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. Extractions can also be done under sedation.
Extractions
Having a tooth out is the same as having an operation and, because of this, you must look after the area to speed healing and to reduce the risk of infection. Here are some pointers:
For the first 24 hours, try to avoid eating hot food, don't smoke, don't drink any alcohol and try not to disturb any blood clot which might have formed.
Don't rinse your mouth for 24 hours after extraction. After that, rinse gently with warm salty water - half a teaspoon of salt in a glass of water is enough.
