What causes teeth to discolour?
Baby (or deciduous) teeth are whiter than the adult teeth that replace them. As we age our teeth become naturally darker, yellower or stained through consumption and lifestyle factors. This is why white teeth are considered younger, more attractive teeth.
Most people believe a good smile and healthy teeth are important social assets that make you more attractive. This attitude extends to a belief that an unattractive smile will hurt someone’s chances at career success and promotion. When asked, most people will say that having whiter teeth is the single thing that would most improve their smile.
The main causes of perceived teeth discolouration are genetics: some natural teeth are just darker in appearance than others. Also, antibiotics can affect tooth colour, certain foods stain teeth more than others and all teeth get darker as we age.
There are two types of teeth discolouration: internal and external. Internal tooth discolouration is found in the enamel and the dentin of the teeth. The causes of internal teeth discolouration are tetracycline, using antibiotics as a child, high levels of fluoride, tooth decay, developmental disorders, root canal problems and trauma.
External discolouration is caused by foods with tannins, tea, coffee, carrots, oranges and other types of foods such as curry. Wine and tobacco also stain teeth and lead them to becoming discoloured. It’s important to talk to your dentist about how your teeth discolouration can be resolved.
Having white teeth gives the impression of youthful teeth untouched by the excesses of tea, coffee, wine and the passing of time. Having your teeth whitened is one of the most economical ways to enhance your smile.Leave a reply →
