Why is Sugar Bad for Teeth?
Sugar is harmful to teeth because it causes cavities and accelerates tooth decay. That isn’t an old wives’ tale, and it’s based on more than enough scientific evidence. Keep reading to learn how excessive sugar consumption has harmful effects on the teeth.
Sugar feeds the bacteria present in our mouths. These bacteria produce an acidic substance that demineralizes the enamel on our teeth. Without enamel, the sensitive dentine beneath is exposed to the elements. Dentine is filled with a pulpy collection of nerves that must be protected by enamel. Thus, cavities cause sensitivity or “toothaches”.
Saliva protects our enamel and aids in the remineralization process. Enamel is essential because it protects our dentin, but it is a fluctuating shroud. This crystalline shelter is both decaying and repairable. The calcium and phosphate ions naturally found in saliva fill in the voids left by acidic bacteria.
If a mouth is saturated with sugar-rich saliva, such as after sipping soda or juice, this process is deterred.
Plaque is Wack
Bacteria attach themselves to the tooth’s surface by converting sugar into a sticky, glue-like material. Deposits of this sticky substance is otherwise known as plaque. Saliva can’t replenish enamel hidden beneath plaque deposits. If this buildup collects along the gum line, it causes gingivitis.
Bacteria quickly turns sugar into acid, and plaque can hold acid in contact with the tooth surface for up to two hours before it’s neutralized by saliva. If this process is repeated long-term, cavities are sure to develop.
Mindful Consumption is Key
The World Health Organization suggests we limit our sugar consumption to less than six teaspoons per day. That means our daily limit is 25 grams of sugar. Keep in mind that the average can of soda contains ten teaspoons of sugar- about 40 grams.
Snacks like whole yogurt and fruits are low in sugar, taste sweet, and can satisfy sugar cravings. It’s preferable to go without sugar for a period of a few days to acclimate your taste buds to natural sugars.
