The Spurs midfielder has been sidelined with a hip problem for four games but his manager is hopeful he can return to action in the coming weeks.
Dembele picked up the problem whilst on international duty with Belgium, and he has missed Spurs' last four games; however, Villas-Boas is confident the injury is not too serious and that he can have his summer signing back in action sooner rather than later.
"We want to avoid surgery if we can," Villas-Boas told reporters. "If there happens to be surgery, I think we are looking for one month, one month and a half. Hopefully that will not happen because we have some good indications the player will be back in one week or two weeks."
Dembele has scored once in seven games with Tottenham since joining the club from Fulham during this summer's transfer window. finding the back of the net in his debut with the team against Norwich City on Sept. 1.
