Sometimes, small white spots appear on the fingernails or toenails. This phenomenon is quite common and can cause concern. Many people immediately assume it’s a calcium deficiency or a health problem. However, the reality is often simpler.
In most cases, these marks are harmless and gradually disappear as the nail grows out. They are usually related to minor trauma or certain daily habits.
Let’s explore together the possible causes and what these stains might actually mean.
What are the white spots on the nails?
The white spots visible on the nails are called leukonychia in the medical field. They can appear as small dots, streaks, or sometimes larger areas.
This phenomenon occurs when the nail structure is slightly disrupted during its formation. The nail is composed of layers of keratin produced by the matrix at its base. When a minor impact or irritation affects this area, tiny air spaces can appear between these layers, creating the whitish appearance visible on the surface.
In most cases, these brands pose no health risks.
