The gingiva is the soft tissue that surrounds and supports the teeth in the oral cavity. It is made up of two parts: the free gingiva and the attached gingiva. The free gingiva is the part that is visible in the mouth and surrounds the tooth, while the attached gingiva is attached to the underlying bone and helps to anchor the tooth in place. The interdental gingiva is the part of the gingiva that is located between the teeth [1-3]. It is also known as the interdental papilla .The interdental gingiva plays an important role in maintaining the health of the teeth and gums. In this article, we will discuss the anatomy, function, and importance of interdental gingiva. The interdental gingiva is a triangular-shaped piece of tissue that is located between two adjacent teeth. It is composed of two interproximal papillae and an interdental col or space. The papillae are the pointed areas of the gum tissue that fill the space between the teeth, while the col is the space between the papillae. The papillae are also divided into two types: the facial and the lingual papillae. The facial papillae are the ones that face the cheek or lips, while the lingual papillae are the ones that face the tongue [4,5]. The interdental papillae are made up of connective tissue and covered by a thin layer of epithelium. They are highly vascularized and innervated, which means they receive a good blood supply and are sensitive to touch and pressure. The papillae also contain a network of collagen fibres that provide support to the surrounding teeth and bone. The primary function of the interdental gingiva is to protect the underlying bone and teeth from damage caused by bacteria and other harmful substances [6-9]. The interdental papillae act as a barrier to prevent food particles and bacteria from entering the space between the teeth. The papillae also help to maintain the proper spacing between the teeth, which is important for proper occlusion and bite. The interdental papillae also play an important role in speech and phonetics. They help to form the sounds of certain letters and words, such as the “s” sound in the word “miss”. Without the proper formation of the interdental papillae, speech and phonetics can be affected. Maintaining healthy interdental gingiva is important for overall oral health. When the interdental papillae are healthy, they help to prevent the build-up of plaque and bacteria between the teeth. This can help to prevent cavities, gum disease, and other oral health problems.

However, when the interdental papillae become inflamed or damaged, they can lead to a number of oral health issues. One common problem is interdental gingivitis, which is inflammation of the interdental papillae. This can cause redness, swelling, and bleeding between the teeth. If left untreated, interdental gingivitis can progress to periodontitis, which is a more serious form of gum disease that can lead to tooth loss. Another issue that can arise from unhealthy interdental gingiva is food impaction. This occurs when food particles become trapped between the teeth and the papillae, causing discomfort and even pain [10]. Food impaction can also lead to the development of cavities and gum disease. Maintaining healthy interdental gingiva requires proper oral hygiene practices, such as regular brushing and flossing. It is important to clean the spaces between the teeth and the papilla.
