Toenail Fungus Treatment in Brighton, MI

Thick, Yellow, or Brittle Toenails? It May Be Toenail Fungus.

Toenail Fungus, also known as onychomycosis, is one of the most common nail conditions treated by podiatrists. The infection often begins as a small white or yellow spot beneath the edge of the toenail but gradually spreads deeper into the nail. As the fungus grows, the nail may become thickened, discolored, brittle, crumbly, or begin separating from the nail bed.

While many people think toenail fungus is only a cosmetic concern, it can progress if left untreated. The infection may spread to other toenails, involve the surrounding skin, cause discomfort when walking or wearing shoes, permanently damage the nail, and increase the risk of recurrent infections.

At Brighton Foot and Ankle, our providers offer comprehensive evaluation and evidence based treatment for toenail fungus tailored to each patient’s medical condition, medical history, and personal preferences.

Where Does Toenail Fungus Come From?

Toenail fungus develops when microscopic fungi enter the nail through tiny cracks in the nail, cuticle, or surrounding skin. Once beneath the nail, these organisms thrive in the warm, dark, and moist environment created inside shoes and socks. Over time, the infection can spread deeper into the nail, causing discoloration, thickening, brittleness, and separation of the nail from the nail bed.

The most common cause of toenail fungus is a group of fungi called dermatophytes, although certain yeasts and molds can also infect the toenails. In many cases, the infection begins as athlete’s foot (tinea pedis) before gradually spreading underneath one or more toenails.

Toenail fungus is not caused by poor hygiene alone. Even people who regularly care for their feet can develop fungal nail infections after exposure to fungi in public places or from everyday risk factors such as aging, certain medical conditions, or minor nail injuries.

Risk Factors for Toenail Fungus:

You may be more likely to develop toenail fungus if you:

Walk barefoot in public locker rooms, pools, or communal showers
Frequently wear tight or poorly ventilated shoes
Have sweaty feet or spend long periods in damp footwear
Have athlete’s foot
Have diabetes or poor circulation
Have a weakened immune system
Have experienced trauma or injury to the nail
Are over the age of 60
Have a family history of fungal nail infections

What Are the Symptoms of Toenail Fungus?

Toenail fungus often develops gradually. Common signs and symptoms include:

Yellow, white, brown, or even black discoloration
Thickened toenails
Brittle or crumbly nails
Nails that become difficult to trim
Distorted nail shape
Debris underneath the nail
Separation of the nail from the nail bed
Foul odor
Pain or pressure while wearing shoes
Dry, flaky, itchy skin consistent with athlete’s foot

Because several nail disorders look similar, it is important not to assume every thick or discolored nail is fungal.

How Is Toenail Fungus Diagnosed?

Although many fungal infections can be recognized during a physical examination, other conditions including nail trauma, psoriasis, eczema, bacterial infections, and age-related nail thickening, can closely resemble toenail fungus.
For this reason, our providers here at Brighton Foot and Ankle may recommend obtaining a small nail clipping or scraping for laboratory analysis. When needed, a small nail clipping or scraping may be sent to a laboratory to confirm whether a fungal infection is present. Confirming the diagnosis helps ensure the most effective treatment is selected while avoiding unnecessary medications.

Can Toenail Fungus Go Away on Its Own?

Rarely. In most cases, toenail fungus does not go away on its own and typically worsens over time.

Unlike fungal infections that affect only the skin, toenail fungus lives beneath the nail plate and within the nail bed, making it difficult for the body’s immune system and many over-the-counter treatments to completely eliminate the infection. Because toenails grow slowly, the damaged portion of the nail remains in place for months, allowing the fungus to continue growing and spreading.

Without treatment, the infection may:

Spread to additional toenails or the surrounding skin
Cause the nail to become thicker, yellow, brown, or white
Lead to brittle, crumbly, or distorted nails
Cause the nail to separate from the nail bed (onycholysis)
Make walking or wearing shoes uncomfortable in more advanced cases

How Is Toenail Fungus Treated?

Early diagnosis and treatment provide the best opportunity for successful clearance before permanent nail damage occurs. At Brighton Foot and Ankle, we evaluate the severity of the infection and recommend a personalized treatment plan, which may include prescription topical medications, oral antifungal medication, routine nail debridement, or other treatment options depending on your overall health and the extent of the infection.

Treatment depends on the severity of the infection, the number of nails involved, your overall health, and your treatment goals. Our providers will recommend the treatment option, or combination of treatments that offers the greatest chance of success for your specific infection.

Topical Antifungal Medications

Prescription topical antifungal medications are applied directly to the affected nail. These treatments work best for mild to moderate infections and often require several months of consistent use while the nail grows out.

Oral Antifungal Medication

For more extensive infections, oral antifungal medications often provide the highest cure rates by treating the fungus from within the nail while also helping eliminate any associated athlete’s foot (tinea pedis).

Before prescribing oral antifungal medication, routine liver function blood work is obtained. Repeat laboratory testing is performed approximately 30 days after beginning medication to monitor for rare side effects and ensure the medication remains safe.

Nail Debridement

Thick fungal nails create a barrier that prevents medications from reaching the infection. Regular debridement involves carefully thinning and trimming the affected nail, reducing nail thickness and allowing topical medications to better penetrate the infected nail, improving treatment effectiveness.

Urea Cream

Dr. Castelein and Dr. Tinawi frequently recommend combining prescription antifungal medication with a 42% urea cream. Urea is a keratolytic medication that softens and thins thick fungal nails, allowing topical antifungal medications to penetrate deeper into the infected tissue and improve treatment effectiveness.

Can Toenail Fungus Be Permanently Cured?

Yes, many cases of toenail fungus can be successfully treated, especially when diagnosed early and managed with the appropriate treatment plan. However, because the fungi that cause toenail infections are common in the environment, it is possible to develop a new infection even after the original one has been eliminated.

The success of treatment depends on factors such as the severity of the infection, the number of nails involved, your overall health, and following your prescribed treatment. Even after the fungus is gone, it may take 9 to 18 months for a healthy toenail to completely grow out and replace the damaged nail.

To help prevent recurrence, Dr. Castelein and Dr. Tinawi recommend practicing good foot hygiene, treating athlete’s feet promptly, keeping feet clean and dry, disinfecting footwear regularly, and wearing sandals in public locker rooms, pools, and showers. Combining effective treatment with these preventive measures offers the best chance of long-term success and healthy, fungus-free nails.

How Can I Prevent Toenail Fungus From Coming Back?

Preventing reinfection is just as important as treating the original infection. Simple daily habits can significantly reduce your risk of reinfection.

To help prevent toenail fungus:

Dry your feet thoroughly between your toes after bathing
Change socks whenever they become damp or sweaty
Wear breathable shoes with adequate ventilation
Rotate shoes to allow them to dry completely between uses
Spray the inside of shoes weekly with an alcohol-based antifungal spray
Wear sandals in locker rooms, public pools, and communal showers
Trim toenails regularly to keep them clean
Treat athlete’s foot promptly before it spreads to the nails
Avoid sharing nail clippers or footwear with others

Frequently Asked Questions:

Is Toenail Fungus Contagious?

Yes. Toenail fungus can spread from person to person and from one toenail to another. It can also spread through contaminated shoes, socks, showers, locker rooms, and nail care instruments. Toenail fungus can also spread to the skin on the bottom of the foot in a condition called athlete’s foot or tinea pedis.

Is Toenail Fungus Dangerous?

Toenail fungus is usually not dangerous, but it should not be ignored. Without treatment, the infection can spread to other toenails, become painful, permanently damage the nail, and increase the risk of skin infections, especially in people with diabetes, poor circulation, or a weakened immune system.

What Happens If Toenail Fungus Is Left Untreated?

Toenail fungus rarely goes away on its own and typically worsens over time. The nail may become thicker, more discolored, brittle, painful, or separate from the nail bed. Over time, thick, brittle nails may permanently damage the nail matrix (growth center), resulting in lasting nail changes. Early treatment offers the best chance of eliminating the infection before permanent nail damage occurs.

Can Thick Toenails Be Something Other Than Fungus?

Yes. Thick, discolored, or brittle toenails are not always caused by toenail fungus. Nail trauma, psoriasis, aging, and other nail conditions can produce similar changes. At Brighton Foot and Ankle, we perform a thorough evaluation and, when appropriate, laboratory testing to confirm the diagnosis before recommending treatment.

Does My Toenail Need to Be Removed to Treat Toenail Fungus?

In most cases, no. Toenail fungus can often be successfully treated without removing the entire nail. Regular trimming and thinning (debridement) of the affected nail is an important part of treatment because it reduces nail thickness, relieves pressure, and allows prescription medications to better penetrate the infected nail. Complete nail removal is rarely necessary and is typically reserved for severe cases or nails that are causing significant pain or have been extensively damaged by the infection.

Can I Wear Nail Polish if I have Toenail Fungus?

Nail polish can trap moisture and make it difficult to monitor treatment progress. It is generally best to avoid cosmetic nail polish until the infection has improved.

Will vinegar, tea tree oil, or home remedies cure toenail fungus?

While many home remedies are popular online, scientific evidence supporting their effectiveness is limited. Most moderate to severe fungal infections require prescription treatment for the best chance of success.

Do Lasers Help Treat Toenail Fungus?

Laser treatment for toenail fungus may improve the appearance of some infected nails, but current research has not consistently shown it to be as effective as FDA-approved prescription treatments. At Brighton Foot and Ankle, we recommend evidence-based treatment options, including prescription topical medications, oral antifungal therapy when appropriate, and nail debridement, to provide the highest likelihood of successfully treating onychomycosis.

When Should I See a Podiatrist for Toenail Fungus?

You should see a podiatrist if your toenail becomes thick, discolored, brittle, painful, difficult to trim, or if over-the-counter treatments have not worked. Patients with diabetes, poor circulation, or peripheral neuropathy should have any suspected fungal nail infection evaluated promptly to help prevent complications.

How long does fungal nail treatment take?

Because toenails grow slowly, treatment often takes 9 to 18 months before a completely healthy nail has fully grown out. Oral medications help resolve the active fungal infection quickly but even after the fungus has been eliminated, visible improvement occurs gradually as healthy nail growth replaces the damaged nail.

Should every thick toenail be treated with antifungal medication?

No. Thick toenails can result from trauma, psoriasis, aging, or other nail disorders. An accurate diagnosis is important before beginning treatment.
