It is possible that Stella may have a tooth root abscess, a cyst, granuloma, benign or malignant mass, among other causes. I'm glad to hear that she is acting normally, but she should be examined by her vet to address the underlying cause. If she is diagnosed with a tooth root abscess, her vet will be able to discuss a dental extraction and antibiotics with you. Otherwise, a fine needle aspirate (FNA) can be performed to evaluate the type of cells present in this growing lesion to aid in determining the underlying cause.

I agree that I am suspicious of an abscess. This could be an abscess in the skin or it could be a tooth root abscess. A tumor is also possible but they tend to grow slower. I do not think it is well into any type of healing process at this time. I recommend to take Ellie in to see the veterinarian tonight or tomorrow. You need to know if it is related to a tooth root problem or not. The doctor will also start her on antibiotics to help to fight the infection quickly. I hope that this helps and please feel free to post any additional questions.
