Tooth discolouration can appear in various forms, from bright white spots to yellowish or dark brown stains. White spots are often early signs of enamel decay or may be related to how the tooth formed. Brown or yellow stains are frequently external, caused by foods, drinks, or habits that deposit pigments onto the surface of the enamel.
In the Indian context, frequent consumption of tea, coffee, or foods containing strong natural dyes like turmeric can lead to surface staining. Furthermore, the use of tobacco or betel nut products is a major cause of deep, stubborn brown or black staining. These habits not only affect the appearance of the teeth but can also impact the health of the underlying tooth structure.
A dentist will diagnose the type of discolouration by examining the teeth and reviewing your lifestyle habits. They will distinguish between extrinsic stains, which sit on the surface, and intrinsic stains, which are inside the tooth. For example, white spots might be assessed to see if they are soft, indicating active decay, or hard, indicating a past mineral loss.
It is important to have discolouration checked by a professional rather than using home whitening kits without advice. A dentist can determine if the stain is a sign of decay that needs a filling or simply a cosmetic issue that can be resolved with professional cleaning. Regular check-ups help maintain the natural brightness of your smile.
