There are many reasons as to why our teeth could lose their natural white colour. The most common one is poor maintenance, other include:
– Eating & drinking the wrong foods
– Health issues
Not brushing your teeth for two or three times a day as recommended can give your teeth an unflattering look. The foods we eat and drink can also have an effect, for example drinks high in colouring such as red wine and blackcurrant juice can contribute to the overall colour of your teeth.
It’s a well known fact that one of the side effects of smoking is yellow teeth. Our teeth also tend to darken and yellow with age. Some antibiotics can cause the teeth to darken and some people naturally have a darker grey shade.
One of todays most popular ways of improving the colour of your teeth, and achieve that winning smile is to have them whitened. Teeth whitening can be a great way of lightening the natural colour of your teeth without causing any harm or damage. In most cases, the original tooth shade is whitened to a lighter colour, rather than being turned completely white. The most usual tooth whitening process is usually professional bleaching-though your dentist will assess you first and let you know which process is most suitable for you, or if they recommend tooth whitening at all. The most common type is known as “dentist-supervised home whitening” which involves having trays made specifically to fit your mouth, rather like gum shields. The gel is then inserted into the trays and you will have a routine to follow at home.
The “active ingredient” in the whitening product tends to be hydrogen peroxide or carbamide peroxide. As it is broken down, oxygen makes its way into the enamel and dentine of your teeth, which causes your teeth colour to lighten.
