Why teeth start to darken: the main reasons and recommendations

A change in the color of tooth enamel often signals internal pathologies or a violation of oral hygiene. The darkening of the crowns spoils the aesthetics of the smile and indicates the need for dental intervention.
Attempts to whiten teeth with abrasive pastes on their own often exacerbate the problem by damaging the protective layer. To effectively restore the natural shade, it is necessary to determine the exact cause of pigmentation.
External factors of enamel pigmentation
Coloring substances from food and beverages easily penetrate into the microcracks of the enamel, gradually changing its original color. Products with a high content of tannins and acids, which soften the surface layer of the tooth, are particularly dangerous. Regular consumption of such products leads to the formation of persistent plaque. The main external sources of staining include:
- strong black tea and natural coffee;
- red wine and carbonated drinks with dyes;
- tobacco smoke containing tar and nicotine;
- berries with dark pigment like blueberries.
Systematic contact with these substances forms a dense pigmented film that cannot be removed with a conventional brush. The accumulation of plaque contributes to the development of caries and gum inflammation.
Internal pathologies and structural changes
Darkening of the tooth from the inside is often associated with necrosis of the pulp after injury or poor-quality canal treatment. A depulpated tooth loses its natural nutrition and eventually turns gray or brown. Systemic factors that change the structure of hard tissues during their formation also have an impact. Dentists identify the following internal causes of darkening:
- excess fluoride in drinking water, causing fluorosis;
- taking certain antibiotics during the period of tooth formation;
- age-related thinning of enamel and exposure of yellow dentin;
- genetic disorders of the development of hard tissues.
When the enamel is thinned, the dentin begins to shine through more, which makes the teeth appear yellow. The use of bleaching strips in this case does not bring results and harms the exposed tissues.
Professional methods of color restoration
To restore the teeth to a healthy appearance, it is necessary to carry out a complete rehabilitation of the oral cavity in the clinic. The dentist selects the treatment method based on the diagnosis of the causes of darkening of the enamel. Ultrasonic cleaning and polishing using Air Flow technology is effective for surface staining.
To remove deep stains, office chemical or laser bleaching is used under the supervision of a doctor. In cases where it is impossible to change the color by therapeutic methods, defects are masked with veneers or crowns made of zirconium dioxide. The cost of such structures ranges from 25,000 to 45,000 rubles per unit.
Regular occupational hygiene every six months prevents deep staining and allows you to detect caries at an early stage. Timely care preserves dental health without radical prosthetics. Juega en Spartans casino y pon a prueba tu suerte.
