From the outmost layer to inner structure, a tooth consists of the transparent enamel, the slightly yellowish dentin, and the inner pulp tissues. The color of human teeth generally ranges from ivory white to light yellow and those with thicker enamel layer tend to have whiter teeth. There are 16 shades in teeth color, most people falls into the 4 levels between A3 and A3.5.
However, there are other factors that often discolor our teeth. One of the common causes include pigmentation from food and drinks, such as tea, coffee, cola, red wine, curry, and chocolate. Smoking is another source that affects teeth color. In addition, tooth decay, periodontal disease, or excessive use of fluoride toothpaste can cause little white spots on teeth surface, known as dental fluorosis. Long term treatment on Bronchitis with the antibiotic “Tetracycline” or simply aging can also turn teeth yellow.
