Infections are very common following extractions. Depending on how bad the tooth was that the dentist removed, he may prescribe you some antibiotics to take that will greatly reduce your risk of getting an infection. In some cases though, even antibiotics can’t prevent an infection.
If you go to the dentist before the extraction experienced swelling of the face, swollen gums, pain in your teeth under light pressure, or bleeding around the extraction site, then you may already have an infection. If you indeed have an infection before you get the tooth treated, the dentist will prescribe you antibiotics to use following treatment. If you have a really bad abscess, you’ll need to use antibiotics to treat the infection before the dentist will remove the tooth.
In some cases, people develop an infection after the extraction, even though they may not have been infected beforehand. Following an extraction, bacteria will be more alive in the mouth than ever before. With the extraction site being exposed, the bacteria will be able to get into the site. Not being able to sterilize your mouth means that you are unable to kills the germs responsible for bacteria.
After extractions, the first sign of infection is renewed bleeding. This normally occurs around 48 hours after the extraction. Some dentists prefer to give patients antibiotics before they will do any type of extraction. Although you may not have an abscess, most dentists prefer to get rid of the infection before they start doing their work. Sometimes, dentists will choose to use an IV sedation or laughing gas, in the event that local numbing doesn’t help. An IV sedation will normally put you to sleep or knock you out, so that the dentist can remove the tooth that is causing you so much trouble.
Even though infections can cause a lot of pain and need to be dealt with immediately, you may not have to take antibiotics once the dentist has extracted the tooth. Rinsing your mouth out with salt water for the first few days will keep the extraction site clean. As long as you take care of the extraction site and do what your dentist tells you, you shouldn’t have any further problems with the extraction site or the infection.
