wisdom teeth
Third molars are commonly referred to as wisdom teeth. They are usually the last teeth to develop and are located in the back of your mouth, behind your second molars. Their development is usually completed between the middle teenage years and early twenties, a time traditionally associated with the onset of maturity and the attainment of wisdom.
By the age of 18, the average adult has 32 teeth; 16 teeth on the top and 16 teeth on the bottom. Each tooth in the mouth has a specific name and function. The teeth in the front of the mouth (incisors, canine, and bicuspid teeth) are ideal for grasping and biting food into smaller pieces. The back teeth (molar teeth) are used to grind food up into a consistency suitable for swallowing.
The average mouth is made to hold only 28 teeth. It can be painful when 32 teeth try to fit in a mouth that holds only 28 teeth. These four other teeth are your third molars, also known as “wisdom teeth.”
What is an impacted tooth?
Although most people develop and grow 32 permanent adult teeth, many times their jaws are too small to accommodate the four wisdom teeth. When inadequate space prevents the teeth from erupting they are called impacted wisdom teeth. This indicates their inability to erupt into the proper position for chewing and cleaning. Impaction wisdom teeth are classified as soft tissue, partial bony and complete bony based on the tissue that is overlying the tooth.
Why should I have my wisdom teeth removed?
If you do not have enough room in your mouth for your third molars to fully erupt, a number of problems can happen. Impacted wisdom teeth should be removed before their root structure is fully developed. In some patients it is as early as 12 or 13, and in others it may not be until the early twenties. Problems tend to occur with increasing frequency after the age of 30. Some of the possible problems related to not removing your wisdom teeth include:
Localized Periodontal Disease
The most frequent clinical problem we see is pericoronitis, (a localized gum infection). Without enough room for total eruption, the gum tissue around the wisdom tooth can become irritated and infected, resulting in recurrent pain, swelling, and problems with chewing and/or swallowing.
Dental caries
With chronic food impaction to the crown of wisdom teeth secondary to inability to floss and maintain proper hygiene, cavities can develop just as other teeth in the oral cavity. The combination of difficult access for restorative dentistry and nonfunctional status, extraction is the recommended treatment.
damage to adjacent teeth
If there is inadequate room to clean around the wisdom tooth debris and plaque can accumulate. The tooth directly in front, the second molar, can be adversely affected resulting in dental caries, gum disease and bone loss around the tooth due to plaque from food impaction and excessive force of eruption.
cyst formation
Non-infectious diseases may also arise in association with an impacted wisdom tooth. Cysts are fluid-filled “balloons” inside the jaw bone that develop as a result of impacted teeth and slowly expand destroying adjacent jaw bone and occasionally teeth. Although rare, tumors can be associated with the delayed removal of wisdom teeth.
What if I don’t have my wisdom teeth removed as a teenager or young adult?
As wisdom teeth develop, the roots become longer and the jaw bone more dense. When it is necessary to remove impacted wisdom teeth in your thirties, forties or beyond, the post-operative course can be prolonged and there is a higher complication rate. Treating these complications is often more difficult and less predictable than with a younger patient. Healing may be slower and the chance of infection can be increased. If your impacted wisdom teeth are not removed in your teenage years or early in your twenties and they are completely impacted in bone, it may be advisable to wait until a localized problem (such as cyst formation or localized gum disease and bone loss) develops. In general, you will heal faster, more predictably and have fewer complications if treated in your teens or early twenties.
