A lot of different colours and pigments can stick to the organic matter in your teeth and change the colour or stain them. There are two main ways to get rid of these stains: physically removing them and chemical cleaning.
Physical removal is a way to get rid of superficial stains, which are the everyday spots that build up on the surface over time. This method uses roughness to get rid of these small flaws on the surface.
Chemical bleaching, on the other hand, is a complete answer that gets rid of both surface stains and stains that are deeply embedded in the tooth enamel. It's not only the most popular way to whiten teeth, but it's also the best way to do it. It can make your smile look younger by getting rid of stains on the surface and deep inside your teeth.
