More than 800 species of bacteria colonize oral mucus, 1,300 species are found in the gingival crevice, and nearly 1,000 species comprise dental plaque. The mouth is a rich environment for hundreds of species of bacteria since saliva is mostly water and plenty of nutrients pass through the mouth each day.
Mouth infections are most commonly caused by an overgrowth of bacteria that normally populate the oral cavity. [1] In a healthy adult, billions of bacteria, viruses, and fungi reside within the oral cavity and represent more than 500 different species. They are collectively known as the oral microbiome.
Here's how to read an audiogram and a doctor's explanation of the most common results including sloping hearing loss, notched hearing loss, cookie-bite hearing loss and reverse-sloping hearing loss.

Periodontal refers to the area the infection affects, which include the teeth, gums, and tissues surrounding the teeth. Bacteria cause inflammation of the gums which become red, swollen and can bleed easily. The bacteria along with mucus form a sticky colorless substance called plaque which harbours the bacteria.
The bacteria is usually only found in the mouth, far from the colon. In the mouth, it’s one of the most common types of disease-causing bacteria , linked to gum disease and plaque buildup.
The BSA-recommended procedures provide a "best practice" test protocol for professionals to follow, increasing validity and allowing standardisation of results across Britain.
