They have a specialized structure called a radula that has rows of teeth that point backwards, it works like a tongue and rasps away at food and serve as a conveyor belt carrying food particles towards the digestive tract.

they have things called radula. The strange band of rows and rows of teeth in slugs, snails, nudibranchs, whelks, chitons, limpets, and certain other mollusks is known as a radula (plural: radulae). If you've ever kept an aquarium in which you let a nice carpet of algae grow on the sides, and if you also had some snails in it, then you very likely noticed interesting little tracks through the algae and you probably thought that the snails were navigating tiny riding lawnmowers up and down the sides. However, the truth is almost as bizarre. The radula can be extended through the mouth and moved up and down by a complex series of muscles. The radula acts like a rasp, tearing off pieces of algal mat which are ingested, thus leaving the tracks. The teeth are composed primarily of chitin, which is tough, durable, hard, and, in this instance, sharp, giving them the appearance, under the microscope, of very formidable weapons indeed. Relative to the size of the body, the radula can be enormous. In some snails, I have found radulae nearly as long as the body. The radula is like a flexible parabola lined with several rows of teeth and the muscles pull it back and forth, making it a remarkably effective feeding mechanism—if you like algae.

Slugs have 14 rows of razor sharp teeth and snails use what looks like a tongue to emaciate their prey.

Not teeth as we know, however they do have a hardened set of scrapers that they scrape the inside of a fish tank to free algae to eat. Slugs are similar except they eat plants and fruit.

I don't think so... but I remember one time i had some fireworks for the fourth of july (Blackcats) and I set it by a slug and they started eating it then i lit the firecracker and blew it to pieces. Long story short never saw any teeth.

That's a good question!
I've never really thought about that...
I guess they do as they basically ruin flowers and stuff, they might do that using their teeth!?
