If the wisdom teeth are properly aligned, fully erupted and can be properly cleaned, there is no need to remove them. However, if they are partially or fully impacted, emerge sideways, or push on the surrounding teeth, many complications can arise. Infection, shifting teeth, and even cysts or tumors could occur. Promptly removing problematic wisdom teeth before complications set in is considered the best course of action. That’s why a thorough evaluation by a specialist is essential.
