Last Updated: December 10, 2024 Approved

Everybody wants pearly, white teeth for a dazzling smile. And while good oral hygiene and regular visits to your dentist will help to keep your teeth looking good, sometimes you need a more immediate solution -- especially if you want whiter teeth for a particular event or occasion. Luckily, there are several things you do to get whiter teeth in under an hour (and even in just three minutes)!

1
Use baking soda. Baking soda can be used to effectively whiten teeth in the space of a few minutes! This is due to the fact that baking soda is a mild abrasive which helps to scrub stains from your teeth. ^{[1]

- To use, wipe your teeth with a dry towel and any remaining saliva. wet your toothbrush and dip it in some baking soda. Then brush your teeth as normal, paying special attention to the 16 visible teeth at the front. You should brush for about three minutes.
- Be aware that, over time, baking soda can wear down the protective enamel on your teeth. Therefore, it is not a good idea to use this treatment everyday. Stick to using it once or twice a week for whitening results without the risk of damage.
2
Use hydrogen peroxide. Hydrogen peroxide can be used to bleach your teeth, making them whiter. It is completely safe to use, provided you avoid swallowing it. ^{[2]

- One way to use the hydrogen peroxide is to dip a clean face cloth in the liquid, then use the soaked cloth to gently rub your teeth. The hydrogen peroxide will remove stains chemically, while the cloth will help to remove them physically.
- Alternatively, you can rinse out your mouth with a cap full of hydrogen peroxide (which also helps to kill bacteria and freshen breath) or dip your toothbrush in the hydrogen peroxide and use it to brush your teeth.

Eat strawberries. After a meal, you should munch on a couple of strawberries for dessert. Strawberries contain folic acid, which actually helps to clean and exfoliate teeth, making them appear whiter. ^{[3]

- You can also mash a strawberry and mix it with some baking soda for a natural whitening toothpaste.
- Other foods that help to naturally clean and whiten teeth include apples, pears, carrots and celery. ^{[4]

Avoid eating or drinking items that could stain your teeth. If you need to keep teeth looking white, it's a good idea to avoid certain foods and drinks that can stain your teeth, such as coffee, black tea, red wine, grape juice and curry. ^{[5]

- If you do drink any of the above-mentioned beverages, you can prevent them from staining your teeth by drinking them through a straw, or by rubbing a light layer of Vaseline over your teeth beforehand.
- Alternatively, you can chew a stick of sugar-free whitening gum after eating or drinking these items. This can help to absorb any newly-formed stains, making your teeth look whiter. ^{[6]

1
Use whitening toothpaste. Although whitening toothpastes will not dramatically improve the whiteness of your teeth in the space of an hour (they are more effective over time), they can still help to remove stains and make teeth look brighter.
- Whitening toothpastes contain abrasive particles which polish the teeth and wear away stains (without damaging tooth enamel). They also contain chemicals (such as blue covarine) which bind to the surface of the teeth, making them appear whiter. ^{[7]

- To use whitening toothpaste, place a pea-sized amount on your toothbrush, and brush using small circular motions, holding the toothpaste at a 45-degree angle from the gums.
2
Use whitening strips . Whitening strips are coated with peroxide gel, which bleaches the teeth and helps them to look whiter. ^{[8]

Expert Interview. 10 April 2020.} You will typically use two sets of strips per day, for 30 minutes each -- giving you a whiter smile in only 60 minutes!
- Whitening strips can be purchased over-the-counter at the drugstore or supermarket. Avoid purchasing a brand that contains the ingredient "chlorine dioxide" as this can damage the enamel on teeth.
- To use the strips, remove them from the package and apply one strip to your top teeth and one to your bottom teeth. Leave them on for 30 minutes. Some strips will dissolve by themselves after use, while others will need to be removed.
- For best results, continue to use the whitening strips twice a day over a two week period.
3
Use a whitening pen. Like the whitening strips, whitening pens use a gel containing peroxide in order to bleach the teeth.
- To use, remove the cap and twist the pen to release the gel. Stand in front of a mirror and smile widely, then use the pen to "paint" the gel onto your teeth.
- Keep your mouth open for about 30 seconds to allow the gel to dry. Try not to eat or drink anything for 45 minutes following the treatment.
- For best results, repeat this process three times a day for up to a month.
4
Use a whitening tray. A whitening tray is another great option for quickly whitening your teeth. They can be purchased over-the-counter or can be custom-made by your dentist.
- To use a whitening tray, squirt a small amount of the concentrated peroxide gel provided into the tray (which looks like a plastic retainer) and fit it over your teeth.
- Depending on the type of tray, you may only need to wear it for half an hour, or you may have to leave it on overnight. Although a single use will leave your teeth looking brighter, if you want significantly whiter teeth you will need to use the tray multiple times.
- Although custom-made trays from your dentist can be pricey (usually costing around $300), they are specially molded for your teeth, making the treatment more effective than store-bought "one size fits all" trays.

- This will help to keep your teeth in tip-top condition, preventing tooth decay and gum disease in addition to making your teeth nice and white.
- Your dentist can also perform an in-office bleaching treatment which is like the whitening trays you use at home, except the bleaching solution is much stronger.
2
Get laser treatment. Another very effective option is to get a laser whitening treatment. These can be expensive, but are quick and will produce very effective results.
- A bleaching gel is applied to your teeth, then a rubber shield is placed over your gums. A laser or white light is then directed towards your teeth, activating the bleaching gel.
- Depending on how white you want your teeth, you may need to return for several sessions. However, each session only lasts about 30 minutes. ^{[10]

Expert Answer

Whitening your teeth that fast is always a bad decision. The fastest way takes about half an hour in the dentist chair, using a high percentage of hydrogen peroxide activated by the lamp or laser. You can also ask your dentist for a fast air polishing procedure which removes stains and takes only about seven to 10 minutes.

If you have braces, use an interproximal toothbrush to get into the nooks and crannies. Don't use pipe cleaners, no matter how similar, as the fuzz can get stuck on your braces and can get stuck enough that you need to go to the dentist or orthodontist to remove it. ^{[11]

I had bad gingivitis and this is what I do: mix a half teaspoon of peroxide and a half teaspoon of baking soda with some regular whitening toothpaste. Then, brush with the paste for 3 minutes. My teeth were white in one week.
If you're a smoker, quit smoking (cigarettes stain your teeth). Ask your doctor about nicotine patches or gum. There are also certain medications like Chantix or Wellbutrin that can aid in helping you quit.
Getting a tan or wearing a darker lip color can also give the appearance of brighter, whiter teeth.
