Addressing a fungal nail infection is a common medical concern that often leads to questions about the necessity of invasive procedures versus topical applications. While the prospect of nail removal can be daunting, modern management strategies in the United Kingdom typically prioritise non-invasive methods, reserving physical removal for specific and more complex clinical scenarios.

Does treating a fungal nail require removing the nail or will creams work?
Treating a fungal nail infection rarely requires the complete removal of the nail, as topical lacquers and creams can often manage mild to moderate cases by protecting the new growth as it emerges. However, if the infection is exceptionally deep, painful, or has caused significant thickening that does not respond to topical products, a healthcare professional may recommend either chemical softening to remove part of the nail or a minor surgical procedure to remove the nail plate entirely.
How Topical Treatments Interact with the Nail
For most early-stage fungal infections, topical applications such as lacquers and solutions are the first line of management. These products contain active antifungal ingredients that are formulated to penetrate the dense layers of keratin that make up the nail plate. Unlike standard skin creams, which are often too thick to seep into the nail, medical lacquers create a film on the surface that slowly releases medication into the underlying nail bed.
The success of these creams and lacquers depends on the infection being relatively superficial. If the fungus is limited to the top or the edges of the nail, consistent application can effectively clear the organism. Fungal nail infections can often be managed with antifungal treatments available from a pharmacist or GP, provided the infection has not reached the base of the nail.
The Challenge of Thickened Nails
One reason why creams might appear ineffective is the physical barrier of a thickened nail. When a fungal infection is long standing, the nail plate can become exceptionally dense and hard, making it nearly impossible for any topical liquid to reach the fungi living underneath. In these instances, the cream is not failing because of its ingredients, but because it simply cannot reach the site of the infection.
To improve the effectiveness of topicals, a podiatrist might use specialised tools to thin the nail plate through a process called debridement. By reducing the thickness of the nail, the medication can reach the nail bed more easily. This combined approach often prevents the need for full removal while allowing the medication to work more efficiently.
Chemical Nail Removal
When a nail is too thick for creams but surgical removal is not desired, a chemical removal method may be used. This involves applying a high concentration urea paste to the infected nail, which is then covered with a dressing for several days. This paste specifically softens the damaged and infected parts of the nail while leaving the healthy tissue intact.
After the softening period, the diseased part of the nail can be gently scraped away by a healthcare professional. This is a painless process that allows for a concentrated application of antifungal medication directly onto the exposed nail bed. Chemical removal is a non-surgical option that can be highly effective for managing severe nail thickening before beginning a new course of topical care.
When Surgical Removal is Necessary
Surgical removal of the nail, known as a total nail avulsion, is generally reserved for cases where the infection is causing severe pain, recurring bacterial issues, or if multiple other management strategies have failed. This is a minor procedure carried out under a local anaesthetic, where the entire nail plate is removed.
Removing the nail allows for the direct treatment of the underlying skin and ensures that the fungus is physically cleared from the area. While it takes several months for a new nail to grow back, this method provides a fresh start for the nail unit. It is particularly useful for individuals who have a single, very troublesome nail that has become a source of chronic discomfort or mobility issues.
Comparing Recovery and Timelines
The recovery timeline for topical creams is long, often requiring six to twelve months of daily or weekly application as the nail grows out. During this time, the infected portion of the nail remains visible until it reaches the tip to be trimmed away. There is no downtime associated with this method, and it is easily incorporated into a daily routine.
In contrast, the recovery from nail removal is faster in terms of clearing the infection, but it involves a healing period for the skin of the nail bed. Once a nail is removed, the area must be kept clean and dressed for a few weeks until the skin toughens up. While the initial healing is quick, the wait for a full new nail to reappear is still subject to the natural growth rate of approximately one millimetre per month for toenails.
Making the Right Choice with Professional Advice
Choosing between continuing with creams or opting for removal is a decision that should be made after a clinical assessment. A GP or podiatrist can evaluate the severity of the infection and determine if the nail plate is too damaged to be saved. They will also consider your general health, as certain conditions might make one approach safer or more effective than the other.
Conclusion
Treating a fungal nail infection usually involves the use of topical creams and lacquers rather than full nail removal. While removal is an option for severe or painful cases, most people can achieve clear nails through consistent care and patience. Understanding the limitations of creams on thickened nails can help in seeking the right professional assistance to ensure management is successful. If you experience severe, sudden, or worsening symptoms, call 999 immediately.
Is nail removal painful?
Surgical removal is performed under local anaesthetic, so you will not feel pain during the procedure, although the area may be tender for a few days afterward.
Why did my cream not work after six months?
This could be because the nail was too thick for the medication to penetrate or the infection had already reached the nail matrix at the base.
Will my nail grow back normally after it is removed?
In most cases, a new nail will grow back normally over several months, provided the nail bed is kept healthy and free of reinfection.
Can I use a cream after my nail has been removed?
Yes, healthcare professionals often recommend applying antifungal cream to the healing nail bed to ensure any remaining fungal spores are eliminated.
How long do I have to keep a dressing on after nail removal?
You will typically need to keep the area covered and dry for one to two weeks, following the specific aftercare instructions provided by your clinician.
Can I remove the infected part of my nail myself?
It is not safe to attempt to remove part of a nail at home; this should only be done by a professional using sterile equipment to prevent injury or infection.
Do creams work better on fingernails than toenails?
Creams often show results faster on fingernails because the nail is thinner and grows more quickly, allowing the medication to reach the infection more easily.
