White marks on toenails, commonly known as leukonychia, often appear as white dots, lines, or patches. They can affect one or multiple nails and may result from different causes ranging from injury to health deficiencies. Although they are generally harmless, understanding their cause can help determine if treatment is necessary.
What Causes White Marks on Toenails?
There are several possible causes of white marks on toenails, including:
1. Injuries
Trauma to the toenail, such as stubbing or dropping something heavy on it, is a common cause of white spots. Even minor injuries can disrupt the nail matrix, leading to white spots as the nail grows.
2. Nutritional Deficiencies
Deficiencies in certain vitamins and minerals, such as zinc and calcium, may lead to white spots on toenails. This is especially common in individuals with a poor diet or who have trouble absorbing nutrients.
Certain nail products like polish, acrylic nails, or nail hardeners may cause an allergic reaction, leading to white spots on the toenails.
5. Genetics
Some individuals have a genetic predisposition to white spots on their nails, making them more likely to develop leukonychia regardless of external factors.
6. Other Causes
Systemic Illnesses: Certain systemic diseases like liver or kidney disease may cause leukonychia.
Medications: Side effects of medications, including chemotherapy drugs, can sometimes lead to white patches on toenails.
Types of White Spots on Toenails
Different types of leukonychia present in unique ways:
Punctate Leukonychia: Small, pin-sized white spots scattered across the nail, commonly caused by minor trauma.
Longitudinal Leukonychia: This form appears as white lines running vertically on the nail and may be linked to genetic factors or systemic health issues.
Symptoms and Appearance
White spots on toenails can vary in size, shape, and position. They may appear as tiny dots, larger patches, or thin lines and are typically painless unless linked to an injury or infection.
Diagnosis
If white spots persist or spread, it’s a good idea to consult a podiatrist. They may perform tests like nail scrapings to rule out fungal infections or blood tests to check for deficiencies.
Are White Spots on Toenails a Sign of a Health Issue?
While white spots are often harmless, they can sometimes indicate underlying health issues, especially if they appear suddenly or are accompanied by other symptoms. Chronic white patches or changes in nail thickness might signal a fungal infection, while multiple nails with white spots could point to a nutritional deficiency.
How to Treat White Spots on Toenails
1. Home Remedies
Garlic: Known for its antifungal properties, rubbing garlic paste on the affected nails may help reduce fungal infections.
Apple Cider Vinegar Soak: Soaking nails in apple cider vinegar mixed with water can help prevent fungal growth.
Coconut Oil: Applying coconut oil may help with minor infections due to its natural antifungal properties.
2. Medical Treatments
Antifungal Creams: Over-the-counter antifungal creams or prescription treatments may be necessary for fungal infections.
Topical or Oral Medications: In more severe cases, podiatrists may prescribe medications to treat infections or address deficiencies.
Nutritional Deficiency and White Marks
A balanced diet rich in vitamins and minerals, especially calcium and zinc, is essential for nail health. Foods like leafy greens, nuts, seeds, and dairy products can help improve nail quality.
How to Remove White Spots from Toenails
White spots often fade as the nail grows. Regular trimming and filing can help. Avoid picking at or peeling the nail, as this can lead to infections or worsen the appearance of white spots.

Preventing White Spots on Toenails
To avoid white spots, keep nails trimmed, avoid nail injuries, and moisturize regularly. Limit the use of harsh nail products, and maintain a balanced diet to support nail health.
