A brighter, whiter smile is a confidence booster for many people. Teeth whitening treatments have become more accessible in recent years, and many people opt for them to improve their appearance. However, it’s important to know that certain foods can stain and damage newly whitened teeth. In this post, we’ll discuss the foods to avoid after teeth whitening and tips to maintain white teeth. 

Foods and Beverages to Avoid After Teeth Whitening

Dark or Strongly Coloured Liquids

One of the first things you must avoid after teeth whitening is dark or strongly coloured liquids such as coffee, tea, red wine, cola, and tomato juice. These beverages contain substances that can stain your teeth easily and reduce the effectiveness of the teeth whitening procedure. Instead, drink plenty of water, milk, or white wine to keep your teeth hydrated and avoid stains.

Acidic Foods

Another type of food that you must avoid after teeth whitening is acidic food. These include citrus fruits, tomatoes, vinegar, and pickles. Acidic foods can weaken your tooth enamel, making your teeth more vulnerable to tooth decay and yellowing. Instead, choose to eat white fish, white cheese, fruits with a low acid content, and foods that are not acidic.

Staining Foods

Certain foods, such as berries, beets, and soy sauce, can stain your newly whitened teeth and affect the brightness of your smile. It’s best to avoid these foods for at least 48 hours after your teeth whitening procedure. You can still enjoy white meats such as chicken and turkey, potatoes, and other vegetables that will not leave a stain.

Hard and Crunchy Foods

Hard foods such as nuts and chips can be abrasive and affect your teeth’ enamel. Crunchy foods can also cause chips and cracks on your newly whitened teeth. It’s best to avoid these foods for the first few days after teeth whitening and choose softer foods that are easy to chew and gentle on your teeth.

Hot and Cold Foods

Finally, you should avoid hot or cold foods after teeth whitening. Foods such as ice cream and hot soup can cause sensitivity and discomfort in your teeth. Instead, try lukewarm foods such as rice, pasta, and cooked vegetables that are easy to digest and will not cause discomfort.veneers procedure burwood

Foods and Beverages That Can Be Consumed After Teeth Whitening

White Meat and Fish

After teeth whitening, it’s important to stick to a ‘white diet’, which includes foods that are low in pigment. White meat and fish are great sources of protein that won’t stain your teeth. Try grilled chicken breast, fish tacos, or stir-fry with shrimp.


Cauliflower, sweet potatoes, and carrots: Eating vegetables is essential for your overall health and maintaining white teeth. Vegetables like cauliflower, sweet potatoes, and carrots are low in acid and won’t damage your newly whitened teeth.

Dairy Products

Milk, cheese, and plain yoghurt: Dairy products contain calcium and low acidity levels, which make them safe and healthy choices for your teeth after a whitening treatment. Low-fat cheese can also remove other food debris from your teeth and gums.

Water and Clear Fluids

Smoking and less water intake can also discolour your teeth. After you get your teeth whitened, it’s important to keep them hydrated with water and clear fluids such as coconut water, broth, and herbal teas. Steer clear of fizzy, carbonated drinks or fruit juices, as they are highly acidic and easily stain your teeth.

Tips for Maintaining White Teeth

Brush and Floss Regularly

We all know that good dental hygiene is key to maintaining healthy teeth and gums, but it’s also important for keeping your smile bright and white. Brush your teeth at least twice a day, ideally after meals, and floss at least once daily to remove plaque and food particles that can lead to staining. Consider using an electric toothbrush for an extra gentle and effective cleaning. 

Rinse with Water After Consuming Dark Foods and Drinks

Dark-coloured foods and drinks such as coffee, tea, red wine, and tomato sauce can stain your teeth over time. If you can’t resist your morning cup of coffee or red wine, try rinsing with water afterwards to help wash away the staining agents. This will help minimise their time to sit on your teeth and cause discolouration. 

Use a Straw When Drinking Dark Liquids

Using a straw is another way to minimise contact between staining liquids and your teeth. This is a particularly effective strategy when drinking beverages you know are likely to stain, such as coffee, tea, and red wine. 

Schedule Regular Dental Checkups

Visit your dentist twice a year for routine cleanings and checkups. This will not only keep your teeth healthy, but it will also allow your dentist to monitor any changes in the colour or condition of your teeth. They can also provide professional teeth whitening treatments if desired. 


Teeth whitening treatments are becoming more popular, but knowing how to maintain white teeth afterwards is important. Avoiding certain foods such as dark fruits, soy sauce, tomato sauce, soft drinks, and wine can prevent staining and damage to tooth enamel. Incorporating good oral hygiene habits and visiting your dentist regularly can help maintain a brighter smile. By following these tips, you can keep your teeth looking their best and feel confident in your smile. Contact our professional dental team at My Local Dentists to schedule your first consultation!
