It’s easy to overlook a small dark mark on your tooth and assume it’s nothing serious. If there’s no pain or sensitivity, many people choose to ignore it.
However, what looks like a minor surface stain can often be the beginning of a much larger problem inside the tooth.
A small black spot is often just the visible tip of decay. Beneath the surface, the cavity may have already spread through the enamel into the dentine.
Tooth decay doesn’t always cause symptoms early on, which is why it can progress unnoticed.
In this case, the images show how a seemingly small area of decay can be much more extensive once treatment begins:
Before treatment – a small dark spot on the tooth with a grey area surrounding it

During treatment – the decay is carefully removed, revealing a larger cavity beneath the surface

After treatment – the tooth is restored with a natural-looking filling

Regular dental check-ups and dental exams allow problems like this to be identified early. Treating decay at an early stage usually means a simple filling.
If left untreated, the decay can progress deeper, potentially leading to more complex treatments such as root canal therapy or even tooth loss.
Even small changes in your teeth should be assessed. This includes:
Early assessment by a dentist can prevent more extensive treatment later.
