Myth: Only Sugar Causes Tooth Decay [ video ]


– Hi, it’s Dr. Shehan from Dentists of Ivanhoe, and I want to bust the myth that only sugar causes tooth decay.

It’s true, sugar is the main cause of decay. But there are other causes that I want you to be aware of, namely, acidic food and drink. Now acid can either come from outside of the body or inside of the body.

So outside, you’re talking about your citrus fruit, your sparkling water, lemon water, wine, that sort of thing. And when we’re talking about within the body, you’re really talking about vomiting and reflux. All acidic food and drink will cause harm and damage to your teeth.

Other causes are a dry mouth. Saliva acts as a great protector for your teeth, so if you’re dehydrated all the time or if you’ve got a dry mouth, that will have a big impact on tooth decay. Lack of good food for your teeth as well, dairy food, cheese, sugar free yoghurt, they’re really good for your teeth, they prevent tooth decay. Also leafy greens like kale and spinach are really high in calcium so that’s a really good source of calcium, and also eating a lot of fish. They actually, eating a lot of fish will help you absorb the calcium that you eat, that you get from other foods.

Fluoride is a really big thing, so if you don’t have enough fluoride protecting your teeth, so the fluoride will come from your water. So if you’re drinking a lot of bottled water or if you’re using fluoride-free toothpaste, you’re at a higher risk of tooth decay. And for lastly, but finally, it is having a poor oral hygiene. So if you don’t brush your teeth as well, you are at higher risk of getting tooth decay.
