Most folks know that soda’s bad for your teeth, but fewer realise that loads of drinks touted as “healthy” can be acidic enough to provoke enamel erosion or trigger heartburn. If you have sensitivity in your teeth, heartburn or digestive discomfort, the drinks you consume every day can make a big difference. In this guide, we’ll look at which non-acidic drinks are kinder to your teeth and stomach, and give some tips on how to bring them into your routine.
- Fluoridated water is normally the best go-to drink for oral health and reflux, as it’s got an almost neutral PH level and has other dental benefits.
- Lots of so-called “healthy” drinks, including flavoured waters, sports drinks, energy drinks and fizzy beverages, are still pretty acidic.
- Good options include plain water, milk, unsweetened plant milk, herbal teas, unsweetened coconut water and plain aloe vera juice.
- Cutting down on acidic drinks can help avoid enamel erosion and may be a bit kinder on your reflux symptoms.
What Makes a Drink Non-Acidic (and Why It Matters)
The pH scale goes from 0 (acidic) to 14 (alkaline), with 7 being right in the middle. Plain tap water usually sits around a pH of 7, while drinks that are below about 5.5 are more likely to erode enamel.
Carbonated or acidic beverages can also give you heartburn or make things worse for you if you’re already getting acid reflux. Since most drinks don’t list their pH, have a look at the ingredients for things like citric acid, phosphoric acid, carbonation, and citrus fruit-flavored, or ‘sour’ flavourings.
When it comes to non-acidic drinks, ones with a pH of 7 are the real deal, while lower-acid options usually fall between about 5.5 and 7.
Milk, Coconut Water, and Aloe Vera Juice: The Top Best Drinks That Are Non Acidic
- Water: The simplest and best choice for staying hydrated and helping with digestion. Fluoridated water also helps to strengthen your tooth enamel.
- Milk and unsweetened plant milk: Dairy milk gives you calcium, while unsweetened almond, soy and oat milk are usually fine options. Don’t get the sweetened ones, though; they often have added sugars.
- Unsweetened coconut water: This one’s got electrolytes and is generally less acidic than citrus juices like orange or lemon. Check the label to make sure it doesn’t contain added citrics.
- Plain aloe vera juice: Unsweetened, food-grade stuff can be used for hydrating and comfort for your digestive system. Choose a purified, decolourised inner-leaf product.
- Drinkable yogurt: Unsweetened kefir or drinkable yogurt can give you calcium and probiotics without the acidity of fruit-based versions.
For the most gentle, right drink choices, keep them plain and unsweetened and avoid adding lemon or citrus flavours.
Herbal Teas and Gentle Hot Drinks
Herbal teas are popular because they’re usually low in acidity and caffeine-free, making them pretty gentle on your teeth and heartburn.
Good options include chamomile, ginger, rooibos, and licorice root tea, but be careful with peppermint tea as it can make things worse for some people’s heartburn by relaxing their lower esophageal sphincter.
For the gentlest option, avoid lemon, citrus, or berry flavourings, and sugar. Let the tea cool down a bit before drinking, as drinks that are too hot can irritate your gums and esophagus.
Non-Acidic Drinks for Acid Reflux and GERD Relief
For acid reflux and GERD, choose drinks that are low acid, non-carbonated, and caffeine-free.
Good options include:
- Plain water
- Low-fat milk or unsweetened plant milk
- Chamomile or ginger tea
- Unsweetened coconut water
- Low acid juices like pear or carrot juice
- Low acid smoothies, like banana with unsweetened almond milk
Avoid citrus juices and fizzy drinks if they make your reflux worse. Keep a drink diary to help figure out what triggers your symptoms. If they come on more than twice a week, talk to your doctor.
Best Non Acidic Drinks for Oral Health
Fluoridated water is the best everyday choice for your teeth; it rinses away acids and food particles and helps to strengthen your tooth enamel.
Other tooth-friendly options include:
- Still, unflavoured water
- Dairy or unsweetened plant milk
- Herbal tea without lemon
- Less acidic vegetable juices
Check the labels carefully; flavoured waters, sports drinks, energy drinks and lots of “vitamin enhanced” beverages contain acids or sugars that can damage your enamel.
Coffee, Sports, and Energy Drinks: Hidden Acids in “Healthy” Beverages
Lots of drinks that are marketed as healthy still have acidic ingredients. Try to limit:
- Flavoured waters: they often have citric or malic acid
- Sports and energy drinks: they combine acids with added sugar and/or caffeine
- Sodas, sparkling water, and seltzers: the carbonation makes carbonic acid, and citrus flavours add more acidity, and yes, plain sparkling water is still mildly acidic.
- Coffee and green tea: naturally acidic, which can give you heartburn or discolor your teeth
Ingredients like citric acid, phosphoric acid, or sour-tasting flavorings are a red flag. Try to go for plain, unsweetened drinks if you can.
Building a Non-Acidic Drink Routine: The Smarter Approach
Don’t aim to cut out acidic drinks or acidic foods completely, just make them a side option. Think of non-acidic drinks as your go-to choice, not a consolation prize.
First Thing in the Morning: Swap in ginger tea, chamomile tea, or, if you’re a die-hard coffee fan, just try to limit your coffee intake to what you can handle.
Throughout the Day: Keep a bottle of water with fluoride in it, and instead of reaching for soda or energy drinks, grab some unsweetened milk or a soothing herbal tea.
When You Eat: Stick to good old water or milk. Try not to hang out over a cup of acidic drink for too long.
At Night: Chamomile or rooibos tea is your best bet, especially if you’re prone to getting heartburn at night.
And if you do want an acidic drink, don’t make it a regular thing. If you do have one, try to have it with a meal, follow it up with some water, and wait at least half an hour before brushing your teeth.
FAQ
Is sparkling water really non-acidic?
Plain sparkling water is mildly acidic but far less harmful than soda. Flavored versions often contain citric acid and are more erosive. If you have sensitive teeth or reflux, still water is safer.
What is the single best drink if I have both acid reflux and oral health concerns?
Fluoridated tap water is usually the best choice because it’s sugar-free, low-acid, and helps protect enamel. Milk and unsweetened plant milks can also be good options.
How can I tell if a drink is acidic without a pH chart?
Look for phosphoric acid, pineapple, orange, or other citrus fruits in the ingredients. Sodas, energy drinks, juices, kombucha, and vinegar-based drinks are usually acidic. When unsure, choose water, milk, or unsweetened herbal tea.
Are sugar-free or diet drinks safe for my teeth and reflux?
Not necessarily. Sugar-free drinks may reduce cavities but can still erode enamel and trigger reflux if they’re acidic. Water, herbal tea, and unsweetened plant milks are safer choices.
How soon will I notice benefits after switching to non-acidic drinks?
Patients notice that Reflux symptoms may improve within days, while protecting enamel and reducing sensitivity takes longer. Consistently choosing non-acidic drinks can benefit both your teeth and digestive comfort over time.
