Can a Nail Grow Under Another Nail?

Can a Nail Grow Under Another Nail?

Yes. Sometimes conditions such as infections, trauma, or tight-fitting shoes can cause a nail to grow under another nail. The infections are usually of fungal origin such as Toenail fungus. It usually occurs in the big toenails.

If you have a nail that has had its growth interrupted by infection or severe trauma, it may detach from the nail bed, and the nail could theoretically resume growth “under” the detached nail. However, there would most likely be pus or other gross stuff under the detached nail, so it should be removed and the regrowing nail allowed to continue growing.

As the new nail grows, it will separate the old nail from the nail bed. This will detach the old nail from proximal to distal without causing discomfort. The old nail may not detach completely; it may separate in most regions but stay partially linked to the nail bed in others. You’ll need to clip as much of the old nail as you can until the separation is complete so you can put your socks on and off. After a good soak in warm water, it’s much easier to remove old nails.

On the other hand, our fingernails develop three times as quickly as our toenails. Fingernails take approximately 6 months to grow back completely.

Fingernails grow at a pace of 3.5 or 3.6 mm per month on average, while toenails grow at 1.6 or 1.7 mm per month on average (avg). However, this can vary depending on our age and diet.

Conclusion

A nail (usually a toenail) can grow under another nail. It is usually caused by infections, trauma, or by wearing tight-fitting shoes for long. The new nail will separate the old nail from the nail bed as it grows. This will eventually detach the old nail from the toe with causing discomfort.

The big toenail take maximum of 18 months to grow back completely while fingernail takes about 6 months. Always keep the affected toe or finger clean to enable the nail grow properly.
