The Drinks Your Hygienist Wants You to Rethink
How everyday drinks affect your teeth – and simple swaps that make a difference
If you’ve ever been told you need fewer fizzy drinks, you’re not alone. But sugar isn’t the only thing your dental hygienist is looking at.
Many of the drinks we reach for every day – from fruit smoothies to sports drinks – can contribute to tooth decay, enamel erosion and staining. The good news? You don’t have to give up everything you enjoy. A few simple swaps can make a real difference to your oral health.
At Hello Dental, we believe prevention is always better than treatment. Here’s what your hygienist wishes more people knew about what’s in their favourite drinks.
The biggest culprits
Fizzy drinks
Whether they’re full sugar or diet, fizzy drinks are tough on teeth.
A standard 330ml can of cola contains around 35g of sugar – that’s almost nine teaspoons. Even sugar-free versions are highly acidic, which can gradually wear away enamel.
Better choice: Sparkling water with fresh lemon or lime occasionally, or still water for everyday hydration.
Energy drinks
Popular brands such as Monster and Red Bull are often packed with sugar and acids.
A 500ml can of Monster Original contains around 55g of sugar, while even sugar-free energy drinks remain acidic enough to soften enamel.
Better choice: Unsweetened iced coffee, plain coffee or water if you need a boost.
Fruit juice
Orange juice sounds healthy because it contains vitamins, but it’s naturally high in sugar and acid.
A 250ml glass of orange juice contains around 20-22g of sugar.
Because it’s a liquid, the sugar coats your teeth quickly, while the acidity can weaken enamel.
Better choice: Eat the whole fruit instead. You get the fibre, feel fuller and your teeth are exposed to less sugar all at once.
Smoothies
Many shop-bought smoothies contain the equivalent of several portions of fruit blended together.
A 250ml smoothie can contain 20-30g of sugar, depending on the ingredients.
Although much of this is naturally occurring sugar, your teeth don’t know the difference.
Better choice: Homemade smoothies with vegetables, unsweetened yoghurt and fewer fruits, enjoyed with a meal rather than sipped throughout the day.
Sports drinks
Designed for endurance athletes, sports drinks aren’t usually necessary after a quick gym session.
A 500ml bottle may contain around 30g of sugar, alongside acids that can increase enamel wear.
Better choice: Water is usually all you need for exercise lasting under an hour.
Flavoured coffees
Your favourite caramel latte could contain more sugar than a chocolate bar.
A large flavoured coffee from a high street coffee shop can contain 25-40g of sugar, depending on the syrups and toppings.
Better choice: A regular latte or cappuccino without syrup, or ask for fewer pumps of flavouring.
Bubble tea
Bubble tea has become increasingly popular across the UK, but it can be surprisingly sugary.
A regular serving often contains 30-50g of sugar, especially when sweetened tea, flavoured syrups and tapioca pearls are combined.
Better choice: Choose reduced sugar options or fruit tea without added syrups.
What about alcohol?
Some alcoholic drinks also deserve attention.
Cocktails often contain sugary mixers, while cider and alcopops can be surprisingly high in sugar. White wine is acidic, and red wine is well known for staining teeth.
Alternating alcoholic drinks with water helps reduce both dehydration and the amount of time sugars and acids stay in contact with your teeth.
It’s not just what you drink—it’s how you drink it
Sipping sugary or acidic drinks over several hours keeps your teeth under constant attack.
Instead:
- Drink sugary drinks with meals where possible.
- Avoid sipping throughout the day.
- Use a straw when appropriate to reduce contact with teeth.
- Wait around 30 minutes before brushing after acidic drinks to allow enamel to recover.
- Finish with water to help rinse your mouth.

Your hygienist’s favourites are refreshingly simple:
- Water
- Milk
- Unsweetened tea
- Coffee without added sugar
- Sugar-free drinks only occasionally, as they can still be acidic
Looking after your smile
Regular hygiene appointments do much more than polish your teeth. They help remove plaque and tartar, identify early signs of gum disease and give you personalised advice based on your daily habits.
Sometimes, small changes—like switching just one daily drink—can reduce your risk of tooth decay over time.
If you’re looking for a dentist in Colchester, the friendly team at Hello Dental is here to help you keep your smile healthy with practical, judgement-free advice and preventive care.
