Starting point
I have relatively sensitive teeth, which were not very yellow, but where coffee, red wine and co. had left their mark. In particular, the canines were affected
Application and Tips
The application is very simple. The whitening strips are each adhesively bonded to the upper and lower row of teeth. There they will have one hour to act. My 4 tips to:
1. Toothpaste: I have found me a precaution a toothpaste for sensitive teeth and brush with it before and after applying my pearly whites. I had no problems with pain or sensitivity in spite of my rather sensitive teeth.
2. Lip Care: The whitening gel is inevitable in the course of the application to / on the lips, which these can be extremely dry. I am now gone over generous einzucremen my lips with lip balm immediately after sticking the strip and have since no longer a problem with dry lips.
3. teeth dry: To adhere the strip better and stay right where they are, I dry before using my teeth off with a tissue. The stripes do I place then exactly on the teeth or make sure that as little gums as possible to come into contact with this. This also saves unnecessary irritation.
4. double strip number: Who, like me, not very has big teeth that can strip simply cut in half lengthwise and then receives double the number of stripes (the remaining part, which is otherwise folded on the tooth back, so can also be used for the front side). This has worked for me excellently. You can also go small for most discolored teeth bit "tailoring" and so whiten individual teeth.
I am really convinced and will equal more order me a pack for occasional refresher of my smile.
