You might want to reconsider the Convenia. This is a link to information from a vet, Lisa Pierson, DVM, regarding the risks of giving a cat Convenia. Many vets will give a long acting antibiotic injection rather than bother their clients with having to give pills. The problem is that once the drug is given, there's no way to interrupt its action. Convenia is maximally active for 1 - 2 weeks but lasts for up to 2 months. Its primary action, based on the drug company's information is for skin infections. It does not have an indication for dental issues. Just a personal note, my vet will not prescribe Convenia.
GI issues are not uncommon with Clavamox and Clindamyacin. You can give probiotics to offset the issue but you need to separate the dosing by a few hours.
