Total discoloration of the tooth depends on the color and translucency of the outer layers (enamel), and the color of the layer beneath the enamel (or dentine dentin), which is compared to enamel yellow and in varying degrees shows through the surface. Based on various influences, the color may change.
The main influences are:
- Poor hygiene
- colored drinks (coffee, tea, red wine)
- hereditary disposition
Surface staining of teeth
The stain on the enamel maybe caused by pigments of various snacks, beverages and habits. Especially smoking, coffee, tea, red wine, yellow spice, or other strongly colored foods. Such pigmentation is possible to remove mechanically, because they are on the enamel surface.
Effective methods, performed by dental hygienist are:
1) brushing and abrasive paste – at a smaller incidence or children
2) Air-flow, or sandblasting – at a higher incidence of pigmentation
Discoloration, which are more durable and can be found in the deeper layers of enamel can’t be eliminate with this treatment.
To keep a color of teeth retained, it is necessary to properly care for teeth and remove dental plaque regularly. If there is a plaque on the teeth, the teeth are dull and rugged and much more susceptible to other resettlement of other pigments.
Deep tooth discoloration
During the development of second teeth in childhood a number of factors can affect the future color – some medications, especially tetracycline antibiotics (discolor teeth yellowish to brown), excessive fluoride intake (remain white spots on teeth).
The discoloration of the teeth, both congenital or affected in early childhood, is stored in a deep layer of enamel and can only be solved by teeth whitening, and if even this does not work, the other solution is the aesthetic correction of a dentist (fillings, veneers, crowns)
Aging – as we are gradually aging, the color of teeth is changing gradually to yellow, later to gray – it’s physiologically natural process that can alleviate by whitening.
Dead teeth (after removal of infected pulp tissue, after injuries teeth) are manifested by greyish to blackish appearance. This coloration can be solved via internal teeth whitening, when the bleach product is repeatedly applied directly into the canal.
