Can Sprite stain your teeth with braces?

Sprite is a popular carbonated soft drink that contains high amounts of sugar and acid. Many teens and preteens drink Sprite on a regular basis. At the same time, many teens and preteens wear braces as part of their orthodontic treatment. This leads to an important question – can drinking Sprite stain your teeth if you have braces?

The short answer is yes, Sprite can potentially stain your teeth if you wear braces. The high sugar and acid content of Sprite can react with the brackets and wires of braces, leading to decalcification and enamel breakdown. This damage makes teeth more prone to staining and discoloration. However, the extent of staining depends on factors like how much Sprite you drink and your oral hygiene habits. With proper care, it is possible to enjoy Sprite in moderation without excessive staining.

How Braces Stain Teeth

Braces are effective at straightening teeth, but they also come with some downsides. The brackets, wires, and elastic bands used in braces provide places where plaque and bacteria can build up. Food debris and drinks like Sprite can become trapped around braces. Over time, this leads to decalcification under the brackets and where the bands wrap around each tooth. Decalcification is a loss of minerals from the enamel that makes teeth prone to staining.

In addition, the brackets and bands scratch against teeth while eating and drinking. This friction wears down the enamel, making teeth more porous. Porous enamel absorbs stain particles easily, leading to discoloration over time. Teeth with braces also stay wet longer after drinking Sprite, giving stain-causing compounds more time to soak into the enamel. All these factors make braces increase the likelihood of tooth staining.

Acids in Sprite Cause Enamel Erosion

One of the reasons Sprite can stain teeth with braces is due to its high acid content. Sprite contains both citric acid and phosphoric acid added as preservatives and flavoring agents. The citric acid gives Sprite its tart, tangy taste, while phosphoric acid provides a sharper flavor.

However, these acids also erode tooth enamel. Enamel is made of calcium phosphate crystals held together by a protein matrix. The acids in Sprite dissolve these minerals, especially around orthodontic brackets where acid can pool. This erosion makes the enamel weaker and more porous.

Over time, the acids can cause white spot lesions under and around braces. White spot lesions indicate areas where minerals have been lost. They appear as chalky white patches on teeth. These lesions allow stains to penetrate deep into the enamel where they become trapped. Even if the enamel remineralizes, these subsurface stains remain.

Sugar Causes Bacteria Overgrowth

Sprite has a very high sugar content, with approximately 40g of sugar in each 12oz can. The main sweetener used in Sprite is high fructose corn syrup. This processed sugar feeds oral bacteria that live in dental plaque.

When you consume sugary drinks, the bacteria metabolize and ferment that sugar into acids. These acids lead to demineralization and erosion of enamel. Braces make it harder to remove plaque through brushing and flossing. So the bacteria around brackets thrive on the sugar from Sprite.

In addition, some oral bacteria produce colored byproducts as they digest sugar. For example, chromogenic species like Actinomyces can cause yellowing. The more you feed these microbes with soda, the more they proliferate and release pigmented compounds that embed in enamel. This leads to deeper intrinsic stains over time.

Preventing Stains from Sprite with Braces

Brush after drinking and avoid swishing

One of the best ways to prevent stains from Sprite is to brush your teeth soon after drinking it. Swish plain water after finishing Sprite to help wash away sugar and acids. Then wait at least 30 minutes before brushing. This allows your saliva to naturally remineralize and harden the enamel. Brushing too soon can scrape away the softened enamel.

When you do brush, focus on all surfaces of each tooth, not just the front. Use a soft-bristled brush and fluoride toothpaste. Take extra time to gently clean around each bracket and under the wires. Try to dislodge any trapped food particles. Avoid swishing and spitting while brushing, as this spreads stains.

Use a straw to minimize contact

Drink Sprite through a straw to help minimize contact with your teeth. Aim the straw toward the back of your mouth. This reduces the time the sugar and acids touch your enamel. A straw also decreases the liquid friction against your braces that can wear down enamel.

However, do not use stainless steel straws. Metal can interfere with braces and even cause damage to the wires. Choose plastic, paper, or glass straws instead. Bendable straws can help you navigate around orthodontic appliances. Rinse with water after finishing your drink to wash away residue.

Limit Sprite intake

Restricting how much Sprite you consume can help control staining. The American Academy of Pediatric Dentistry recommends limiting sugary drinks to mealtimes only. They advise no more than one 8oz serving per day.

Try gradually reducing the amount of Sprite you have until you reach this recommendation. Substitute with healthier alternatives like water, milk, or unsweetened tea. If you do drink Sprite, go for the mini 7.5oz cans to control portions. Avoid frequent sipping throughout the day, which constantly bathes teeth in acid.

Get regular dental cleanings

See your dentist for thorough cleanings every 3 to 6 months. Professional scaling removes plaque buildup and external stains from around braces. The dentist can use tools to clean in areas that are hard to reach with normal brushing and flossing.

Cleanings help prevent gingivitis and periodontal disease. These gum infections make teeth more susceptible to staining. Your dentist may also apply fluoride treatments or prescription strength fluoride toothpaste to reinforce your enamel against acid damage. They can assess if you need to cut back on acidic drinks like Sprite.

Does Sprite Stain Worse than Other Sodas?

Sprite has a high potential to cause tooth staining, but other popular sodas can also contribute to discoloration. Staining depends most on the drink’s sugar content and acidity level. Here’s how Sprite compares:

Vs. Coke and Pepsi

Coke and Pepsi generally cause worse staining than Sprite. They have higher acidity at a pH of 2.5, compared to Sprite’s pH of 3.4. The darker caramel coloring in Coke and Pepsi also contributes to extrinsic surface stains on teeth.

However, Sprite has more sugar at 40g per 12oz can vs. 35g in Coke and 41g in Pepsi. The extra sugar translates to more plaque and bacteria production. All three sodas are highly acidic and sugary, so limiting consumption can prevent stains.

Vs. Mountain Dew

Mountain Dew is more likely to stain teeth than Sprite. It has a very high acidity with a pH of 3.2. Mountain Dew also contains yellow dye #5 (tartrazine) which can discolor enamel. Additionally, its sugar content is 46g per 12oz can. The combination of dye, acid, and sugar make Mountain Dew very staining.

Vs. Ginger Ale

Sprite causes more staining issues than ginger ale. Ginger ale has a pH around 3.2, similar to Sprite. However, ginger ale has approximately 25g of sugar per 12oz serving, compared to 40g in Sprite. The lower sugar content leads to less enamel erosion and bacteria production.

However, even unsweetened ginger ale is still acidic. So limiting intake of both drinks helps prevent discoloration with braces.

Tips for Removing Stains from Braces

If you develop stains on your braces from drinking Sprite, try these methods to remove or lighten them:

Baking soda and peroxide

Make a thick paste by mixing baking soda and hydrogen peroxide. Use a soft bristle toothbrush to gently scrub this paste on stains for 2-3 minutes. Baking soda is a mild abrasive that scrubs away surface stains, while peroxide bubbles away bacteria and bleaches discoloration. Rinse thoroughly when done.

DIY whitening gel

Mix equal parts hydrogen peroxide and baking soda into a smooth gel. Apply this directly onto stained brackets using a cotton swab or soft brush. Let sit for 5 minutes before rinsing. Repeat once per week to lift stains over time.

White strips

Apply white strips or custom whitening trays from your dentist for 30-60 minutes daily. The hydrogen peroxide gel lightens any enamel discoloration not covered by brackets. Avoid placing strips directly on top of brackets, as this can damage the glue.

Dental cleanings

Professional dental cleanings every 3-6 months remove tartar buildup and surface stains. Your dentist can use rubber cup polishers, ultrasonic devices, or air polishing to thoroughly clean brackets and teeth. This helps teeth appear whiter between visits.

Avoid staining foods/drinks

Limit foods like coffee, tea, wine, berries, and tomato sauce which can re-stain teeth. Avoid colored mouthwashes as well. Prioritize brushing and flossing after meals to remove food debris. Use a straw when drinking beverages other than water.


Sprite can lead to tooth staining around braces due to its high sugar and acid content. The sugar feeds plaque while the acids erode enamel and cause demineralization around brackets. This makes teeth more prone to both extrinsic and intrinsic discoloration over time.

However, you can take steps to minimize staining by brushing after drinking Sprite, using a straw, and restricting intake. See your dentist regularly for cleanings as well. With proper oral care, you can still enjoy an occasional Sprite without excessive staining issues. Moderation and diligence are key to maintaining your bright smile while undergoing orthodontic treatment.
