How to Collect & Polish a Shark Tooth

Visit the ocean. The ocean's tide will wash shark teeth up onto the beach for easy collecting. Look for white shark teeth, which are newer, and fossilized teeth that may be black or brown in color. Wade into the water to look for teeth as well.

Place shark tooth into a sealable container, such as a plastic bag, for safekeeping until you bring it home.

Wash the shark tooth to remove dirt. Mix liquid dish soap with warm water to wash the tooth, and brush the surface with an old, soft toothbrush to remove any additional debris.

Place the tooth on a paper towel and let it dry overnight.

Plug the Dremel tool into an electrical socket. Attach the roughest grit polishing bit to the tool.

Turn on the tool and place the top third of the polishing bit against the shark tooth. Hold the bit flush against the tooth to prevent scratching. Polish each section of the tooth with the rough grit bit using small, clockwise movements.

Remove the rough grit bit and replace it with a finer bit. Polish the entire surface of the tooth with the finer bit. Polish the tooth until the surface starts to shine.

Wipe the surface of the tooth with the soft cloth to remove any dust. Polish any scratches or remaining rough spots with the finest grit bit.

Apply a quarter-size amount of polishing compound to the soft cloth.

Rub the surface of the shark tooth with the polishing compound and soft cloth until it shines.
