Submandibular space infection; Sublingual space infection
Ludwig angina is a type of bacterial infection that occurs in the floor of the mouth, under the tongue. It often develops after an infection of the roots of the teeth (such as tooth abscess) or a mouth injury.
This condition is uncommon in children.
Ludwig angina is an infection of the floor of the mouth under the tongue. It is due to bacteria.
Your health care provider will do an exam of your neck and head to look for redness and swelling of the upper neck, under the chin.
The swelling may reach to the floor of the mouth. Your tongue may be swollen or pushed up to top of your mouth.
You may need a CT scan.
A sample of the fluid from the tissue may be sent to the lab to test for bacteria.
Ludwig's angina can be life threatening. It can be cured with getting treatment to keep the airways open and taking antibiotic medicine.
Complications may include:
Visit the dentist for regular checkups.
Treat symptoms of mouth or tooth infection right away.
The infected area swells quickly. This may block the airway or prevent you from swallowing saliva.
Other symptoms that may occur with this disease:
If the swelling blocks the airway, you need to get emergency medical help right away. A breathing tube may needed to be placed through your mouth or nose and into the lungs to restore breathing. You may need to have surgery called a tracheostomy that creates an opening through the neck into the windpipe.
Antibiotics are given to fight the infection. They are most often given through a vein until symptoms go away. Antibiotics taken by mouth may be continued until tests show that the bacteria have gone away.
Dental treatment may be needed for tooth infections that cause Ludwig's angina.
Surgery may be needed to drain fluids that are causing the swelling.
Breathing difficulty is an emergency situation. Go to the emergency room or call your local emergency number (such as 911) right away.
Call your provider if you have symptoms of this condition, or if symptoms do not get better after treatment.
