Tooth Discolouration: Why Teeth Change Colour and How to Restore Your Bright Smile
Many people notice their teeth darkening or becoming stained over time, even if they brush and floss daily. At Tooth Harmony in Niagara Falls, we often see patients who are worried about tooth discolouration and want to know what’s causing it—and more importantly, what can be done about it.
Here’s what you need to know.
What Is Tooth Discolouration?
Tooth discolouration is any change in the natural colour or brightness of your teeth. It can appear as yellowing, brown spots, grey tones, or even dark streaks.
There are two main types:
Extrinsic Discolouration – Stains on the outer enamel surface
Intrinsic Discolouration – Colour changes within the tooth structure itself
Common Causes of Tooth Discolouration
Several factors can contribute to staining or dulling of your teeth:
Foods & Drinks – Coffee, tea, red wine, and dark berries can leave lasting stains.
Tobacco Use – Smoking or chewing tobacco can cause stubborn yellow or brown stains.
Poor Oral Hygiene – Infrequent brushing and flossing allow plaque and tartar to build up.
Ageing – Enamel naturally thins over time, revealing more of the yellowish dentin beneath.
Medications – Certain antibiotics or high-fluoride exposure during childhood can affect colour.
Trauma – A tooth injury can cause internal darkening.
Genetics – Some people naturally have darker enamel shades.
