1. Your teeth like “diet” and sugar-free drinks…

The logic is seemingly obvious; if the sugar in drinks is damaging, then the sugar-free version must be fine. Surely you can have as much sugar free lemonade or coke as you want without any ill effects on your teeth?

This one falls heavily into the myth category.

Research at the University of Michigan looked at the damage done to teeth by Coke and Diet Coke. The findings showed that after 14 days’ exposure to teeth, the diet version had done slightly more damage to tooth enamel than the standard version.

Whatever advantages these diet drinks might have in other aspects, saving your enamel is not one of them.

Many sugar free drinks are high in phosphoric acid, citric acid, and/or tartaric acid and it is these acids that can damage the enamel in your teeth; leading to decay and potential cavities or gum problems.

This is even true for fruit juices, which can be high in natural citric acid – while swapping lemonade for orange juice might have many overall health benefits, it is not a switch that removes all potential damage to your teeth. (Tip: Drink your orange juice through a (non-plastic) straw to avoid contact with the teeth)

There are, of course, drinks that do little if any damage to teeth and it will surprise nobody to find that water comes top of that list. However, we appreciate many people do not want to limit themselves to only drinking water.

Tea and coffee are relatively tooth friendly (although staining), and milk is seen as a tooth-safe drink too.

3. Cutting out all sugar is beneficial

If sugar is bad for your dental health a simple equation could follow – reduce sugar, improve dental health, eliminate sugar, enjoy optimal dental health.

The problem with this logic is that dental health is not the only aspect of your health that needs to be considered (even if it is what we tend to focus on across these pages). There needs to be a holistic approach to your diet and health.

Yes, cutting out refined sugars such as those in sweets is recommended, but not the “natural” sugars fructose and lactose that you find in fruits and dairy.

Food with natural sugars contain other important nutrients that help stabilize your blood sugar levels and benefit your overall health.

The glucose in refined sugars is broken down in the mouth, resulting in those nasty acids we mentioned previously, whereas fructose and lactose is broken down in your stomach (that doesn’t mean that you should not brush after eating natural sugars as leaving those deposits on your teeth can still do damage).

To minimize the impact of the sugars and acids in food containing natural sugars, maintain a good oral health routine at home and see your dentist and hygienist as often as they recommend.

5. Sugar is the worst thing for your teeth

While sugar is undeniably damaging to teeth in the long run, frequent and excessive consumption leading to plaque build-up, bacteria and all sorts of dental problems, it is best not to think in terms of one item being the overall worst for teeth.

As mentioned above, the acid in foods and drink can be just as damaging, if not more.

Alcohol also contains sugar and goes even further on the damage scale in that it can dry out the mouth, potentially leading to a buildup of plaque and bacteria which increases the risk of tooth decay and gum disease.

What’s the truth?

The key is to reduce or cut out refined sugars, and to stick to a thorough oral hygiene routine at home – this includes tricks like brushing your teeth before eating in the morning, spitting out your toothpaste but not rinsing with water to keep the protective fluoride on your teeth, and sipping water throughout the day to keep saliva levels at an optimal level.

Regular dental check-ups and oral hygiene appointments should also be maintained to ensure any issues are caught early and to give you that extra boost in cleaning your teeth that you can’t get at home (especially when you’ve indulged in some naughty treats).
