The health benefits of Saliva… Saliva isn’t just a watery substance in the mouth it actually has many health benefits, one being that it helps to protect our teeth. Saliva contains polin, this is a protein in which safe guards tooth enamel, containing minerals it also helps the remineralization process aiding our teeth. Not to mention without it we would find it very difficult to budge those stray pieces of food we all end up with at some point between the teeth. Saliva also contains antibacterial properties in which help to prevent bacteria build up in the mouth, it also contains antimicrobial/ antibodies compounds. I am sure you will have noticed at some point or other that wounds within the mouth heal much faster than exterior wounds this is due to the amount of protein present in our saliva, protein helps to form new blood vessels. You will often find animals licking their wounds and this is why! Although saliva has many brilliant health benefits it can also be deadly… exchanging saliva (kissing) can also pass the deadly virus HIV.
