Trivia: A video game from Sega in 1972 was called Killer Shark, considered the first video game in the horror genre. The object of the game was to shoot at a giant shark with harpoons. This game can be seen in the seaside arcade in the movie.
Trivia: Often touted as the first "summer movie;" what this refers to is the now-typical marketing practice of doing most of the advertising before the film's release to build up hype ahead of a big nationwide opening weekend (at the time most movies opened in a limited number of markets to build a reputation). By the 80s this model was followed by big tentpole "summer blockbusters," but nowadays is the norm for the majority of studio releases year-round.
Suggested correction: When Hooper uses the knife to pry to tooth out, it took very little effort, suggesting that the tooth wasn't wedged into that spot, but merely just resting in that spot.
The shark tooth was inserted into the wood by the prop crew with its flat root side down, which would have been impossible to have occurred during the attack on the hull. As to the statement that the tooth was "merely just resting in that spot" then Hooper would not have needed to use the blade to remove it from the wood, plus the fact that since it was underwater it would have floated away during the hours after the attack. But it did not float away, so it must have been at the very least snugly fit into the wood hull. Still impossible.

The original mistake says that the root of the tooth was embedded In the wood. Not possible since it should be the sharp end in the wood and the root showing on top (as described in the mistake).
