Wisdom teeth are a common occurrence among people. They are a set of third molars which appear between the ages of seventeen and twenty-five. Frequently, they are not a problem but, when they affect other teeth, they should be extracted. Wisdom teeth can cause problems for the other teeth in a person’s mouth before they come through the surface or when they are impacted.
The majority of people have four wisdom teeth but many people also have less. If a person does not have four teeth, he or she is said to have hypodontia. This is not a problem. If a person has more then four wisdom teeth, he or she is said to have supernumerary teeth.
The name “wisdom tooth” is frequently thought to come from the more advanced age when these teeth come in. A person is, generally speaking, more wise at seventeen than at twelve, when the majority of teeth have come in.
Impacted teeth, come in a number of varieties. The most common variety of impaction is mesioangular impaction. This type is present in 44% of all impacted cases. It involves the impacted teeth being angled towards the front of the mouth.
Vertical impaction, the second most common type, is present in 38% of all cases. This type of impaction means that the tooth does not go through the gum line completely. The tooth is fully formed but just doesn’t quite make it.
Distoangular impaction and horizontal impaction are relatively rare. Distoangular impaction is present in just 6% of all cases. The tooth is angled towards the back of the mouth, rather than vertically. In horizontal impaction, present in a mere 3% of cases, the tooth is fully rotated ninety degrees forward. Basically, the tooth is growing into the roots of the second molar.
When performing extractions on impacted teeth, it is easier to remove distoangularly impacted wisdom teeth from the upper jaw and mesioangularly impacted teeth from the lower jaw. It is more difficult to remove mesioangularly impacted teeth from the upper jaw and distoangularly impacted teeth from the lower jaw.
An impacted tooth can also be characterized by whether or not it has moved out of the jaw. If the tooth is still completely encased in jaw, it is called a boney impaction. If the tooth has managed to break free of the jaw, it is a soft-tissue impaction.
Wisdom teeth are generally not extracted on a whim. They are extracted to correct an actual problem or to prevent future problems from occurring. There are two broad reasons to extract teeth. One, they are already impacted. Two, they will become a problem if they are not extracted.
An extraction should only be performed by a dental professional who has proper training and experience with removing wisdom teeth. For more information on preventative and restorative dental procedures, please visit http://www.drbagai.com/.
