Stained or Discoloured Teeth — Effective Treatments

From professional whitening to custom veneers, we have solutions for every type of tooth discolouration

Tooth discolouration is one of the most common cosmetic concerns. The treatment depends on whether stains are extrinsic (on the surface) or intrinsic (within the tooth structure).

Stain Types & Causes

Why Your Teeth Are Discoloured

Extrinsic stains are caused by substances that adhere to the tooth surface — coffee, tea, red wine, tobacco, and certain foods. These stains are typically brown, yellow, or grey and respond well to professional cleaning and whitening.

Intrinsic stains are embedded within the tooth structure, caused by aging, certain medications like tetracycline, excessive fluoride during development, or trauma. Intrinsic discolouration does not respond to surface cleaning and may require whitening, bonding, or veneers depending on severity.

Causes of Discolouration

What Causes Tooth Stains

Surface Staining Causes

Surface staining (extrinsic discoloration) results from external pigments coating the enamel—coffee, tea, red wine, tobacco, and food dyes.

These stains accumulate over time, creating a yellowed or darkened appearance that professional cleaning and whitening can effectively remove.

Daily habits like coffee consumption and tobacco use accelerate surface staining, making consistent oral hygiene and preventive measures important.

Professional whitening treatments penetrate enamel to brighten teeth, removing both surface stains and underlying discoloration from within.

Internal Discolouration

Intrinsic discoloration (internal staining) occurs within the tooth structure, from aging, medication (like tetracycline), or trauma to the nerve.

These deep stains cannot be removed by cleaning alone because they're embedded in the dentin layer beneath the enamel.

Professional whitening may lighten intrinsic stains partially, but severe discoloration often requires cosmetic restoration with veneers or crowns.

Our cosmetic team uses advanced whitening protocols and restorative options to achieve dramatic brightening results tailored to your needs.

Other Intrinsic Causes

Fluorosis (excess fluoride during tooth development), certain antibiotics, systemic diseases, and aging all cause internal tooth discoloration.

Root exposure from gum recession shows the darker, less white dentin layer, creating an appearance of staining.

Enamel hypoplasia (thin or defective enamel from early childhood illness or stress) appears as discolored or chalky areas on teeth.

Our cosmetic dentistry options—professional whitening, bonding, veneers, and crowns—address all causes of discoloration to restore your bright, confident smile.
