Treatments At Our Clinic

There are many types of treatments for Onychomycosis from topical over the counter remedies to prescription medications, laser treatments and surgeries. In general, over the counter and topical prescription medications have a very low success rate unless the infection is treated almost immediately from its inception. Oral antifungal medication is somewhat more effective and could take up to three to six months for their desired effect. Some of these medications can have secondary effects and, in some instances, may require monthly blood tests. These tests are to verify that the medication is not causing any ill effects on the liver. Thermal and cold laser therapies are also an option and may take as long as three months or more to attain their desired effects. 

  • Usually at the beginning of the infection we notice small changes in the nails: 
  • Discoloration (Nails that are yellow, white, or darker than normal) 
  • Thickening of the nail (Nail plate thickens and is harder to cut) 
  • White lines, Striations, or fissures in the nail 
  • A bad odor comes from the nails especially when the foot is humid 
  • Debris under the nail usually white or yellow in color

Onychomycose (Fungus on toenails) is a very common problem among the population in North America. According to the National Institutes of Health in the United States In North America, the incidence of onychomycosis is up to 14% in the general population, with fungal infection responsible for 50% of all nail disease. Here in Canada the incidence of toenail fungus is up to 20 % of the population.Trichophyton rubrum is most common micro organism in cases of fungal toenail infections. The pathogen is commonly found in public places associated with humid conditions. Such places as public showers, gyms, locker rooms, and pools have a higher incidence of these micro organisms. Fungal infections flourish in warm dark humid environments such as the inside of shoes and boots. Risk factors include diabetes, circulatory or immune system problems as well as excessive sweating. People who have frequent athlete’s foot skin infections are more susceptible to toenail fungal infections.

Nail Fungus Symptoms

In our clinic we possess specialized equipment to effectively trim and remove the thickness of the nail without any pain whatsoever. Patients leave the clinic with satisfaction and relief. These treatments in combination with prescribed topical anti-fungal agents can yield good results. The procedure can be repeated as necessary and is a great option for patients who cannot take certain oral medications due to health problems. In cases of severely deformed or thickened discolored nails it is sometimes necessary to perform a procedure to remove the fungal toenail under local anesthesia.

​A Podiatrist is the foremost expert in this field and should be consulted to discuss the best treatment options for each individual case. It is important to consult as soon as changes start to take place in the nails. In this way effectiveness of treatment increases and duration of treatment decreases. When left untreated onychomycosis can cause permanent damage to your nails. Diabetics should always consult a Podiatrist as soon as any foot problem develops because they are more susceptible to complications from foot afflictions. After a successful treatment for a fungal nail infection it is important to take precautions because recurrence or reinfection is possible.  

At our clinic we offer all modes of treatments for thick fungal toenails from conservative to minimally invasive surgery. Most cases can be resolved in a conservative manner. Timely intervention and treatment prevents fungal toenails from becoming chronic. Our 25 years of experience ensures you will receive the appropriate treatment plan. Wait times for appointments at our clinics are relatively low. We are always happy to welcome new patients into our family foot care practice.

Prevention Of Fungal Toenails

Fungal Toenails & Thick Toenail Treatments

  • Good foot hygiene (Clean feet and drying the feet well after bathing)
  • Choose shoes made out of materials that breathe (synthetic materials and other fabric blends offer more breathability and freer air circulation)
  • Choose socks which limit perspiration (Athletic or wicking socks) 
  • Use antifungal powders in socks and shoes 
  • Avoid nail salons that do not sterilize instruments for each customer 
  • Excessive use of nail polish & removers (acetone) could damage the nail plate and increase the chance for a fungal infection
