Permanent teeth, over time, often become darker or off-coloured due to food staining, tobacco, and changes in their mineral composition. Over time enamel becomes less porous due to the mineralization of enamel and dentinal tubules. By dental bleaching, we can improve aesthetics and overcome this problem.
Bleaching can be done by application of bleaching agent and holding it over the tooth surface by cosmetic dentistry professional or at home. Tooth shade gradually lightens by an oxidizing agent, hydrogen peroxide, and carbamide peroxide. Gradual penetration of porous enamel by activating agent results in teeth being whitened. If the bleaching agent reaches dentin teeth will be whiter. Frequency and period application plus the degree of staining determines the bleaching period. Try to avoid drinking coffee and smoking. Root canal-treated teeth tend to be dark or chocolate brown. These dark teeth can be bleached. We usually isolate dark teeth with a rubber dam prior to bleaching.
Is bleaching safe?
Mild thermal sensitivity is a common side effect of office and home bleaching. However, no long-term tissue effects have been demonstrated.
Composite resin bonding can be used for reshaping, recontouring, closing diastema, restoring decay, and correcting minor tooth imperfections. A thin layer of the composite layer can be used as a composite laminate to improve tooth appearance.
Tooth contour, colour, size, and shape play a great role in our smile, especially where our first impression is important for us. Since porcelain laminate cannot be stained, discoloured, and provide a highly polished surface they are highly recommended. It can produce texture and translucency that is close to natural tooth enamel.
Porcelain veneers are one of the least invasive procedures to improve esthetic on the visible surface of the tooth. A porcelain veneer can give the impression of a long and highly translucent tooth structure that can match adjacent teeth.
Full porcelain crowns and porcelain fused to metal crowns are popular these days. Procera Alumina and zirconium can be used where the aesthetics and strength of a crown are a concern. Depending on the patient’s need for aesthetics or strength we can choose the proper crown type. Procera Alumina provides a high translucent surface for front teeth.
