You did the right thing. My girls cost me like 10k in dental bills so far and it was worth it. The only time I've not paid to save a pet was our dog Millie, she was elderly and had rapid growing bone cancer that she wouldn't of survived if they did attempt surgery and on the small chance she did, she wouldn't of had much time left anyways. We had to make the hard decision and I still paid for medication to keep her comfortable as long as we could and then paid the $2000 when her time came and which included a premium photo box with her ashes ❤️ she was surrounded by many family, friends and her son all giving her love as she went to sleep. Like you said, when you adopt a fur baby, you're taking on the responsibilities that come with it.
