White spots on your nails, also known as leukonychia, are usually harmless but may indicate an underlying medical condition. They are a common condition and are usually the result of a nail injury. However, they can also be caused by fungal infections, allergies, mineral deficiencies, or even heavy metal poisoning. In rare cases, white spots on your nails can be a sign of a more serious medical issue, such as liver failure or heart failure. While not always a cause for concern, it is important to be aware of the potential causes and seek medical advice if necessary.

What You'll Learn
White dots on nails are usually harmless
White dots on nails, also known as leukonychia, are usually harmless. They are a common condition and are generally not a cause for concern. Leukonychia can be categorised into three types: true leukonychia, apparent leukonychia, and pseudoleukonychia. True leukonychia occurs when the white spots form at the nail matrix, the beginning edge of the nail located under the skin of your finger just before the visible part of the nail. It appears in the hard part of the nail, called the nail plate. Apparent leukonychia occurs when the white spots form on the skin beneath the nail, called the nail bed, rather than on the nail itself. Pseudoleukonychia is caused by a fungus growing on the outside of the nail, causing the upper layers of the nail plate to become scaly.
The most common cause of white dots on nails is injury or trauma to the nail, which can be prevented with proper nail care. This can include bumping or biting your nails, or getting your nail caught on something. Repeated manicures and pedicures can also cause trauma to the nail, as the tools, polishes, and chemicals used can damage the nail plate or nail bed. In addition, electric files used during manicures can damage the surface of your nail. White dots can also be the result of picking or biting your nails due to anxiety.
Another possible cause of white dots on nails is a fungal infection. This can happen when microbes from the environment enter through small cracks in your nails or the surrounding skin. A common nail fungus is called white superficial onychomycosis, which can appear on your toenails. Antifungal medications are usually prescribed to treat fungal infections.
Allergies to nail products, such as nail polish, gloss, hardener, or nail polish remover, can also cause white dots on nails. Additionally, chemicals used in the application and removal of acrylic or gel nails can damage the nails and lead to the formation of white spots.
In rare cases, white dots on nails can be an indication of a systemic illness, nutritional deficiency, or heavy metal poisoning. For example, low calcium levels may cause white spots on nails, along with dry skin and coarse hair. However, it is important to note that iron deficiency typically does not cause spots, but rather thin nails with raised ridges that curve inward. Certain medications, such as retinoids, antibiotics, and blood pressure medications, have also been linked to white spots on nails.

They are usually caused by injury or trauma
White spots on your nails, also known as leukonychia, are usually harmless but may indicate a medical condition. The most common cause of white spots on the nail is injury or trauma. This can be prevented with proper nail care.
Injury to your nail — like from picking or biting them — can cause white spots to appear. Bending your nail back, hitting your nail on a hard surface, or getting your nail caught on something can also lead to white spots. This is because when injured, the layers of keratin that your nails are made of can crack or have air trapped between them, leading to white spots.
White spots on your nails can also result from repeated manicure and pedicure procedures. Electric files can damage the surface of your nail, and the tools, polishes, and chemicals used during the service can cause spots even without significant injury.
White spots caused by injury or trauma are called leukonychia. True leukonychia occurs when the white spots form at the nail matrix, the beginning edge of the nail located under the skin of your finger just before the visible part of the nail. They appear in the hard part of your nail, called the nail plate. Apparent leukonychia happens when the white spots form on the skin beneath the nail (the nail bed), rather than on the nail itself. This type can be distinguished from true leukonychia because the spots fade when pressure is applied to the nail, and they do not move across the nail as the nail grows.

They can be caused by fungal infections
White spots on your nails are a common condition and are generally harmless. They are usually the result of a nail injury called leukonychia, which occurs when you accidentally bump or bite your nails. However, they may also indicate a fungal infection. Fungal organisms can enter your toenail or fingernail through small cracks in the keratin or the nearby skin and cause an infection. This is known as mycotic nails.
Mycotic nails can be caused by a variety of organisms, including dermatophytes, nondermatophyte molds, yeast, and various species of Epidermophyton, Microsporum, and Trichophyton. These infections can cause your nails to become thick, fragile, and separated from the nail bed, with a brownish, whitish, or blackish discolouration. You may also experience cracks in the keratin of your nail.
Fungal nail infections usually start at the edge of the nail and can spread to the entire nail, making it thicker and turning it white or yellow. In some cases, the nail may become brittle and crumbly. A specific type of fungal infection called superficial white glycomycosis is characterised by white flaking on the top of the fingernail. Another common nail fungus is called white superficial onychomycosis, which can appear on your toenails as a few small white dots that can spread to your nail bed.
It is important to note that fungal infections are contagious and can be passed from person to person. Preventative steps, such as keeping your feet away from others, wearing shoes in communal spaces, and not sharing shower stalls without cleaning them first, can help reduce the spread of fungal infections. If you suspect a fungal infection, it is recommended to consult a healthcare provider for diagnosis and treatment.

They can be a symptom of a medical condition
White spots on your nails, also known as leukonychia, are usually harmless but may indicate an underlying medical condition. While the presence of these spots is most commonly due to injury, it is important to be aware of other potential causes, as they can sometimes signify more serious health issues.
Systemic Diseases
White spots on your nails can be a rare symptom of systemic diseases, which affect the entire body. These include serious conditions such as diabetes, heart failure, HIV, liver cirrhosis, and psoriasis. In the context of systemic diseases, the presence of white spots on your nails may indicate an internal condition, such as liver disease, kidney disease, or heart failure.
Hereditary Conditions
Certain hereditary conditions that affect your nails, such as Bart-Pumphrey syndrome and Darier disease, may also cause white spots to appear. Additionally, true leukonychia, a type of leukonychia that originates in the matrix of the nail, can be an inherited condition, although this is very rare.
Nutritional Deficiencies
Nutritional deficiencies, including mineral deficiencies, have been linked to the development of white spots on nails. Specifically, low levels of calcium, zinc, and iron have been implicated. However, it is important to note that while iron deficiency can cause nail changes, it typically does not result in spots. Instead, nails may become thin, exhibit raised ridges, or curve inward.
Toxic Heavy Metal Exposure
In rare instances, white spots on your nails can indicate exposure to toxic heavy metals, such as thallium, arsenic, or strontium. This exposure can occur through contaminated food consumption or inhalation of industrial fumes. Arsenic poisoning, in particular, has been associated with the development of white bands called Mees' lines across the nails.
Medical Treatments and Medications
Certain medical treatments and medications have been known to cause white spots on nails. For example, individuals undergoing chemotherapy often develop leukonychia striata, characterised by lines that run parallel to the base of the nail. Additionally, specific medications like retinoids, antibiotics, blood pressure medications, and drugs that prevent organ rejection have been implicated.

Answer: White spots on your nails are usually harmless and are generally not a major cause for concern. They often appear after an injury to your nails, like bumping them against a hard surface, getting your nail caught on something, or biting them. In most cases, your white spots will eventually grow out until you can remove them with nail clippers or nail scissors.
However, in some cases, white spots on your nails can be caused by a common nail fungus called white superficial onychomycosis. This can appear on your toenails or fingernails and may first show up as a few small white dots on your nails. If you have a fungal infection, your treatment options may include oral or topical antifungal medications.
Oral Antifungal Medication
Your healthcare provider may prescribe liquid medicines or pills/tablets that you swallow with water. These medications may include terbinafine (Lamisil), itraconazole (Sporanox), and fluconazole (Diflucan). You'll need to take the medication every day for several months or longer. It's important to finish your full course of medicine to avoid the fungus coming back and being harder to treat.
Topical Antifungal Medication
Topical medications usually come in the form of creams, ointments, or gels that you rub directly onto your nails. These are most effective when paired with oral medications. Your healthcare provider may also direct a high-tech laser beam and special lights at your toenail to treat the fungus, although lasers are not a cure and have lower cure rates than oral and topical medications.
