When to Remove
Wisdom Teeth
|
|
Wisdom teeth
cause more problems than any other tooth in the mouth. They will either
partially break the gum tissue and grow in crooked or remain underneath
the gum. In nine out of ten people, at least one tooth remains
underneath the gum - referred to as an impacted
tooth, causing symptoms of future problems of varying
degrees. "Even if you have no symptoms now, headaches, earaches,
pain in the face, neck, throat and upper and lower teeth can occur if
impacted wisdom teeth are not removed." |
|
 |
Wisdom teeth
generally cause problems when they erupt partially through
the gum. The most common reasons for removing them are: |
|
Decay
Saliva, bacteria and food particles can collect around an impacted wisdom
tooth, causing it, or the next tooth to decay. It is very difficult to remove
such decay. Pain and infection will usually follow.
Gum Infection
When a wisdom tooth is partially erupted, food and bacteria collect under
the gum causing a local infection. This may result in bad breath, pain, swelling
and trismus (inability to open the mouth fully). The infection can spread to
involve the cheek and neck. Once the initial episode occurs, each subsequent
attack becomes more frequent and more severe.
Pressure Pain
Pain may also come from the pressure of the erupting wisdom tooth against
other teeth. In some cases this pressure may cause the erosion of these teeth.
Orthodontic
Reasons
Many younger patients have had prolonged orthodontic treatment to
straighten teeth. Wisdom teeth may cause movement of teeth (particularly the
front teeth) when they try to erupt and this will compromise the orthodontic
result.
Prosthetic
Reasons
Patients who are to have dentures constructed should have any wisdom
tooth removed. If a wisdom tooth erupts beneath a denture it will cause severe
irritation and if removed, the patient will need to have a new denture
constructed as the shape of the gum will have changed.
Cyst Formation
A cyst (fluid filled sac) can develop from the soft tissue around an
impacted wisdom tooth. Cysts cause bone destruction, jaw expansion and
displacement or damage to nearby teeth. The removal of the tooth and cyst is
necessary to prevent further bone loss. Rarely, tumors may develop within these
cysts or the jaw may fracture spontaneously if the cyst grows very large.
Why Should an
Impacted Wisdom Tooth be Removed if it Hasn't Caused any Trouble?
Impacted wisdom teeth are almost certain to cause problems if left in
place. This is particularly true of the lower wisdom teeth. Such problems may
occur suddenly, and often at the most inconvenient times.
When is the Best
Time to Have my Wisdom Teeth Removed?
|
It is now recommended by specialists that
impacted wisdom teeth be removed between the ages of 14 and 22 years
whether they are causing problems or not. Surgery is technically easier
and patients recover much more quickly when they are younger. What is a
relatively minor operation at 20 can become quite difficult in patients
over 40. Also the risk of complications increases with age, and the
healing process is slower.

Travel to
Inaccessible Places
If you are going to an area where specialist dental services are not
available and your wisdom teeth are impacted, it may be advisable to have them
removed beforehand.
Should a Wisdom
Tooth be Removed When an Acute Infection (Pericoronitis) is Present?
Generally, no. Surgery in the presence of infection can cause infection
to spread and become more serious. Firstly, the infection must be controlled by
local oral hygiene, antibiotics and sometimes the extraction of the opposing
wisdom tooth.
| The
Pro's and Con's of Wisdom Tooth Removal |
"We should remove them
because..."
 |
Wisdom teeth may be hard to access with your
toothbrush or floss. Over time, the accumulation of bacteria, sugars
and acids may cause a cavity to form in the tooth. If it is not
restored with a filling, the cavity may spread and destroy more
tooth structure causing severe consequences to the tooth and
surrounding supportive structures.
|
 |
Due to the difficulty of keeping these teeth clean
with your daily home care (brushing and flossing), bacteria and food
debris remaining on the wisdom teeth may present a foul
smell-causing bad breath.
|
 |
A wisdom tooth that is still under the gums in a
horizontal position (rather than a vertical position) may exert
pressure to the surrounding teeth, causing crowding and crooked
teeth. This also may occur if there is not enough space in the mouth
for the wisdom tooth. This may warrant braces to repair the damage.
|
 |
A wisdom tooth that is still under the gums may
become irritated. The gum tissue that lays over the tooth may harbor
food debris and bacteria that gets trapped under the gum, resulting
in an infection in the gums.
|
"Let them stay
because..."
 |
Depending on the size shape and position of the
tooth, removal can vary from a simple extraction to a more complex
extraction. With a simple extraction, there is usually little
swelling, bruising and/or bleeding. More complex extraction will
require special treatment which may result in more bruising,
swelling and bleeding. However, your dental professional will
provide you with post treatment instructions to minimize these side
effects.
|
 |
Following an extraction, a condition called dry
socket
may occur (see below). If the blood clot
that formed in the extraction area becomes dislodged, it exposes the
underlying bone. This condition is very painful, but resolves after
a few days. It is preventable by following the post treatment
instructions provided by your dental professional.
|
 |
The longer you wait and the older you get, there is
the potential for more problems to occur. This is because as you get
older, the bone surrounding the tooth becomes more dense, making the
tooth more difficult to remove. The healing process may also be
slower.
