The Shakespeare in Love star, who wants to carry on working into old age, can't understand why families let their loved ones live in care homes and she is adamant she will never end up in such a place.
She tells Saga magazine, "As anyone who's visited one of these homes knows, you just cannot put people into a circle of chairs and have them watching television all day - it's inhumane.
"I don't really want to retire. I intend to go on working as long as I can because I still have a huge amount of energy. I'm certainly not ready to be packed away somewhere and told to put my feet up and go to bed at a certain time."
The 77 year old goes on to urge fans to take care of their older generations, like she did with her parents and in-laws.
She adds, "After my father died and (late husband) Michael (Williams) and I got married, we bought a house in Warwickshire (England) and we and my Ma (mother) and Michael's parents all lived together. It's the way they do things in the Mediterranean countries and, of course, in India, but by the very nature of what it is, it's not easy.
"However, the pluses outweigh the disadvantages by a considerable margin. For example, my daughter Finty now remembers her grandparents very vividly and fondly."
The Shakespeare In Love star became a first-time mother to daughter Finty at the age of 37, and she and late husband Michael Williams longed for another baby.
Dench was unable to fall pregnant again and the couple subsequently looked into adoption, but officials denied their request and the actress admits not having a second child is "the only regret" she holds in life.
She tells Britain's Yours magazine, "I wish we'd had lots more children. That's the only regret I have. But I was older and it didn't happen.
"We tried to adopt a child and they didn't like it because we were over 40 - and Michael was a Catholic and I was a Quaker. It obviously wasn't to be."
Dench also opens up about her early days as a mother in the interview, revealing, "I'd had a daughter and having a family I wanted to be at home. Michael wouldn't let me stop (working), though. So in the beginning I tried to arrange things so I was with her during the day and going to the theatre in the evening when she was in bed. Later on, when she went to school, I could do things like television during the day to be with her in the evening."
The veteran actress starred in the programme - set in a fictional village called Cranford in Cheshire, England - alongside her daughter Finty Williams in 2007 and recently reprised her role for two new Christmas episodes.
And revisiting the set made Dench realise how much she misses the sense of community spirit that she experienced in her youth.
She tells Yours magazine, "It (Cranford) is still the place where people watch out for one another and know each other's business. It takes me back to when I was a little girl in the Thirties and Forties. I remember friends of ours being blitzed (bombed during World War II) in York and everybody rallied round bringing food and clothes, which was wonderful. Now we tend to shy away from that. I'm always rather thrilled that people can't find my house on their Sat Nav (satellite navigation system). But still, there is something to be said for a community that cares."
