they aren’t just numbing one kind of nerve, they’re numbing all nerves in the area, your sense of taste is collateral damage

All 5 of the main senses (a lot more have been identified but that’s another topic) require nerves to carry information to your brain. When the area is numb, the nerves are being prevented from doing this. So your brain isn’t receiving the information, even if the stimulus is present (in the case of taste, the stimulus is your food).

They *are* two different senses, they’re just both getting numbed. The anesthetic turns off ALL nerves (and therefore all senses) in the affected area.
