Wisdom teeth are the last teeth to appear, right at the back of the mouth, usually when you’re in your late teens. Most people have four wisdom teeth – two at the top, two at the bottom – but some people have fewer than this, or even none at all.
Because they’re the last teeth to come through, there may not be room in your mouth for them. As a result, they can push the existing teeth forward, causing overcrowding in the mouth and possibly some discomfort, therefore the best thing to do is to visit your dentist.
The dentist will probably take an x-ray of your mouth to see how – or if – your wisdom teeth are coming through. From this, they will be able to make a judgement on whether or not to take them out, and how easy or difficult it might be.
Often – especially if the teeth are already partway through – your dentist will be able to remove the wisdom at their practice. However, if they think it might be difficult, they will probably refer you to a dental hospital where you can have them removed under general anaesthetic.
