Wisdom Tooth Removal: What Is a Dry Socket?

After a wisdom tooth has been extracted, the socket is filled with a blood clot. Slowly, the clot shrinks and fills in. That is, a skin or a covering with tissue similar to the rest of the mouth (mucous membrane) begins to cover the clot and the tissue in the clot area is ingrown by bone cells and tissue cells. Eventually, the area shrinks and the socket is eliminated and replaced by firm tissue, and the depth of the socket fills with bone. The healed area usually is narrower than the site of the original wisdom tooth.

The pain following a wisdom tooth extraction usually lasts no more than a day or two, at the most. If the clot breaks down or is washed away, the protective covering of the exposed bone is lost and the bone can be exposed to the mouth bacteria. This painful condition is known as dry socket. One of the features of its presence is that wisdom tooth post-extraction pain persists longer than a couple of days and can be quite severe.

Though the causes are not known with certainty, some factors seem to predispose individuals towards a dry socket:

• those people who have gingivitis or periodontal disease.
• those who have had lower or mandibular extractions, particularly on posterior (back) teeth such as molars and pre-molars.
• those who have wisdom teeth that are difficult to extract and necessitate bone removal.
• those that are particularly difficult to numb and so need several cartridges of local anesthetic. Some local anesthetics contain epinephrine, which is used in preventing rapid dissipation of the anesthetic by constricting the blood vessels at the site. This perhaps may prevent good clot formation. People who smoke also are predisposed towards dry socket. Again, this may be because of the constricting effect of nicotine and tar products on the blood vessels.

Rinsing the mouth within a few hours of a wisdom tooth extraction may flush the clot out of the socket. Using a straw may have a similar effect. That is why post-operative instructions urge the patient not to smoke, rinse or use a straw for at least a day.

Unfortunately, there is no sure way of guaranteeing that a dry socket won't occur, but there is some evidence that placing a small piece (quarter of a square inch) of gel foam (a clotting agent) covered with tetracycline powder (an antibiotic) in the socket after the extraction can reduce the chance of a dry socket. This will be absorbed over a few days and has not been shown to induce allergies or have any other effect on the patient. Fortunately, dry socket is a relatively easy condition to treat.

Impacted Wisdom Teeth Can Cause Tooth Pain and Dental Problems

Impacted wisdom teeth can be a serious threat to good dental health. Wisdom tooth impaction happens when the developing tooth doesn't come in straight.

An impacted wisdom tooth might never even erupt -- that is, break through the gums. If there is not enough room in the patient's mouth for the new molar, the tooth has no place to go, leading it to push against other teeth or tissues.

Impacted teeth can cause serious tooth pain, face or jaw pain, even headaches. They can lead to orthodontic problems, as other teeth move around to try to make room for them. Crooked teeth, in turn, leave a person more vulnerable to other dental problems.

Teeth impaction is classified either as a soft impaction (when the new tooth is still developing) or a bony impaction (when the developing tooth has begun to harden). Wisdom tooth removal is far easier when it is done earlier rather than later; bony impactions can sometimes require difficult wisdom tooth surgery.

During general dental check-ups, the dentist will monitor the development of a teen's wisdom teeth. If the teeth become impacted, the dentist will suggest wisdom tooth extraction. Patients in the most difficult situations will need to be referred to or to find a wisdom tooth dentist or oral surgeon who can perform their wisdom tooth surgery.

Only a dentist can determine the state of a patient's wisdom teeth. Have the teeth started to develop? Are they heading towards impaction? Are they already impacted? With the help of an x-ray, your wisdom teeth dentist will be able to answer those questions - and suggest a course of treatment.
