Infections can develop anywhere in your mouth – in the gums (periodontal), lips, palate, cheeks, and tongue, or within and below teeth (endodontic). Paying attention to dental health is essential in preventing dental infections. A dental infection within or below a tooth can be caused by tooth decay or a broken tooth that causes the pulp to become infected. The pulp is the part of the tooth that contains blood vessels, connective tissue, and large nerves. When an infection occurs, bacteria can move out of the tooth to the bone or tissue below, forming a dental abscess. A dental infection can lead to sepsis.
Sometimes incorrectly called blood poisoning, sepsis is the body’s life-threatening response to infection. Like strokes or heart attacks, sepsis is a medical emergency that requires rapid diagnosis and treatment.
As with all infections, an infection in your mouth should be treated as quickly as possible to reduce the risk of complications, including sepsis. Saltwater mouth rinses while waiting to see your dentist may ease the pain or discomfort. You might also ask your dentist’s office what you could do before your appointment.
If you have an infection, you will probably get a prescription for an antibiotic. Take this antibiotic as directed until it is finished, even if the pain and swelling seem gone. Feeling better does not necessarily mean that the infection has gone away.
Also, ask your dentist if the infection should be drained. If possible, draining can speed up the reduction of pain and swelling. If your case is more complicated, your dentist may refer you to an endodontist or periodontist.
Preventing dental infections with good dental health
Preventing infections in your mouth will help you reduce your risk of developing sepsis. Usual recommendations are to visit your dentist twice a year for up-to-date x-rays, exams, and dental cleanings.
Good oral hygiene is the first basic step in promoting good dental health and preventing infections. Children should learn these habits early on to help them keep healthy mouths and teeth.
Brush your teeth thoroughly at least twice a day.
Floss your teeth at least once a day.
Don’t over brush – brushing too hard or with too hard a brush can damage your teeth. Ask your dental hygienist for the best way for you to brush your teeth.
Don’t use your teeth to open packaging, break string, etc. Your teeth are strong, but they are for chewing food, not hard objects. These can crack, chip, or break teeth.
Visit your dental office at least twice a year for a thorough cleaning and check-up.
If you have had dental work, watch for any signs of infection and contact your dentist if you experience any of the signs listed above.
Infection after dental work
From cleaning to root canals, dental work may cause bleeding and an opening where bacteria can enter the body. While dentists, hygienists, and dental assistants work to keep everything as clean as possible as they do their work, sometimes infections do develop, just as sometimes they do after surgery on another part of the body.
The American Dental Association recommends that certain people receive prophylactic or preventative antibiotics before dental work is done. These people have certain heart conditions that could make them more prone to developing a condition called infective endocarditis. Some people with artificial joints (like a knee or hip) may need prophylactic antibiotics before dental work. If you have an artificial joint, speak with your doctor before you need dental work to see if this is recommended for you.
Here are some of the most common dental procedures.
Dentists try to avoid pulling teeth (tooth extractions), but sometimes it is the only option. Endodontic (root canal) procedures are preferable to extraction when possible.
Some reasons for having a tooth extracted are:
Too much damage to the pulp (within the tooth) from infection or decay.
Infection that remains, even after treatment with antibiotics.
Loose teeth from gum disease .
Crowded mouth before orthodontics (braces).
Teeth that cannot be restored with a dental crown or restoration.
Another part of good dental health is getting dental repairs as quickly as possible. Tooth fillings can fix a cavity or hole. After cleaning out debris and dirt, the dentist inserts the filling material to protect the tooth.
If you have an infection or have had a root canal, the dentist may put in a temporary filling. A temporary filling protects the pulp from bacteria reaching it and usually helps relieve any pain that you may be feeling. Permanent fillings must replace temporary ones.
Your dentist may suggest a root canal done for badly decayed or infected teeth before the more drastic step of extracting (pulling) the tooth.
The dentist or endodontist removes the nerve and pulp from the inside of the tooth. A sterile inert (chemically inactive) material replaces the pulp.
If you suspect sepsis, call 9-1-1 or go to a hospital and tell your medical professional, “I AM CONCERNED ABOUT SEPSIS.”

Shawn started with dizziness, nausea and fatigue. His blood pressure soared to stroke levels, and his heart rate was nearly 100 bpm.

The ER doctor recommended that he have that taken out as soon as possible, and they sent him home with medications to address ... Read Full Story
It all began on a Sunday. I had gone to the ortho dentist two days prior for dental work, to include the removal of an abscessed root canal.

About a year ago, I had gone to the dentist and had a root canal done, for which, my dentist gave me a prescription for an antibiotic. (Sepsis and Dental Health) I don’t think I was done with the prescription, but one night, I just didn’t feel right. For no reason apparent to me, I had the chills so bad my teeth were chattering. I couldn’t hold still long enough to stay in bed and sleep so I decided to take a hot bath. I got in the water but it wasn’t a comfort or help with the chatters. I ... Read Full Story
