Do you have an important event this weekend? Maybe it’s your college graduation day or even your wedding, and you know there will be a ton of photos taken to remember the day by. Or maybe you’ve just finally had enough and decided that you don’t want to wait any longer to get the smile of your dreams.

If you’re wondering to yourself and asking, “How can I make my teeth white in a day?”, you’ll be happy to know that you have a few options.

Options for Whitening your Teeth (in a day)

Luckily, you have a fairly large selection of tooth whitening choices, even if you only have a day to achieve a brighter smile.

Below, we cover your best options if you’re trying to achieve a whiter smile within 24 hours. Keep in mind, results will vary on your individual situation:

Professional Whitening

If you prefer to have your teeth professionally whitened, you will need to book a one-day procedure, compared to having a custom whitening kit made.

If your dental office offers Zoom! tooth whitening procedures, you can have a whiter smile in just about an hour. In order to schedule this appointment with such short notice, you’ll have to be up to date on your check-ups and have a clean dental bill of health before your dentist will permit the procedure to take place.

If you need extensive dental work or have any signs of gum disease, your dentist is very unlikely to agree to whitening.

If you aren’t able to get in to your dentist last minute, there are some great at-home options that you can try – some of which have been reviewed here.

Baking Soda

You probably already have some of this in your cabinets right now. Baking soda has been used for centuries as a natural tooth whitener and you’ll be surprised with the results. If you’re not sure, check out the following video:

Baking soda works as a mild abrasive that is used to scrub stains from the surfaces of your teeth so if you have deep, internal stains, this might not be the best treatment for you.

To use, wipe your teeth with a dry towel, removing as much saliva as possible. Next, take your toothbrush, get it a little wet and dip it into a small container of baking soda. Brush your teeth as normal, paying special attention to any problem areas.

Brush for at least two minutes. Rinse and enjoy your brighter smile! The downsides of this treatment is that the taste isn’t great and it should only be done once a week at most to avoid damage to your tooth enamel.

Hydrogen Peroxide

Here’s another common household ingredient that you can use to whiten your teeth in a flash. It’s completely safe as long as used as directed but just be sure to avoid swallowing large amounts of it.

To use, dip a clean towel into the hydrogen peroxide and then gently rub your teeth with it. If you’re not a fan of using a towel, you can simply rinse with a small amount of hydrogen peroxide.


This is a surprising method to most people, even though its somewhat effective.

Strawberries contain folic acid, which has been shown to clean and even exfoliate your teeth, which helps to remove surface stains. Simply munching on a few after eating should help brighten your teeth. 

If you do any of these methods, be sure to avoid certain foods and drinks afterwards, like coffee, tea, grape juice and red wine or the stains will just come back.

Why Won’t My Teeth Get Whiter?

If you’re having trouble whitening your teeth, there are several factors that could be slowing down your treatment according to the American Dental Association.

  • Your Diet
  • Tobacco Use
  • Age
  • Trauma
  • Medication

If you’ve ever found yourself in a situation that led to you asking, “How can I make my teeth whiter in a day?”, you know just how desperate you were for an answer.
