I've found professionally made trays to be the best, safest and most comfortable. The laser method is tricky and can make your teeth an unnatural color. The store-bought strips and gels are good for minor staining, or for maintaining whiteness from another method. If your dentist makes a tray for you from a mold taken from your own teeth, the gel put into the mold gets into every angle and space in your teeth, while avoiding getting on your gums, so you don't end up with white teeth on red, irritated gums. The professional tray method is obviously more expensive than the store-bought method, but is less expensive than the laser. I have sensitive teeth, and now I also have a bright smile!
