Why should wisdom teeth be removed?
When wisdom teeth erupt into the mouth and align properly within the arch, removal of these teeth are unnecessary. Unfortunately, this does not generally happen. The extraction of wisdom teeth is necessary when they do not properly erupt within the mouth. They can grow in various orientations, may partially emerge from the gum, or may remain trapped beneath the gum and bone. Impacted teeth can take many awkward positions in the bone as they attempt to erupt into the mouth.
Poorly positioned or impacted wisdom teeth can cause many problems. When they are partially erupted, the opening around the tooth allows bacterial growth leading to infection. Moreover, the pressure from erupting wisdom teeth can cause shifting of your primary teeth eventually disrupting the natural alignment of your smile.
Cysts or tumors may form around the impacted wisdom tooth causing destruction of the adjacent jaw bone and teeth. Removal of the offending impacted wisdom tooth or teeth usually remedy these problems.
Early removal is recommended to avoid future problems and to decrease the surgical risk. The age group which wisdom teeth are usually removed are in the late teens and early twenties. The reason for this is that the wisdom teeth are usually only two-thirds formed; this allows removal with minimized surgical trauma, and the risks are minimized at this point. |
