Wisdom teeth

Wisdom teeth are the third and final molars that generally erupt between the ages of 16 and 25. They are the last of your teeth to erupt and can often grow on funny angles causing problems and therefore leading to the need for removal. This is very common as 85% of people actually need their wisdom teeth removing! Though this is not always the case as few people never develop any wisdom teeth at all! Here at Hawthorn East dental we can help you find out exactly how many wisdom teeth you have utilising our onsite OPG machine and digital X-ray technology. We believe it is important to be well informed about your wisdom teeth and are here to help you with your wisdom teeth pain and assist you in preventing future problems.

The Problem with wisdom teeth

Wisdom teeth can cause problems and pain in the mouth. This is often due to a mismatch between the size of your teeth and the size of your jaw. This lack of space can lead to poor oral health and can sometimes jeopardise the strength and functionality of your other teeth! Here are some problems that can come about because of wisdom teeth.


Pericoronitis is infection of the gum surrounding the wisdom tooth and is characterized by a constant dull throbbing pain lasting 1-2 weeks. This pain comes and goes every few months and can be quite unpleasant! It can be sore to chew on that side and difficult to swallow food and drinks. This gum infection can be temporarily treated with antibiotics or local deep cleaning. Although long term, it is best to discuss and plan your wisdom teeth removal options with Dr. David Cao.


Because wisdom teeth are so far back and often on difficult angles it can be extremely hard and sometimes near impossible to keep them clean! This collection of food can cause problems for the teeth next door! As with any area of the mouth that is not cleaned properly decay and bad breath can occur. This decay usually affects both the wisdom tooth and the molar in front known as the Twelve Year Old Molar. The decay often extends deep down near the roots of the tooth and unfortunately cause pain. If severe enough and left untreated this can lead to the need for nerve treatment or the loss of both teeth.


When there is a recurrent infection around the wisdom tooth a cyst may develop. This cyst may cause no symptoms or noticeable pain but can adversely affect and destroy the bone surrounding the affected tooth. In these cases, it is best to remove the wisdom tooth and let the area recover and rebuild as best as it can.


When a wisdom tooth has partially erupted or grown on an awkward angle it can cause short term harm to the surrounding soft tissue. That being ulceration of the gum and cheeks. This problem is eliminated with the removal of the wisdom teeth causing the ulcerations.


The constant pressure and pushing force of wisdom teeth that do not have enough room to erupt naturally and normally can sometimes be enough to cause crowding of your other teeth. Removal of wisdom teeth therefore removes the forces they give and reduce the possibility of crowding.
