The Meetingpoint at Slavyanski.net - Dentafend Reviews https://slavyanski.net/sb2020/story.php?title=dentafend-reviews Toothpastes contain an agent that helps whiten and polish the teeth. However, they are generally mild and may not be as effective as other home whitening products. Pens usually contain a gel which contains hydrogen peroxide. The gel is applied to the teeth with a small brush at the end. The gel takes around 30 seconds to dry and is applied twice daily. Wed, 17 Aug 2022 15:27:13 UTC en
