The Effects of Sugary Drinks on Developing Teeth

Your child’s teeth are constantly working to repair and protect themselves — they simply need the right environment to do so.

By Dr Raveena Manga (Paediatric & Integrative Dentist)

As a paediatric dentist, I have the privilege of guiding parents toward small, sustainable, and thoughtful choices that can truly change the trajectory of a child’s oral health — by nourishing and supporting both the oral and gut microbiome.

Unfortunately, many foods, drinks, and snacks marketed as ā€œhealthyā€ contain hidden sugars, preservatives, colourants, flavourants, refined carbohydrates, emulsifiers, and stabilisers, to name a few. When consumed in excess, these can shift the microbiome into a state of dysbiosis, where harmful microbes begin to outweigh the beneficial ones.

This is particularly relevant when it comes to sugary drinks, including flavoured milks, fizzy drinks, sweetened iced teas, fruit juices, cordials, and sports or energy drinks.

As a mother myself, I understand the importance of allowing children to enjoy occasional ā€œtreatsā€, offering them in a mindful way so children can develop body awareness and learn moderation.

The goal isn’t perfection, it’s awareness, balance, and making informed choices that support your child’s wellbeing.

Understanding the Balance: How Teeth Protect Themselves

Your child’s teeth are constantly renewing themselves through a natural process of demineralisation and remineralisation.

• Demineralisation occurs when sugars are consumed. Harmful oral bacteria feed on these sugars and produce acids, which lower the pH and begin to draw essential minerals (calcium and phosphate) out of the enamel.

• Remineralisation is the body’s repair system. Saliva helps neutralise acids and replenish those lost minerals, strengthening the enamel again.

In a healthy environment, these two processes remain in harmony, allowing enamel to stay strong and resilient.

Early childhood decay is one of the most common childhood diseases globally. If early enamel changes are not identified and supported through remineralisation, this can progress into a cascade of decay — often requiring repeated treatment, loss of healthy tooth structure, and sometimes even loss of the tooth.

Prevention is key.

How Sugary Drinks Disrupt This Balance

Sugary drinks can easily tip this delicate balance. They provide a continuous fuel source for acid-producing bacteria. Many are acidic themselves, contributing directly to enamel wear. Frequent sipping keeps the mouth in a prolonged acidic state.

When teeth don’t have time to recover, the balance shifts toward demineralisation and when this consistently outweighs remineralisation, dental decay develops over time.

Simple, Supportive Swaps

The reality is that most children will be exposed to refined sugars at some point, including sugary drinks. Rather than taking an all-or-nothing approach, we encourage families to focus on gentle, sustainable changes.

Here are some practical starting points:

• Offer water as the primary drink with and between meals

• If your child prefers sweeter drinks, try making water more appealing by infusing

it with mint, berries, citrus, or cucumber

• Offer sugary drinks at structured mealtimes, rather than frequent sipping

throughout the day

• Keep sugary drinks as occasional treats

• Help your child understand the difference between ā€œfun foodsā€ and foods that

ā€œgrow, nourish, and buildā€ their bodies

A Thoughtful Alternative

For families looking to reduce sugar without removing enjoyment, sugar-free options can be a helpful bridge.

The Carmien Cold Brew Rooibos Teas for Kids are a wonderful option, made with clean ingredients, naturally flavourful, and gentle on the oral microbiome. They can make healthier choices feel easy, enjoyable, and sustainable for the whole family.

Food for Thought

Your child’s teeth are constantly working to repair and protect themselves — they simply need the right environment to do so.

With mindful, everyday choices, you can support not only your child’s smile, but also their comfort, confidence, and long-term health.

It’s not about being perfect, it’s about being consistent.
