Why would my toenails be splitting?

Split nails are common. They can affect both fingernails and toenails and are usually the result of physical trauma, such as an object crushing them. However, wear and tear, as well as nutrient deficiencies, are also potential causes. In some cases, a person can take preventive measures to avoid splitting their nails.

Is a cracked toenail serious?

There are many things that can cause this, from aging to fungal infection to trauma. Sometimes cracked toenails are merely an aesthetic concern and heal quickly and naturally on their own; however, if the crack is severe, the toenail may split down the middle of the nailbed or even detach from the nailbed.
