With increasing severity, the subsurface enamel, all along the tooth becomes more porous. Enamel may appear yellow/brown with discolouration and/or many pitted white-brown lesions similar to cavities. They are often described as "mottled teeth". [8] Fluorosis does not cause discolouration to the enamel directly, as upon eruption into the mouth ...
“If you have exposed dentin, very thin enamel, exposed cavities or root surfaces showing, the acid in whitening strips can erode more tooth structure than can be remineralized and so should be ...
Tooth remineralization is the natural repair process for non-cavitated tooth lesions, [1] [2] in which calcium, phosphate and sometimes fluoride ions are deposited into crystal voids in demineralised enamel. Remineralization can contribute towards restoring strength and function within tooth structure.
The discoloration of teeth over time can result from exposure to substances such as tobacco, coffee, and tea. [43] The staining occurs in the interprismatic region internally on the enamel, which causes the tooth to appear darker or more yellow overall.
Acid erosion is a type of tooth wear.It is defined as the irreversible loss of tooth structure due to chemical dissolution by acids not of bacterial origin. [1] Dental erosion is the most common chronic condition of children ages 5–17, [2] although it is only relatively recently that it has been recognised as a dental health problem. [3]
It is the primary pathological cause of tooth loss in children. [149] Between 29% and 59% of adults over the age of 50 experience caries. [150] Treating dental cavities costs 5–10% of health-care budgets in industrialized countries, and can easily exceed budgets in lower-income countries. [151]
Discoloration of the front teeth is one of the most common reasons people seek dental care. [10] However, many people with teeth of normal shade ask for them to be whitened. [10] Management of tooth discoloration depends on the cause. Most discoloration is harmless and may or may not be of cosmetic concern to the individual.
Abfraction is a form of non-carious tooth tissue loss that occurs along the gingival margin. [2] In other words, abfraction is a mechanical loss of tooth structure that is not caused by tooth decay, located along the gum line. There is theoretical evidence to support the concept of abfraction, but little experimental evidence exists. [3]
