Examples: Hunting down lost items, finding the path when you have lost your way, giving you strength in social situations, cursing enemies
Tips: Find shark teeth along the shores of oceans early in the morning while the tide is low. Sharks are very active at night, and often lose a tooth while biting into flesh, so early morning gathering is highly recommended. Ethically speaking, and out of respect/safety with sharks, you should try to stick to this method instead of hunting the teeth from a living shark. Wait for the teeth to come out naturally, or gather teeth from a dead shark, but do not hunt these beautiful animals for teeth alone. You can also purchase shark teeth in bulk, but I find it more special to use teeth that you have found on your own, as it is more connected to you as a person. I have gathered all of these teeth in my collection while visiting shorelines and ocean states throughout my life, so it is very doable with some incentive. Good luck!
