Often the change of the enamel color occurs not due to improper care of teeth or its complete absence. In this article, we have tried to consider each possible color option and the reasons for its appearance. So the article will be informative not only for those who want to prevent such a defect of their teeth, but also for those who are already faced with the phenomenon of teeth changing colour, but still cannot accurately determine the source of the problem.
Tooth enamel is almost transparent due to its composition. Its natural color is hereditary and can be pure white, yellowish-white and white-blue. It is believed that the enamel with natural yellowness is much stronger than the bluish one. However, it is dentin that gives main color to the tooth. So if teeth are changing colour, become cloudy and there is an unnatural shade, this can indicate the presence of a disease, most often even a hidden one.
Note!In dentistry, the phenomenon of enamel color change is called discolourness. It is divided into the acquired one, which occurred during life and congenital, i.e. inherited or embedded in the mother’s womb due to abnormalities in the development of the fetus.
In addition to possible diseases, teeth discoloration may depend on living (in some areas drinking water is saturated with minerals and salt impurities affecting the color of the teeth), on external influence (harmful production, close location of landfills, warehouses with chemicals), on harmful human habits. Moreover, the environment can affect the manifestation of discoloration no less than any other factor.
The phenomenon of teeth changing colour often occurs due to injury, as a result of contact with dyes in cracks. It is also possible that not the tooth enamel but the plaque on it has changed its color, due to insufficient oral care and constant consumption of food and beverages containing dyes. Treatment in this case is the easiest. It is enough to remove the plaque. Bleaching the enamel does not always have a positive effect if the color is deep.
All of the above factors can lead to the fact that the color of the tooth enamel will be very different from the natural one. Let’s take a closer look at the causes of each of these unnatural shades.
|Red||Hereditary disease porphyria is characterized by violation of pigmentation of the soft tissue. Very often it gives complication on tooth enamel, painting it in red color. Also, the rupture of the pulp pouch and hemorrhage leads to the redness of the enamel with a strong injury to the tooth.|
|Blue||Blue enamel can occur due to necrosis of the pulp associated with both infection and injury. In addition, after the removal of the pulp, the non-viable tooth is changing colour to bluish tint over the years. Blue shades of the enamel are inherent in such a disease as hyperthyroidism. Long-term treatment with tetracycline can also lead to a change in the natural color of the enamel to blue, especially if the drug is used by the mother in the last stages of pregnancy or is prescribed to the child in the first month of life, when the enamel of milk and molars is formed. Tetracycline and minocycline, prescribed to adults for the treatment of arthritis and acne, with long-term use also leads to the formation of bluish spots on tooth enamel. Another reason for this is long-term consumption of water saturated with iron.|
|Green||Green plaque on tooth enamel clearly indicates the presence of a specific fungus. Teeth can turn green in contact with some metals. So in the presence of teeth previously cured with amalgam fillings containing nickel or copper, the enamel can turn green. The same effect occurs in workers of metallurgical enterprises with constant inhalation of vapors containing particles of these metals.|
|Brown||This color of enamel is common for people with bad habits, such as frequent smoking, uncontrolled use of coffee and strong black tea. Brown patina is formed very quickly. Rinse the mouth with a solution of potassium permanganate, the inhalation of fumes of iron, manganese and nickel, long-lasting effects on the body of iodine or chlorinated water also leads to staining of enamel in brown. Carious may at first seem a simple darkening of the enamel to brown. The same effect is sometimes achieved in the presence of acid necrosis.|
|Black||Today, materials that color teeth black are no longer used in dentistry. These include chromic acid, magnesium and silver nitrate. However, still used silver amalgam also eventually leads to blackening of the tooth. Close long-term contact with metals such as iron, manganese, nickel, mercury contribute to the staining of enamel in black.|
|Pink||Injuries, minor damage to the pulp and internal hemorrhage, penetrating into the microcracks of the tooth cavity and dentine tubes, contribute to the staining of the enamel in pink. In this case, the tooth does not necessarily lose its viability. If in the treatment of the canal formalin composition was used, over time, the enamel of the tooth turns pink.|
|Grey||Silver amalgam in contact with enamel at first gives a gray tint, but eventually darkens until black. Necrotic pulp also leads to staining the tooth in dark gray color with the loss of a characteristic healthy shine.|
|Yellow||Injury, prolonged exposure to antibiotics, abuse of sugar-containing products, bad habits, age-related changes in the composition of the enamel, thinning of the enamel layer lead to yellowing of the teeth. In addition, this shade of enamel is inherent in diseases such as Addison’s disease and hematogenous jaundice, as well as problems with the adrenal glands.|
Thus, if you identify that the tooth enamel has changed its color on one or more teeth, you should not only apply for cosmetic treatment, but also understand the root causes of the defect. In the presence of deep discolourness of teeth whitening can often help just to lighten the enamel layer.
