Preheat oven to 500° with a pizza stone on the bottom rack.
Roll out pizza dough on a floured pizza peel or upside-down large baking sheet. Press garlic slices into surface of dough and season with salt. Slide pizza from peel onto hot pizza stone in oven.
Bake pizza until puffed, blistered, and browned, 10 to 12 minutes. Remove from oven, drizzle liberally with oil, and top with tomatoes and basil. Sprinkle with a pinch of sea salt.
