Its going to take awhile and it's going to be slow if you want to do it right. He might never be as comfortable going to the right as he is to the left but he should make drastic improvements over time. Start with the basics. Walking - then trotting - then a canter. And make sure you warm up going to the left where he is more comfortable and let him end going to the left as well. He needs to build his confidence going to the right and you don't want to overwhelm him.
Thankyou everyone for your help. I'll let you know how it goes.
