White marks on nails, also known as leukonychia, are usually harmless
In addition to injury, several other factors can cause white spots on nails. One potential cause is an allergy to nail polish, gloss, hardener, or nail polish remover. The chemicals used in the application and removal of acrylic or gel nails can also damage the nails and lead to the appearance of white spots. A common nail fungus called white superficial onychomycosis can also cause white spots on the nails. This fungus can spread to the nail bed, causing the nails to become thick and brittle.
While rare, white spots on nails can sometimes be a symptom of a more serious condition. For example, they may indicate low iron levels, kidney disease, or scarring of the liver (cirrhosis). Additionally, certain hereditary conditions, such as Bart-Pumphrey syndrome and Darier disease, may cause white spots to appear on the nails. If you are concerned about the appearance of white spots on your nails or if they are accompanied by other symptoms, it is recommended to consult a doctor or dermatologist for further evaluation.
It is important to note that the presence of white spots on nails due to injury will usually grow out over time. However, if the spots are persistent, worsening, or accompanied by other symptoms, it is advisable to seek medical advice. A healthcare provider may recommend a biopsy or a fungal culture to help diagnose the underlying cause and determine the appropriate treatment.

They are often caused by trauma to the nail, such as biting or picking
White spots on your nails are usually the result of a nail injury called leukonychia. These injuries can occur due to trauma to the nail matrix, such as biting or picking. They can also be caused by accidentally closing your finger in a car door or striking the tip of your finger with a hammer.
In addition to leukonychia, white spots on your nails can be caused by an allergy to nail polish, gloss, hardener, or nail polish remover. Chemicals used in the application and removal of acrylic or gel nails can also damage your nails and cause these spots. A common nail fungus called white superficial onychomycosis can also appear on your toenails, with the first sign of the infection being a few small white dots. Toenails may appear white and flaky at first and then become thick and brittle.
White spots on the nails caused by trauma usually disappear on their own as the nail grows naturally. Depending on the location of the spot, this can take from a few weeks to several months. If the white spot has appeared close to the base of the nail, it may take about six months or longer for it to disappear, as the whole nail needs to grow back. If the spot is closer to the end of the nail, you will get rid of it quicker.
While white spots on your nails are common and usually do not indicate a serious problem, they can sometimes be a symptom of a more serious condition. These include low iron levels, kidney disease, or scarring of the liver (cirrhosis). If you are concerned about the appearance of your nails, it is recommended to consult a doctor or a dermatologist.

They can also be caused by a fungal infection, which can be treated with medication
White marks on the nails, known as leukonychia, are usually harmless and are often the result of a nail injury. However, in rare cases, they can indicate a more serious underlying condition. One such condition is a fungal infection, which can cause a white film to form on the nails. This is typically characterised by small white dots that may appear on one or more nails. If left untreated, the infection can spread to the nail bed, causing the nails to become thick, brittle, and flaky.
Fungal nail infections can be persistent and challenging to treat. If you suspect you have a fungal nail infection, it is recommended that you consult a healthcare professional for a proper diagnosis and treatment plan. Your doctor may suggest sending nail clippings for laboratory testing to confirm the presence of fungi. This is known as a potassium hydroxide (KOH) preparation or fungal culture.
Once a fungal infection is confirmed, your healthcare provider will recommend an appropriate treatment option. Oral antifungal medications are often prescribed, which may include liquid medicines or pills such as terbinafine (Lamisil®), itraconazole (Sporanox®), or fluconazole (Diflucan®). These medications work internally to combat the fungal infection. It is crucial to complete the full course of oral medication to ensure the fungus does not return and become more resistant to treatment.
In addition to oral medication, topical antifungal treatments can be applied directly to the affected nails. Topical medications typically come in the form of creams, ointments, or gels. While these treatments are applied directly to the nails, it is still important to use them consistently and as directed by your healthcare provider. Proper and consistent use of both oral and topical medications is essential to effectively treat fungal nail infections and prevent recurrence.

In rare cases, white marks can indicate more serious conditions, such as kidney disease or liver cirrhosis
White marks on nails, also known as leukonychia, are usually harmless and are often the result of a nail injury. However, in rare cases, they can indicate more serious underlying health conditions, such as kidney disease or liver cirrhosis.
Kidney disease can cause various nail abnormalities, including changes in colour, texture, and shape. One of the most notable signs is the development of "half-and-half nails" or "Lindsay's nails," where the bottom half of the nail appears white, and the top half is discoloured in pink, red, or brown. This condition is believed to be related to anaemia and increased melanin production due to elevated urea levels in the blood. Additionally, kidney disease can lead to the appearance of white streaks or pale bands, known as Muehrcke's nails, which indicate restricted blood flow in the nail bed.
Chronic kidney disease may also manifest as yellow discolouration of the nails due to nitrogen waste accumulation in the blood. In some cases, kidney disease can cause the nails to become concave or spoon-shaped, brittle, or detached from the skin, indicating chronic renal failure. These nail changes are a result of the body's difficulty in eliminating waste products when the kidneys are not functioning properly.
Liver cirrhosis, on the other hand, can cause a range of nail changes, including Terry's nails, dystrophic nails, onychorrhexis, and onycholysis. These nail abnormalities may be related to changes in nail bed vascularity and the overgrowth of connective tissue.
While rare, the presence of persistent white marks on nails accompanied by other symptoms may warrant further investigation by a healthcare professional to rule out or address any underlying health conditions.

If you are concerned about white marks on your nails, consult a doctor or dermatologist
White spots on your nails are usually nothing to worry about and will often disappear on their own as your nail grows. This process can take anywhere from a few weeks to several months, depending on the location of the spot. If the white spot is close to the base of the nail, it may take about six months or longer to disappear, whereas a spot closer to the end of the nail will disappear much quicker.
These spots are called leukonychia and are usually caused by minor trauma, such as a rough manicure, excessive tapping of the hands on a hard surface, or even accidentally closing your finger in a car door. They can also be caused by a fungal infection, an allergy to nail polish or nail polish remover, or a dietary deficiency.
However, in rare cases, white spots on your nails can indicate a more serious underlying condition. These include low iron levels, kidney disease, or scarring of the liver (cirrhosis). If you are concerned that your white nail spots may be related to a more serious condition, or if they are persistent or worsening, it is important to consult a doctor or dermatologist. They may recommend a biopsy or fungal culture to help make a diagnosis.
If your white nail spots are due to injuries, you can simply wait for them to grow out and then cut them off. However, if they are caused by a fungal infection, your doctor may prescribe oral or topical antifungal medication.
