Gardner syndrome (also known as familial colorectal polyposis) is a rare au- tosomal dominant condition. It is characterized by osteomas, familial polypo- sis of the colon, cutaneous epidermoid cysts, soft tissue tumors, as well as certain dental anomalies. We report the case of a 29 years old male patient with Gardner’s syndrome who presented with no intestinal polyps but instead had an osteoma on the left side of the mandible and multiple impacted teeth. The case showed the possibility to manage the multiple impacted teeth with- out jeopardizing the health of the teeth in terms of mobility or significant root resorption taking into consideration the increased bone density in such patients.
