In America, medical professionals are trading in their spartan clinics for something a little more soothing and sensual.

Lana Rozenberg has transformed her dental clinic in New York's Upper East Side into a Dental Day Spa.

Flowers have replaced the smell of disinfectant and her patients hear the sound of music instead of dental drills.

There are candles scattered across the waiting room. Patients are also treated to a massage and a herbal eye compress as part of the regular check up.

"We wanted to change the sights, sounds and smells of a regular dental office. Our aim was to make the whole experience more comfortable and less stressful. Our patients get to enjoy the comforts of a spa but also get all the necessary treatment of a regular dental visit," she said.

Lana Rozenberg believes her spa is the future. She's not alone in discovering that mixing beauty with health care is good for business.

With the beauty business booming, increasing numbers of medical professionals are abandoning their traditional practices for cosmetic medicine.

In Manhattan, there is no shortage of customers. With many working women leading busy, stressful lives, the idea of a one-stop beauty shop has big appeal.

'Burnout'

Dr Lynn Dormer runs the Dormer Medical Spa in Manhattan. She was a high flying doctor, specializing in critical care. But she gave up her medical career.

Instead of treating people in the emergency room, she makes her patients look beautiful instead.

"In critical care, there's a high burnout rate among doctors. Dealing with insurance companies, long hours and high stress made me realize it wasn't worth it anymore.

"Now, I can spend more time with my patients. I treat people from all walks of life and it's much more fulfilling.�

Thanks to new treatments like Botox, there�s also money to be made. It�s one of the fastest growing businesses in America. A recent survey suggested that 70% of US doctors were interested in setting up these medical spas.

There are no official figures on how many medical spas there are in the United States. But observers here sense that a beauty gold rush is underway.

"This is the new frontier in medicine", said Dr Dormer.

"It's all about wellness. Sure, you can make quite a bit of money in a short amount of time, but the business is becoming more and more competitive so you have to be good at it."
