Once you're in your late teens and early twenties, you may think you've accomplished all your major oral health milestones until you discover your wisdom teeth are coming in. Some get only one or two of their wisdom teeth, while some don't grow any at all. For various reasons, others have no problems with wisdom teeth crowding or impacting their other teeth and may keep their wisdom teeth for life.
Don't worry; your dentist is likely following your wisdom teeth' progress during your regular dental checkups. They will be checking to see if your wisdom teeth have enough room or if they will become impacted. According to the American Dental Association (ADA), an impacted tooth is one that is trapped in your jaw or under your gums and gets blocked as it pushes through the gum into your mouth when it's trying to erupt.
