Single Dark Tooth: see it on your own smile first
Lighten one darkened tooth so it matches the teeth beside it.
A single tooth that's turned grey or dark, usually after a knock or a root canal, draws attention out of all proportion to its size — because smiles read as a set, and one odd member breaks the set.
Dentists typically treat it with internal bleaching (whitening the tooth from inside, if it's had root canal treatment), external whitening focused on that tooth, or a veneer or crown when the discolouration won't lift. The right option depends on why the tooth darkened, which is exactly what an exam establishes.

The honest limits of this preview
Cosmetic visualisation of internal bleaching. Not a diagnosis of the underlying cause. A preview can't see bone, bite, gum health or anything beneath the surface — only a clinical exam can. Treat it as a conversation starter for your dentist, never as a promised result.
Worth asking your dentist
- Why did this tooth darken, and is the tooth itself healthy?
- Am I a candidate for internal bleaching, or is this a veneer/crown conversation?
- How close a colour match to the neighbouring teeth is realistic?
