White lines seen after mosaic

I had converted several polygons to shapefile and merged all the shapefiles using the "mosaic to new raster" function. After merging, there were white lines at the edge of each region. I thought that the "mosaic to new raster" function would smoothen the edge?

How do I remove these lines so that the edges are uniform? I have attached the image here.

As i am still new to this software, I hope that someone can guide me along here. Many many thanks in advance.
