Mouth infections, also referred to as oral infections, are a gaggle of infections that occur round the mouth. They include dental infection, dental abscess, and Ludwig's angina. Mouth infections typically originate from cavity at the basis of molars and premolars that spread to adjacent structures.. Since bacteria that normally reside within the mouth cause mouth infections, proper dental hygiene can prevent most cases of infection. As such, mouth infections are more common in populations with poor access to care (homeless, uninsured, etc.) or populations with health-related behaviors that damage one's teeth and oral mucosa (tobacco, methamphetamine, etc.)

Dental pain and swelling are the 2 hallmark symptoms of a mouth infection. Fever is usually present, but not as frequently as tooth pain or persistent swelling. Other symptoms that sometimes accompany an infection like increased pulse , low energy, chills, and sweating can also be present. If infection spreads to the space between the muscles of mastication, then trismus, the lack to completely open one's mouth, also will be present.

Mouth infections are most ordinarily caused by an overgrowth of bacteria that normally populate the mouth .during a healthy adult, billions of bacteria, viruses, and fungi reside within the mouth and represent quite 500 different species. they're collectively referred to as the oral microbiome. However, certain situations, sort of a decaying root or a penetrating puncture wound from a fish bone, can generate an environment that disrupts the traditional oral microbiome and promote the expansion of pathogenic bacteria. Although sore throats (pharyngitis) are caused by viruses and oral yeast infections (candidiasis) are caused by fungi, most mouth infections that cause swelling and abscesses are caused by bacteria.

Mouth infections are usually diagnosed on history and physical exam within the dental office or at a clinic visit with an otolaryngologist. Swelling within the mouth or cheeks, along side a history of progressively worsening tooth pain and fevers, is typically enough evidence to support the diagnosis of a mouth infection. counting on the severity of the infection, further tests may include x-rays and CT scans of the mouth to raised characterize the situation and extent of the infection.If the infection is drained with a needle or scalpel, then a swab of the infection is collected to spot the microbes present within the abscess and to work out their respective susceptibilities to antibiotics.

Securing a patient's airway is that the most vital a part of initial treatment because loss of airway is emergently life-threatening. Inflammation and enormous abscesses, particularly those within the ground of the mouth, may block airflow into the lungs. To pre-emptively protect a patient's airway, placing flexible plastic tubing through the cavity and into the trachea, called endonasal intubation, is usually the primary option. It are often performed with or without direct visualization with laryngoscopy, alittle camera with a live video feed to make sure the tubing is placed within the proper location. If attempts to intubate through the cavity are unsuccessful or if the airway must be re-established quickly, then an incision are often made through the front of the neck to realize access into the trachea, also referred to as a tracheotomy.
