Instructions to Trim Thick Toenails: 6-Step Plan
First, get the right tools. This is critical – the right tools make for an easy job clipping even the thickest nails
The products below are the ones we recommend to our patients and they are also affiliate links so we may receive a small commission at no additional cost to you if your order from the link.
- Nail Grinding Tool: The most effective one we have found is the PediNova Electric Nail and Foot Care Kit – a podiatry-grade electric nail grinder and thinning tool. It comes with bits specifically made to work on thick toenails. The large cone, small cone, and disc bits are made from long lasting sapphire and diamond chips. We have tried many of these units over the years and this is best one we have found and the one we recommend to our patients. The video below shows how to use the Pedinova Nail Grinder.
- Heavy duty podiatry-grade toenail clippers: We recommend ClipPro nail clippers for our patients.
The ClipPro Toenail Clipper is the best consumer nail clipper we have found for extra thick and irregular nails. Its jaw opens up to over 1″ wide and the top of blades is slightly curved to contour around your nails. It is very easy to maneuver and provides a clean and smooth cut. Only use professional grade toenail clippers like these for thick nails – don’t try to thin thick toenails with fingernail clippers. It’s usually more painful as they just don’t cut these thick nails very well and you end up kind of gnawing at the nail with the nippers.
Follow these instructions for the best outcome in thinning and shortening thick nails
- Soak your toes in warm water for five to 10 minutes. This will help soften the nail and allow you to more easily cut the thick nail.
- Shorten the nail: Use the ClipPro nail clipper to shorten the nail if it is excessively long. The ClipPro opens wider then most clippers making much easier to trim thick toenails. If the nail is particularly thick you can also use the ClipPro to trim the nail from the top.
- To Thin the Top of the Big Toe Nail: While the nails are still a bit damp, use the Large Sapphire Cone Bit (Figure 7) included with PediNova Electric Nail Grinder, to grind the thickened nail from the top. Use gentle pressure and grind it thinner until it is normal thickness or starts to get warm. If it gets warm, stop and then do a little more later or the following day. Continue grinding a little each day until the nail is normal thickness.
- To Thin the Sides of the Big Toe Nail: Use the Long Sapphire Bit (Figure 5) that comes with the PediNova Grinder.
Use gentle pressure going up and down the side of the nail. This will thin the sides and help prevent ingrown toenails since the shoe will no longer press into the thickened nail border.
- To Thin the Smaller Toenails: Use the Long Sapphire Bit or Small Sapphire Bit (Figure 8). As above, use gentle pressure and grind the nail until it is normal thickness. To prevent injury, stop grinding if it gets warm then do a little more later that day or after your next bath or shower.
- To Shorten the Nail: Start with the ClipPro Nail Clipper (Figure 2) to remove any loose pieces that extend beyond your toes. Then sand it smooth with the Sapphire Sanding Disk Bit (Figure 9). Hold the disk to the end of the nail. Clip and sand shorter and shorter until you have reach your desired length. Clip your toenails straight across. Rounded corners tend to lead to ingrown nails.

Nail Polish for Thick and Fungal Toenails
For women, toenail polish can help disguise the nail roughness and thickness and is a nice finishing touch for thick nails. For our patients we recommend Dr.’s Remedy Natural Nail Polish anti-fungal nail polish, It contains Tea Tree Oil and Garlic Bulb Extract (found to have anti-fungal properties).
Unlike most nail polishes, it does not contain Formaldehyde (a chemical which has been proven to cause cancer) DBP (a potential developmental and reproductive toxin) and Toluene (a chemical that the EPA restricts in our drinking water because it can cause nervous system disorders as well as damage to the liver and kidneys)
Healthy feet allow for regular exercise and a happy healthy feet.
