After teeth whitening performed under dental supervision at our clinic, your teeth may be temporarily more prone to external staining during the first few days. For this reason, following a "white diet"—especially during the first week—helps preserve the brightness you have achieved. How long the result lasts can vary depending on your diet, smoking, oral hygiene and individual factors.
What to Expect After Whitening
First 72 Hours (Most Critical Period)
This is when the risk of staining is highest. During this time, try to consume only light-coloured ("white diet") foods and drinks as much as possible.
- Avoid coffee, tea, Turkish coffee and espresso.
- Avoid cola, energy drinks and coloured soft drinks.
- Avoid red wine and fruit juice.
- Stay away from strongly coloured foods such as tomato sauce, tomato paste, curry, turmeric, soy sauce and pomegranate molasses.
- Avoid chocolate and dark-coloured fruits (pomegranate, sour cherry, cherry, blackberry, blueberry, etc.).
- Do not use cigarettes or other tobacco products.
- Drink plenty of water.
First 7 Days
After the first 72 hours the risk of staining decreases but does not disappear completely. For the best and longest-lasting result, it is recommended to keep to the white diet as much as possible throughout the first week.
- White cheese, plain yoghurt, milk and ayran are good choices.
- Chicken, turkey, fish, rice, pasta (without sauce), boiled potatoes and eggs can be eaten.
- If you must have a coloured food or drink, rinse your mouth and drink plenty of water afterwards.
- Avoid very hot or very cold foods and drinks.
- Avoid smoking as much as possible.
1-2 Weeks
You can gradually return to your normal diet. However, frequently consumed staining foods can shorten how long the whitening lasts.
- Limit coffee and tea as much as possible.
- Drink water or rinse your mouth after coloured drinks.
- Continue regular brushing and flossing.
- Before starting whitening toothpastes, it is recommended to wait as long as your dentist advises (usually around 2 weeks).
- If sensitivity persists, contact our clinic.
Long-Term Care
How long whitening lasts varies from person to person. Regular oral care and good habits help maintain the result for longer.
- Have a dental check-up and professional scaling every 6 months.
- Floss regularly and clean between your teeth.
- Reducing or quitting smoking will lower the risk of staining.
- When needed, touch-up applications can be planned on your dentist's recommendation.
Managing Sensitivity
Temporary sensitivity may occur during the first few days after whitening. In most patients this settles on its own.
-
Use a desensitizing toothpaste.
Desensitizing toothpastes containing potassium nitrate or stannous fluoride can provide relief. Unless your dentist recommends a different product, you can use one regularly for the first few weeks.
-
Avoid very hot and very cold foods.
Choosing lukewarm foods and drinks during the first days will be more comfortable.
-
Use a soft-bristled toothbrush.
Brush your teeth gently and do not skip your oral care routine.
-
Contact us for severe or long-lasting sensitivity.
Sensitivity is expected to ease within a few days. If severe pain develops or your complaints continue for a long time, please contact our clinic.
Why We Recommend a White Diet
-
Teeth can be more prone to staining in the first days.
After whitening, the tooth surface may be temporarily more susceptible to external staining. For this reason, staying away from staining foods and drinks as much as possible during the first week is recommended.
-
The care you take in the first week can affect the result.
Frequent early consumption of coffee, tea, cigarettes and strongly coloured foods can cause the brightness you achieved to fade sooner.
-
Drinking water helps.
Drinking water or rinsing your mouth with water after coloured foods and drinks can help reduce the risk of staining.
-
Regular oral care helps preserve the brightness.
Regular brushing, flossing and professional cleaning help maintain the whitening result for longer.
