Common Oral Infections You Need To Know About

Considering the amount of work our mouths have to do, their vulnerability to certain infections and conditions becomes more understandable. Yet, an oral cavity passes the endurance test in most cases. In this article, we will discuss some common complications or infections occurring inside our oral cavities.

Dental caries or cavities

Dental caries, also known as cavities, are holes in teeth occurring due to tooth decay. A cavity is one of the most common oral infections. According to a study published by the National Institute of Dental and Craniofacial Research, a cavity is the most common reason for the loss of primary teeth in children. Holes in teeth appear as a result of the tooth decay caused by the bacteria Streptococcus mutans. This bacteria species feeds on sugar. Foods that provide sustenance to this species are rice, chips, and anything that can break down into glucose.


Gingivitis is an early infection in the gums, caused by inflammation. This initial problem can transform into a much severer periodontal condition. Gingivitis occurs when bacteria settle in the gum line. Those bacteria then produce toxins, which can cause inflammation in the gum tissues. This condition can cause your gums to bleed particularly when you brush your teeth. Removing those bacteria by upping your dental hygiene game can help prevent and even reverse gingivitis. You can also ask your dentist to provide gingivitis treatment.

Periodontal disease

Allowing gingivitis to grow can bring up periodontal disease, which is a severer form of gum inflammation. This disease is also known as periodontitis. It develops when oral infections grow below the gum line and form pockets between tooth roots and gum tissues. Gums start to recede, and further inflammation causes bone loss, resulting in the jawbone and gum tissues losing hold of teeth. According to research, periodontal disease is the leading cause of tooth loss in 47.2% of adults of 30 and above.


Thrush occurs as a result of an overgrowth of naturally occurring Candida albicans. This condition develops and prevails as a result of chemotherapy, antibiotics, and radiation. Its symptoms mainly include the formation of curd-like, white plaque on the tongue, inner cheeks, back of the throat, and roof of the mouth. People with HIV are at a higher risk of having oral thrush.

Hand, Foot, and Mouth Disease

This viral infection of the mouth and other parts of the body is more prevalent in toddlers and children, as stated by the University of Chicago. It usually develops due to a virus called Coxsackie A16. While this condition sounds scary, it goes away within two to three days.


This condition is quite similar to Hand, Foot, and Mouth Disease. Its symptoms include sore throat, fever, and difficulty swallowing. This condition also results in the formation of tiny blisters at the back of the mouth.

Canker sores

Also known as aphthous ulcers, canker sores can be significantly annoying. However, they go away after 14 days without any medical intervention. While the actual reason for these sores is unknown, possible triggers include hormones, stress, food hypersensitivity, and immune system problems.
