Why Does Expiry Matter?

Expired whitening strips can lose effectiveness, potentially causing uneven whitening or no whitening at all. Beyond ineffectiveness, using expired products might also lead to oral irritation or sensitivity due to the breakdown of ingredients over time. To ensure both safety and optimal results, knowing whether your whitening strips have expired is vital.

How to Determine If Whitening Strips Are Expired

1. Check the Expiry Date

The most direct way to determine expiration is by checking the packaging for an expiry date. Manufacturers are required to include this, so always inspect the box or pouch before use.

2. Assess the Packaging

Examine the packaging for any noticeable wear or damage. Compromised packaging may affect the strips' integrity, leading to premature expiration.

3. Look for Changes in Texture and Color

Whitening strips that have darkened, become sticky, or show any discoloration may have expired. These changes indicate the active ingredients have degraded.

4. Observe the Smell

Off-putting or unusual smells from the strips could signal expired ingredients, rendering them ineffective or unsafe.

5. Evaluate Past Performance

If previously effective strips exhibit diminished results, it's possible they have passed their expiration, resulting in reduced whitening capability.
