Scott Johnson's men crashed to a painful 28-0 loss against the Springboks at Murrayfield on Sunday.
It was the worst result of the Australian interim head coach's 11-month tenure and dented confidence just as it was starting to return following the dismal Andy Robinson era.
The Wallabies are next up for the Scots in the final Autumn international but they will be considerably weakened after dropping five players involved in a late-night drinking session.
But even with that in mind, Edinburgh number eight Denton has warned his team-mates they cannot feel sorry for themselves against Southern Hemisphere opposition.
He told Press Association Sport: "We have got no time to be demoralised. We play Australia on Saturday and we have to be ready.
"We were straight back into meetings on Monday and we just need to move on for that next game.
"We're all disappointed with Sunday but there is nothing we can do and we just have to get on with things.
"If we don't, we will just end up on the end of another poor result."
South Africa by-passed feeble Scottish defences three times to score in a bruising opening half in Edinburgh before completing the rout with a fourth try after the break.
Two of the Boks' touchdowns came from powerful line-out drives and Denton admitted his side lost the physical battle.
"It was massively disappointing," he said. "We didn't play as well as we could and we lost the breakdown battle.
"We knew what was coming. We knew that they were going to try and maul us and that it would be a physical battle.
"But they did well to be fair. For the first maul that led to their opening try, we all piled in and all they did was go round the side. It was intelligent rugby.
"There is no question they are a good side and we have to be at out best to beat them.
"We are more than capable of that. We showed in South Africa that we can match their brutality, their physicality.
"I think that is what will win Test matches these days. If you are the more physical team at the breakdown, the more accurate, you will win matches."
The Scots managed to contain the visitors in the final half and hour against the Springboks as they stemmed the flow of points and Denton says they deserve credit for that.
"After their last try we showed a lot of character - that's important," he said.
"If you are going to create a winning team you need to have that pride in the jersey. There is no question of the pride in the Scottish team because we are all very proud people.
"But how this team differs is that when our backs were against the wall, 28-0 down in a situation where a lot of other teams would have folded, we did well to keep playing."
