How Can I Resolve A Cheek Dent After Stitches Were Removed?

I took a hit on my face, and had 2 stitches outside my left cheek and 6 inside. My face was all normal until I removed the 2 stitches on the outside. Now I have a dent on my cheek that is really bothering me.My doctor suggested me to use Contractubex and I have been using it for 20 days. I was told that only a very small dimple shall remain after 3-4 months, but I am not convinced. Is it possible to get rid or atleast minimise the dent without sugery. I massage the inside of cheek twice daily.
