A black spot on your tooth can be alarming, but it doesn’t always mean serious trouble. The cause ranges from surface staining to deep decay, and the right treatment depends on what’s behind the discolouration.
Common Causes of Black Spots on Teeth
The most common causes include tooth decay (cavity), tartar build-up (calcified plaque can appear dark), surface staining from coffee, tea, red wine, or smoking, old amalgam (metal) fillings showing through enamel, and tooth trauma causing internal discolouration from a damaged nerve.
When to Worry
If the black spot is soft or sticky when you touch it with your tongue, it’s likely a cavity that needs prompt treatment. If it’s hard and flat, it may be calculus (tartar) that a hygienist can remove. Dark staining without structural damage is a cosmetic issue rather than a health emergency.
Treatment Options
For decay: fillings, crowns, or root canal treatment depending on depth. For staining: professional cleaning, teeth whitening, or composite bonding to cover persistent discolouration. For old fillings: replacement with tooth-coloured composite or ceramic restorations.
