Bleaching and non-bleaching products are the two basic kinds of whitening products available today.
Non-bleaching products normally use abrasives or chemicals and only remove surface stains on teeth.
Bleaching products work with a chemical called peroxide and can brighten your teeth several shades.
Another process employs the use of a special gel that is placed inside a flexible device you wear around your teeth for a certain period of time. After you remove the device, you must use a second bleaching agent, followed by a special light to activate the chemical action.
Mildly stained teeth usually only require one session of bleaching.
The BERLIN Sleeping Car travels by being added to Amtrak trains. The Map of Amtrak routes gives you an idea of the possible train vacation destinations that you may wish to consider when planning your itinerary. The BERLIN Sleeping Car may be chartered by a family, group of friends, corporate travel or any combination you desire. When you charter your private railcar, you create your own luxury railcar trip. You determine where you want your private railcar excursion to go - which route you want to take - and how long you wish to stay at your "train vacation destination."
