How Do You Treat Thick Curved Toenails?

Thick curved toenails, a condition medically referred to as onychomycosis or ingrown toenails, can be a source of discomfort, pain, and embarrassment. These toenails, often characterized by their abnormal thickness and curvature, can make even the simplest activities like wearing shoes or walking a painful ordeal.

Fortunately, there are various treatment options available to address this condition, ranging from at-home remedies to professional medical interventions. In this comprehensive guide, we will explore the causes of thick curved toenails, preventive measures, and effective treatments to help you regain healthy and comfortable feet.

Understanding The Causes of Thick Curved Toenails

Before diving into the treatment options, it’s crucial to understand the common causes of thick curved toenails. By identifying the root cause, you can make informed decisions about the most suitable treatment approach. Here are some common factors contributing to this condition:

  • Fungal Infections (Onychomycosis): Fungi, like dermatophytes and yeasts, can infect toenails, causing them to thicken, discolour, and become curved. Fungal nail infections are a prevalent cause of thick curved toenails and often result from poor foot hygiene, wearing tight shoes, or walking barefoot in damp environments.
  • Ingrown Toenails: When the edge of a toenail grows into the surrounding skin instead of over it, it can lead to ingrown toenails. This condition can cause pain, inflammation, and thickening of the nail as the body responds to the irritation.
  • Trauma: Injury to the toenail, such as dropping a heavy object on it or stubbing the toe, can damage the nail matrix, leading to abnormal nail growth. This may result in thickened and curved toenails.
  • Age: As individuals age, their nails may naturally thicken and become more curved due to changes in blood circulation and the growth rate of nails.
  • Genetics: Some people are genetically predisposed to have thicker nails, which can be further exacerbated by other factors like fungal infections or trauma.

Preventive Measures For Thick-Curved Toenails

Prevention is often the best course of action when it comes to maintaining healthy toenails. By following these preventive measures, you can reduce the risk of developing thick curved toenails:

  • Maintain Proper Foot Hygiene: Regularly clean your feet and toenails, ensuring you dry them thoroughly, especially in between the toes. Keeping your feet clean and dry helps prevent fungal infections.
  • Trim Nails Correctly: Trim your toenails straight across and avoid cutting them too short or rounding the corners. This reduces the likelihood of ingrown toenails.
  • Choose Comfortable Footwear: Opt for well-fitting shoes that provide ample room for your toes to move. Tight or ill-fitting shoes can put pressure on the toenails and lead to curvature.
  • Protect Your Toes: Wear protective footwear in situations where your toenails may be at risk of injury, such as during sports or manual labour.
  • Practice Safe Nail Care: Avoid using sharp objects to clean under your nails, as this can damage the nail bed and lead to thickening. Instead, use a soft nail brush and mild soap.
  • Manage Fungal Infections: If you suspect a fungal infection, seek treatment promptly to prevent it from spreading to the toenails. Over-the-counter antifungal creams can be effective for mild cases, but more severe infections may require prescription medications.

Treatment Options For Thick Curved Toenails

When preventive measures are not enough or when you’re already dealing with thick curved toenails, it’s essential to explore treatment options. The approach you choose may depend on the underlying cause of your condition. Here are some effective treatments for thick curved toenails:

Topical Antifungal Medications: 

If your thick curved toenails are caused by a fungal infection, topical antifungal creams or nail lacquers can be effective. These medications should be applied as directed by a healthcare professional, and it may take several months to see significant improvement.

Oral Antifungal Medications: 

In cases of severe or persistent fungal nail infections, oral antifungal medications may be prescribed by a doctor. These medications work from the inside out, targeting the fungus responsible for the infection. It’s important to follow the prescribed regimen and be aware of potential side effects.

Surgical Nail Removal: 

In some instances, especially when the nail is severely ingrown or infected, surgical nail removal may be necessary. This procedure involves the partial or complete removal of the affected toenail. Afterwards, a new nail will gradually grow in its place.

Laser Therapy: 

Laser treatment has emerged as an effective option for fungal nail infections. It works by targeting and destroying the fungus that has infected the nail, allowing a healthy nail to grow in its place. Laser therapy is a non-invasive and relatively painless procedure.

Orthopedic Devices: 

To address ingrown toenails, orthopedic devices such as toenail braces or splints can be used. These devices help guide the toenail to grow in the correct direction and can be especially useful in preventing recurrence.

Home Remedies: 

Some individuals find relief from thick curved toenails by trying home remedies like soaking their feet in warm water with Epsom salt, applying tea tree oil, or using over-the-counter cushioning pads to relieve pressure. While these remedies may provide temporary relief, they are not a substitute for professional treatment.

Custom Orthotics: 

If the curvature of your toenails is due to an underlying structural issue, custom-made orthotics or shoe inserts may help correct your gait and reduce pressure on the toenails.

Professional Foot Care: Regular visits to a podiatrist or foot care specialist can help monitor and manage thick curved toenails. These professionals can trim and thin the nails, reducing discomfort and the risk of complications.


Thick curved toenails can be a bothersome and sometimes painful condition, but with the right approach, they can be effectively treated and prevented. Whether your toenails have thickened due to a fungal infection, trauma, or genetics, there are numerous treatment options available. Remember to consult with a healthcare professional for a proper diagnosis and personalized treatment plan.

In addition, adopting good foot hygiene practices and preventive measures can go a long way in keeping your toenails healthy and free from curvature. By taking proactive steps and seeking appropriate care, you can enjoy the comfort and confidence of healthy toenails once again.
