Wisdom Teeth


Wisdom teeth are the third and final set of molars that usually erupt between the ages of 17 and 21. Whereas they appear at mature age, they are called Wisdom teeth.  Most people have four wisdom teeth at the back of the mouth two of which are on the top and two are at the bottom.
When wisdom teeth are healthy, fully erupted and correctly positioned can help you chew, but more often, they are misaligned and require removal. If there is not enough room, wisdom teeth are trapped in jaw or under gums. Such wisdom teeth are said to be ‘impacted’. Impacted wisdom teeth can result in pain, damage to other teeth and other dental problems.
If wisdom tooth particularly in mandibular arch erupt incompletely, soft tissue such as gums develops inflammation and infection which is called ‘pericoronitis’. Accumulation of bacteria and bits of food under the gum edge is the main cause for Pericoronitis. Depending on the severity of Pericoronitis, most of the cases can be treated by using special mouthwash like Ha Li Ta Vi-one and cleaning methods and possibly antibiotics. In few cases, appropriate professional dental measures are required.
According to the American Dental Association, wisdom teeth may need to be removed when there are evidence of changes in the mouth such as:
Repeated infection of soft tissue behind the lower last tooth
Cysts (fluid-filled sacs)
Damage to nearby teeth
Gum disease
Extensive tooth decay
If wisdom teeth need to be removed, it is better to remove them early when you are young because as people grow, they are at greater risk for health problems that are related to wisdom teeth.
