You check the label. Low sugar. Natural ingredients. Sounds healthy, right?
But even the drinks marketed as "good for you"—like kombucha, sparkling water, or cold-pressed juice—can quietly harm your teeth.
The issue isn’t always sugar. It’s acid.
Tooth enamel starts dissolving when exposed to drinks with a pH below 5.7. Even dentine, the layer underneath, breaks down below 6.3.
“People were trying to make the right choices—eating well, exercising—but their teeth were still wearing away,” said Dr Angie Lang.
Acid erosion doesn’t happen overnight. It builds up slowly with every sip. The result? Worn enamel, increased sensitivity, yellowing, and eventually decay.
And it’s not just energy drinks or soft drinks to blame. Even "clean" drinks like lemon water and apple cider vinegar can be too acidic for daily sipping.

Hear how a simple patient question sparked a world-first solution for oral health.
Signs Your Drink Is Doing Damage
Some warning signs include:
- Increased sensitivity to cold or sweet foods
- Discolouration or yellowing teeth
- Rounded or translucent edges
- Enamel that feels rough or thin
If you sip on acidic drinks throughout the day, your teeth don’t get a chance to recover. Saliva can only do so much.
“I’d tell my patients to stop drinking acidic drinks, and they’d ask, ‘Well, what can I have then?’” said Dr Lang. “And I realised—we don’t have an answer.”
Water was the only safe recommendation. But it wasn’t enough to meet people’s needs—especially those with dry mouth, dental appliances, or limited access to regular oral care.
The Safer Alternative
SmileSip was created to give people a better option—one that wouldn’t erode their teeth, but would still taste good and support oral health.
It’s sugar-free, pH-neutral, and designed to work long after you finish drinking it. SmileSip offers:
- Dry mouth relief
- A smoother, cleaner mouthfeel
- Stain prevention
- Science-backed ingredients like xylitol, prebiotics, and botanicals
- Support for a healthy oral microbiome
“If we can stop the damage before it starts, we’re changing the whole conversation about dental care,” said Dr Lang.
What You Can Do
If you regularly drink anything other than plain water, consider these small changes:
- Drink acidic beverages through a straw
- Rinse with water after drinking
- Don’t sip slowly over long periods
- Wait 30–60 minutes before brushing if you’ve had something acidic
- Switch to a pH-neutral drink like SmileSip
SmileSip is easy to use—just mix a sachet into water and sip like any other drink. It fits into daily routines, supports your oral health, and is safe for all ages.
“You don’t need to give up your routine—just swap one thing out for something that’s better for your teeth,” said Dr Lang.
SmileSip is available online and in Woolworths. It’s backed by science and recommended by dentists.
