Impacted Wisdom Teeth
The third molars are called “wisdom teeth.” Usually, they come in between the teen years and early twenties. There are four wisdom teeth that are on each side of your upper and lower jaw. One or two may not develop at all or become impacted. Impacted means that the wisdom tooth is trapped underneath the gum and bone tissue. Impacted teeth often cause other teeth to shift and usually need to be extracted. Your dentist can tell if these teeth are coming in properly by looking at x-rays taken over time.
