Глаголы движения

Okay, so my class is finally at the point where we are beginning our steady spiral down into the world of verbs of motion, and it looks to be a rather interesting journey. However, I've already run across a small stumbling block that I hope the community here might be able to shed some light on.

Today my instructor outlined some different instances in which the unidirectional, multidirectional, and perfective forms are used. Most are pretty straightforward and understandable to me, but one use is a little confusing: the future tense of unidirectional verbs in non-idiomatic expressions (e.g. "Завтра я иду к зубному врачу."). Aside from trying to remember not to use быть before the infinitive, I'm having trouble understanding the difference between that usage and the perfective future tense. In our text, my teacher noted that using a unidirectional verb in the future tense without быть places emphasis on the destination, but failed to note how this differs from the perfective future tense (e.g. "Завтра я пойду к зубному врачу."). Does it place emphasis on the act of going to the destination? If someone could clear up when to use one and when to use the other it would be greatly appreciated.

Спасибо!

«Ой, как зуб разболелся! Завтра пойду к дантисту.»
'Gee, my tooth really started to hurt! I'll go to a dentist tomorrow.'
«Нет, я не смогу с тобой пойти в кино завтра. Я иду к дантисту.»
'No, I won't be able to go with you to the cinema tomorrow. I'm going to the dentist.'

I'm a native speaker too. And in my opinion this example is very good =)
