“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 ...
Heavy staining and calculus deposits exhibited on the lingual surface of the mandibular anterior teeth, along the gumline Calculus deposit (indicated with a red arrow) on x-ray image. In dentistry, calculus or tartar is a form of hardened dental plaque.
A veneer is a very thin shell of porcelain that can replace or cover part of the enamel of the tooth. Full-porcelain restorations are particularly desirable because their color and translucency mimic natural tooth enamel. Another type is known as porcelain-fused-to-metal, which is used to provide strength to a crown or bridge. These ...
The enamel on primary teeth has a more opaque crystalline form and thus appears whiter than on permanent teeth. The large amount of mineral in enamel accounts not only for its strength but also for its brittleness. [6] Tooth enamel ranks 5 on Mohs hardness scale (between steel and titanium) and has a Young's modulus of 83 GPa. [4]
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 cause of cavities is acid from bacteria dissolving the hard tissues of the teeth (enamel, dentin and cementum). [4] The acid is produced by the bacteria when they break down food debris or sugar on the tooth surface. [4] Simple sugars in food are these bacteria's primary energy source and thus a diet high in simple sugar is a risk factor. [4]
Amelogenesis is the process of forming tooth enamel, the hard, protective outer layer of teeth. [1] This process begins during tooth development after the initial formation of dentin (dentinogenesis), the layer beneath the enamel. [2]
The pathological wear of the tooth surface can be caused by bruxism, which is clenching and grinding of the teeth. If the attrition is severe, the enamel can be completely worn away leaving underlying dentin exposed, resulting in an increased risk of dental caries and dentin hypersensitivity. It is best to identify pathological attrition at an ...
