1. 1

   Brush and floss. Brushing and flossing immediately lifts stains that have recently been left on your teeth.^[1] Use a whitening toothpaste and brush well, focusing on the front of your teeth to remove the most obvious stains and film.

2. 2

   Drink water. Flooding your mouth with water as often as possible helps wash away bits of food, sugars, and other debris that builds up on your teeth throughout the day and causes them to look dull by the end of it. If you need a quick brightener, get a big glass of water and swish it around in your mouth before each swallow.

3. 3

   Eat an apple. When you bite into an apple it actually brightens your teeth by lifting off the film that can make them look dingy. Use your front teeth to bite into the apple, sinking them in all the way up to your gums. This is a good technique to use if you're out during the day and need a quick way to brighten your smile.

   • This technique works best with the freshest, firmest apple you can find. Use a tart apple instead of soft, sugary one.
   • Celery and pears can also help whiten teeth. They cause your mouth to produce a lot of saliva, which washes away stains and film.^[2]

   Chew sugarless whitening gum. Buy a pack from the drugstore and chew a few pieces during the day. The gum will remove bits of food from your teeth and temporarily brighten them up.

   Rinse with peroxide. Measure a few tablespoons of hydrogen peroxide into a cup, pour it into your mouth, and swish for one minute. Spit it out into the sink and rinse your mouth with clean water.

   • As an alternative, dip a cotton ball in peroxide and rub it on your teeth, making sure they get completely coated. Let it sit for about a minute, then rinse your mouth out with water.
   • Do not swallow the peroxide. It's safe to use peroxide on your teeth, but swallowing it could make you sick.^[3]
   • This technique should not be used often, as it may degrade your teeth over time. Use it when you need a quick whitening fix, but turn to more sustainable techniques in the long term.

1. 1

   Use teeth whitening strips, gels or rinses. Available for purchase at drugstores, these whitening products contain small amounts of peroxide to whiten your teeth. Follow the manufacturer's instructions for apply the strips or gels to your teeth. Rinses are used the same way you would use mouthwash. It usually take several applications before you see results.

   • Whitening strips and gels are not recommended for people with gum disease and other dental problems.^[4] Talk to your dentist before using these products if you're concerned.^[5]
   • Whitening strips and gels are best for people with a yellow tone to their teeth, and don't necessarily help remove darker stains.^[6]
2. 2

   Use a tray whitening system. Tray whitening systems, also available at drugstores or from a dentist, use a slightly more aggressive approach to whitening teeth. A concentrated peroxide solution is poured into teeth trays, which look like plastic retainers, and the trays are worn over the teeth for several hours.^[7]

   • Tray whitening systems may also be used overnight. Depending on how white you want your teeth to be, you can continue using tray whitening systems every day for several weeks.
   • Dentists may provide an at-home tray whitening kit. In some cases, the trays may be custom-made for your teeth using a mold so that they fit your teeth better than "one size fits all" trays.
3. 3

   Have your teeth professionally whitened. Many dentists offer whitening treatments that are very effective for removing dark stains. This is the most expensive technique, but it is also the quickest and offers the most dramatic results.

   • Lasers or heat are applied to the bleaching solution to make it work more quickly.
   • Depending on the level of staining, repeated dentist visits may be necessary, but each session lasts only about 30 minutes.

1. 1

   Stop smoking. Tobacco is one of the main culprits that causes teeth to become yellow or stained.^[8] The smoke fills the mouth and chemicals stick to the teeth. Try using a patch or an electric cigarette to avoid staining your teeth with smoke.

2. 2

   Drink less coffee, tea and other dark drinks. Coffee and tea both have ingredients that lead to stained teeth. If you drink them every single morning, they're bound to eventually leave their mark. Try cutting back to a single serving or removing them from your diet entirely.

   • When you do drink coffee or tea, brush your teeth afterward to remove the residue.
   • If you don't have a toothbrush or sink handy every time you drink coffee or tea, drink a glass of water afterward to rinse out your mouth.
   • Rinse your mouth after drinking fruit juice, wine, and other alcoholic beverages as well.^[9].
   • Have your drinks through a straw so you're less likely to stain your teeth.^[10]
3. 3

   Eat fewer sweets. Eating a lot of sugar is tough on your teeth and gums since it leads to the buildup of plaque and eventually cavities and gum disease. All these factors can make teeth look more yellow, so avoid eating candy and drinking soft drinks as often as possible. When you do eat sweets, brush your teeth or rinse your mouth out with water immediately afterward.^[11]

4. 4

   Go easy on your enamel. As we age, our the enamel on our teeth begins to erode; since the layer underneath isn't as bright, our teeth end up looking yellow in hue. Once the enamel is gone, it's difficult to get that youthful brightness back. Whitening your teeth too often can cause them to look bluish, so you can't rely on that as a backup forever.^[12] Prevent enamel erosion in the following ways:

   • Limit acidic foods, such as sour candy.
   • Treat acid reflux promptly.^[13]
   • Don't drink too much alcohol or practice other behaviors that lead to excessive vomiting.^[14]
