What are wisdom teeth?
Wisdom teeth often first appear in young adults between the ages of 17 to 21. They are also called third molars. Because most mouths are too small for 4 more teeth, wisdom teeth often need to be removed. This is called an extraction. It sometimes needs to be done as soon as they erupt or break through the surface.
When should wisdom teeth be removed?
These symptoms may mean that the wisdom teeth have erupted, and should be removed before they cause more serious problems.
The wisdom teeth may be partly erupted. That means the teeth have partly surfaced and have no room in the mouth to come in completely.
Completely impacted teeth have not come through the gum and may never erupt into the mouth. If they are not causing problems or seen as a possible problem, then many dentists will choose to watch them over time. If the wisdom teeth are causing problems or likely to cause problems, most oral health specialists will advise to remove them right away. Early removal will help to prevent problems, such as an impacted tooth that causes the roots of the second molar to resorb.
What problems are often linked to impacted wisdom teeth?
Bacteria and plaque buildup if the molars are partly erupted
A cyst or fluid-filled sac
Jaw and gum disease
Decay or root resorption of the nearby tooth
How are wisdom teeth removed?
To remove the wisdom teeth, your dentist will make a cut or incision through the gum tissue over the tooth. He or she will gently detach the connective tissue between the tooth and the bone. The tooth is then removed and the opening in the gum is stitched closed. Sometimes, some of the bone surrounding the tooth must be removed. The tooth may need to be cut into sections to allow removal.
