A dental health expert has urged people not to let their dogs kiss them. Kissing on the mouth is a natural behaviour for dogs - often indicating a sign of affection.
But Dr Khaled Kasem, dental expert and chief orthodontist at Impress, said the action could be damaging your oral health. Dr Kasem said: "Dogs aren't known for their hygiene. They don't (usually) brush their teeth or rinse with mouthwash, and they've probably never visited a dentist.
"Their daily routine consists of eating leftovers on the floor, licking their bum, and checking out dead animals left on the pavement. Ultimately, their mouth is filthy.
"Such activities result in a build-up of bacteria in your dog's mouth, and although the majority is probably harmless, they can pick up parasites and bacteria that can make humans ill. Whether they've drunk contaminated water or sniffed animal waste, these bacteria will not boost your immune health as some have argued.
"Not only can human infection with pet parasites cause a wealth of intestinal diseases, but it also transfers damaging bacteria to your teeth and gums, causing gum disease. Severe gum disease can affect the tissues that support teeth and holds them in place.
"If left untreated, the jawbone can decay, opening up spaces in between the gums and teeth – resulting in tooth loss. Other common infections that dogs can transfer include salmonella, ringworm, and hookworm."
Dr Kasem said while the occasional dog kiss is "fine", she would not recommend making it a "regular occurrence". Dr Kasem added: "Not only are you risking your health, but you've heard of the term dog breath, so would you really want the same?
"Think about the ingredients in their food and what that might taste like in your mouth - gross! If your furry pal does give you a kiss, make sure to brush and floss straight away to remove any bacteria and try to discourage the behaviour in the future."
