Nail pitting
Dents in the nail beds can be shallow or deep and found on various parts of the nail in different directions. This condition is known as nail pitting. It is caused by an issue with how the layers in the superficial nail plate develop. The superficial nail plate is the hard part of the nail that is made up of a type of protein known as keratin, which also comprises your hair and skin. The superficial nail plate protects the skin underneath.
If you notice dents in your nails, it is important to see a board-certified dermatologist for a diagnosis and treatment. Treatment can help prevent the disease from worsening and make you feel more comfortable.

Spoon nails
Dents in the nail beds can be shallow or deep and found on various parts of the nail in different directions. They can be caused by dermatological conditions, autoimmune diseases, malnutrition, endocrine disorders, and nutritional deficiencies. Spoon nails are a type of nail denting that can be caused by chronic iron deficiency, malnutrition, endocrine disorders, autoimmune conditions, and nutritional deficiencies.
Chronic iron deficiency is one of the main causes of spoon nails. Iron deficiency can lead to a decrease in red blood cell production, which can affect the oxygen-carrying capacity of the blood. This can result in a decrease in oxygen delivery to the nails, which can cause the nail bed to become depressed and the rest of the nail to appear elevated.
Other conditions that can lead to malnutrition, such as celiac disease, can also cause spoon nails. Celiac disease is an autoimmune disorder that affects the small intestine's ability to absorb nutrients from food. This can result in a deficiency of essential nutrients, including iron, which can affect nail health.
Endocrine disorders, such as hypothyroidism, can also cause spoon nails. Hypothyroidism is a condition in which the thyroid gland does not produce enough thyroid hormones. These hormones are important for regulating metabolism and growth, and a deficiency can affect nail development and health.
It is important to see a board-certified dermatologist or healthcare professional if you notice any dents in your nail beds, as they can be a sign of an underlying health condition. Treatment of the underlying cause can help improve nail health and prevent further complications.

Chronic iron deficiency
Dents in the nail beds can be a sign of chronic iron deficiency, also known as spoon nails. Spoon nails are characterised by flattened nails with deep indentations that can hold a drop of water. The central portion of the nail becomes depressed as it grows, while the rest of the nail appears elevated. Nails may also feel brittle and thin and soft to the touch. Spoon nails are considered to be a manifestation of something deeper in the body.
If you notice dents in your nails, it is recommended to consult a board-certified dermatologist for a diagnosis and treatment. Treatment can help prevent the condition from worsening and improve overall comfort.
To address chronic iron deficiency, it is important to identify and treat the underlying cause. This may involve dietary changes, supplements, or medical intervention, depending on the specific cause. Maintaining a balanced diet rich in iron-containing foods, such as red meat, poultry, fish, beans, and dark green leafy vegetables, can help prevent iron deficiency.
