Dentist issues warning about popular health drink ‘harming teeth’

A dentist has warned against a popular health drink that many people think is good for them but could be damaging their teeth. Lemon water, often praised for its detoxifying properties and vitamin C content, is widely consumed by health enthusiasts and social media influencers.

But Dr Andrej Bozic, oral surgeon at Dentum, said the high acidity of lemon water poses a significant risk to dental health.

Dr Bozic said: “Lemon juice has a pH level of around 2, which is very acidic. This acidity can erode the enamel of your teeth, which is the hard, protective outer layer.”

Enamel erosion is irreversible and can lead to a number of dental problems, including tooth decay and increased sensitivity.

Dr Bozic said: “Once enamel is worn away, it does not grow back. Your teeth become more vulnerable to decay and damage.”

The enamel on the teeth acts as a shield against bacteria and harmful substances. When it erodes, the softer, more vulnerable layer underneath, known as dentin, is exposed. This can lead to:

Increased sensitivity “People often experience increased sensitivity to hot and cold foods and drinks when their enamel is eroded,” said Dr. Bozic.

Greater risk of cavities : “With less protection, your teeth are more susceptible to decay,” he added.

Aesthetic concerns : “Eroded enamel can also lead to tooth discoloration and a yellowish appearance,” Dr. Bozic warned.

How lemon water can cause damage

Many people enjoy starting their day with a glass of lemon water, believing it to be a healthy habit. However, drinking lemon water regularly can expose your teeth to prolonged acid exposure.

“Frequency and duration of exposure are key factors in enamel erosion,” said Dr. Bozic. “Sipping lemon water throughout the day or letting it sit in your mouth can amplify the damage.”

Tips to protect your teeth

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 contact between the acidic lemon water and your teeth, helping to prevent enamel erosion,” said Dr. Bozic. He also recommended rinsing your mouth with water afterward to neutralize the acid and remove any residual acidity.

He added: “Avoid brushing immediately after drinking lemon water; wait at least 30 minutes to allow the enamel to reharden”.

It also advises you to limit your intake to once a day to reduce acid exposure. “Consider less acidic alternatives, such as cucumber or mint-infused water, which are refreshing and gentler on the teeth,” he said.

Using fluoride toothpaste is another protective measure. “Fluoride helps strengthen enamel and provides additional protection against acid erosion,” said Dr. Bozic.
