3. Setup and Custom Fitting
The Oral-B Nighttime Dental Guard is designed for a custom fit at home. Follow these steps carefully for optimal results.

- Prepare the Guard: Open the package and remove the guard, impression tray, and storage case.
- Heat the Guard: Place the guard within its impression tray into a microwave-safe bowl. Fill the bowl with water to cover the guard. Microwave for approximately 1 minute (adjust based on microwave wattage; lower wattage may require slightly longer). The guard should become soft and pliable.
- Mold the Guard: Carefully remove the tray from the microwave. Allow it to cool slightly so it's warm but not scalding. Place the softened guard (still in the impression tray) into your mouth. Bite down firmly to create an impression of your teeth. Hold this position for about 2 minutes to allow the guard to begin setting.
- Cool and Set: Remove the guard and tray from your mouth. You may place it in a bowl of ice water for 5 minutes to help it harden and retain its shape.
- Remove from Tray: Gently separate the molded guard from the green impression tray. Be patient and gentle during this step to avoid damaging the guard. If it's difficult to remove, soak it in ice water for a bit longer.
- Test Fit: Insert the molded guard into your mouth to check for a comfortable and snug fit. It should feel secure but not tight.
Important: If the guard does not fit correctly or feels uncomfortable, you can reheat it in the microwave (for slightly less time than the initial heating) and repeat the molding process. The guard is designed to be remolded.
4. Usage and Operation
Once custom-fitted, the Oral-B Nighttime Dental Guard is ready for use.
Wearing the Guard:
- Insert the guard into your mouth before sleeping.
- The guard works by creating a barrier that prevents direct contact between your upper and lower teeth, even if it does not extend to cover your molars. This separation helps to reduce the impact of grinding and clenching.
- It may take a few nights for your mouth to adjust to wearing the guard. Initial symptoms like increased saliva or minor discomfort are common and usually subside.

Duration of Use:
The Oral-B Nighttime Dental Guard is designed to be wearable for up to 6 months. Replace the guard if it shows signs of wear, damage, or if it no longer fits securely.
5. Maintenance and Care
Proper care of your dental guard will ensure its longevity and hygiene.
Cleaning Instructions:
- After each use, rinse the guard thoroughly with cold water.
- Do not use hot water, as it can deform the guard.
- Do not use toothpaste to clean the guard, as some types may damage the material.
- Gently dry the guard with a paper towel or a clean cloth.

6. Troubleshooting
If you encounter issues with your Oral-B Nighttime Dental Guard, refer to the following common solutions.
Common Issues and Solutions:
- Guard Does Not Fit Properly:
- If too loose or too tight, reheat the guard in the microwave for a slightly shorter duration than the initial fitting. Repeat the molding process (Section 3).
- Ensure you bite down firmly and hold the position during molding.
- Difficulty Removing Guard from Tray:
- Soak the tray with the guard in ice water for an extended period (e.g., 5-10 minutes) to ensure it is fully hardened.
- Gently pry the guard from the tray using a non-sharp object, such as a plastic floss pick, being careful not to damage the guard.
- Increased Saliva or Discomfort:
- This is common during the initial adjustment period. Continue wearing the guard; these symptoms typically subside within a few nights.
- If discomfort persists or worsens, re-evaluate the fit or consult a dentist.
- Guard Falls Out During Sleep:
- This indicates an improper fit. Reheat and remold the guard, ensuring a snug impression.
- Ensure the guard is fully hardened after molding by cooling it sufficiently.
