The sublingual saliva glands empty through a series of tiny ducts in the tissue on either side of Wharton's ducts. The tongue is attached to the floor of the oral cavity by the frenulum. Sketch of an open mouth showing the frenulum and surrounding structures. Superficial veins run through the base of the frenulum known as varicosities.
This is referred to as a white spot lesion, an incipient carious lesion, or a "micro-cavity". [13] As the lesion continues to demineralize, it can turn brown but will eventually turn into a cavitation ("cavity"). Before the cavity forms, the process is reversible, but once a cavity forms, the lost tooth structure cannot be regenerated. A lesion ...
Plaque that remains in the oral cavity long enough will eventually calcify and become calculus. [18] Calculus is detrimental to gingival health because it serves as a trap for increased plaque formation and retention; thus, calculus, along with other factors that cause a localized build-up of plaque, is referred to as a secondary aetiology of ...
Oral The side of a tooth adjacent to (or the direction toward) the oral cavity, as opposed to buccal, labial or vestibular, which refer to the side of a tooth adjacent to (or the direction toward) the inside of the cheek, lips or vestibule respectively. Oral includes both palatal and lingual.
The oral mucosa is the mucous membrane lining the inside of the mouth. It comprises stratified squamous epithelium, termed "oral epithelium", and an underlying connective tissue termed lamina propria. [1] The oral cavity has sometimes been described as a mirror that reflects the health of the individual. [2]
Fluoride is commonly found in toothpastes. Fluoride can be delivered to many parts of the oral cavity during brushing, including the tooth surface, saliva, soft tissues and remaining plaque biofilm. [4] Some remineralization methods may work for "white spot lesions" but not necessarily "intact tooth surfaces". [19]
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 ...
It is possible for the soft palate to retract and elevate during speech to separate the oral cavity (mouth) from the nasal cavity in order to produce the oral speech sounds. If this separation is incomplete, air escapes through the nose, causing speech to be perceived as nasal .
