Intact teeth are white with a tint of blue white for temporary teeth, and whitish gray or even yellow for permanent teeth. Teeth colors can change due to different endogenous factors. Teeth can be pink if there is bleeding pulp during virus influenza or cholera. Yellow teeth are a sign of jaundice. This is after pulp necrosis where putrid products touch the tooth because of dental canaliculas and enamel tarnishes.
There are many external factors that can change teeth color, even some foods, like coffee, tea, and some medications. Some types of berries can change the enamel to bluish-black; the colors are bilberry, and bird cherry.
Medications from oral rinsing agents or a bath color teeth and the tunica mucosa in your mouth turn teeth yellow or brown for a short period of time. They are ethacrynic lactate, and potassium permanganate. Black teeth can occur after chlorhexidine rinsing. Lead teeth colors the dental cervix in a purple color.
Some medications used for endodontic procedures can also change the normal color of enamel and dentine.

The low quality by separating materials during the copper or silver amalgam filling causes the black color of the tooth crown.
Small metallic endodontic instrument parts, like the root needle and pulp extractor causes the oxidation in the canal or in the metal base posts because fillings can darken the tooth.
Smokers seem to have either brown or black teeth. A thick dental deposit and smoking deposit is remover by an excavator and then the teeth are cleaned by a special brush with rubber cups and abrasive pastes. A frequent use of pumice can damage enamel. After the polishing is performed, the gum side is treated with hydrogen peroxide or iodine alcoholic solution. A crown color change that is whitening by hydrogen peroxide solution is very effective.
The temporary teeth crown color changes can be caused by hemolytic syndrome and hemolytic jaundice by different etiology. The indirect reacting bilirubin generated during deposits in tooth tissues and causes its coloring in different tints and many effect a histogeny process and cause enamel underdevelopment. It differs from the hyperplasia caused by Rh-incompatibility of mother and child.
