Gums, also known as gingiva, are the pink tissue above and below our teeth. They are made up of soft tissue lining the mouth and surround the teeth to provide a seal around them. The gums are an important part of the mouth as they help keep our teeth in place. They are also a part of the periodontium, which includes the investing and supporting structures of the teeth. The health of our gums is important as it can have an effect on our general health. While gums are not muscles, the muscles of chewing or mastication are part of an organ known as the masticatory organ, which involves the jaw joint, teeth, gums, bone, and the masticatory muscles.

Gums are made of soft tissue, not muscle
Gums, or gingiva, are the pink-coloured keratinized mucosa that surrounds and protects the teeth. They are made of soft tissue, not muscle, and are perfused by multiple small arteries that originate from branches of the carotid artery.
The gums consist of the mucosal tissue that lies over the mandible and maxilla inside the mouth. They are part of the soft tissue lining of the mouth and surround the teeth, providing a seal around them. The marginal gum is the edge of the gums that surrounds the teeth in a collar-like fashion. The interdental gum lies between the teeth and occupies the gingival embrasure, or the interproximal space beneath the area of tooth contact.
The gums include layers of soft tissue that surround and support the teeth's roots. These layers include the maxillary labial frenum, which is a thin line of soft tissue between the lips and gums, and the alveolar mucosa, a bright red mucous membrane that runs across the floor of the mouth, cheeks, and lips. The marginal gingiva is a strip of soft tissue that surrounds the neck of the teeth and is not bound to them. It is stabilized by the gingival fibres that have no bony support.
Healthy gums are usually coral pink, firm to the touch, and may be naturally darker with melanin pigmentation. Gum health is important, as gum disease can lead to tooth and bone loss. Good oral hygiene practices, such as brushing teeth twice a day, flossing, and using antibacterial mouthwash, can help maintain healthy gums and prevent gum disease.

Gum health and disease can impact general health
Gums, or gingiva, are the soft tissue lining of the mouth that surrounds the teeth and provides a seal around them. They are an important barrier that helps prevent inflammation that may damage your body. Gum health and disease can have a significant impact on general health and quality of life.
Healthy gums are usually coral pink in light-skinned people and may be naturally darker with melanin pigmentation. They are firm to the touch and provide a protective seal around the teeth. However, gum disease, or periodontal disease, can damage this protective barrier and lead to tooth and bone loss. It is a common problem, with an estimated 1 in 7 adults aged 35 to 44 having some form of gum disease, and this number increases with age.
The impact of gum disease goes beyond oral health and can affect the entire body. Advanced gum disease, if left untreated, can lead to severe health consequences, including an increased risk of heart disease, stroke, diabetes, and respiratory issues. The bacteria from infected gums can enter the bloodstream and travel to the heart, increasing the risk of heart attacks and strokes. Additionally, gum disease has been linked to other health problems such as premature births or low-birth-weight babies.
Practicing good oral hygiene is crucial for maintaining gum health. This includes brushing teeth at least twice a day, flossing daily, and using antibacterial mouthwash to reduce plaque buildup. Quitting smoking and maintaining a healthy diet low in sugar and high in whole grains can also help protect the gums and overall health.
It is important to pay attention to gum disease symptoms like bleeding gums, swelling, and bad breath. Seeking early treatment and effective management of gum disease can help prevent serious health complications and protect overall health and quality of life.

Gum disease can lead to tooth and bone loss
Gums are the pink tissue just above and below the teeth. They are part of the soft tissue lining of the mouth and surround the teeth to provide a seal around them. The gums are tightly bound to the underlying bone, which helps resist the friction of food passing over them.
Gum disease, or periodontal disease, is an infection of the gums that can affect the bone structure supporting the teeth. It starts with bacteria on the teeth that get under the gums. If the bacteria stay on the teeth for too long, layers of plaque and tartar develop, leading to early gum disease, or gingivitis. When gum disease progresses, the gums can pull away from the teeth, forming spaces that get infected. This is severe gum disease, or periodontitis.
Periodontitis affects more than 47% of adults over 30 in the US, increasing to around 70% for adults 65 and over. If left untreated, periodontitis can erode the bone supporting the teeth, leading to tooth loss. In fact, periodontal disease is the most common cause of tooth loss among adults. The bone and tissue that hold teeth in place can break down, and teeth may need to be pulled out.
Good oral hygiene is the best way to prevent and treat gum disease. This includes brushing teeth at least twice a day, flossing daily, and using an antibacterial mouthwash. Regular dental check-ups and cleanings are also important, and dentists can recommend personalized oral care plans.

Gum colour can vary and may indicate inflammation
Gum health is directly related to overall health. The gums are the soft mucous tissue that covers the root of the teeth inside the mouth. They surround the teeth and provide a seal around them. Healthy gums are pink and firm to the touch. They help keep your teeth in place.
However, gum colour can vary and may indicate inflammation. Healthy gums usually have a colour described as "coral pink". Other colours like red, white, and blue can signify inflammation (gingivitis) or pathology. Colour variation can be due to factors such as thickness and degree of keratinization of the epithelium, blood flow to the gums, natural pigmentation of the skin, disease, and medications.
For instance, oral candidiasis can cause gums to appear white or red. Anemia, a condition resulting from a lack of red blood cells, can also cause white gums. Canker sores, which usually heal within one to two weeks, are another common cause of white gums. If canker sores do not go away within this timeframe, they could indicate a more serious underlying condition.
Yellowing of the gums is another sign of gingivitis. As the condition progresses, the gums may turn completely purple, or bruising may appear in some parts of the mouth.

The masticatory organ includes the jaw joint, teeth, gums, bone and muscles
The masticatory organ, or the chewing organ, includes the jaw joint, teeth, gums, bone, and muscles. This complex system is responsible for the mechanical process of chewing and grinding food to aid in digestion.
The gums, or gingiva, are an essential part of this system. They are the pink mucosal tissue that lies over the mandible and maxilla, or jawbones, inside the mouth. Gums surround the teeth and provide a seal, helping to keep them in place. The marginal gum is the edge of the gums that surrounds the teeth in a collar-like fashion. The attached gums are resistant to the forces of chewing and are covered in keratin. Healthy gums are usually coral pink, although this can vary due to factors such as skin colour, thickness of the epithelium, blood flow, and natural pigmentation.
The jaw joint, or temporomandibular joint (TMJ), is the site of muscle attachment and movement. The muscles of mastication, or chewing, originate from the surface of the skull and attach to the rami of the mandible at the TMJ. These include the masseter, temporalis, medial pterygoid, and lateral pterygoid muscles. They work in coordination, with one muscle relaxing and another contracting, to produce movements such as elevation, depression, protrusion, retraction, and side-to-side motion.
The teeth are anchored to the jawbones by the periodontal ligament, a soft connective tissue. They work together with the muscles of mastication to enhance the grinding of food. The teeth's ligament also contains pressure sensors that send sensory information to the brain, allowing it to assess what is being eaten and coordinate the muscles' movements and forces.
Overall, the masticatory organ is a complex system of bones, joints, muscles, gums, and teeth that work together to facilitate the essential process of chewing and grinding food for digestion.
