I understand your anxiety and dilemma only too well. This is an example of justified anxiety about anesthesia being weighed against allowing ongoing disease to progress.
Unchecked dental disease, especially when infection is present, often "seed" bacteria to the blood stream with disturbance such as chewing or other normal activities. That can in turn cause colonization in such places as the heart valve leaflets, kidneys and pancreas. Indeed, a paper published last year in the human literature, tied untreated periodontal disease to human pancreatic cancer. So that is the benefit of addressing dental disease regularly and thoroughly, avoiding progression and new problems, some serious.
The down side, is the risk of death with poorly administered general anesthesia, and much less common, but still plausible unseen and unknowable idiosyncratic adverse reactions.
In a young, otherwise healthy animal such as yours, the risk of anesthesia may be less.
In a brachycephalic (short-faced) breed, there are added challenges and risks with anesthesia. No question, careful management of this and every pet is of course warranted.
In the end, only you can weigh the risks and benefits of going ahead with the procedure. If in doubt, get a second opinion from a dental specialist in your area.
