Many people drink lemon water as part of their daily routine. It has been touted as a health drink with various benefits, such as aiding in digestion, boosting immunity, and promoting weight loss. However, there are concerns about the effects of lemon water on teeth. It can damage tooth enamel and dentin, and cause dental sensitivity.
The truth is that lemon water can have both positive and negative effects on teeth, depending on how it is consumed. On one hand, the vitamin C found in lemons can help fight bacteria in the mouth and promote healthy gums. However, the high acidity of lemon juice can erode tooth enamel and dentin if consumed in excess or sipped frequently throughout the day.
To minimize potential harm, it’s advisable to drink lemon water through a straw and rinse your mouth with plain water afterward to protect your teeth. Balancing the benefits and risks is key to enjoying lemon water while maintaining oral health.
How Lemon Water Affects Teeth
Lemon is a highly acidic fruit with a pH level of around 2-3 (pH level is measured from 1–14 with the lower numbers being more acidic). This acidity can cause erosion of tooth enamel, which is the protective outer layer of our teeth. When the enamel wears down, this exposes the inner layers of the tooth, which are more sensitive and prone to damage. Tooth erosion can lead to various oral health issues such as tooth sensitivity, discolouration, decay, and even tooth loss.
When we mention discolouration it can be a dramatic change in tooth colour to yellow, because you are eroding the white enamel layer, exposing the yellow dentin layer inside the tooth. This discolouring cannot be corrected with whitening—only veneers.
When you drink plain lemon water (lemon juice mixed with water), the acidity level is diluted, and therefore it’s less harmful to teeth. However, some people prefer to drink warm lemon water or add honey for sweetness. Warm lemon water is more acidic than cold lemon water, making it more damaging to tooth enamel. Similarly, adding honey increases the sugar content of the drink, which can contribute to tooth decay.
Another factor that determines how lemon water affects teeth is frequency of consumption. Sipping on lemon water throughout the day exposes teeth repeatedly to acid, increasing the risk of erosion. It’s better to consume lemon water in one sitting rather than sipping on it slowly over an extended period.
Tips for Protecting Your Teeth
If you enjoy drinking lemon water and want to maintain good oral health, there are a few precautions you can take. Here are some tips to protect your teeth from the potential harm of lemon water:
- Limit frequency of consumption: As mentioned earlier, frequent exposure to acidic drinks can damage teeth. It’s best to limit how often you drink lemon water and consume it in one sitting rather than sipping on it throughout the day.
- Use a straw: When you drink lemon water through a straw, it bypasses the teeth and minimizes contact with the acidic liquid. This reduces the risk of tooth erosion.
- Rinse with plain water: After drinking lemon water, rinse your mouth with plain water to help neutralize any remaining acid.
- Don’t brush right after drinking: Acidic drinks weaken tooth enamel, so it’s best not to brush immediately after consuming lemon water. Wait at least 30 minutes before brushing your teeth to give your saliva time to neutralize the acid.
- Consider drinking through a meal: Consuming lemon water with a meal can help reduce its damaging effects. Food acts as a buffer and helps neutralize the acid in the drink.
- Use fluoride toothpaste: Fluoride is known for its protective properties against tooth decay. Using a fluoride toothpaste can help strengthen your teeth and protect them from acid erosion.
- Stay hydrated: Drinking enough water can help balance the pH levels in your mouth and neutralize any acid from lemon water. Plus, drinking plenty of water has a number of other attractive health benefits.
- Consider alternatives: If you want the health benefits of drinking lemon water but are concerned about its effect on your teeth, consider adding a slice of cucumber or mint leaves for flavor instead. These options are less acidic and can still provide some added nutrients.
- Visit your dentist regularly: Regular dental check-ups are crucial for maintaining good oral health. Your dentist can monitor any signs of acid erosion on your teeth and provide personalized advice on how to protect them.
