Will the leaves uncurl once I water the plant?

If the curling is due to mild underwatering, the leaves will often perk up and flatten out within a day or two. If they have been curled for a long time, they may stay slightly deformed.

Should I mist the leaves to help with curling?

Misting provides only temporary relief and can lead to fungal issues. Using a humidifier or a pebble tray is a much better way to increase humidity.

Silver Sword Philodendron: curling leaves, causes and fixes

Check these first

Feel the soil to see if it is bone dry.
Check if the leaves feel firm or soft and limp.
Measure the humidity level in the room if possible.

Likely causes

Underwatering
Most likely
How to tell: The leaves look limp and start to curl inward as the plant tries to conserve moisture. The soil will feel dry and pull away from the edges of the pot.
What to do: Water the plant deeply until water runs out of the drainage holes. Ensure you are watering every 7 to 10 days when the top inch of soil is dry.
Low Humidity
Possible
How to tell: The leaves curl at the edges and may feel crispy to the touch. This often happens during winter when indoor heating dries out the air.
What to do: Group your plants together to create a more humid microclimate. You can also place a humidifier nearby to keep the air moisture levels higher.
