接吻有益口腔健康

Smooching boosts saliva production and clears the mouth of the bad bacteria and acids that cause decay.

接吻可以促進唾液的分泌，清除口腔中腐蝕牙齒的有害細菌和酸。

Orthodontist Dr Khaled Kasem said people should kiss for four minutes a day on top of brushing and flossing.
正畸醫(yī)生卡里德•卡西姆稱，在刷牙和使用牙線的同時，可以每天接吻四分鐘。

He said: “The main benefit of kissing is that it produces more saliva in your mouth.
他說：“接吻主要好處是促進口腔分泌更多唾液。”

“Saliva neutralizes the acids that sit on your teeth, which helps to reduce your risk of getting tooth decay. It can also wash bacteria off your teeth to reduce stubborn oral plaque.”
“唾液能中和牙齒上的酸，有助于降低蛀牙的風險。還能清潔牙齒上的細菌，減少頑固的牙菌斑。”

A daily snog also reduces infection risk because bacteria from your partner’s saliva boost your immune system — and vice versa.
每天接吻還可以降低感染風險，因為伴侶唾液中的細菌會提高你的免疫力。
