Thanks for the tip. We tried Opti-rinse, also recommended at our dental clinic and sold there. However, we really didn’t need it, as floridation is already covered by our toothpaste. Our clinic was recently bought by one of the investment companies that are taking over the dental and veterinary industries in Canada, and upselling is part of their business model. The mouthwash recommended by the previous commentor looks more like what we need.
