We all know that sugar is bad for your teeth, but why? How does sugar cause decay?
Let’s see how sugar helps the bacteria in your mouth.
Sugar + bacteria= acid.
Sugar is a relatively new addition to our diets. It provides us with a lot of quick energy. The bacteria on our teeth can also use sugars to grow and creates acid. This acid sitting on our enamel causes the tooth to become weak. This happens every time we eat sugar. Over time, if the tooth is not repairing itself quickly enough, the acid breaks down the tooth faster than the tooth can recover, leading to holes in your teeth.
Once the hole is past the enamel layer, it stops being able to fix itself and needs a filling.
Acid + time = decay
Bacteria get access into your tooth via this hole made by acid. As time goes on, the decay gets larger, getting closer and closer to the nerve.
Sometimes people feel hot, cold, and sweet sensitivity when the decay is small. And other times they don’t feel any pain at all until the nerve is exposed.
The easiest way to stop decay from forming is to limit your daily intake of sugar.
What counts as sugar? There are many different names for sugar:
- corn syrup
- brown sugar
- fructose
- barley malt
- malt syrup
- dextrose
- agave nectar
- cane sugar
- maltose
- beet sugar
- glucose
- fruit juice concentrate
- cane juice
- coconut sugar
- golden syrup
- lactose
When looking at the nutritional information on the back of a packet, look at the Nutritional Information Panel to see the total amount of sugar present. Something labelled ‘no added sugar’ may have a lot of natural sugars! This is how hidden sugar cause decay.
