Are you fed up of hiding your smile because of stains and discolouration? Do you long for a celebrity smile?
White teeth are an essential part of looking and feeling your best so it’s important to understand why our teeth become stained and consider some of the ways we can fight discolouration.
What causes discoloured teeth?
There are two main types of tooth discolouration:
Extrinsic
This type of discolouration occurs when the enamel is stained by external sources such as coffee, red wine, dark fruits and smoking. Stains form on the surface of the tooth and can darken the tooth shade.
Intrinsic
This is when the layer below the enamel (the dentin) becomes darker or more yellow and could be the result of antibiotics, tooth trauma or exposure to too much fluoride as a child. Age also plays a part here, as when a person ages the outer enamel becomes thinner and allows the dentin to show through.
