If part of your toenail looks white, yellow, or detached from the skin underneath, you may be experiencing onycholysis — a condition where the nail separates from the nail bed.
Toenail lifting can occur gradually or after injury. While it may not always be painful at first, the space under the nail can trap moisture and bacteria, increasing the risk of infection.
Our foot clinic provides professional assessment and treatment for toenail trauma and lifting in Toronto to protect the nail and support healthy regrowth.
Onycholysis is the medical term for separation of the nail plate from the nail bed. When this occurs, the detached portion may appear white, yellow, or opaque because air becomes trapped underneath.
Once a nail lifts, it does not reattach. The goal of treatment is to manage the separated area and guide healthy new nail growth.
Common causes include:
Direct injury or trauma to the toe
Repetitive pressure from tight footwear
Running or high-impact activity
Fungal nail infection
Psoriasis or inflammatory skin conditions
Improper nail trimming
In some cases, trauma may be minor and not immediately noticeable.
You may notice:
A portion of the nail turning white or yellow
Visible separation from the skin underneath
Debris collecting beneath the nail
Nail catching on socks or shoes
Mild tenderness or sensitivity
Over time, lifted nails may thicken, discolour, or become infected if not properly managed.
Treatment depends on the cause and extent of separation.
Careful trimming and stabilization of the lifted nail may be performed to prevent further catching or tearing. Managing the detached portion safely helps reduce additional trauma.
Assessment for fungal infection may be recommended when discoloration or thickening is present. Identifying infection early allows for appropriate treatment planning.
Debridement and cleaning beneath the nail may be performed to remove trapped debris and reduce bacterial or fungal buildup.
Monitoring regrowth is important, as a healthy nail must gradually grow forward to replace the separated portion. Regular professional care can help prevent complications during this process.
Consider booking an assessment if:
The lifted area continues to spread
The nail becomes thickened or discoloured
The nail catches easily or feels unstable
There is redness, drainage, or signs of infection
You have diabetes or circulation concerns
Early evaluation helps protect the nail and surrounding tissue.
If your toenail is lifting or separating, a professional assessment can determine the cause and guide appropriate care to support healthy regrowth.
