Teeth whitening trays are an essential component of many at-home whitening kits. They allow for the effective application of whitening gel to the teeth, ensuring that the gel remains in contact with the enamel for optimal results. Properly shaping these trays is crucial for achieving the best whitening effects while also ensuring comfort during use. This article will provide a detailed overview of how to shape teeth whitening trays, including the materials involved, the step-by-step process, tips for success, and post-shaping care.
What Is Teeth Whitening Trays?
Teeth whitening trays are custom-fitted devices made from a flexible material designed to hold whitening gel against the teeth. They are often referred to as “boil and bite” trays because they can be softened in hot water and molded to fit the unique shape of a person’s mouth.
This customization is essential for maximizing the effectiveness of the whitening treatment and minimizing the risk of gel leakage, which can lead to gum irritation.
Types of Teeth Whitening Trays
There are two primary types of teeth whitening trays:
Custom-Made Trays: These trays are created by dental professionals based on impressions of the patient’s teeth. They offer the best fit and comfort but can be more expensive and time-consuming to obtain.
Boil and Bite Trays: These are commercially available trays that can be molded at home. They are typically less expensive and more accessible but may not provide as precise a fit as custom-made trays.
Materials Used for Teeth Whitening Trays
Teeth whitening trays are usually made from a thermoplastic material that becomes pliable when heated. Common materials include:
Polyethylene: A lightweight and flexible plastic that is commonly used for boil and bite trays.
EVA (Ethylene Vinyl Acetate): A more durable and elastic material that offers better retention and comfort.
Step-by-Step Guide to Shaping Teeth Whitening Trays
Shaping teeth whitening trays involves a straightforward process that can be done at home. Follow these steps for the best results:
Step 1: Gather Your Materials
Before you start, ensure you have the following materials:
Teeth whitening trays (boil and bite type)
A pot or kettle for boiling water
A bowl for cooling water
A pair of scissors for trimming the trays
A towel for drying your hands and the trays
Step 2: Boil Water
Begin by boiling water in a pot or kettle. Once the water reaches a rolling boil, remove it from the heat source and allow it to cool for a few seconds. The water should be hot but not boiling when you immerse the trays.

Step 3: Soften the Trays
Carefully place one tray into the hot water for about 6 to 10 seconds. Make sure to hold the tray by the tab to avoid touching the sides, which may fold over. The tray should become soft and pliable but not too hot to handle.
Step 4: Mold the Tray
Once the tray is softened, quickly remove it from the water and place it over your upper teeth. Use your fingers to press the tray firmly against your teeth, ensuring it covers all surfaces. You can also use your tongue to help mold the tray against the back of your teeth. Bite down gently to create an impression of your teeth in the tray.
Step 5: Set the Shape
After molding the tray, remove it from your mouth and immediately place it in a bowl of cold water for about 10 to 15 seconds. This will help set the shape of the tray, allowing it to retain the impression of your teeth.
Step 6: Trim the Tray
Once the tray has cooled and set, you may need to trim it for a better fit. Use scissors to carefully cut away any excess material around the gum line or the tab. Be cautious not to cut too much, as you want the tray to fit snugly without causing discomfort.
Step 7: Repeat for the Lower Tray
Follow the same process for the lower tray. Soften it in hot water, mold it to your lower teeth, set the shape in cold water, and trim as necessary.
Tips for Successful Tray Shaping
Practice Makes Perfect: If your first attempt at shaping the tray is not satisfactory, don’t worry. You can reheat the tray and try again until you achieve the desired fit.
Avoid Overheating: Be careful not to leave the trays in the hot water for too long, as they can become too soft and lose their shape.
Use Cold Water: Always use cold water to set the shape of the tray after molding. This helps to lock in the impression of your teeth.
Check for Comfort: After shaping, wear the trays for a few minutes to ensure they are comfortable. If they cause discomfort or pressure points, you may need to trim them further.
Follow Instructions: Always refer to the specific instructions provided with your whitening kit, as different products may have unique requirements.
Post-Shaping Care for Teeth Whitening Trays
After successfully shaping your teeth whitening trays, proper care is essential to maintain their integrity and effectiveness:
Clean the Trays: Rinse the trays with cold water before and after each use to remove any residual gel and bacteria. Avoid using hot water, as it can warp the trays.
Store Properly: Keep the trays in a cool, dry place when not in use. Consider using a protective case to prevent damage.
Avoid Direct Sunlight: Prolonged exposure to sunlight can degrade the material of the trays, so store them away from direct light.
Replace When Necessary: If you notice any signs of wear or damage, such as cracks or tears, replace the trays to ensure effective whitening.
