Jane Fonda has admitted spending several thousand dollars on cosmetic dentistry as part of her bid to preserve her good looks.

The 73-year-old actress said in an interview with the Daily Mail that she paid $55,000 (£34,100) for a new set of teeth.

Fonda, who has won two Oscars during her screen career, suggested that having money is one of the secrets to looking good in old age.

"It was the teeth or a new car – and I opted for the teeth," she remarked, adding: "It costs a lot to look the way I do."

A healthy sex life has also helped, she remarked, but noted part of success is due to her genes, which she said "cost nothing".

Fonda recently showed off her cosmetic dentistry during the Cannes Film Festival, where she made an appearance to promote her new film Peace, Love & Misunderstanding, which is due out later this year.
