Does Gum Receding reverse?

I noticed quite recently that two of my front teeth have receding gums! I researched and found out why and its because I have been brushing them too hard!

my gums look very healthy and so do my teeth but two of the front teeth (the bottom canine and the one beside it have receded due to hard brushing! can this be reversed and can anyone advise me if it will naturally heal back by itself if I go gentle and how long should it take?

thanks
