Amalgam filling: giving overall darker appearance to the tooth. Amalgam fillings often stain the tooth they are placed in. [11] This is most noticeable in very old fillings, as pigment slowly leaches out of the amalgam filling material and its associated corroded surfaces. In addition, metallic fillings cast a shadow that can be visible through ...
In dental enamel, fluorosis causes subsurface porosity or hypomineralizations, which extend toward the dentinal-enamel junction as the condition progresses and the affected teeth become more susceptible to staining. Due to diffusion of exogenous ions (e.g., iron and copper), stains develop into the increasingly and abnormally porous enamel. [7]
Tooth whitening or tooth bleaching is the process of lightening the colour of human teeth. [1] Whitening is often desirable when teeth become yellowed over time for a number of reasons, and can be achieved by changing the intrinsic or extrinsic colour of the tooth enamel . [ 2 ]

Silver diammine fluoride (SDF), also known as silver diamine fluoride in most of the dental literature (although this is a chemical misnomer), is a topical medication used to treat and prevent dental caries (tooth decay) and relieve dentinal hypersensitivity. [1]
Remineralization is a natural process and does not have to involve fluoride. 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 ...
“Cleaning the enameled cast iron can help prevent it from chipping and make the equipment last a lot longer,” says Vera Stewart, Cookbook Author and Host of The VeryVera Show and Cookbook ...
Compomers and glass ionomer cements are able to release fluoride over extended periods, and this may help to reduce the risk of a tooth decaying further. However, such a property does not negate the need for excellent oral hygiene to prevent oral disease. [1] [3] Compomers are recommended for patients at medium risk of developing dental caries. [2]
