Toothpaste

I've finally found a toothpaste that does not contain the dental enzyme, sugar, or ingredients that I suspect they're allergic to -- it's a formula as old as dirt, mainly bicarbonate (baking soda), with some almond oil to tempt their taste buds, plus beeswax to make the bicarbonate stick to their teeth for a while to do its job.  It's trickier to use, as it's a semi-solid and comes in a little pot instead of a tube.  So far I'm pleased with the result.  It's made by the same company that makes the dental enzyme chews that almost killed Gidget (trachea collapse from dental enzyme softened cartilage) - it's made in Mexico by Sentry and distributed by Sergeant in the USA, it's Sentry HC Petrodex Ultra - Advanced Veterinary Cleaning Paste.  I found it at PetSmart.
