Thanks for using Petco Pet Education Center, formerly Petcoach! It is hard to tell from the pictures but it looks like Ginger may have broken her tooth. I recommend making an appointment with your vet when they open to take a look at it. Though she isn’t acting painful, it may become painful or infected. There isn’t anything you can do at home and no safe medications you can give for pain. If it is broken, she will likely need to undergo anesthesia to have the tooth removed. The vet that looks at it will be able to help more once a diagnosis is made. Good luck and kisses to Ginger!
