Is Lemon Water Bad for Your Teeth? What You Need to Know
Lemon water has always had a reputable place in health and wellness teachings. Bloggers often rave about lemon infused water being their morning ritual and it is a simple and refreshing pick-me-up throughout the day for anyone. Hydrating, detoxifying and loaded with vitamin C, the question is what doesn’t lemon water do?
But can this be true when it comes to dental health? Let’s find out.
The Benefits of Lemon Water (Just Not for Teeth)
There’s no doubt that lemon water comes with a bunch of health perks. Many find the citrusy twist to make plain water more enjoyable, encouraging better hydration throughout the day. Being a natural source of vitamin C means it plays a key role in supporting immunity and maintaining healthy skin. Not just taken independently, even doctors recommend lemon water to aid in countless ways. Some people swear by a glass of lemon water first thing in the morning to help stimulate digestion, while others believe it has an alkalising effect in the body after digestion, despite its naturally acidic nature. All in all, it’s a simple habit for some, but when it comes to your teeth, it’s not quite so harmless.
Why Lemon Water Can Be Bad for Your Teeth
Despite its nutritional benefits, lemon water can pose a risk to your teeth due to one key factor. Two words: Acid Erosion.
1. Acid Weakens Tooth Enamel
Lemons contain citric acid, which has a very low pH. Enamel, the protective outer layer of your teeth, is strong but it’s not invincible. When it comes into frequent contact with acid, enamel begins to soften and erode. This thinning leads to increased sensitivity, discolouration and even cavities.
To put it in perspective:
- Pure lemon juice has a pH of around 2.
- Tooth enamel begins to demineralise when exposed to pH levels below 5.5.
Even when diluted in water, lemon juice remains acidic enough to do damage with repeated exposure.
2. Sipping Throughout the Day Makes It Worse
It’s not just what you drink — it’s how often you drink it. If you’re sipping lemon water slowly over several hours or multiple times a day, your teeth are under constant acid attack. Unlike a quick meal or a one-time drink, this keeps your mouth in an acidic state for longer periods.
3. Tooth Sensitivity and Discomfort
Eroded enamel exposes the softer dentine underneath, which houses tiny nerve endings. This can lead to heightened tooth sensitivity, especially when eating or drinking hot, cold, or sweet things.
Signs That Your Teeth Might Be Affected
If you’re a regular lemon water drinker, look out for these symptoms:
- Tooth sensitivity to cold or sweet foods
- Yellowing teeth, as thinning enamel exposes the darker dentine layer
- Rough or uneven tooth edges
- Increased risk of cavities or decay near the gumline
These signs don’t appear overnight but they do build up with continued acid exposure, especially if other habits like brushing too soon after drinking lemon water come into play as it drives it in deeper for more abrasive damage.
Tips to Enjoy Lemon Water Safely
If giving up lemon water entirely isn’t your style (and for many, it’s not), the good news is you don’t have to. A few smart tweaks can help you enjoy the benefits without compromising your dental health.
1. Drinking through a straw can reduce direct contact between lemon water and your teeth. It’s a simple switch that makes a big difference over time.
2. After drinking lemon water, rinse your mouth with plain water to help neutralise acids and flush them away.
3. It might seem like a good idea to brush straight after acidic drinks, but brushing too soon can actually do more harm. Acid softens enamel, and brushing during this softened state can wear it down even faster. Wait at least 30 minutes before doing so.
4. Instead of sipping lemon water slowly for hours, try finishing it in one sitting. This limits the time your teeth are exposed to acid and gives your saliva a chance to do its job of neutralising the mouth’s pH and re-hardening enamel.
5. A splash of lemon in a large glass of water is much safer than lemon juice that’s heavily concentrated. Try using just a few drops in a big glass of water, and your teeth will thank you. Chances are your taste buds will still get that refreshing citrus hit.
6. If you’re really concerned about acidity, adding a tiny pinch of baking soda can help neutralise the pH. But make sure not to overdo it since baking soda is abrasive and should be used sparingly.
7. If lemon water is part of your regular routine, mention it at your next dental appointment at SDG Dental. Our dentist can look out for early signs of enamel erosion and suggest additional protective measures like fluoride treatments or remineralising toothpaste.
Balance Is Key
So, is lemon water bad for your teeth? It can be — but only if you’re not careful.
Like many things in health, it’s about balance. Lemon water doesn’t have to be banned from your routine, but it should be enjoyed mindfully. Take the steps to reduce acid exposure, protect your enamel and give your mouth time to recover between drinks.
With a few tweaks to your habits, you can keep your teeth strong and enjoy your morning citrus fix guilt-free.
