A dentist has warned against a popular health drink that many people believe to be beneficial but could be harming their teeth. Lemon water, often praised for its detoxifying properties and vitamin C content, is widely consumed among health enthusiasts and social media influencers.
However, according to Dr Andrej Bozic, an oral surgeon at Dentum, the high acidity of lemon water poses a significant risk to dental health. "Lemon juice has a pH level of around 2, which is very acidic," explains Dr Bozic. "This acidity can erode the enamel on your teeth, which is the hard, protective outer layer."
Enamel erosion is irreversible and can lead to a host of dental problems, including tooth decay and increased sensitivity. Dr Bozic said: "Once the enamel is worn away, it doesn't grow back. Your teeth become more vulnerable to cavities and damage."
The enamel on your teeth acts as a shield against harmful bacteria and substances. When it erodes, the softer, more vulnerable layer beneath, known as dentin, is exposed. This can lead to:
Increased sensitivity : "People often experience heightened sensitivity to hot and cold foods and drinks when their enamel is eroded," Dr Bozic said.
Christmas trees should be eaten rather than thrown away, say chefs
Higher risk of cavities : "With less protection, your teeth are more susceptible to decay," he added.
Aesthetic concerns : "Eroded enamel can also lead to discolouration and a yellowish appearance of teeth," warned Dr Bozic.
How lemon water can cause damage
Many people enjoy starting their day with a glass of lemon water, believing it's a healthy habit. However, drinking lemon water regularly can expose your teeth to prolonged acid exposure.
"The frequency and duration of exposure are key factors in enamel erosion," Dr Bozic points out. "Sipping on lemon water throughout the day or letting it linger in your mouth can amplify the damage."
You don't have to give up lemon water, but it's important to be aware of its effects on your teeth. "Using a straw can reduce the contact between the acidic lemon water and your teeth, helping to prevent enamel erosion," Dr Bozic said. He also recommends rinsing your mouth with water afterwards to neutralise the acid and wash away any residual acidity.
He added: "Avoid brushing immediately after drinking lemon water; wait at least 30 minutes to allow the enamel to re-harden."
He also advises limiting your intake to once a day to reduce acid exposure. "Consider less acidic alternatives like cucumber or mint-infused water, which are refreshing and gentler on your teeth," he suggests.
Using fluoride toothpaste is another protective measure. "Fluoride helps strengthen your enamel and provides extra protection against acid erosion," Dr Bozic said.
