Yes, it's possible to remove dents from most types of vinyl flooring. The method for removing dents will vary depending on the type of vinyl flooring you have. For sheet vinyl flooring, you can use a hairdryer or hot water to soften the material. Then, use a rolling pin or other heavy object to smooth out the dent. For luxury vinyl tile (LVT) or luxury vinyl plank (LVP) flooring, you can use a heat gun or hot water to soften the material. Then, use a heavy object to press the dent out. It's important to note that with any type of vinyl flooring, you should always test any cleaning or repair method on a small, inconspicuous area first to ensure it won't damage the flooring.
