    The saltwater crocodile isn't found in Africa where the plover lives. For a long time it was thought that the bird has a symbiotic relationship with the nile crocodile but I believe this has been rejected. I don't believe plovers clean bits of food from a croc's mouth, not any more than they pick leeches. For one thing, crocs tend to swallow prey whole, or bolt it down in large chunks. Food doesn't tend to get trapped, especially since the teeth are conical, and there's ample space between them. And crocs gape as a warning to possible sources of danger; they don't do it to let birds enter.

    Herodotus claimed that Nile crocodiles have a symbiotic relationship with certain birds like the Egyptian plover(It is also sometimes referred to as the Crocodile Bird because it is famous for its symbiotic relationship with crocodiles (National Geographic 1986), which enter the crocodile's mouth and pick leeches that have been feeding on the crocodile's blood, but there is no evidence of this interaction actually occurring in any crocodile species, and it is most likely mythical or allegorical fiction.

    The Egyptian Plover bird and the crocodile. You might think that if a bird landed in the mouth of a crocodile, the crocodile would eat it. Well, not the Egyptian Plover bird. Egyptian Plovers and crocodiles have a unique symbiotic relationship. Because crocodiles can’t use dental floss, they get food stuck in their teeth. All that food rots their teeth and probably causes them some pain. When a crocodile feels the need for a good tooth cleaning it will sit with its mouth wide open. The Egyptian Plover bird recognizes this invitation, and if one is nearby it will fly into the mouth of the crocodile, eat the food stuck in its teeth, and fly away. The plover gets a meal and the crocodile gets a valuable tooth cleaning: they both benefit.

    They don't. Although the claim was made by Herodatus, it has never been substantiated and has been accepted on faith by some writers. As far as the crocs go, you are probably thinking of the Nile crocodile, not the salt-water. They lie on the banks with their mouths open as a means of thermoregulation, which may have given rise to the story.
