Why is My Big Toe Nail White? Causes and Treatments
If you notice that your big toenail is turning white, then you might be concerned, but in reality, they are not a cause for alarm. Understanding the cause of your white toenails is the first step to treating them. In this guide, we’ll run through the causes of white toe nails so that you can put your mind at ease. You’ll also find treatment options and prevention tips for clear, healthy nails.
Common Causes of White Nails
There are several reasons why your toenails might be turning white. Some of the main ones can be found below:
Toenail Fungus
One of the biggest (and most common) causes of toe nail discoloration would be nail fungus. Toenail fungus, or onychomycosis, is a common issue that affects up to 14% of the American population every year. If you suspect that you have this condition, you’ll first notice a yellow or white spot under the nail.
This will eventually spread, causing thick toenails that crumble over time. If you don’t treat the issue with a nail fungus treatment, it will spread to other toes, causing pain and discomfort. There are multiple types of toenail fungus as well, which include:
- Subungual onychomycosis
- White superficial onychomycosis
- Candida onychomycosis.
Toenail Fungus Treatment
The good news is, nail fungus treatment is relatively straightforward and simple (though it can get complicated if left untreated).
A lot of the time, a simple treatment such as a topical antifungal will be enough, but depending on the stage, extra care might be needed.

Leukonychia
Another cause of white toe nails would be leukonychia. If you’re wondering why is my big toe nail white, but doesn’t have any other symptoms, then there’s a high chance that this is the cause. You may notice white spots or streaks on the nails or slight discomfort.
This is usually caused by trauma, such as the pressure from tight shoes or stubbing your toe. A lot of the time, it’s harmless and temporary. If you notice any redness or swelling, however, then this could indicate a possible nail infection as well. There are two types of leukonychia.
- True leukonychia
- Apparent leukonychia.
Leukonychia Treatment
There isn’t any recommended treatment for this condition. Your nail will grow out over time. While you wait for the nail to grow, you can avoid wearing tight shoes or putting pressure on the toenail if you can.
Nail Psoriasis
If you have a skin condition, like psoriasis or eczema, then this can affect the matrix of the nail. This can cause white patches, as well as thick and pitted nails. If you suspect that this is the case, then you need to treat the underlying skin condition. When you do, you will notice that the nail clears up on its own. Symptoms to look out for include:
- Onycholysis
- Pitting
- Discoloration
- subungual hyperkeratosis
Nail Psoriasis Treatment
You can also use topical corticosteroids to help reduce any inflammation around the nail, and you can also try systemic medication. Please keep in mind, really talk to your doctor if you suspect that there is an issue like this; however, as it may be that the psoriasis needs treatment first.
Gingerbread Nail Disease
Gingerbread nails disease can be a sign of liver disease, heart failure, or diabetes. This happens when the nail appears to be white, with a pink or brown band at the top. Symptoms to watch out for include:
- Thickening
- Distortion
- Discoloration
Gingerbread Nail Disease Treatment
Treatment involves first diagnosing the underlying condition. It may be that you need to undergo several medical tests so that you can manage the root cause. Only then will you see an improvement.
Thick Toenails
As you age, your toenails will naturally grow thicker. It may be that they turn yellow or white during this process. Although this is nothing to worry about, you do need to take note of any other medical conditions that could be contributing to this. If you have poor circulation or if you have vascular disease, then this can also impact your nail color and growth.
- Brittle nails
- Thick nails
- Crumbling toe nails
Thick Toenails Treatment
Moisturize and trim your nails regularly. Keep them clean, and visit a podiatrist if you want to prevent ongoing complications, including nail infections.
Preventing Nail Infections
Practicing good hygiene is one of the best ways for you to prevent nail infections. You should also avoid walking barefoot in communal areas and keep your nails trimmed. Wearing breathable footwear and using antifungal sprays, if you are prone to sweaty feet, is also a good step to take.
To further push your nail health, you can also:
- Trim nails straight across and regularly
- Keep feet clean and dry
- Change socks daily; use breathable shoes
- Disinfect nail tools
- Avoid aggressive manicures or pedicures
- Apply antifungal foot powder if prone to sweating
When to Seek Medical Help
If your nails are becoming thick, brittle, or crumbly, then you should see a medical professional. If the nail is swollen, painful, or has discharge, then again, seeing a doctor is the way to go. If you have tried a number of treatments with no success, then this is another big sign that you should see a professional.
Pay attention to:
- Persistent discoloration that doesn’t grow out
- Nail thickening, separation, or foul smell
- Pain, swelling, or pus
- History of diabetes or circulatory issues
- Spreading patches or nail crumbling
FAQs
Is a white toenail always a fungus?
Not always. It can also be caused by trauma, leukonychia, or even polish damage. Fungus is just one possibility.
Can I whiten toenails at home?
You can gently buff surface stains, use whitening toothpaste, or soak feet in diluted hydrogen peroxide or lemon water, but only if it’s not fungal or medical.
What vitamin deficiency causes white nails?
Zinc and calcium deficiencies are often associated with white spots or streaks on nails.
Is it safe to paint over a white toenail?
Not knowing the cause and painting over a white nail can worsen the issue. Avoid covering up white discoloration without knowing the cause. It may trap moisture and worsen fungal infections.
