What to Drink With Braces: What's Safe and What to Avoid
The Drinks Question Nobody Thinks to Ask
When patients get their braces fitted at Dr Gray Dentistry in Durban, the conversation about food restrictions is expected. Everyone anticipates being told to avoid hard and sticky foods. What catches many patients off guard is discovering that drinks matter just as much as food during orthodontic treatment — and that some of the most commonly consumed beverages can cause significant damage to the teeth during the months or years that braces are worn.
The concern is not about brackets and wires. Drinks do not break brackets. The concern is about what certain drinks do to the tooth surfaces that are partially covered and held against liquid for extended periods by the orthodontic appliance — and the answer, for some drinks, is genuinely worrying.
Dr Gray covers drink guidance as part of the comprehensive patient education provided at the start of every orthodontic treatment at Dr Gray Dentistry — because patients who understand why certain drinks are problematic make better choices consistently, rather than following rules they don't fully understand.
Why Drinks Are a Bigger Concern With Braces Than Without
To understand why drinks matter more during orthodontic treatment, it helps to understand what happens when a sugary or acidic drink enters a mouth that has braces.
Without braces, saliva plays a crucial role in neutralising acids and sugars after they are introduced into the mouth. Saliva flow washes around the teeth, dilutes the harmful components of drinks, and helps restore the normal pH of the oral environment relatively quickly after consumption.
With braces, the brackets and wires create additional surfaces, recesses, and areas where liquid pools and lingers around the tooth surfaces. Sugary or acidic drinks that sit in these spaces for extended periods — as they do around brackets and under wires — have prolonged contact with the enamel in exactly the areas where white spot lesions are most likely to form. The protective buffering action of saliva is less effective in these spaces than on open tooth surfaces.
The result is that a drink that would cause minimal damage to teeth without braces can cause significant enamel damage to teeth with braces if consumed regularly — because the appliance creates the conditions for prolonged acid and sugar contact with vulnerable enamel surfaces.
What to Drink Freely
Water
Water is the only drink that can be consumed freely at any time during orthodontic treatment — with or without the aligners in for clear aligner patients, and without any concern at any stage of brace treatment. Plain water does not contain sugar or acid, does not contribute to enamel demineralisation, and actually helps rinse food debris from around the brackets between brushing.
Still water is preferable to sparkling water during orthodontic treatment. Sparkling water — including unflavoured sparkling water — is mildly acidic due to the dissolved carbon dioxide that creates the bubbles. While it is significantly less acidic than soft drinks and fruit juices, regular consumption of sparkling water throughout the day does contribute a mild acid exposure that still water does not.
Milk
Plain milk is one of the most braces-friendly drinks available. It contains no added sugar in its natural form, has a near-neutral pH, and provides calcium and vitamin D that directly support bone health and the remodelling process that underlies tooth movement. Including milk as a regular drink during orthodontic treatment is actively beneficial rather than merely harmless.
Plain herbal teas without sugar
Herbal teas that do not contain tannins — such as chamomile, peppermint, rooibos, and ginger tea — consumed without sugar are gentle on the teeth and braces. They do not contribute to staining in the way that black tea and coffee do, and they do not contain sugar or significant acidity. Rooibos in particular is a South African staple that is naturally caffeine-free, naturally slightly sweet, and entirely safe for braces patients.
Drinks to Consume With Caution
Tea and coffee
Plain black tea and coffee without sugar are not directly damaging to the enamel — they are low in sugar and their acidity is relatively mild compared to soft drinks and fruit juices. The concern with tea and coffee during orthodontic treatment is primarily aesthetic: both drinks stain, and with brackets on the teeth, staining can occur unevenly. The tooth surface under the bracket is protected from staining while the exposed surfaces around it stain, and when the brackets are removed the difference in colour can be noticeable.
If tea or coffee is consumed during treatment, doing so without sugar, rinsing with water afterward, and maintaining excellent brushing habits reduces both the staining and any mild acid exposure. Adding milk reduces the staining potential somewhat by diluting the pigments.
Flavoured water and vitamin waters
Many patients assume that flavoured water is as safe as plain water — but this is frequently not the case. Many commercially available flavoured waters contain added sugar, citric acid, or both. The flavouring that makes them taste pleasant is typically achieved through acidic and sweet additives that make them significantly more damaging than plain water. Always check the ingredient list of any flavoured water before assuming it is safe for regular consumption during orthodontic treatment.
Smoothies and fruit juices consumed in one sitting
Freshly made smoothies and fruit juices contain natural sugars and natural acids from the fruit. Consumed occasionally and in one sitting — rather than sipped slowly over an extended period — the damage potential is manageable. The problem arises when smoothies or juices are sipped slowly over 30 minutes or more, because this prolongs the acid and sugar exposure significantly. Drink smoothies and juices quickly rather than nursing them over time.
Drinks to Avoid or Minimise Significantly
Soft drinks and carbonated beverages
Soft drinks are one of the most damaging drink choices for orthodontic patients — and the damage comes from two simultaneous mechanisms: high sugar content and high acidity.
The sugar in soft drinks feeds the bacteria in dental plaque, which produce acid as a byproduct. The drink itself is also highly acidic — pH values for most carbonated soft drinks are between 2.5 and 3.5, which is significantly more acidic than saliva's normal pH of around 7. The combination of direct acid exposure and bacterial acid production from sugar creates a highly damaging environment for enamel, particularly in the recesses around brackets where the liquid lingers.
Diet soft drinks are marginally better in terms of sugar content but are equally acidic. The acidity of a diet cola is similar to that of its full-sugar counterpart, meaning the enamel erosion risk remains even without the sugar-driven bacterial acid production.
If soft drinks are consumed during orthodontic treatment, Dr Gray recommends:
Drinking through a straw to reduce direct tooth contact. Consuming the drink in one sitting rather than sipping over time. Rinsing with water immediately afterward. Waiting at least 30 minutes before brushing — brushing immediately after acid exposure can actually increase enamel damage by abrading softened enamel.
But the most straightforward recommendation is to significantly reduce or eliminate soft drink consumption for the duration of orthodontic treatment.
Sports drinks and energy drinks
Sports drinks and energy drinks are among the most damaging beverages available for tooth enamel — frequently more so than soft drinks. They combine high sugar content with very high acidity, are often consumed over extended periods during physical activity, and their marketing as healthy or performance-enhancing products masks their significant dental risks.
Popular sports drinks have pH values between 2.4 and 4.5 — placing them in the same range as soft drinks in terms of acidity. Consumed during sport, when the mouth is often dry from exertion and saliva flow is reduced, the acid exposure is even more damaging than it would be in normal conditions.
For patients playing sport during orthodontic treatment, water remains the ideal hydration choice. If a sports drink is felt to be necessary during intense or prolonged exercise, drinking it quickly rather than sipping throughout, and rinsing with water afterward, reduces the damage potential.
Fruit juices consumed regularly throughout the day
Fruit juice — even freshly squeezed, 100% natural juice — is significantly acidic. Orange juice, grapefruit juice, apple juice, and most other fruit juices have pH values between 3.0 and 4.0, placing them in a similar damage range to soft drinks in terms of acid exposure. They also contain significant natural sugar.
Fruit juice consumed occasionally and in one sitting is not a major concern. Fruit juice sipped regularly throughout the day — kept in a bottle and consumed over hours, creates a sustained acid environment around the teeth and brackets that is genuinely damaging over the course of orthodontic treatment.
The Sipping Problem
One specific behaviour that dramatically increases the damage potential of any drink beyond water is slow, extended sipping throughout the day.
When a drink is consumed in one sitting, the acid and sugar exposure is concentrated into a single episode. Saliva then has the opportunity to neutralise the acid and restore normal pH over the following 20 to 30 minutes. The enamel experiences one acid challenge and then recovers.
When the same drink is sipped slowly over an hour, as many people do with coffee, juice, soft drinks, or flavoured water at their desk, the acid and sugar exposure is sustained continuously for the entire sipping period. The enamel never has the opportunity to recover between acid exposures. The cumulative damage from one hour of sipping is significantly greater than the damage from one sitting consumed in five minutes.
During orthodontic treatment, where the brackets and wires create additional pooling of liquid around the teeth, the damage from extended sipping is magnified further. Dr Gray advises patients at Dr Gray Dentistry to drink anything other than water in one sitting where possible, and to follow any non-water drink with a water rinse.
Practical Tips for Staying Hydrated With Braces
Applying these principles practically throughout a busy day:
Keep a large water bottle as the default drink throughout the day. Save tea, coffee, or other drinks for specific moments rather than sipping throughout the day. When consuming acidic or sugary drinks, use a straw where possible to reduce direct tooth contact. Always follow any non-water drink with a rinse of plain water. Avoid brushing for at least 30 minutes after consuming an acidic drink. At restaurant meals, choose water or milk as the accompanying drink rather than soft drinks or juice. Be aware of the sugar and acid content of drinks that are marketed as healthy, sports drinks, vitamin waters, and fruit juices are frequently more damaging than their branding suggests.
