How to Get Whiter Teeth at Home

White teeth are a sign of health and good self-care and they're essential for a lovely smile. If your teeth aren't as white as you'd like them to be, there are some things you can do to get whiter teeth at home. While none of these suggestions will work in the same way as a professional whitening service, they can help whiten your teeth and won't cost a fortune. Just remember to talk to your dentist before you try any at-home remedies to make sure they won't damage your teeth. If you want to know how to make some lifestyle changes as well as to try some at-home treatments for whitening your teeth, just follow these steps.

Steps

Use Whitening Strips

1. 1
   Find the appropriate whitening strips. They should be approved by the American Dental Association (ADA) and shouldn't contain chlorine dioxide, which can actually damage your enamel. Whitening strips should be made of polyethylene and you can find them at your local drugstore or even a supermarket.
   
   
   
   
   • There will be two strips -- one for your lower teeth and one for your upper teeth. Each will be lined with a gel that will help the strips adhere to your teeth.
   • The average cost of whitening strips is about $30.
2. 2
   Thoroughly brush and floss your teeth. This will help remove any build-up that will prevent your teeth from being whitened. Flossing your teeth will remove plaque in between your teeth and will ensure that this area is whitened as well.
   
   
   
   
3. 3
   Study the instructions. Each package of whitening gel is slightly different, so check out the instructions to see how to apply the strips, how long to leave them on, and how oftn they should be used. Most strips are used for about half an hour twice daily. Some have to be thrown out after they're used while others will simply dissolve in your mouth.
   
   
   
   
4. 4
   Apply the strips over your teeth. Apply the strips firmly over your teeth, running your fingers over the strips to help the gel stick to your teeth. Avoid moving your tongue too much or you'll get gel all over your mouth. This won't be harmful, but it can feel a little unpleasant. Leave the strips on your teeth for the given amount of time on the instructions.
   
   
   
   
5. 5
   Remove the strips. After the right amount of time passed, gently remove the strips from your teeth and throw them out. If they dissolve, you can skip this step.
   
   
   
   
6. 6
   Rinse your mouth. Rinse it thoroughly until you have removed the remaining gel from your mouth. Continue using the whitening strips for the amount of time that is recommended in the instructions, and wait to see the results.
   
   
   
   
   • If you use the right strips correctly, you'll be able to maintain the results for up to four months.

Use Whitening Gel or Toothpaste

1. 1
   Use whitening gel. Find an ADA-approved gel to use on your teeth and read the instructions to understand the process of using a whitening gel. Then, brush the gel onto your teeth with a small brush, just as you normally would -- for at least two minutes. Then, spit out the remaining gel and rinse out your mouth until the gel is gone.
   
   
   
   
   • Continue using the whitening gel twice a day for fourteen days, or for however long the product is recommended on the instructions. You'll see results in just a few days.
2. 2
   Use whitening toothpaste. Make sure the toothpaste is ADA approved before you purchase it. ADA-approved whitening toothpastes whiten your teeth by gently removing their surface stains through polishing, chemical chelation, or other processes that do not require bleach. You can find many of these toothpastes over the counter. [1]
   
   
   
   
   • Use the toothpaste just as you would use any other toothpaste, brushing your teeth for at least two minutes and then rinsing your mouth.

Whiten Your Teeth with Hydrogen Peroxide

1. 1
   Use hydrogen peroxide. Commercial whitening kits aren't cheap; for a cheaper solution, you might like to consider whitening your teeth at home using hydrogen peroxide for a similar effect. Bleaching teeth with hydrogen peroxide is acknowledged as a safe practice by the American Dental Association.
   
   
   
   
2. 2
   Purchase a bottle of hydrogen peroxide from your local drug store. Hydrogen peroxide is commonly used to treat skin wounds, but its antiseptic properties are also good for oral hygiene. Hydrogen peroxide is typically packaged in a brown bottle. The opaque packaging keeps light from altering the makeup of the solution. Buy a 3% solution, which is safe for oral use.
   
   
   
   
3. 3
   Use a mixture of the hydrogen peroxide and water as a mouthwash. Use it daily before you brush your teeth to whiten your teeth naturally. Make sure to mix it in a 50/50 solution with water. Here's how you should do it:
   
   
   
   
   • Pour about 2 tablespoons (30 milliliters) of the antiseptic into your mouth, and swish it around for 1 minute. The solution will begin to foam; this is how you know it is working. The hydrogen peroxide combined with oral bacteria cause bubbles to form in your mouth.
   • Spit out the solution, and rinse your mouth with water.
   • Brush your teeth as you normally would.
4. 4
   Brush your teeth with a hydrogen peroxide and baking soda paste once a week. This mixture will help keep your teeth looking white and clean. Here's how you can make it:[2]
   
   
   
   
   • Pour 2 teaspoons (10 milliliters) of hydrogen peroxide into 3 teaspoons (15 milliliters) of baking soda. Mix these together until a paste forms. Play with these measurements until you find a consistency that you like. The paste should be similar in thickness to toothpaste.
   • Add a tiny bit of mint toothpaste to your homemade paste to give it a fresh flavor. You can also add a drop of peppermint extract.
   • Mix in a dash of salt. The salt will exfoliate your teeth as you brush. However, salt is quite abrasive, so don't use it too often.
   • Dollop the paste mixture onto your toothbrush.
   • Brush the paste onto your teeth in small, circular motions. Once all teeth are covered, let the mixture sit on your teeth for 2 minutes.
   • Rinse the solution off your teeth by swishing with water from the bathroom sink.
   • Brush your teeth with toothpaste to rid your mouth of any remnants of the hydrogen peroxide mixture.

Whiten Your Teeth with Baking Soda

1. 1
   Wet your toothbrush and dip it into baking soda. All of the bristles should be covered with water so that your toothbrush bristles are white.
   
   
   
   
2. 2
   Brush your teeth for 2 minutes. Spit if necessary.
   
   
   
   
3. 3
   Spit out the baking soda. Rinse your mouth clean with water (you don't want baking soda in your mouth for a long period of time). Using mouthwash after can help to remove the bad taste of the baking soda if it is unbearable. Use this method once or twice a week for the best results.
   
   
   
   
   • If you experience any tingling after using baking soda in your mouth, see your dentist. It may indicate tooth decay.
   • Overusing this method can cause damage to the enamel that coats your teeth. Talk to your dentist about how often you should be trying this.[3]
4. 4
   Add lime or lemon juice to the baking soda. This involves adding the juice of a lime or lemon to the baking soda:[4]
   
   
   
   
   • Squeeze the juice from 1/2 a lemon or lime.
   • Mix the fresh juice with a 1/4 cup of baking soda. Expect a little bubbling.
   • Dab a damp cotton wool ball or corner of a clean face washer cloth into the mixture. Rub the mixture over the teeth, making sure to get it into the gaps and corners near your gums, and right down to the ends of each teeth. Also rub the backs of the teeth.
   • Leave for one minute then immediately brush off. Don't leave it too long as it is acidic and can wear away your precious pearly whites.
   • Use once weekly or less often. Over time, you should see some whitening results.

Make General Changes

1. 1
   Avoid foods or beverages that stain your teeth. Where possible, you may be able to prevent further staining by making some lifestyle changes. This includes stopping all smoking, and reducing your consumption of tannin-containing beverages –– soda, coffee, red wine and tea all contain tannins.[5] In some cases, you can help keep tannin drinks away from your teeth by drinking them with a straw (do not drink hot liquids through a straw).
   
   
   
   
2. 2
   Eat natural teeth helpers. Some foods can actually help you keep your teeth white. Here are a few of them:[4]
   
   
   
   
   • Eat more apples, celery and carrots. They're like a fruit and veggie toothbrush for the teeth and they help increase the production of saliva in your mouth, removing plaque.[5] As an added bonus, their high levels of vitamin C help to kill off odor-causing bacteria and strengthen your gums.
   • Eat more strawberries. They contain a natural astringent (malic acid), which helps to lift stains. To get the most benefits, consider rubbing half a strawberry over your teeth or mashing the strawberry and applying it to your teeth. Leave for one minute, then rinse clear.[5]
   • Rinse with a glass of half lemon juice and half warm water once a week. This will lighten your teeth. Don't do it more than once a week though, as the lemon juice can erode teeth too.[5]
   • Eat more hard cheese. It helps to increase saliva production in the mouth, thereby removing the bacteria that stains teeth.[5]

Maintain Healthy Dental Habits

1. 1
   Brush your teeth twice a day. While brushing and flossing won't remove existing stains, good mouth hygiene is essential to preventing more staining and to keeping your teeth in excellent shape. The first most useful thing you can do is to brush your teeth regularly, to remove plaque, pieces of food and drink residue. Plaque will attack your teeth and gums if left in place and brushing (in conjunction with flossing) helps to disturb its ability to grow.
   
   
   
   

   
   • Brush after breakfast and before going to bed. This is a minimum; many people also like to brush after lunch and even after snacks, especially if they are sugary snacks.
2. 2
   Floss daily. Floss is the most effective way for you to remove plaque build-up from in between your teeth and near the gums. With plaque removed, your teeth will appear much cleaner and therefore brighter.
   
   
   
   
   • Floss at least once a day. A good time is at night, after brushing and before going to bed.
   • Experiment with different types of floss until you find one that works best for you. Some floss types may be too rough, too slippery or too flavored for you, so keep looking for one you do like.
3. 3
   Gargle with mouthwash. Mouthwash kills bacteria and can contain elements aimed at strengthening your teeth. Used along with brushing and flossing, mouthwash can help reduce the bacteria, kill bad odors and keep your teeth healthier and cleaner.
   
   
   
   
   • As with floss, not all mouthwashes are the same. Experiment with different types until you find a mouthwash you like and that leaves your teeth and gums feeling fresh.
4. 4
   Schedule regular dental appointments. Have your dentist clean your teeth professionally at your regularly-scheduled appointments. This will help you maintain good dental hygiene, spot any cavities, and keep white, healthy teeth. Remember to talk to your dentist before you try any teeth whitening product to make sure that it won't hurt your teeth.
   
   
   
   
   • If you have very sensitive teeth and gums, or crowns or some other dental work that won't react well with a whitening product, your dentist will know.
   • Serious teeth darkening is usually best remedied by professionals.
