Apart from reaping oral health benefits, Dr Kasem also explained that kissing can boost your immune system.
He said: “Last but not least, the exchange of saliva during a kiss encourages the immune system to create more antibodies, which defends your body from infection.
“Some research shows that we do exchange a lot of bacteria during kissing but this increase of antibodies is in fact a good thing.”
But it’s also worth noting that kissing people who are ill or already have “bad” oral hygiene can lead to “negative impacts”.
