A great white shark typically has about 300 teeth.
Great whites (Carcharodon carcharias) carry several rows of broad, triangular, serrated teeth designed to cut through flesh. Only the front rows are normally used, while teeth behind them stand ready to move forward. When a tooth is lost or damaged, another can replace it, creating a continuous conveyor-belt-like supply throughout the shark’s life.
The figure 300 refers to the shark’s total teeth across its working and replacement rows, not necessarily the number visible in a single open mouth. Individual counts can vary with age, anatomy, and how researchers define a tooth row, so “about 300” is more accurate than an exact universal number.
Great white teeth are especially recognizable because of their large triangular shape and coarse serrations. This differs from the narrower teeth of some fish-eating sharks. The shark’s jaw is powerful, but the teeth—not chewing—do most of the cutting; great whites generally swallow pieces rather than grind food.
