Sometimes you notice that one of your toenails is starting to grow differently. Maybe the edge is curling inward, the nail looks more rounded than usual, or it seems to be growing toward the skin. If you have been wondering how to make curved toenails grow straight, the first thing to know is that the shape of your toenail can be affected by several things, including how you trim it, the shoes you wear, an injury, or your natural nail shape.
A mildly curved toenail may grow in a straighter direction when you remove some of the pressure or nail care habits that are causing the problem. Cutting your toenails straight across, avoiding tight shoes, keeping your feet dry, and treating an underlying nail problem can help. However, a very curved nail may continue to grow that way, especially if its shape is natural. If the nail is painful, swollen, red, producing pus, or repeatedly growing into the surrounding skin, it is better to see a doctor or podiatrist. Mayo Clinic

Can Curved Toenails Grow Straight Again?
It depends on why the toenail is curved in the first place. If the change is related to trimming habits, pressure from shoes, repeated injury, or another problem that can be corrected, changing those habits may help the nail grow more normally over time. Toenails also grow slowly, so you should not expect a curved nail to change shape overnight.
However, some people naturally have more curved toenails. In this case, you may be able to prevent the nail from becoming painful or ingrown, but you may not be able to permanently change its natural shape with home care alone.
Are Curved Toenails and Ingrown Toenails The Same?
No. A curved toenail simply means the nail has a curved shape as it grows. An ingrown toenail is a specific problem where the edge or corner of the nail grows into the skin around it.
A very curved toenail can increase the chance of becoming ingrown, particularly when combined with tight shoes or incorrect trimming. So, if your curved toenail is not painful and is not pressing into the skin, you may simply need to keep an eye on it. If the skin around it becomes red, swollen, tender or starts producing pus, that is a different situation and should be treated as a possible ingrown or infected toenail.

What Causes Toenails to Grow Curved?
There is no single reason why a toenail may start growing curved. Your nail shape, everyday habits and the condition of the nail can all play a role.
1. Improper nail trimming
The way you cut your toenails can affect how the edges grow. Cutting them too short or rounding the corners can encourage the nail to grow toward the surrounding skin. This is especially important if you already have naturally curved nails.
Instead of following the shape of your toe and cutting deeply into the corners, trim the nail straight across and leave a moderate amount of length.
2. Tight or narrow shoes
Your toenails need enough room inside your shoes. Shoes that squeeze the toes together can put repeated pressure on the nail and the skin around it.
If you regularly wear shoes that press against your toenails, especially for several hours at a time, that pressure can contribute to nail problems and increase the risk of an ingrown toenail. Shoes with enough room around the toes can reduce this pressure.
3. Toe injury or repeated pressure
A toe injury can change the way a nail grows. You may have hit your toe against something, dropped something on it, or experienced repeated pressure from activities or footwear.
Sometimes the change is not obvious immediately. You may only notice that the nail looks different as it continues to grow out.
4. Genetics and natural nail shape
Some people naturally have toenails that are more curved than others. The shape of your toe and nail can affect how the nail grows, and naturally curved toenails are one of the factors associated with ingrown toenails.
If your toenails have always been curved but are not painful or infected, you may not need to straighten them completely. The main goal is to keep them healthy and prevent the edges from growing into the skin.
5. Fungal nail infections
A fungal nail infection can change the appearance and shape of a toenail. You may notice discoloration, brittleness, cracking, lifting or other changes to the nail.
If your curved toenail has also become thick, yellowish, brittle or crumbly, do not assume that trimming it differently will solve the problem. It may need to be checked by a healthcare professional so the cause can be identified and treated properly.
6. Excessive sweating
Feet that stay damp for long periods can create conditions that contribute to some foot and nail problems. This is particularly relevant when sweaty feet are combined with tight footwear that does not allow much airflow.
Keeping your feet clean and drying them properly after washing can help you maintain healthier feet and nails.
7. Improper nail care
Picking, tearing or cutting into the sides of your toenails can irritate the skin around the nail and make problems worse.
It can be tempting to cut away the part of the nail that looks curved, especially when it seems like the quickest way to make the nail look straight. However, cutting too far into the corners can increase the risk of an ingrown toenail.
8. Toe or nail anatomy
The natural shape of your toe, nail and surrounding skin can affect how your toenail grows. This means that sometimes a curved nail is not the result of something you are doing wrong.
When the shape is persistent or the nail repeatedly grows into the skin despite good nail care, a podiatrist can examine it and determine whether you need further treatment.

How To Make Curved Toenails Grow Straighter
There is no guaranteed home method that can permanently change the natural shape of a toenail. However, you can remove some of the things that encourage the nail to curve or become painful.
1. Trim toenails correctly
When trimming your toenails, cut straight across rather than rounding the corners to match the shape of your toe. Avoid cutting the nail extremely short because this can increase pressure on the nail edge.
If your nail is already painful or growing into the skin, do not keep cutting away the sides in an attempt to straighten it. This can make an ingrown toenail worse. The NHS specifically advises people with ingrown toenails not to cut or pick at the affected nail while it grows out.
2. Give your toes more room
Take a look at your everyday shoes. If your toes are squeezed together or the front of the shoe presses against your toenails, your footwear could be contributing to the problem.
Choose shoes with enough room around the toes and avoid shoes that press directly against a painful or irritated nail. This is especially important if you spend a lot of time walking, standing or exercising.
3. Keep feet clean and dry
Wash your feet regularly and dry them properly, including the areas between your toes. If your feet sweat a lot, changing damp socks and giving your feet some time to stay dry can also help with general foot care.
If you notice other nail changes such as thickening, discoloration, cracking or crumbling, have the nail checked rather than treating the curved shape alone. Fungal infections can cause noticeable changes to the toenail and may require proper treatment.
4. Avoid picking or tearing the nail
Try not to pull off pieces of your toenail or dig into the corners when they start to curve. These habits can injure the nail and surrounding skin.
If there is a small rough edge, trim the nail carefully when appropriate rather than tearing it away. If the nail is already growing into the skin, leave the problem alone and get professional advice instead of trying to dig the nail out yourself.
5. Treat an underlying nail problem
If the nail became curved after an injury or has other changes such as thickening or discoloration, treating the underlying problem may be more useful than trying to force the nail into a straighter shape.
A healthcare professional can examine the nail and determine whether you have an infection, an ingrown toenail or another nail condition that needs treatment.
6. See a podiatrist if the nail keeps curving
If you have tried improving your nail care and footwear but the toenail continues to grow painfully into the skin, a podiatrist can take a closer look at the nail.
This is particularly useful when the problem keeps coming back. Depending on the condition of the nail, a foot specialist may recommend a conservative treatment or a procedure to remove the part of the nail that is causing the problem.
How to Prevent Curved Toenails
Even if you cannot completely change the natural shape of your toenails, you can reduce some of the problems that make curved nails painful or more likely to become ingrown.
1. Cut toenails straight across
Do not curve the nail around the front of your toe when trimming it. Keep the cut relatively straight across and avoid digging into the corners.
2. Avoid cutting them too short
A very short toenail can be more vulnerable to pressure from footwear. Leave the nail at a moderate length rather than cutting it down as far as possible.
3. Wear properly fitting shoes
Your shoes should not squeeze your toes or constantly press against your toenails. Give your toes enough space to move comfortably, especially if you spend much of the day in shoes.
4. Protect toes from repeated injury
If your activities involve a lot of running, kicking or pressure on your toes, wear suitable footwear and try to protect your toenails from repeated trauma.
A toenail that has been injured may grow differently for a while, so keeping an eye on it as it grows out can help you notice changes early.
5. Do not pick or tear toenails
Picking at your toenails can damage the nail and surrounding skin. Use clean nail clippers when trimming and avoid ripping off pieces of nail, even when they are catching on your socks.
When Should You See A Doctor or Podiatrist?
A slightly curved toenail does not always require medical treatment. However, you should get professional advice if the nail becomes painful, swollen, very red or starts producing pus.
You should also seek medical care if the redness or swelling appears to be spreading, you feel feverish or unwell, or the problem is not improving with basic care. People with diabetes or conditions that cause poor blood circulation should be particularly careful with foot problems because even minor injuries can become more serious.
If the same toenail keeps becoming ingrown, a podiatrist can also help you understand why it keeps happening and discuss treatment options.
How Are Severely Curved or Ingrown Toenails Treated?
Treatment depends on what is happening to the nail. A healthcare professional will usually examine the nail and surrounding skin before deciding what needs to be done.
1. Lifting the nail edge
For a mildly ingrown nail, a healthcare provider may carefully lift the edge of the nail and place a small piece of cotton, dental floss or another material underneath it. This separates the nail from the skin and allows it to grow above the skin edge.
This is different from simply digging underneath a curved toenail yourself. If the nail is painful or already embedded in the skin, it is safer to have it assessed first.
2. Nail bracing or splinting
Some ingrown toenails can be managed by using a splint or another method that helps keep the nail edge away from the surrounding skin.
Healthcare providers may use a gutter splint under the nail in some cases. The aim is to allow the nail to grow above the skin rather than continuing to press into it.
3. Partial nail removal
When an ingrown toenail is more severe, particularly when there is significant inflammation, pain or pus, a healthcare provider may remove the part of the nail that is growing into the skin.
The toe is usually numbed first, and only the affected portion may need to be removed. The nail can then grow back over the following months.
4. Treating an infection
If the skin around the nail is infected, treatment may be needed alongside care for the nail itself. Signs of infection can include pus, increasing redness, swelling, warmth and significant pain.
Do not try to cut away an infected or severely ingrown nail at home. A healthcare professional can determine whether you need medication or another treatment.
5. Preventing recurrent ingrown nails
When an ingrown toenail keeps coming back, a healthcare provider may recommend a procedure that removes part of the nail and, in some cases, prevents that portion from growing back.
Recurrent cases may be treated by removing part of the nail along with the underlying nail tissue. Chemical treatment, laser or other methods may be used to prevent regrowth of that section.
Frequently Asked Questions
Can curved toenails grow straight again?
They can sometimes grow straighter when the cause is related to things such as improper trimming or pressure from footwear. However, a naturally curved toenail may continue to grow with that shape. The goal is often to prevent the nail from becoming painful or ingrown rather than trying to completely change its natural shape.
Why does my toenail keep growing curved?
Your toenail may keep growing curved because of its natural shape, incorrect trimming, tight shoes, previous injury, nail infection or the shape of the toe and surrounding tissue. If the same nail keeps causing problems, a healthcare professional can help identify the underlying cause.
Can I straighten a curved toenail at home?
You can improve the conditions around a mildly curved toenail by trimming it correctly, avoiding tight shoes and keeping your feet clean and dry. However, there is no guaranteed home treatment that can permanently straighten a naturally curved nail. If the nail is growing into your skin, avoid digging into it or repeatedly cutting the sides.
Can curved toenails become ingrown?
Yes. A very curved toenail can grow into the surrounding skin, particularly when combined with tight shoes or incorrect trimming. An ingrown toenail can cause pain, redness, swelling and sometimes infection. Mayo Clinic
Can fungal infections cause curved toenails?
A fungal nail infection can change the appearance and shape of a toenail. It may also cause discoloration, thickening, brittleness, cracking or lifting. If your curved nail has these changes, it is worth having it checked rather than assuming that the curve is simply your natural nail shape.
How long does it take for a curved toenail to grow out?
Toenails grow slowly, so changes in the nail will take time to become noticeable. If you are correcting a trimming or footwear habit, you may need to wait for new nail growth before you can see a significant difference. The exact time varies depending on the individual nail and the reason it became curved.
Conclusion
A curved toenail does not always mean that something is seriously wrong. Sometimes it is simply the natural shape of the nail, while other times it can be linked to trimming habits, tight shoes, injury or a nail infection.
If you want to encourage your toenails to grow as normally as possible, start with simple nail care. Trim them straight across, avoid cutting them too short, give your toes enough room in your shoes and do not pick or tear the nail. If the nail becomes painful, swollen or infected, or keeps growing into the skin, it is time to have it checked by a healthcare professional.
