Angela Ferguson reported from Liverpool for BBC News on a groundbreaking dental surgery performed on a sloth at Chester Zoo. The sloth, named Rico, underwent the pioneering operation to cure toothache, marking a first for the team at Chester Zoo and dental experts from Newcastle University. The procedure was necessary after keepers noticed swellings on Rico’s face, leading to the discovery of two root abscesses.
The surgery, which lasted three hours, involved removing infected tissue surrounding two of Rico’s teeth. Dentist Fiona Beddis described the operation as a “step into the unknown,” highlighting the challenges of working on a sloth due to their unique anatomy. However, the team was thrilled with the successful outcome, marking a significant milestone for both the zoo and the university.
Dave Edwards from Newcastle University’s School of Dental Sciences explained that the surgery entailed removing the end of Rico’s tooth root and sealing it with special cement. Despite the complexities of working on a sloth, Edwards found the experience to be rewarding. Rico, who is 25 years old and resides with another sloth named Tina, has been closely monitored post-surgery to ensure his recovery progress. Chester Zoo’s dedication to caring for these unique creatures aligns with their commitment to the conservation breeding programme aimed at safeguarding two-toed sloths across Europe
