Toe nails can take 12 to 18 months to grow back, while finger nails take six months to grow back, according to Web MD. Surgical nail removal is typically done to treat severe or returning fungal nail infections.
When a toenail is surgically removed, it is best to keep the wound clean and dry to prevent infection and promote healthy growth. Using an antibiotic ointment and changing bandages often can assist in the healing process, which often takes a few weeks. Having a toenail removed is painful and comes with risks, such as infection and abnormal nail growth, which can look odd or unhealthy.
