We all use the term
wisdom teeth when referring to teeth that technically are known as
third
molars. These teeth can be seen on panoramic x-rays
as early as nine or ten years of age. Human beings usually have 32
teeth. The last four teeth in the jaw are the third molars and this
posterior positioning in the jaw often causes multiple problems for
patients. These teeth are often impacted (submerged in the jaw
under gum and in the bone).
Third molar roots
start to develop in most individuals when they are in the 15 to 18
year old age range. At this time the teeth begin to migrate and the
root development starts to propel the teeth upward towards the
mouth. When this occurs these teeth can cause pain due to the
proximity of the major sensory nerve in the lower jaw to the roots
of the lower third molars. As third molars continue to develop they
can possibly cause some shifting to neighboring teeth.
Later in
development third molars may start to enter the mouth and when this
occurs bacteria can become trapped under the gum and in between the
adjacent second molar teeth. This can lead to recurrent nagging
infections and potentially deep decay on the root of the second
molar teeth as well as worsening infection of the third molars.
 A
panoramic x-ray is necessary to completely evaluate the position of
the third molars and adjacent teeth as well as other jaw structures
(nerve in the lower jaw, sinus cavity in the upper jaw). Many
general dentists routinely take panoramic x-rays in new patient
exams which can be used for your consultation with Dr. Faerber. It
is preferable to have a panoramic x-ray no older than one year prior
to surgery due to potential changes in root development.
The surgery to
remove third molars is usually performed under I.V. anesthesia on an
outpatient basis. Adequate recovery time should be allowed which
ranges for many patients. Some patients with simpler extractions
can return to work the next day. Removal of four impacted third
molars usually requires a day or two to recover. Swelling usually
reaches its maximum by the third day and then starts to diminish the
next week. Ice bags, gauze and prescriptions for pain medication as
well as an antibacterial mouth rinse are provided with all
surgeries. Many patients can control their pain after surgery with
400 to 800 mg of over the counter ibuprofen without needing to take
the prescription pain medication. |
