The gingiva, or gums, are the pink-coloured keratinized mucosa that surrounds and protects the teeth. They are part of the soft tissue lining of the mouth and are tightly bound to the underlying bone. The gingiva is perfused by multiple small arteries that originate from branches of the carotid artery. While the gingiva does not contain muscle, it is innervated by nerves derived from the mandibular and maxillary divisions of the trigeminal nerve. These nerves provide sensory and motor innervation to the gums and surrounding structures. The health of the gingiva is important for maintaining oral health and preventing periodontal disease, which can lead to tooth and bone loss.

What You'll Learn
Gingiva is a tissue that surrounds the teeth
Gingiva, also known as gums, is a tissue that surrounds the teeth and provides a seal around them. It is made up of mucosal tissue that lies over the mandible and maxilla inside the mouth. The gingiva is part of the periodontium, which includes the investing and supporting structures of the teeth. It is perfused by multiple small arteries that originate from branches of the carotid artery.
The marginal gingiva is a strip of soft tissue that surrounds the neck or base of the teeth. It is not bound to the teeth and can be moved away from them by a dentist using a tiny ruler or probe. The attached gingiva, on the other hand, is a second layer of soft tissue that is tightly bound to the underlying periosteum of the alveolar bone. It is firm, resilient, and cannot be moved by a dentist. The width of the attached gum varies according to its location in the mouth, with the greatest width usually found in the incisor region.
The interdental gingiva, or interdental papilla, is the tissue between the teeth. It occupies the gingival embrasure, which is the interproximal space beneath the area of tooth contact. The marginal gum, which includes the marginal and attached gingiva, surrounds the teeth in a collar-like fashion. The marginal gingiva is stabilized by the gingival fibres that have no bony support, while the attached gums are resistant to the forces of chewing.
Healthy gingiva is usually coral pink in light-skinned individuals and may be naturally darker in people with higher melanin pigmentation. Good oral hygiene practices, such as brushing teeth twice a day, flossing daily, and regular dental visits, are essential to maintaining healthy gingiva and preventing periodontal disease, which can lead to tooth and bone loss.

Gum health and disease
The gums, or gingiva, are the pink-coloured keratinized mucosa that surrounds and protects the teeth. They are part of the soft tissue lining of the mouth and are tightly bound to the underlying bone, which helps resist the friction of food passing over them. Healthy gums are usually coral pink in light-skinned people and may be naturally darker with melanin pigmentation.
Research has found that bacteria associated with periodontal disease can be aspirated into the lungs and contribute to respiratory diseases such as pneumonia. Additionally, gum disease bacteria may be able to travel to the brain and contribute to the development of Alzheimer's disease. The inflammation caused by gum disease has also been linked to an increased risk of heart disease and high blood pressure.
There are several ways to improve gum health and prevent gum disease. It is recommended to limit or eliminate alcohol use, as chronic alcohol use is associated with gum disease and oral cancers. Oral health relies on a healthy balance of bacteria in the mouth, so antibacterial mouthwash should be avoided unless recommended by a dentist. Brushing teeth at least twice a day and flossing at least twice a day are also important for gum health. Regular dental check-ups and professional cleanings every six months are crucial, and people with gum disease may need more frequent visits.

Gum injuries
The gums, or gingiva, are the mucosal tissue that lines the mandible and maxilla inside the mouth. They are a type of soft tissue and are susceptible to injury. Gum injuries can occur due to accidental bites, falls, sports injuries, scalding liquids, or foreign bodies becoming lodged between the teeth and gums.
Types of Gum Injuries
Cuts
Cuts on the gums can occur due to sharp or hard objects in the mouth, toothbrush bristles, or falls and other types of injuries. These cuts can bleed profusely due to the large blood supply to the gums, and they can become infected. Most gum cuts are mild and can be treated at home with salt water rinses and cold compresses. However, it is important to know when to seek medical attention. If symptoms such as excessive pain, bleeding, or pus are present, it is recommended to see a healthcare professional.
Abscesses
Abscesses are another type of gum injury that can be quite painful due to the buildup of pressure inside them. Symptoms include a sudden throbbing toothache, tenderness, and swelling of the gums or face, and sometimes fever. Abscesses can persist for months if left untreated and can lead to serious health problems, including infections that spread to other parts of the body. Therefore, it is crucial to seek dental treatment for abscesses as soon as possible.
Treatment for Gum Injuries
Home Care
For minor gum injuries, such as small cuts, rinsing the mouth with a dilute salt water solution can help prevent infection and control bleeding. Applying a cold compress to the outside of the mouth can help reduce pain and swelling.
Medical Treatment
In more severe cases, such as deep cuts or persistent bleeding, it is important to see a dentist or healthcare professional within 6 hours of the injury. Treatment may involve determining the extent of the damage, performing restorative procedures, suturing the wound, and administering antibiotics or tetanus shots if necessary.
Prevention of Gum Injuries
To prevent gum injuries, it is advisable to avoid placing sharp or hard objects in the mouth and to be cautious when consuming sharp or hard foods. For individuals who participate in contact sports, wearing a mouth guard can help protect against oral injuries, including gum injuries.

Gum pigmentation
The gums or gingiva are a masticatory mucosa lining the alveolar bone that surrounds the cervical portion of the teeth. Healthy gums are usually coral pink in light-skinned people and may be naturally darker with melanin pigmentation in people with darker skin.
There are several treatments for gum pigmentation, including gum depigmentation, which uses a laser to safely and successfully treat dark gum splotches. The procedure typically takes less than an hour, and the results last for decades. Another treatment option is gum bleaching, but this method does not remove the melanocytes that cause the discoloration.

Gum recession
Gingiva, or gums, are the pink-coloured keratinized mucosa that surrounds and protects the teeth. Gum recession, or gingival recession, is a process in which the margin of the gum tissue that surrounds the teeth wears away or pulls back, exposing more of the tooth or its root. This can leave individuals at higher risk of tooth sensitivity, cavities, and tooth loss. Gum recession is a common dental problem, often caused by gum disease, and can be treated through deep cleaning, medication, or surgery.
Causes
There are several factors that can cause gum recession, some of which are controllable, while others are not. One of the main causes is gum disease, which can be influenced by genetics, with studies showing that about 30% of the population may be predisposed to it. Poor oral health, such as inadequate brushing, flossing, and rinsing, can lead to plaque buildup, which in turn results in gum disease and gum recession. Aggressive or incorrect tooth brushing and flossing can also contribute to the problem.
Hormonal changes during puberty, pregnancy, or menopause can make gums more sensitive and susceptible to recession. Tobacco use is another direct cause of gum recession, as it leads to sticky plaque buildup on teeth. Teeth grinding or clenching, also known as bruxism, can put excessive force on the teeth and gums, causing them to recede. This usually occurs during sleep and can be easily addressed with a mouth guard.
Other factors include crooked or misaligned teeth, which can place uneven pressure on the gums and underlying bone. Body piercings in the lip or tongue can irritate and wear away gum tissue over time. Additionally, certain medications can cause dry mouth, reducing the amount of saliva and making the mouth more vulnerable to bacterial infections and injuries.

Frequently asked questions
Gingiva, or gums, is the pink-coloured keratinized mucosa that surrounds and protects the teeth. It is perfused by multiple small arteries that originate from branches coming off of the carotid artery.
The gingiva is not made of muscle, but of soft mucosal tissue. However, it is supplied with nerves and arteries that originate from the maxillary and mandibular divisions of the trigeminal nerve.
The gingiva surrounds the teeth and provides a seal around them, helping to keep them in place. It also acts as a barrier to protect the deeper tissues from friction and periodontal insults.
