How to Use Custom-fit Whitening Trays at Home Safely

Are you feeling self-conscious about your yellowing teeth? Do not worry. It is a common issue that many people face. Luckily, there is a simple solution to restore the brightness of your smile: custom teeth whitening trays.


What Are Custom Teeth Whitening Trays?

Are you familiar with mouthguards for sports? Custom-fit teeth-whitening trays work similarly. Filled with a whitening gel to target stubborn stains, they are specifically made to fit your mouth. Some tray systems require application by a dentist or at home, but all start with a custom dental fitting to create the trays.


How Do Custom Teeth Whitening Trays Function?

The process of using custom teeth-whitening trays is effortless. Your dentist will take impressions of your teeth to create molds that fit your teeth perfectly. Once you have the trays, fill them with bleaching solution and wear them for up to four hours a day for one to two weeks. You will see a noticeable improvement in the whiteness of your teeth within that period.


How to Use Them


  • Get a Custom-fit Tray

Utilizing custom-fit whitening trays requires having them made by a dental expert as the first step. The expert will take a mold of your teeth to create a tray that fits comfortably and snugly against your teeth. Your dentist will send you home with a tray and a highly concentrated whitening gel.


  • Apply the Whitening Gel 

Before applying the gel, ensure your teeth are free of any food or debris. After that, add a tiny bit of whitening gel to each well in the tray. Avoid overfilling the tray to avoid the gel leaking and irritating your gums. The whitening gel's high concentration guarantees that you will see results after just a few applications.


  • Put on the Tray

Place the tray over your teeth and gently press it against your gums to create a tight seal after adding the gel. You should wear the tray for 30 to 60 minutes. You might feel a little sensitive, but this is normal and will pass after a few days. You can use the tray while doing other things, like reading or watching TV. However, be careful not to eat or drink anything that might stain your teeth.


  • Remove and Rinse the Tray 

Remove the tray from your mouth after the recommended time and give it a good rinsing with water. After that, rinse your mouth with water to remove any remaining gel. The gel is harmless and nontoxic, but it is crucial to follow the directions to prevent any potential irritation.


  • Safely Store the Tray

It is crucial to store the tray properly to ensure it lasts as long as possible. Keep the tray out of the sun and extreme temperatures and in a dry location. The tray will remain intact for use the next time you want to whiten your teeth.



Using specially-made whitening trays is a practical and efficient way to whiten your teeth. You can safely and effectively whiten your teeth at home by following these instructions and speaking with your dentist if you have any questions. Custom-fit whitening trays are a great option to consider, whether you want to increase your confidence or enjoy a brighter smile.
