The 27-year-old endured a tough time with a hamstring injury last season at Bath and has decided to make a fresh start with Worcester, despite having a season left on his deal at the The Rec.
With head coach Gregor Townsend now taking the reins with Scotland, Denton is hoping he can add to his 35 caps in the future, having last played international rugby in last summer's tour of Japan.
He told The Scotsman: "First and foremost I just want to get back to enjoying my rugby, playing regularly for Worcester and making an impact for them, but of course Scotland is on my mind because I love playing for my country.
"Running out at BT Murrayfield for a big international is a special feeling and it was strange watching the guys play in the Six Nations and on the summer tour without me.
"My lack of rugby towards the end of last season cost me in terms of the summer tour, but Gregor and Matt (Taylor) have been great at keeping in touch and letting me know I am still in their thoughts. It is now up to me to prove that I deserve to get back to that level."
Denton will be hoping to make Townsend's next squad to face Samoa, Australia and New Zealand in November.
