The tooth’s hardness also helps them scrape off any pieces they may have missed while biting down on their food. These layers are made up of calcium phosphate crystals, which protect against acidity, corrosion, and even some types of antibiotics. Some people might not know this, but sharks’ teeth actually have a problematic protective layer for many materials to penetrate. The teeth of sharks are resistant to acid and fluoride. 10) The teeth of sharks are resistant to acid and fluoride. Like humans, Tiger sharks use their front set of teeth to ripple and tear food while using their back teeth to grind up the pieces. ![]() Their front teeth are more limited, while their bottom teeth tend thicker and longer for tearing apart food more efficiently. Their long, narrow teeth are serrated, which allows them to catch larger prey. ![]() ![]() 9) Tiger sharks have the most prominent teeth among all shark species. This shark, which lives in deep waters off the coasts of northern Australia and New Zealand, uses its tiny teeth to catch small fish like lanternfish. The Dwarf Lantern shark is only about 17 centimeters (6.3 inches) long. 8) The Dwarf Lantern shark has the tiniest shark teeth. This technique provides a more significant portion of food and allows sharks not to waste any part of what they catch. The lower jaw is then brought forward to drag the shark’s prey into its mouth. With their upper jaw pushed forward, sharks can quickly grab pieces of flesh from larger animals such as turtles and seals. The Great White shark uses a “take and drag” method while hunting, which allows for a wide range of movement when attacking prey. 7) The Great White shark has the most powerful jaws of all species. Instead, sharks use their teeth to tear pieces off of prey by moving the upper jaw slightly forward over the target, then dropping down on them quickly, tearing off chunks. Sharks aren’t like humans who chew and swallow their food. 6) Sharks don’t chew their food they tear it apart with their teeth instead. The teeth are triangular in shape, so thin and sharp they can easily pierce through the skin of their prey.īecause Great Whites have three rows of teeth on the top and two rows on the bottom, it is nearly impossible for them to lose all of their teeth at once unless they are caught by fishermen who tease them with baited lines until their teeth fall out. On average, a Great White Shark has approximately 3000 teeth at one time in its mouths with around 15 rows of teeth. 5) Great White sharks have the most teeth among all species. This is helpful to them because they immediately have a complete set of teeth and won’t be biting their prey with flat, molar-like teeth like some sharks. Sharks are born with their complete set of teeth. 4) Sharks are born with complete sets of teeth. Luckily for sharks, their teeth can grow back in just a few weeks. Sharks use their teeth so much that sometimes they may come out of the gum while chewing. Sometimes this happens so often that they may go through thousands of teeth in just one lifetime. Most sharks constantly lose and replace their teeth throughout their lives. 3) Sharks can go through up to 30,000 teeth in a lifetime. The shape of sharks’ teeth allows them to break down prey into small enough pieces to go through the shark’s “gill rakers,” where tiny structures poke out and sort of comb through these pieces before sending them further down the digestive tract. Sharks do not chew food as we do they use their gills to extract oxygen from water while pushing it over their gills for gas exchange with the blood circulatory system to get energy. Sharks’ teeth are meant to help them catch and eat their prey, including other marine animals such as fish and squid, not humans! Some people think this is why many people fear sharks, but the truth is much different. Sharks have a mouthful of teeth that can be pretty intimidating.
