Wisdom teeth
A Wisdom tooth is often a problem because there isn't enough space for
it in the dental arch. These teeth are technically
called third molars. First molars erupt in the mouth at about the age of
six or seven. At around age twelve or thirteen, the second molars erupt.
Third molars, if they are going to come in at all, will begin to show up
sometime around age nineteen and may take a couple of years or more, if
they come in, to fully come in.
We get along just fine with two sets of molars. Why we are
given three when we only need two is a great mystery. In
older cultures where dental care is primitive, the first molars, which are
very prone to tooth decay, may rot away and be gone by the time the third molars
come in. This will leave the person with only two sets of molars, which is
all the modern human jaw ordinarily has space for.
When they don't erupt in the mouth, often the best policy is to
have wisdom teeth removal.

and after the surgery.
Some dentists have taken the position that until you get a
tooth abscess, they shouldn't be removed. We recommend that once it's
determined that there isn't enough space for them to fully erupt into the
jaw, they should be removed. There is solid reasoning
behind this recommendation, and here it is:
When a wisdom tooth is not yet fully developed, during the late teens up
until about age twenty-one or twenty-two, the
tooth extraction procedure is generally
very straightforward. Not only are the teeth much easier to
remove then, but the chances of complications are truly minimal. From age twenty to
twenty-five, the risk of complications from the removal of wisdom teeth
doubles. From age twenty-five to thirty, it probably doubles again,
and it continues to increase beyond that. The roots of the wisdom
teeth become fully formed, and the bone becomes harder and more dense.
Once a patient reaches the age forty, the risk of complications becomes
very great.
For patients over forty, we would recommend a conservative approach. At
that age, the risk of complications is great. Besides that, if you have
not had a wisdom tooth infection until then, the chances that they will
cause a problem in the future is lower. But for patients who are age
twenty or younger, it seems to make the most sense to take them out while
their extraction is easy. Permanent nerve damage, which
can cause a patient to lose all sensation in his or her lip, is the most
serious common complication of this surgery, and is the nightmare that no
oral surgeon wants to deal with. It is very difficult to
damage the lip nerve if the teeth are extracted before the roots are
formed, but it can be easy to damage it afterward.
We have seen it recommended on some web sites to get an opinion on your
wisdom teeth from someone who doesn't make his or her living taking them
out. For those inclined to be suspicious of professional people, this advice
sounds wise. The idea to leave them alone if they're not bothering you has a
seductive ring to it. Having taken out many wisdom teeth myself and being now
in a situation where I receive no financial gain from my advice, I still advise
people to get them out young. From personal experience, I am certain that the
reason oral surgeons are so emphatic about this is that they have removed some
of these on patients that were 30, 35, 45, and older, and they know how
tough they are to get out at that age and are only too painfully aware, from
phone calls received from patients, of the healing complications that escalate
with increasing age. I know what some of those phone calls and after-hours
emergencies can be like. I personally took out wisdom teeth of every configuration,
but I drew the line on patients who were 40 and above. I knew these people would
have complications and I didn't want to be the person they identified as the source
of all that misery I knew they were going to experience. So I referred those patients
to other practitioners.
So, don't suffer needlessly—get your wisdom teeth removed while you are young.
