What causes toenail fungus? Toenail fungus (onychomycosis) is caused by dermatophytes — fungi that thrive in warm, moist environments. Common sources of infection include public pools, locker rooms, nail salons with poorly sterilized tools, and wearing tight, sweaty shoes for extended periods.

What does toenail fungus look like? Fungal nails typically appear yellow, white, or brown and become thickened, brittle, or crumbly. The nail may separate from the nail bed, and a mild odor is sometimes present. The infection usually starts at the tip or edge of the nail and progresses inward.

Is toenail fungus contagious? Yes. Fungal nail infections can spread to other toenails, to the skin (causing athlete’s foot), and to other people through shared surfaces or nail tools. Treating the infection promptly and practicing good hygiene helps prevent spread.

Can toenail fungus go away on its own? No. Fungal nail infections rarely resolve without treatment and typically worsen over time. The fungus penetrates the nail and nail bed, making it difficult for the immune system to eliminate without medical intervention.

What is the most effective treatment for toenail fungus? Treatment depends on the severity of the infection. Options include topical antifungal medications, oral antifungal medications, laser therapy, and nail restoration. Severe or persistent cases often require a combination approach. Dr. Tanwir will assess your nails and recommend the best plan.

How long does it take to treat toenail fungus? Because nails grow slowly, full clearance can take 6 to 12 months even after successful treatment. You will typically see new, healthy nail growth coming in from the base as treatment progresses.

Is laser treatment for toenail fungus effective? Yes. Laser therapy is a safe, effective option that targets the fungus beneath the nail without damaging surrounding tissue. Multiple sessions may be required depending on the severity of the infection. It has no systemic side effects, making it a good option for patients who cannot take oral medications.

Can I get a pedicure if I have toenail fungus? Standard nail salons are not recommended if you have toenail fungus — the risk of spreading the infection to other nails or other clients is high, and salon tools may not be properly sterilized. Our Medical Pedicure service provides safe, clinical nail care in a sterile environment for patients with fungal infections or other nail concerns.

Are fungal nail treatments safe for diabetics? Yes, but diabetic patients should always seek professional treatment rather than using over-the-counter antifungals without guidance. Diabetes affects healing and immune response, so fungal infections in diabetic patients require careful monitoring and professional management.
