Can I eat ok with 2 molars and no wisdom teeth?

I have only 8 molars left (2 each side top and bottom). I have 3 wisdom teeth but they have fillings in them. At my last visit, the dentist said I had a new cavity in a wisdom tooth and recommended removing it instead of filling it. In fact, she recommended removing all 3 wisdom teeth to avoid a future problem with long roots, further decay, etc. My question is: can I eat well on 2 molars or should I keep the other 2 wisdom teeth as long as possible (since normally I would have 3 molars top and bottom)?
