When it comes to making your smile look better and brighter, few services can have a bigger impact than teeth whitening. This non-invasive dental procedure uses special products to remove the intrinsic and extrinsic stains that discolour your teeth, helping restore a white, clean look. To continue enjoying these benefits there are some foods to avoid after a teeth whitening. After all, teeth whitening will last only as long as you continue to take care of your teeth.

The wrong foods can disrupt the longevity of your treatment. So which foods should you absolutely avoid if you wish to maintain a bright, white smile during your teeth whitening procedure? The following items should be at the top of your “do not eat/drink” list.

1. Coffee & Tea

Coffee and tea are some of the biggest culprits behind stained teeth in the first place, which makes them a definite item to avoid after your teeth whitening treatment. Your tooth enamel contains countless tiny pores where food and drink particles can get trapped — and coffee and tea are easily trapped in these microscopic pores and ridges. Worse yet, the dark colouration can create permanent yellow stains. Avoid drinking coffee or tea after your teeth whitening service, and for lasting results, try to limit your consumption as much as possible. If you don’t think you can go without coffee, drink it quickly and through a straw, having the least amount of liquid contact your teeth and rinsing with water after drinking it may help.  

2. Red Wine

Red wine is another dark, staining liquid to avoid after getting your teeth whitened. Red wine is highly acidic, which wears away at the enamel of your teeth. Another problem with red wine is that it contains tannins, which are an astringent compound that binds to the teeth and make it easier for stains to set in. As with coffee and tea, red wine should be avoided during and in the initial days following your teeth whitening service.

3. Berries & Juice

Most fruits (especially berries) are very acidic, resulting in wear and tear on your tooth enamel. This won’t just affect the longevity of your teeth whitening — it can also cause some pain during eating, as your mouth is typically more sensitive after this service. Stay away from juices as well!

4. Dark Sauces

Soy sauce, tomato sauce, ketchup and other dark sauces are all a definite no-no. Essentially, if it is something that would stain your shirt, you should keep it off your plate for a few days. Vinegar-based condiments (especially balsamic vinegar) should especially be avoided due to their high acidity. It may be tough to go without the flavours of your favorite condiment or marinade, but the longer you can avoid them, the longer your teeth will stay white and bright.

If having a bright white smile is something you desire, making minor adjustments to your diet during the whitening procedure is a small price to pay to have a beautiful smile in the end! Who knows, maybe you’ll even end up kicking your coffee addiction to the curb and put a stop to yellow teeth once and for all!
