After a teeth-whitening session, the pores of the teeth will be slightly opened, putting them at risk of discoloration. It takes about 72 hours after a whitening for your teeth to be able to consume the food / products you would normally eat / drink.

Fortunately, The Smile Bar Hong Kong offers a perfect solution: The Nano Seal Total+. By using it at the end of your whitening, you will be able to keep your usual lifestyle, without any restriction, otherwise please follow the below advises about what’s good to drink and eat after a whitening.



You will find below the list of the most recommended drinks that do not affect or even improve the effects of the teeth whitening.

Soft Drinks

Still & Sparkling Water
Soda Water
Tonic Water
Skim Milk

The best beverage is Water. Mineral water is by far the most recommended drink and can be either still or sparkling but not flavored. It is recommended to drink plenty of it.

Skimmed milk is also a safe drink however it is recommended to avoid full fat milk (cf. WHAT’S NOT GOOD)

Alcoholic Drinks

If you like a glass of wine with your dinner white wine is definitely better than red wine but still not recommended (cf. WHAT’S NOT GOOD).

If you are in a celebration mood it is advised to choose wisely your alcohol.
White spirits like Vodka, Gin, White Rum, White Tequila and White Wine (to a certain extent) are the only alcoholic drinks that will not discolor your teeth. If you are drinking White spirits it is important to mix it with ice only or tonic/soda water.


White Meat & White Sauces
Chicken, Turkey or White Fishes (Cod, Haddock, Halibut and Plaice)

It is recommended to steam, poach, boil or grill (without oil or spices or any coloring condiments)

White sauces are also recommended except the one with a cheese base.

White Fruits & Vegetables
Banana, Apple, Pineapple
White Beans, Cauliflower, Parsnip

Garlic, Ginger, Onion, Turnip and Potatoes (without their skin)

Bread and Cereals
White, light and thin bread such as pita bread
Rice Crispies are also good but remember to use skimmed milk
Steam plain rice with no seasoning will constitute a good accompaniment for your meals

Chewing gum that is white and not too strong

Below you will find more details regarding the common food/products.

Cheese – Rich in protein, calcium and phosphorus, all of which can help safeguard against the acids in your mouth.

Salmon – provides calcium and vitamin D, nutrients needed for healthy bones and teeth.

Raw Vegetables
Foods that are high in fiber and slightly coarse act as a scrubbing agent for teeth. Much like a kitchen-scouring pad gets pots clean, the florets of vegetables like broccoli and cauliflower can help do the same to teeth.
Added benefits: The high iron content in dark greens like broccoli also helps form a thin coat that protects teeth from enamel-eroding acids found in soda and carbonated drinks. And good news for celery lovers: Because it’s so difficult to chew, it increases saliva production and polishes teeth for a natural surface clean.

Shiitake mushrooms contain a tooth-friendly compound called lentinan, which inhibits the growth of damaging bacteria that cause tooth decay and discoloration. If you’re not fond of fungi, try mixing them into a stir-fry for more masked consumption (but remember to skip the soy sauce).

They may not do great things for your breath, but onions contain antibacterial sulfur compounds that prevent plaque from forming on your teeth. And their lingering flavor helps whiten teeth in an indirect way: You’re more likely to brush your teeth after eating them.
Unfortunately, onions must be consumed raw to reap the anti-plaque benefit, so include them on sandwiches and in salads whenever you can.

Ginger – acts as an anti-inflammatory to support healthy mouth tissue.

Carrots – contain vitamin A, which is needed for healthy tooth enamel, however this good looking root will have to wait at least 72 hours after the whitening. Basil – is a natural antibiotic that reduces bacteria in the mouth.

Similar to cucumber you can take advantage of peeling away the outer skins of some fruits to give you more variety. Bananas are a safe option as they’re obviously white. However, the inside of apples and pears are ideal too, so they are safe to consume provided you peel the skin off and eat only the white part. Apples, pears and guavas also keep teeth debris and gum bacteria at bay. Their crisp texture and high water content increases saliva, washing away harmful bacteria that creates plaque and leads to discoloration over time.

Citrus Fruits
The acids found in citrus fruits are effective teeth whiteners. Additionally, their tart taste enhances saliva production for a natural rinse and polish.
Pineapples specifically contain an enzyme called bromelain that can assist in removing stains.

Strawberries contain malic acid, which acts as a natural astringent to help break down and remove surface stains. Eating them will do the trick, but if you want an even better dose of the berry, it is suggested to crush a few up, combining with baking soda and brushing with the mixture.


Like apples, munching on nuts such as almonds, cashews, walnuts, and sesame seeds stimulates saliva, which can help wash away bacteria.
What’s more, nuts’ abrasive texture can also work at removing existing surface stains.
