In extreme cases, the nail may even detach from the nail bed. While various factors can cause such injuries, proper care ensures healing.
Understanding how a nail tears requires knowledge of its structure. Nails, whether on fingers or toes, consist of a nail bed and a nail plate. The nail bed is the soft skin beneath the hard nail plate. Cells in the nail matrix, located at the base of the nail bed, produce keratin, a protein that forms the nail plate and secures it to the nail bed. When a nail tears or separates, the nail matrix regenerates the new nail [source: Mayo Clinic].
There are countless ways to damage your nail plate, but improper trimming is the most frequent cause. Cutting nails at incorrect angles often results in tears or hangnails [source: Bruno]. Additionally, slamming your nail between objects like a door and frame or suffering from conditions like fungal infections can cause the nail plate to detach from the nail bed. Factors such as nail psoriasis, chemical exposure (e.g., acetone), certain medications, or chemotherapy can also make nails more susceptible to breakage [source: Van Houten].
Both nail tears and separations can be painful and slow to heal, as they require time to regrow. However, adopting a few straightforward measures can aid in the recovery process and help prevent future damage. Continue reading to discover effective strategies for healing torn or separated nails.
Treating Torn Nails
The most effective approach to treating a torn nail is allowing it time to regrow naturally. Ensuring safe regrowth and implementing home remedies can alleviate pain and discomfort during the healing process.
Several methods are available for treating a torn nail: You can secure the torn section with tape and trim it as the nail grows, or immediately clip the damaged portion at a slight outward angle to encourage normal regrowth. For minor tears, applying clear nail polish can prevent further splitting, followed by trimming as the nail grows [sources: Aetna InteliHealth, Mayo Clinic, Rouzier].
If your nail plate has completely detached from the nail bed, reattachment isn't possible. You must wait for a new nail to grow. Similar to a torn nail, you can secure the detached nail with tape and trim it as the new nail grows. In some cases, complete removal of the separated nail and bandaging the exposed nail bed may be necessary. Consult a physician to determine the best course of action. If the tear or separation is due to an infection, seek medical treatment. Keeping the nail area dry can help prevent infections [sources: Aetna InteliHealth, Mayo Clinic, Rouzier].
For pain relief in a finger or toe with a torn nail, consider taking an over-the-counter anti-inflammatory medication. If the pain is intense or persistent, consult your doctor [source: Rouzier].

Nail psoriasis, which often accompanies skin psoriasis, can make nails more prone to tearing or separation. This condition weakens nails and may cause discoloration of the nail bed, turning it white, red, or yellow. Treatments such as calcipotriol solution, corticosteroids, and antifungal therapies can help manage nail psoriasis. If you suspect you have this condition, consult your doctor for appropriate treatment options [source: New Zealand Dermatological Society].
Regrowing Nails
Dealing with torn or separated nails can be challenging. Nails grow at a rate of approximately 0.004 inches (0.1 millimeters) daily, meaning it can take up to six months for a nail to fully regenerate [source: Mayo Clinic]. To strengthen nails and promote faster growth, consider using a nail hardener. However, avoid products containing toluene sulfonamide, formaldehyde, alcohol, acetone, or dibutyl phthalate, as these chemicals can weaken nails [source: Mayo Clinic].
While waiting for your nails to regrow, adopt simple practices to maintain their health and prevent future damage. Choose footwear that allows ample space for your toenails, ensuring your toes can move freely. Regularly trim your nails to keep them short, as longer nails are more prone to tearing. Additionally, refrain from nail-biting, as this habit increases the risk of splits and tears [source: Aetna InteliHealth].
Maintain nail health by moisturizing with lotions or creams containing humectants like urea, phospholipids, and lactic acid. These ingredients help retain moisture, preventing nails from becoming brittle. If you have damaged fingernails, wear gloves during dishwashing or cleaning to minimize the risk of infection [source: Mayo Clinic].
Unhealthy nails can sometimes reveal underlying health issues. For instance, white nails may point to liver disease, while half-white, half-pink nails could indicate kidney problems. Yellow nails may suggest lung disease or diabetes, red nails might signal heart disease, and dark lines on nail beds could be a sign of melanoma. If you notice unusual nail discoloration, consult your doctor [source: Rauh].
