digestive system - Long term liquid food diet by blending/grinding all quality foods one would normaly eat, not any weight loss or prepared drinks

I want to know what are the effects of not using your teeth to grind foods but preparing it before eating with blending and grinding them into a liquid.

Here I am not talking about any weight loss or fitness industry prepared drinks. I mean the ordinary raw and cooked foods like meat, vegetables, cereals, and fruits that one would normally eat in classic meals.

Would this decrease of work done by teeth and digestion system have positive or negative health effects?
