Instructions for removing a bear tooth

The collection of teeth from hunter-harvested bears is a critical component in Wisconsin's bear management program. These teeth allow biologists to determine the age structure of the population, the age when females first reproduce and consecutive cub production. Hunters are critical in the department's ability to scientifically manage Wisconsin's bears. Your cooperation is appreciated, thank you.

In-person registration stations will not collect or submit a tooth on behalf of hunters. It is the hunters' responsibility to submit a tooth to the department. It is not an option.

Step 1. Locate the first upper-premolar which is the first tooth located behind the upper canine.

Step 2. Utilize a knife to cut the gum tissue around both sides of the tooth. Cut as deeply as possible
into the tissue to ensure the root can be removed without breaking.

Step 3. Utilize a small screw-driver to gently loosen the tooth.

pliers to further loosen the tooth.

Step 5. Examine removed tooth to ensure the root is intact. If the root is not intact or you are not sure,
remove the other upper-premolar.

The root of the tooth is sectioned and stained. Once stained the tooth can be examined for growth rings which deposit annually in a manner similar to growth rings on a tree. Furthermore, due to the nutritional stress associated with raising a litter examining female teeth for rings that are close together is an indicator of past reproduction.
