient space in your mouth, it gets impacted and can cause severe pain and discomfort while eating.
They grow in a wrong angle
It can either grow towards your next tooth or towards the back of your mouth, causing pain and orthodontic complications.
Wisdom tooth is often unapproachable by your toothbrush and due to lack of brushing it might become a home for gum disease, bad breath, and dental infections. Thus, it needs to get removed.
