Re: pulling a bad tooth
Why do you think there is an infection there? Were you told the tooth and/or gum tissue is infected? Is there a drainage area present? Do you get a bad taste/foul odor in your mouth? Does the tooth feel 'squishy' in the socket?
I'm just asking because sometimes decay in the teeth can cause a severe toothache, but not necessarily an infection.
If it's a small infection and one that your body can fight, the dentist will still pull the tooth. The infection will begin to clear once the tooth has been removed and there is little chance that the infection will spread to your blood stream and cause problems.
If the infection has become worse and too large for your body to fight on it's own, the dentist will prescribe antibiotics for you to take for 7-10 days. These large infections are the ones to be concerned about entering your blood stream and causing problems. This is why antibiotics are prescribed and the extraction is rescheduled until the infection is either gone or under control.
Your health is a factor as well. If you are diabetic, have problems with your immune system, have gone through radiation or chemo, and things like that, can affect how well your body fights infection. Depending on your current health, the doctor may prescribe antibiotics for a small infection and might opt to reschedule the extraction.
