Dr. Peter Gorden, dental advisor at the British Dental Association, says, “After eating, your mouth is full of sugar solution and acidic saliva, which causes plaque build up...It stimulates saliva flow and brings plaque levels down to normal.”
Releases tension
A passionate kiss is a great relaxation technique, says stress consultant Michelle Kay McNabb. "When your mouth is in a kissing position, you are almost smiling and as our emotions and body language are so closely linked, it's almost impossible to smile and feel tense at the same time," she explains. "Also, your breathing becomes deeper and your eyes close when you kiss. That's what you do when you relax. It's a perfect way to shut out the world."
Aids in weight loss
You need to use 3,000 calories to lose one pound. Claire Potter, fitness consultant for Cosmo magazine, says that "a long kiss makes the metabolism burn up sugar faster than usual. The calories burned depend on the intensity, but you can rely on 10 calories for every 10 minutes." That means that you can lose one pound by kissing for five hours.
Slows the aging process
"Kissing helps to tone your cheek and jaw muscles, so they're less likely to sag,".
Increases fitness
“Your heart is pumping, your pulse is racing... If kissing is exciting, you release adrenaline into the bloodstream and your heart pumps more blood around your body,"It's a great cardiovascular workout."
Finds "The One"
Kissing someone releases pheromones, the chemical messengers that signal sexual attraction. "The first kiss is always a good way to work out if there's any chemistry between you," says Paul Brown, sexual and marital therapist. "In humans, it's thought that smells play a vital part in subconscious attraction, and if your pheromones aren't 'in tune', you're unlikely to hit it off."
Boosts your self-esteem
"In theory, when you're kissing, you're happy. And when you're happy, you feel good about yourself,"
