- 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.
Brush and floss your teeth thoroughly. This will help remove any build-up that will prevent your teeth from being whitened, and it will also help to maintain the results of whitening your teeth for longer. Flossing your teeth will remove plaque in between your teeth and will ensure that this area is whitened as well. Also be sure to get your gums, too.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 often 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.
- Try to avoid swallowing while you are whitening your teeth to avoid ingesting the whitening chemicals.
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.
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.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.
- You can also brush your teeth with a fluoride toothpaste after you finish the treatment. This will help to protect your tooth enamel.
- If you use the right strips correctly, you'll be able to maintain the results for up to four months.
Method 2Using Whitening Gel or Toothpaste
- 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.
- Whitening gels do not use a strong bleaching agent, so sensitivity is unlikely.
- 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.
- 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.
- Use the toothpaste just as you would use any other toothpaste, brushing your teeth for at least two minutes and then rinsing your mouth.
Method 3Whitening Your Teeth with 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.
- Purchase a bottle of hydrogen peroxide from your local drugstore. 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 and weak enough so it won’t cause sensitivity.
- 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, but this will not taste good. Some people dislike this method because of the bad taste.
- Spit out the solution, and rinse your mouth with water.
- Brush your teeth as you normally would.
- 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:
- Pour 2 teaspoons (10ml) of hydrogen peroxide into 3 teaspoons (15ml) 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 and always use a soft toothbrush.
- 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.
