A Comprehensive Approach to Clearing Toenail Fungus
Evidence-based care for stubborn fungal nail infections
Toenail fungus, known medically as onychomycosis, is a common and persistent infection that affects millions of people. It often begins as a small white or yellow-brown spot under the tip of the toenail. As the infection spreads deeper, the nail can become discoloured, thickened and crumbly at the edges. Although it is rarely urgent in its early stages, toenail fungus can be uncomfortable, embarrassing and difficult to treat without the right approach.
Common Signs and Symptoms of Toenail Fungus
How do you know if you have a fungal nail infection? Watch for these common signs:
- Discolouration: Nails turning white, yellow, brown or, in some cases, greenish-black.
- Brittle texture: Nails that feel dry, crumbly or ragged at the edges.
- Thickening: Nails that become unusually thick, hard or difficult to trim.
- Distortion: A nail that has lost its normal shape or is lifting away from the nail bed.
- Odour: A mild, unpleasant smell coming from the affected toe.
What Causes Toenail Fungus and Who Is at Risk?
Toenail fungus is usually caused by dermatophytes, fungi that thrive in warm, moist environments. Anyone can develop a fungal nail infection, but your risk is higher if you:
- Walk barefoot around public pools, gym locker rooms or communal showers
- Have sweaty feet or wear tight, non-breathable shoes for long periods
- Have athlete’s foot or a minor injury to the skin or nail
- Have diabetes, poor circulation or a weakened immune system
Effective Toenail Fungus Treatment Options
Because toenails grow slowly, clearing a fungal infection takes patience and consistency. Depending on the severity of the infection, your chiropodist may recommend one or a combination of the following:
- Topical treatments: Medicated nail lacquers, creams and antifungal solutions for mild or early infections.
- Prescription medications: Stronger antifungal treatments, prescribed when appropriate, to help a new, healthy nail grow in.
- Lunula Laser therapy: A pain-free, in-clinic treatment that uses specific wavelengths of light to target the fungus without harming the surrounding skin.
- Professional nail care: Thinning and debridement of thickened nails to improve comfort and help topical treatments penetrate.
- Home remedies: Options such as tea tree oil or vinegar soaks are sometimes used alongside professional care, but evidence for their effectiveness is limited.
Prevention Tips to Keep Your Feet Healthy
Preventing toenail fungus is much easier than treating it. Protect your feet with these simple habits:
- Keep your feet clean and dry, especially between the toes.
- Wear breathable socks, such as moisture-wicking merino wool or cotton, and change them daily.
- Wear shower shoes or sandals in public locker rooms, pools and gyms.
- Trim your toenails straight across and disinfect your clippers after every use.
- Choose properly fitting shoes that give your toes room to breathe.

Frequently Asked Questions
Toenail fungus is usually caused by dermatophytes, fungi that thrive in warm, damp environments. They enter the nail through tiny cracks in the skin or the small gap between the nail and the nail bed. Common sources include walking barefoot in gym locker rooms, communal showers and pool areas, and wearing sweaty, enclosed shoes for long periods.
Yes. It can spread through direct contact or by sharing personal items such as nail clippers, socks or towels. It can also spread from one toe to another, or from a skin infection such as athlete’s foot.
The infection often starts with a small white, yellow or brownish spot beneath the tip of the nail. As it progresses, the nail may thicken, become brittle or crumbly, lose its shine, change shape or lift away from the nail bed.
Rarely. Without treatment, the fungus usually spreads, making nails thicker, more distorted and sometimes painful in shoes or when walking.
Treatment requires patience, because a healthy new nail must grow out from the base. Since toenails grow slowly, visible improvement usually takes several months, and full results can take 12 to 18 months.
Fungi are common in the environment, so reinfection is possible. Following the prevention tips above, such as keeping feet dry, wearing breathable footwear and wearing sandals in public wet areas, greatly reduces the risk.
No. Lunula is a non-thermal, low-level laser, so most patients feel nothing during treatment. There is no anaesthetic and no downtime, and you can walk normally right after your session.
Lunula Laser can be a good option for people who cannot take oral antifungal medication, have not responded to topical treatments or prefer a drug-free approach. Your chiropodist will assess your nails to recommend the best plan.
Chiropody assessments and treatments are often covered under extended health benefits. Laser treatment coverage varies by plan, so check with your provider. We provide receipts for submission.
