WISDOM TEETH
Long after our primary (baby) teeth have been replaced by permanent teeth, we get third molars - a set of four permanent teeth which come in behind the upper and lower 12-year molars. Third molars are called "wisdom" teeth because they generally erupt between 17 and 21 years of age, when we reach adulthood.
The removal of impacted wisdom teeth and surgical extraction of teeth is quite different from the extraction of erupted teeth. Postoperative problems are not unusual, and extra care must be taken to avoid complications. Click here to find out what is considered normal.
Why Do Wisdom Teeth Cause Problems?
Wisdom teeth that are healthy and properly positioned can be a valuable asset to the mouth. Unfortunately, this is not often the case, and problems develop that require their removal. For example, when the jaw is not large enough to accommodate these teeth, they can become impacted - unable to come in or move into their proper place. They may grow sideways, emerge only part way from the gum, or remain trapped beneath the gum and bone.
Impaction occurs most often in the third molars of the lower jaw. After examining your mouth and taking X-rays, your dentist will discuss whether your wisdom teeth should be removed.
Why Are Wisdom Teeth Removed?
Extraction of third molars can protect the overall health of the mouth. It is generally recommended when the following conditions occur
1. - Wisdom teeth only partially erupt. This leaves an opening for bacteria to enter around the tooth and cause an infection. Pain, swelling, jaw stiffness and general illness can result.
2. - Impacted wisdom teeth may continue growing without enough room, damaging adjacent teeth.
Why Remove the Teeth Early?
People between the ages of 16 and 19 should have their wisdom teeth evaluated. If they need to be removed, it should be considered before age 20 when generally fewer complications occur. At a younger age, tooth roots are not fully developed, the surrounding bone is softer, and there is less chance of damaging nearby nerves or other structures. There is also less surgical risk and healing is generally faster.
Extractions of wisdom teeth may be performed by a general dentist. If your dentist anticipates any special care will be needed he, or she, may refer you to an oral and maxillofacial surgeon. An oral and maxillofacial surgeon is a dentist who specializes in surgery and the removal of wisdom teeth.
What to Expect of the Procedure
Before surgery, your dentist will explain what to expect, have you sign a consent form and give you personalized instructions to follow. Keep in mind these general items to help your surgery go smoothly.
Wear loose, comfortable clothing and arrange to have someone be with you after surgery. Extractions can be performed under local or general anesthesia; In Our office, to help you relax before and during the procedure, we could give you some medication and also could use laughing gas. If gas is going to be used, be aware of an extra charge and you should not eat for a minimum of 6 hours; otherwise, make sure you eat well before the surgery. The procedure usually takes less than 45 minutes. We also recommend for most cases, to fill the space of the extraction with bone grafting material for a better healing and maintenance of the jaw bone.
Following surgery, you may experience some swelling and mild discomfort, which is part of the normal healing process. Cold compresses for the first 24 hours can help decrease the swelling and pain, and medication prescribed by your dentist can help decrease the pain. You may be instructed to drink only clear liquids following surgery and later progress to soft foods.
Some patients experience numbness or tingling following surgery. Normal sensation usually returns in a period of time. Occasionally, a dry socket occurs when the blood clot breaks down earlier than normal. A dressing placed in the socket protects it until the socket heals.
Talk with your dentist about any questions that you have. It is especially important to let your dentist know, before surgery, of any illness that you have and medications that you are taking. If your general dentist has referred you to a specialist, they will both work together to provide you with the best and most efficient care. Keeping your teeth healthy - to a wise old age - is your dentist's primary concern.
It is important to know that the procedure is usually done in one hour and that you need to take off work or school for some days.
