Hello there. My name isXXXXX am sorry to hear about Gus and his gingival hyperplasia. The most common cause of gingival hyperplasia in dogs is the actual bacteria in their mouth. Which I am sure you are aware of since you are cleaning his mouth and teeth after eating. It has not been documented in dogs that thyroid medications cause this. Most commonly it is caused by calcium channel blockers in dogs and more commonly cyclosporine in dogs. We also see it more commonly in boxers and possibly more represented in mastiff breeds like Gus. In humans one studied showed 11 out of 1000 patients on thyroid medications had gingival hyperplasia. Which is a very low rate. Again it hasn't been shown in dogs. So most likely this is not the cause of gyngival hyperplasia in Gus. I hope this helps and I hope this makes sense. Please let me know if you have any additional questions or concerns. I would be happy to help. Please do not forget to rate my response so I receive credit for my time. Thank you!
Is there a oral rinse that I can use until I see my vet next Monday to help with the inflammation?
