Periodontal Pocket

A periodontal pocket is a pocket between just below the gumline, between the gum tissue and the tooth. In a healthy mouth, there is an area of possible space, called the gingival sulcus, between the margin of the gum tissue and the tooth. When this area enlarges due to the detachment of the periodontal ligament from the surface of the tooth, the pocket that is formed is indicative of the gum disease periodontitis, and this enlarged pocket is known as a periodontal pocket. Inflammation or irritation may also temporarily increase the size of pockets between the gums and the teeth; true periodontal pockets must measure a probing depth of 4 mm or more. This depth indicates that the fibers that once attached the gum tissue to the tooth have been destroyed, and, as periodontitis progresses, periodontal pockets deepen. The deeper they are, the more bacteria they can contain, resulting in the need for consistent management in order to reduce the damaging effects of periodontitis. Periodontal pockets may also become infected, leading to abscess. The probing depth of periodontal pockets is carefully monitored and recorded as part of periodontal treatment.

Periodontal pockets develop due to a number of factors, but the ultimate cause is the accumulation of dental plaque. When bacteria found in dental plaque invade the tissues of the periodontium, which is the set of specialized tissue that surrounds and supports the teeth, the body’s immune system responds with inflammation. When plaque is allowed to remain on the teeth without being sufficiently and thoroughly managed, it eventually hardens, calcifying and turning into dental calculus. Dental calculus can’t be removed with home dental tools and requires professional cleaning. If dental calculus remains on the teeth, it creates a roughened surface that provides an ideal breeding ground for the buildup of additional plaque, which accumulates inside the periodontal pockets as well as above the gum line, leading to additional inflammation. This continuous cycle of invasion and inflammation gradually degrades the ligament and fibers that hold the tooth in place and also degrades the bone that supports the tooth, eventually resulting in tooth loss and other unsavory symptoms.

While periodontitis can be prevented, once periodontal pockets have formed, they cannot be restored to a healthy depth without significant intervention, usually surgical in nature. Therefore, preventing gum disease through a meticulous oral health routine is crucial to maintaining the overall health of the periodontium and the oral cavity. Plaque levels can be effectively managed with twice-daily brushing with fluoride toothpaste, in conjunction with daily flossing or other interdental cleaning and periodic professional dental checkups and cleanings. In some cases, certain risk factors can contribute adversely to a person’s predisposition to gum disease. These risk factors include some systemic conditions and diseases; habits, such as smoking and certain dietary preferences; and the layout and placement of dental restorations and orthodontic appliances, some of which may be more prone to trapping bacteria and debris in hard-to-reach places. Even with these risk factors, good oral hygiene combined with regular professional dental cleanings effectively removes significant amounts of bacterial plaque and can prevent the formation of periodontal pockets, or slow or halt the progression of pockets that have already formed.
