Hello. I typically don't post much but I have this 12 1/2 yr Coton de Tulear lightly sedated right now. He has had a draining track from his planum 1/3 down from his medial canthus and an opening in his mouth. I have included photos of the canine 204 and the radiograph of that tooth too. I am not sure how to repair a fistula and if they are left open. I am thinking of referring him to a specialist since he also has 2 fractured teeth 108/208 and an opening below 408. Thanks for your help.
