Tooth is chipped. should i get it fixed?

Up to you: If the chip occured because you have a cavity in the vicinity, then the cavity will progress and you will eventually need root canal therapy. If the chip is just from trauma and there is no decay, then restore it or have it smoothed down. Since you can't tell if there is decay, it's best to have a dentist look at it.

Yes: Depending on location and extent, simply smoothing the area may be all you need. Have it evaluated, because seemingly small chips can actually be due to decay in the area which has weakened the enamel. It's always easier to deal with problems early and when they are small.
