Wisdom Teeth Complications

Your wisdom teeth generally make an appearance sometime in your late teens and early twenties. For some people this causes no issues at all, but for others the wisdom teeth may not be straight, or they can get blocked by other teeth so they can’t fully come through. If this happens, you may be required to undergo a procedure to have your wisdom teeth removed.


The first indication of a problem with your wisdom teeth is often pain in the form of a dull ache or a sharper stabbing pain as the teeth press on nerves, surrounding teeth or begin to erupt through the surface of the gums. A partially erupted wisdom tooth is a common cause of pain and discomfort, and if the teeth are not coming in completely straight, they can start to come through your gum but then get stuck.



If you have impacted wisdom teeth your dentist may advise you to have them removed. This will remove the source of your discomfort and prevent any further complications. While it’s normal to be concerned about having a procedure, if left, impacted wisdom teeth can cause a number of issues.

Finding a good dentist who specialises in wisdom teeth removal in Sydney will go a long way towards easing any concerns. Here are a few of the complications that can be caused by impacted wisdom teeth.


Gum disease

When the wisdom teeth are only partially erupted, it can be difficult to clean the surrounding area. This can lead to an increase in the likelihood of gum disease. Gum disease can cause pain, inflammation, tooth loss and other issues.


Tooth decay

The wisdom teeth themselves can be at higher risk of decay when they are only partially impacted. Because they are harder to clean, food and bacteria can get stuck between the gum and tooth, causing a higher level of tooth decay and more likelihood of cavities.


Damage to surrounding teeth

When impacted wisdom teeth rub against other teeth, they can cause damage, increasing the risk of infection. Wisdom teeth can also cause crowding in the mouth as they push other teeth around and this can lead to further issues and a need for straightening treatment.



Cysts are a rare but potentially serious complication that can arise from impacted wisdom teeth. Cysts develop when the sac the wisdom tooth develops in fills with fluid.

This can cause damage to the jawbone, teeth and nerves. In very rare cases a benign tumour can develop which may require removal of tissue and bone.

If you have any pain in your teeth and suspect that wisdom teeth might be the problem, it’s important to get to a dentist as soon as possible. An x-ray will determine whether wisdom teeth are the cause of the problem and if so, your dentist can discuss the next steps with you.
