- Read the instructions on the gel and tray you purchase so you know exactly how the product should be used. Some trays should be worn for a few hours a day while others are worn every night.
- Squeeze the recommended amount of peroxide gel onto the whitening tray. Insert the trays into your mouth. Place them into your mouth and gently close your mouth. The gel that is included with these rays is carbamide peroxide instead of hydrogen peroxide. Hydrogen peroxide is the kind of gel used in a dental office and it is activated with a lamp. The carbamide peroxide does not require a lamp. If you feel extra gel running over your teeth, wipe it away. Remove the trays after the required amount of time has passed.
- While this method is effective for most people, some users report teeth sensitivity and sore gums as a result. If you have these side effects, cease use and talk to your dentist about whether the product is safe for you.

- Read the instructions before using your whitening strips. The duration the strips are left on and how to apply varies from product to product. Some strips actually dissolve so they do not require removal but still it would be best to avoid swallowing your saliva during the procedure. Remember that any whitening substance has a certain amount of toxicity.
- Be careful when applying the strips. The hydrogen peroxide can burn hands and gums. Do not leave the strips on longer than recommended, as this can cause gum sensitivity and a burning sensation in the mouth. Check your gums in the mirror to see if there are any changes that usually look like white lines over the gum line. You can also breathe through your mouth or try drinking a bit of cold water to check your teeth sensitivity.
- This method is best used if you're not trying to white teeth fast as it can take up to a few weeks to work.

Method 2
- Use baking soda and hydrogen peroxide. When combined with water, baking soda releases free radicals that break down molecules that cause stains and ultimately leads to a whiter smile. Making a simple toothpaste at home, using baking soda and hydrogen peroxide, can help whiten your teeth.
- Combine baking soda with hydrogen peroxide, using slightly less baking soda. Mix into a fine paste that is not too gritty.
- Brush the paste onto your teeth. Let it stand for about a minute and then rinse your mouth with water or mouthwash. If any of the paste remains on, brush your teeth again with an over the counter toothpaste.
- Do not use this paste more than two or three times a week as excessive use of baking soda can actually break down tooth enamel and cause soreness and tooth decay.
- Make sure to counter the abrasive effects of baking soda by using fluoride toothpaste once a day and leaving it on for two minutes before rinsing.
- Try apple cider vinegar. Apple cider vinegar, especially when used with baking soda, can remove stains from teeth. You can make a whitening paste of two parts apple cider vinegar and one part baking soda. Use this paste to brush your teeth 2 to 3 times a week and you can expect to see results in a few weeks.
- Experiment with peppermint leaf and coconut oil. Peppermint leaf and coconut oil, available for purchase at many health stores, can be used to whiten teeth. You can mash up a few leaves of peppermint into a few tablespoons of coconut oil and use this as a paste for your teeth 2 to 3 times a week. While consensus in the dentist community is still out, some of the chemicals found in coconut oil could potentially lighten teeth and also remove bacteria and prevent new stains from attaching on the tooth surface. Some people have found this method effective for them personally.
