Tooth Discolouration

Teeth change colour throughout life, and this happens for several reasons. Some discolouration sits on the surface and comes from outside; other staining lies within the tooth itself. Knowing the difference is the key to choosing the right — and most conservative — solution.

Common causes

Colour changes fall into a few main categories:

• Age. Enamel becomes thinner over the years, allowing the naturally yellowish dentine to show through more clearly.
• Lifestyle. Coffee, tea, red wine, and smoking stain teeth over time. This type usually responds well to whitening.
• Injury. A previous knock to a tooth can cause internal discolouration, making that tooth darker than its neighbours.
• Developmental. Disruptions to enamel formation while the tooth was developing can result in spots or chalky white patches.

How we can help

We begin by identifying where the colour originates, as that determines what will work. If it comes from the outside, whitening is often sufficient. When it lies deeper, a veneer or crown can deliver a calm, natural-looking result. We present all the options and find the one that suits your smile.
