A great challenge for dentists has always been the elimination of possible stains or stains of the teeth. Among the multiple causes that give rise to these dental stains are: direct trauma, chronic dental infections, incomplete dental development, tobacco use or certain antibiotics such as tetracyclines, dental mouthwashes with chlorhexidine, among many others. Two types of dental stains can be different. On the one hand, extrinsic pigmentations, which are located in the most superficial layer of the tooth, known as tooth enamel. These types of stains are those produced mainly by tobacco, as well as coffee, tea, red wine, etc.
On the other hand, intrinsic pigmentations are found, which affect deeper dental layers of the tooth, such as dentin. This type of staining refers to those caused by taking certain antibiotics or dental trauma, among others. This second type of staining, intrinsic, is much more difficult to remove and techniques that go beyond dental microabrasion are required. One of the possible treatment alternatives, designed primarily to eliminate the limited coloring defects in the enamel (outer layer of the tooth), is the dental microabrasion.
This technique is based on the removal of the superficial layers of the tooth, to eliminate enamel defects caused by: spots caused by an incomplete development of the tooth (hypoplasias or amelogenesis imperfecta), consumption of fluoride (fluorosis), incipient caries, spots after of an orthodontic treatment etc. The dental microabrasion achieves the elimination of alterations of the tooth color that do not exceed 2mm deep. It is based on a chemical-mechanical technique. First, phosphoric acid is applied to the teeth and then an abrasive paste, which polishes the enamel layers by using rotary instruments with a rubber tip until a uniform color is achieved. Finally, you can apply some teeth whitening session to obtain whiter, aesthetic teeth and achieve complete color uniformity. So, we are facing a very conservative technique, of great success and that guarantees a very aesthetic result.
