Wisdom teeth are the last of the adult teeth that emerge from the gums in the late teens or early twenties, these teeth also known as the third molars. Sometimes they never develop in certain people, while in others up to four teeth are seen one at each end of the upper and lower gums.
Though wisdom teeth generally do not cause problems, sometimes they may not come through the gums properly when there is not enough space for them at the back of the mouth. As a result, they do not grow in a straight line and instead emerge at an angle to fill the available space. These are known as impacted wisdom teeth. Some people are vulnerable to swollen gums around the wisdom tooth, leading to stiffness and soreness of jaw; bad breath and a bad taste as a result of infection at the back of the mouth; pain due to swelling of the face because of infection and a higher risk of tooth decay or gum disease in other teeth.
Impacted wisdom teeth as well as wisdom teeth that have emerged only partially through the gum they will be difficult to clean, they are highly susceptible to dental problems. They need to be extracted only when the impacted teeth are shown to cause serious dental health issues and pain, such as infection; cysts; tooth decay or gum disease this is best evaluated with a visit with your dentist.
