Why do my teeth need to be extracted?

There are many reasons as to why teeth need to be removed. Often it is due to significant decay or infection of the tooth. The reasons for removal of your tooth would have been discussed with you by the doctor on the day of your assessment. If you are not happy that you understand why your tooth needs to be removed then please ask.

How does the local anaesthetic work?

On your assessment it has been discussed to extract your tooth under local anaesthetic. This is an injection into the gum surrounding the tooth, similar to that you may have had at your dentist for a filling. The injection takes a couple of minutes to numb the area and means that you will feel no pain while the tooth is removed. The are of the injection will stay numb for a few hours or even longer after the procedure as a result of the local anaesthetic. 

Please eat before the procedure as normal.

What will the procedure involve?

The procedure either involves simple removal of the tooth out of its socket or, sometimes, a cut in the gum over the tooth and removal of some bone surrounding the crown of the tooth.

It may become necessary to cut the tooth into 2 or 3 pieces to remove it. Once the tooth has been removed the gum is put back into place with stitches. In the majority of cases these stitches are dissolvable and can take up to two weeks to dissolve.

How long does it take to remove a tooth?

This is a variable. Some teeth may take only a few minutes to remove. More difficult wisdom teeth can take up to 40 minutes to extract.

Are there any risks?

With dental extractions there is a risk of pain, bleeding, bruising, stiffness in opening the mouth, swelling and infection.

Is there much pain or swelling after the removal of teeth?

It is likely that there will be some discomfort and swelling both on the inside and outside of your mouth after surgery. This is usually worse for the first three days but it may take up to two weeks before all the soreness goes. You may also find that your jaw is stiff and you may need to eat a soft diet for a week or so. It is likely you will need regular painkillers for 3-4 days after the procedure. It may also be necessary for you to have a course of antibiotics after the extraction. There may be some bruising of the skin of your face that can take up to a fortnight to fade away.
