Examples include iron (black stain), iodine (black), copper (green), nickel (green) and cadmium (yellow-brown). [3] Antibiotics.

The perception of tooth colour is multi-factorial. Reflection and absorption of light by the tooth can be influenced by a number of factors including specular transmission of light through the tooth; specular reflection at the surface; diffuse light reflection at the surface; absorption and scattering of light within the dental tissues; enamel mineral content; enamel thickness; dentine colour ...

Before iron deficiency anemia sets in, “the body will do everything it can to retain the right number of red blood cells. So, it will deplete the storage iron before it depletes the red blood ...
An increase in acidity at the tooth surface can induce demineralization and softening, therefore leaving the tooth structure susceptible to abrasive factors such as tooth brushing. [18] When the surface of the tooth structure is softened by acid, mechanical forces such as brushing can cause irreparable damage on tooth surface.
Rare but serious allergic reactions are possible; symptoms include itching, swelling, and difficulty breathing. Certain formulations of stannous fluoride in dental products may cause mild tooth discoloration; this is not permanent and can be removed by brushing, or can be prevented by using a stabilised stannous fluoride toothpaste.
