A yellow, thick, or crumbling toenail usually will not clear up on its own, and drugstore polishes rarely reach the fungus living under the nail. At Skylake Medical Associates in North Miami Beach, our board-certified foot and ankle surgeon diagnoses toenail fungus the right way and builds a fungal nail treatment plan that fits your nail, whether that means prescription antifungals or in-office laser toenail fungus treatment. If you have been searching for a toenail fungus doctor near me in Miami, start here.
Toenail fungus, also written toe nail fungus and known medically as onychomycosis, is a nail infection caused most often by dermatophytes, the same group of fungi behind athlete’s foot. The fungus slips in through a tiny split between the nail and the nail bed, then feeds on keratin and spreads under the nail plate. Because it lives inside and beneath the nail, a surface polish or cream often cannot reach it. That is why nail fungus tends to get slowly worse, not better, when it is left alone or treated only from the outside.
Early on, an early-stage infection may be just a small white or yellow spot under the tip of the nail, often on the big toe. As it grows, the nail changes. Watch for:
Discoloration — a yellow, brown, white, or black toenail fungus stain that deepens over time.
Thickening — the nail turns hard and difficult to trim.
Brittle, crumbly edges — the nail flakes, splits, or breaks apart.
Lifting and debris — the nail separates from the bed, with buildup underneath.
Odor and mild discomfort in shoes as the nail deforms.
There is more than one type of toenail fungus.
The most common is distal subungual onychomycosis, which starts at the front edge and works back toward the cuticle.
White superficial onychomycosis shows up as chalky white patches on top of the nail.
A dark or black fungus nail can look alarming, but color alone does not confirm the cause. A blackened nail can also be a bruise under the nail from a stubbed toe or runner’s toe, so runner’s toe and true fungus are worth telling apart before you treat anything.
Fungi love warm, damp, dark places. Feet give them all three.
You raise your risk when the fungus has an easy way in or a reason to stay:
An easy way in
A reason to stay
Not every discolored or damaged nail is fungal.
Psoriasis, an old injury, and a simple bruise can all mimic it. Treating the wrong thing wastes months, especially with oral medication. So the first visit starts with a real diagnosis: our podiatrist examines the nail and, when it helps, sends a nail clipping or nail culture to confirm the fungus and identify it. That one step tells us whether a topical, an oral antifungal, or laser nail fungus treatment gives you the best odds, instead of guessing. It is also how we separate a true infection from runner’s toe and other look-alikes.
Book a toenail fungus evaluationThere is no single cure that suits every nail. We match the toenail fungus treatment to how much of the nail is involved, how thick it is, and your health history. Most plans use one or more of these:
Thinning and trimming the infected nail eases pressure, clears debris, and helps any medication or laser reach the nail bed.
Prescription-strength lacquers and solutions work best for mild, early infections and for keeping fungus from coming back.
A pill such as terbinafine treats the nail from the inside as it grows out. It clears stubborn cases well, but it takes months and calls for a quick check of your health and medications first.
Laser energy passes through the nail to target the fungus underneath, with no pills and no daily routine. It is a strong option for patients who cannot take oral medication or want to avoid it.
How laser treatment works
For a badly damaged or painful nail, removing part or all of the nail lets a treated nail grow back cleaner. This is reserved for severe cases.
Topical, oral, and laser care are not rivals.
They often work best together, and the right mix depends on the nail in front of us. Because Skylake Medical Associates is a full foot-and-ankle practice, the same doctor can prescribe, perform a procedure, or adjust the plan without sending you elsewhere.
Patients ask about the laser option most, so here is the plain version. Laser fungus removal uses focused light that passes through the nail and heats the fungus in the nail bed, while the nail and the skin around it stay unharmed. There are no injections and no systemic drugs, most people feel only warmth, and you walk out and back to your day right away. Patients also ask about specific devices such as the Lunula laser; the laser we use for nail fungus is the REMY Class IV.
An antifungal laser gives you a way to treat the nail without oral medication. This kind of laser treatment for nails suits people who:
Dr. Sandler confirms the nail change is fungal, not a bruise, psoriasis, or another nail problem.
We trim and thin the affected nails. This helps the laser light reach the nail bed where the fungus lives.
The handpiece moves over each nail. Most people feel warmth and nothing more. There is no anesthesia and no downtime, so you walk out and get on with your day.
Here is the honest part about timing: the laser weakens the fungus now, but the nail you see is already grown. A healthy nail grows out slowly, so it can take several months, sometimes six to twelve, before the clear nail fully replaces the damaged one. A course usually takes more than one session.
| Option | Where it works | What to expect |
|---|---|---|
 Topical
| From the surface | Topical treatments are easy to start and low-risk, but they struggle to reach fungus deep under the nail, so mild cases do best with them. |
 Oral antifungals
| Through the whole body | Oral antifungals can work well, yet they run for months and may call for blood tests to watch the liver, which rules them out for some patients. |
 Laser
| Through the nail | A fungus laser reaches the fungus the creams miss, uses no drugs, and carries few side effects. That is why laser therapy for fungal infections often makes sense when other routes have stalled or are off the table. |
For tougher cases, we pair the laser with a topical and regular nail care. It is a plan, not a one-and-done gimmick.
Straight answer: laser helps many patients, and it is not magic.
In its favor
It is appealing because it skips oral medication and its side effects, and it can be paired with a topical to protect the new nail.
Keep in mind
It is not instant, results vary from nail to nail, fungus can return if the conditions that fed it stay the same, and it is often treated as cosmetic by insurers.
What moves the odds in your favor:
The same REMY laser is also used for nerve pain and other foot conditions; read more on our REMY laser treatment page. At your visit we will tell you honestly whether laser, medication, or a combination fits your nail best.
See a nail fungus doctor if the nail is spreading, thickening, or hurting, if it keeps coming back after drugstore products, or if more than one nail is involved.
Come in sooner if you have diabetes, poor circulation, or a weakened immune system, because a small nail infection can turn into a bigger problem for the whole foot.
Early care is simpler, cheaper, and far more likely to save the nail than waiting a year to see what happens.
