Determine what breed of shark teeth you are looking for. Great White teeth are the most popular replica for sale, due to the law making the import of real great white teeth to the U.S. illegal. After you have determined which genre of teeth you would like to purchase, find a website that sells cast shark teeth like BoneClones.com.
Search the website for your desired type of teeth, including the word "replica." This will provide you a list of teeth cast like sharks, but not authentic ones, so the price is much lower. These replicas are very realistic and a perfect illustration for the classroom, when teaching the anatomy of the shark.
Click on the tooth you wish to order after browsing the selection, and select the quantity you desire. Ordering enough for the entire class provides children with a unique souvenir of the school year. Fill in your shipping and payment information and click "Submit" to order your teeth.
Visit your local museum or aquarium gift shop to shop for replica shark teeth, if you are not committed to a particular breed and would prefer not to order online. A local nature store or local tourist trap, if you live near the ocean may also be able to supply you with some shark teeth. Finally, many jewelry stores sell teeth cast like sharks as necklace charms, and may be able to direct you to a wholesale dealer, if you need to purchase teeth in a large quantity.
