After investing in a teeth whitening treatment, it’s important to develop habits that help you keep your bright smile for longer. One of the key steps is to pay attention to what you eat and drink. For at least 48 hours after your treatment, follow a “white diet” — that means avoiding foods and drinks that can stain your teeth. During this time, your enamel is more porous and can easily absorb colours. Sticking to light-coloured, non-acidic foods helps protect your teeth and maintain your whitening results for weeks to come.
Dark-Coloured Beverages
If you’ve just had the best teeth whitening in Aberdeen, caring for your smile starts right after treatment. Drinks like coffee, tea, cola, and coloured sports drinks are among the main causes of tooth discolouration. They contain tannins and acids that can easily seep into enamel and create stains. To keep your teeth looking bright, avoid these drinks for at least two days after your whitening session. If you really need your morning coffee, use a straw and rinse with water immediately. These simple habits help preserve your radiant smile for longer.
Red and White Wine
Red wine is known for staining teeth due to its dark pigments and acidity. However, white wine can also cause problems. Even though it doesn’t leave visible stains, its acids can weaken your enamel, making it easier for other foods and drinks to discolour your teeth later. For best results, avoid drinking any wine for at least 48 hours after your treatment. If you’re at an event, choose water or sparkling water instead. This not only protects your enamel but also keeps your mouth hydrated and fresh.
Dark-Coloured Fruits and Vegetables
Fruits like blueberries, blackberries, and pomegranates are healthy but not friendly to freshly whitened teeth. The same goes for vegetables like beetroot, which have strong natural pigments that cling to enamel. When your teeth are newly whitened, they can easily absorb these dark colours, leading to stains. It’s best to wait a few days before reintroducing such foods. Choose lighter fruits such as peeled apples or pears instead. This will allow your enamel to recover while still giving you the vitamins and fibre your body needs.
Tomato-Based and Dark Sauces
Rich, dark sauces such as tomato, soy, balsamic vinegar, or barbecue sauce may taste delicious, but they can damage your new white smile. These sauces are full of pigments and acids that stick to your teeth and soften enamel. To avoid stains, try lighter sauces like white or cream-based ones. You can also add herbs and mild seasoning for flavour. Waiting a few days before eating tomato or dark sauces gives your teeth time to strengthen and keeps your bright results for longer.
Acidic Foods and Drinks
Citrus fruits like oranges, lemons, and limes are refreshing but highly acidic. The same applies to vinegar-based dressings, tomatoes, and pickles. After whitening, your teeth may feel more sensitive and porous, allowing acids to wear away the enamel faster. This can lead to pain and dullness. To stay safe, avoid acidic foods and drinks for a few days. Choose mild options like bananas, cooked vegetables, and white meats. This will help your enamel recover fully while keeping your smile healthy and comfortable.
Sugary Treats and Fizzy Drinks
It’s best to stay away from sweets, chocolate, cakes, and fizzy drinks right after teeth whitening. These foods encourage bacterial growth and plaque, which can lead to stains and tooth decay. The sugar and carbonation also make your enamel weaker. If you crave something sweet, go for plain yoghurt or a banana instead. Always rinse your mouth or brush your teeth gently after eating. By limiting sugar and soft drinks, you’ll not only keep your teeth white but also improve your overall dental health.
Foods with Artificial Dyes
Many packaged foods contain artificial colours that can quickly stain teeth, especially after whitening. Items such as colourful sweets, cereals, sauces, or processed snacks often have strong dyes that stick to enamel. These colours are designed to last, making them hard to remove once they attach. Read product labels and avoid anything with bright red, blue, or purple colouring. Choose natural, plain options for at least two days after treatment. Your teeth will stay whiter, and you’ll avoid exposing your mouth to unnecessary chemicals.
Sticky and Processed Foods
Sticky foods like dried fruits, caramel, and toffees cling to the surface of your teeth and can trap coloured pigments. Processed meats, including sausages and salami, often contain dyes and preservatives that cause discolouration over time. These foods also increase the risk of plaque build-up. Try to eat soft, white, and easy-to-clean foods such as mashed potatoes or eggs instead. This helps protect your whitening results while allowing your enamel to settle. It’s a small sacrifice that gives lasting benefits to your smile.
Alcohol and Tobacco
Both alcohol and tobacco can quickly ruin your whitening results. Dark alcoholic drinks, such as rum or whisky, contain pigments that stain enamel, while the acids weaken it. Smoking or chewing tobacco causes heavy yellowing that can return even after a single use. For the best outcome, avoid both entirely, especially during the first 48 hours. Instead, drink plenty of water and chew sugar-free gum to freshen your breath. Your smile will stay cleaner, brighter, and much healthier in the long term.
What You Can Safely Eat
Thankfully, there are still many foods you can enjoy after whitening. A “white diet” includes light-coloured, non-acidic foods that don’t stain. Focus on foods such as chicken, white fish, rice, bread, and dairy products. Potatoes, parsnips, and cauliflower are excellent vegetable options. These choices are easy on your enamel and keep your smile glowing. Bananas and peeled apples are safe fruit options. And above all, drink plenty of plain water throughout the day — it washes away food particles and protects your teeth naturally.
Long-Term Whitening Tips
To keep your smile bright for months, build good daily habits. Use a straw when drinking coffee, tea, or other dark drinks. Brush your teeth twice a day with a whitening-friendly toothpaste. Schedule touch-up whitening every few months if needed. Limit alcohol, coffee, and wine, and avoid smoking altogether. Regular dental check-ups and professional cleanings are essential for long-term care. With proper habits, you can enjoy your confident, radiant smile long after your initial whitening treatment.

Frequently Asked Question
Can I drink tea or coffee after teeth whitening?
It’s best to avoid tea and coffee for at least 48 hours after whitening, as both can stain your teeth. If you decide to drink them later, use a straw to reduce contact with enamel and rinse your mouth with water immediately after. This simple step helps you maintain your whitening results for longer.
Can I eat chocolate after teeth whitening?
Chocolate, especially dark types, should be avoided in the first few days after whitening. Its strong pigments and sugar can cause stains and enamel sensitivity. Milk chocolate may be slightly safer once your enamel settles, but moderation is key for keeping your teeth bright and healthy.
Can I consume citrus fruits after teeth whitening?
No, it’s best to stay away from citrus fruits like oranges, lemons, and limes for a few days. Their acidity can weaken enamel and cause sensitivity right after whitening. Once your teeth recover, you can reintroduce them slowly to your diet.
Is it safe to drink red wine after teeth whitening?
Red wine contains tannins and dark pigments that can quickly stain teeth. It’s best to avoid it for at least 48 hours, or longer if possible. Instead, opt for water or white-coloured drinks to protect your smile and keep your enamel strong.
Can I eat spicy foods after teeth whitening?
Spicy foods can irritate your gums and sensitive enamel following whitening treatment. To stay comfortable, avoid them for two to three days. Once sensitivity decreases, you can gradually add mild spices back into your meals.
