A cleaning will range from $150-$500 depending on what is included. Extractions would be extra, but baby teeth removal shouldn't cost too much. As they get older, the need for dental radiographs increases (unfortunately not all vets do them) and more in depth work needs to be done. Prices vary by area, but also by surgical protocol. If the vet is using iso or sevo, monitoring constantly, preop bloodwork, IV/fluids, pain meds, antibiotics it all changes the price. And the ones who don't do radiographs will probably be cheaper, but that may not be a good thing.
Opinions are definitely varied about anesthesia-free dentals. I'm not going to say they are bad or don't work, but the experts in the field don't like it for some reasons that I'd consider good ones. I definitely understand anesthesia is scary and some may want to avoid it and that is fine if your vet agrees.
but the vets who choose to use it may actually feel that it is best...
