Healthy gums fill and fit each space between the teeth, unlike the swollen gum papilla seen in gingivitis or the empty interdental embrasure seen in periodontal disease. Healthy gums hold tight to each tooth in that the gum surface narrows to "knife-edge" thin at the free gingival margin. On the other hand, inflamed gums have a "puffy" or ...
Human teeth function to mechanically break down items of food by cutting and crushing them in preparation for swallowing and digesting. As such, they are considered part of the human digestive system. [1] Humans have four types of teeth: incisors, canines, premolars, and molars, which each have a specific function. The incisors cut the food ...
A 1930s poster from the Work Projects Administration promoting oral hygiene. Tooth decay is the most common global disease. [14] Over 80% of cavities occur inside fissures in teeth where brushing cannot reach food left trapped after eating and saliva and fluoride have no access to neutralize acid and remineralize demineralized teeth, unlike easy-to-clean parts of the tooth, where fewer ...
Signs that you might benefit from deep dental cleaning. Healthy gums should look pink and tight around the teeth, Cram explains. If you develop gum disease, the look and feel of your gums will ...
Diagram of tooth anatomy. Dental anatomy is a field of anatomy dedicated to the study of human tooth structures. The development, appearance, and classification of teeth fall within its purview. (The function of teeth as they contact one another falls elsewhere, under dental occlusion.)
In theory, gingival fibers are the protectors against periodontitis, as once they are breached, they cannot be regenerated.When destroyed, the gingival sulcus (labelled G in the diagram) increases in depth apically, allowing more debris and bacteria to remain in intimate contact with the delicate sulcular and junctional epithelia for longer times.
The reversible inflammation of the gums is easily prevented by patients. After the removal of the inflammatory product, usually plaque or calculus, this allows the gums room to heal. This is done by patients thoroughly cleaning teeth every day with a soft bristle toothbrush and an interdental aid.
This nerve runs inside the mandible, within the inferior alveolar canal below the mandibular teeth, giving off branches to all the lower teeth (inferior dental plexus). [ 5 ] [ 6 ] The oral mucosa of the gingiva (gums) on the facial (labial) aspect of the maxillary incisors , canines and premolar teeth is innervated by the superior labial ...
