Wisdom teeth or third molars are the last permanent teeth to erupt. There are usually four of them. These teeth usually erupt between the ages of 16 to early 20’s.
A wisdom tooth is extracted to correct an actual problem or to prevent problems that may come up in the future. When wisdom teeth come in, a number of problems can occur:
- Your jaw may not be large enough for them, and they may become impacted and unable to break through your gums.
- Your wisdom teeth may break partway through your gums, causing a flap of gum tissue to grow over them. Food and germs can get trapped under the flap and cause your gums to become red, swollen, and painful. These are signs of infection.
- More serious problems can develop from impacted teeth, such as infection, damage to other teeth and bone, or a cyst.
