Charles H. Spurgeon on Psalms 58:6

Break their teeth, O God, in their mouth. If they have no capacity for good, at least deprive them of their ability for evil. Treat them as the snake charmers do their serpents, extract their fangs, break their teeth. The Lord can do this, and he will. He will not suffer the malice of the wicked to triumph, he will deal them such a blow as shall disable them from mischief. Break out the great teeth of the young lions, O Lord. As if one brute creature had not enough of evil in it to complete the emblem of ungodly nature, another specimen of ferae naturae is fetched in. For fierce cruelty the wicked are likened to young lions, monsters in the prime of their vigour, and the fury of their lustiness; and it is asked that their grinders may be smashed in, broken off, or dashed out, that the creatures may henceforth be harmless. One can well understand how the banished son of Jesse, while poisoned by the venomous slander of his foes, and worried by their cruel power, should appeal to heaven for a speedy and complete riddance from his enemies.
