When you look into the mirror, it feels very disturbing to see yellow or even slightly discoloured teeth. Here are few reasons that cause teeth discolouration.
Sometimes, tooth colour runs in the family. This colour varies across a spectrum from light to dark. Reddish brown, light yellow, light grey and white are the four natural shades and this depth of colour varies across a spectrum from light to dark.
Teeth look yellow when the enamel is thin and the dentin underneath shows through it. Dentin is a deep yellow to brownish material inside your teeth under the enamel, and it is often responsible for the yellow you see when you look in the mirror.
3. Wear and tear
Teeth ultimately turn yellow as you get older; when the enamel wears away from chewing and exposure to acids from food and drink. Most teeth turn yellow as this enamel thins with age, but some take on a greyish shade when mixed with a lasting food stain.
Nicotine from smoking does not just develop an unhealthy addiction; it leaves yellowish or brownish surface stains on your teeth.
