Xerostomia is the subjective sensation of dry mouth, which is often (but not always) associated with hypofunction of the salivary glands. [3] The term is derived from the Greek words ξηρός (xeros) meaning "dry" and στόμα (stoma) meaning "mouth". [4] [5] A drug or substance that increases the rate of salivary flow is termed a sialogogue.
Stomatitis (mouth swelling) Liver failure; Pulmonary oedema (fluid in the lungs) Gastrointestinal bleeding; Pulmonary embolism; Myocardial ischaemia (lack of blood supply to the heart muscles) Speech disorders; Haemoglobin decrease; Proteinuria (protein in the urine; usually indicative of kidney damage)
The condition is difficult to treat, and may involve fillings, fluoride to fight tooth decay and drugs that increase saliva for dry mouth, as well as oral hygiene instruction. It can be dangerous for active methamphetamine users to undergo dental surgery because of the cardiac problems that can result from the interaction of local anesthetic ...
One of the physical changes can be the colour of teeth. Dental erosion can lead to two major tooth colour change – the first being a change of colour that usually happens on the cutting edge of the central incisors. This causes the cutting edge of the tooth to become transparent. [17] A second sign is a yellowish tint on the eroded tooth.
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 ...
The removal of the decayed tooth is performed if the tooth is too far destroyed from the decay process to effectively restore the tooth. Extractions are sometimes considered if the tooth lacks an opposing tooth or will probably cause further problems in the future, as may be the case for wisdom teeth . [ 145 ]
It is considered the main cause of tooth loss for adults worldwide. [7] [8] In its more serious form, called periodontitis, the gums can pull away from the tooth, bone can be lost, and the teeth may loosen or fall out. [5] Halitosis (bad breath) may also occur. [1]
Back teeth showing fissure system. Dental caries is an upset of the balance between loss and gain of minerals from a tooth surface. [3] The loss of minerals from the teeth occurs from the bacteria within the mouth, fermenting foods and producing acids, whereas the tooth gains minerals from our saliva and fluoride that is present within the mouth.
