Stained or discoloured teeth refer to teeth that appear to have a yellow or grey tone, as well as pigmentations on the enamel surface.
External: These stains are often superficial, and commonly caused by highly pigmented food, drinks or tobacco smokes. Treatments for external staining include air polishing, microabrasion techniques and whitening with peroxide.
Internal: This is when the inner part of the tooth, called dentine, has a darker shade. Dark dentine could come from leaky amalgam restorations, post root canal treatment, overexposure to fluoride, antibiotic use in infancy, trauma to teeth or rare genetic conditions such as dentinogenesis imperfecta.
Age-related: This is a combination of the external and internal factors. As teeth age, the enamel thins out, allowing the yellow dentine to show through more easily. On top of this, years of food consumption, drinks and tobacco can add to the gradual discolouration of teeth.
Fortunately, there are many treatment options for stained teeth. A good dental health routine, including twice-daily toothbrushing and daily flossing, can keep your teeth healthy and looking great. Limiting your consumption of teeth-staining food and beverages can help slow down the stain build up. Regular dental whitening treatments or even the use of dental veneers will help keep them looking whiter and brighter.
