My pug's teeth are getting yellow from tartar buildup. :shame: I've been told that she needs a deep cleaning, and would have to be put under anesthesia. This worries me.. I'd rather not put her under any risk if it's not totally necessary. I do send her to the dog spas for teeth cleanings but I guess they're not helpful. I wonder if the deep cleanings would get rid of all the tartar? Can someone give me their opinions on deep cleanings?
