One of my favorite strategies to save money on dental materials and supplies is to utilize a Walmart price tracker like PriceLasso. When the price on common consumables like Cotton Rolls to absorb saliva and keep the area dry, and Gloves, Masks, and Gowns goes down in price, I try to stock up for many months.

I like the price history charts which show the ebbs and flow of Walmart prices, which can often fluctuate like crazy.

For printer ink and paper, I use PriceLasso's Office Depot price tracker, which can result in savings of 30-50%.
