DAVID Reynolds was bothered by his angular jaw, especially when people told him he had put on weight.

But the 51-year old IT coordinator, of Burton near Christchurch, was suffering from a common problem – grinding and clenching his teeth at night.

The condition, often brought on by stress, is known as bruxism, or temporo-mandibular disorder (TMD), and in David’s case, it had caused his jaw muscles to become overdeveloped.

He spotted a newspaper article about a new Botox procedure created by Dr Bob Khanna, a top aesthetic practitioner and celebrity favourite.

“I was fed up of being told I had put on weight by friends and colleagues so I immediately took the article to my dentist to get his advice,” said David.

“He explained that the botox would weaken the muscle, meaning that subconsciously I wouldn’t have the energy to crunch and grind my teeth during the night. My muscle would shrink and face would look slimmer again.

“I was delighted that Dr. Khanna could offer me a combination of botox and dermal fillers to help me achieve a tapered, slimmer face shape. Without hesitation I accepted and I can’t put into words what a difference it has made.

“My face is slimmer and I recognise the person that I see in the mirror again. I prefer people telling me that I look like I’ve lost weight than gained, but my weight has remained the same throughout.”

Dr Khanna said the Dr BK Botox Lift took only five minutes and resulted in a slimmer looking jaw and enhanced cheekbones after about six weeks following the treatment.

“Grinding and clenching of teeth during sleep can change the shape of the jawline and lead to an angular effect,” he explained.

“A few simple procedures can dramatically change the shape of the face to soften and make it more slim line. In David's case, it’s been a fantastic result and the changes quite dramatic.”

Dentist Dr Khanna has been using botox and dermal fillers for more than 12 years and has featured in a number of television documentaries, including Channel Five’s Cosmetic Surgery Live, BBC’s Ruby Wax Show and Discovery Health’s Silicone Chicks.

People may not realise they are clenching and grinding their teeth at night, but dentists can often spot the resulting damage to the teeth. Symptoms can include waking up with pain and lightness on the sides of the face.
