Tooth decay isn't a generic slow wearing down of all of your enamel but instead a concentrated attack on a small location of enamel from food for example being consistently stuck in a small fissure. A big thing you use dentists for is managing plaque that makes these issues worse, and probably also will help block the effects of these lozenges. Polishing your teeth actually removes small quantities of enamel with the goal of making the teeth a bit smoother so there are less places for things to get stuck. Dentists also are dealing with issues where your teeth get cracked or otherwise damaged from grinding or hard foods. I can't imagine just indiscriminately throwing layers of enamel at the problem is going to leave you in a solve where "there wouldn't be any point of going to a dentist".
