Crest 美白加 Scope 持久清新牙膏

The Scope flavor really lasts through my morning coffee and then some—I notice the fresh taste hours later. It leaves my teeth feeling noticeably cleaner after just a few brushings.

The taste is definitely milder than other whitening toothpastes I've tried, but the freshness from the Scope really does seem to last for hours after brushing.

I’ve been using this for a week and my morning coffee breath doesn’t come back until lunch—the 7x longer freshness claim actually holds up in my experience. The paste itself isn't too harsh, and the Scope flavor is just right without being overpowering.
