There are various in-office teeth whitening options to choose from (Zoom whitening, Britesmile, Lumibrite, Opalescence, etc.), each of which ranges somewhat in price. Costs for in-office treatment may also depend on the dentist performing the treatment. That said, the national average cost of in-office teeth whitening is approximately $650.
I have read, but can not substantiate, that urine can be kept in a cool room temperature environment for 24 hours. Refrigerating and/or freezing can kill the bacteria that the urine test is supposed to detect and unless recommended by your doctor is not something you want to do.
Yes. A urine sample home-test should be 89.6 - 98.6 Fahrenheit (32-37 Celsius). If the pee is too hot or too cold, the test will be deemed invalid and the test will show b â¦ lank (N/A). This will cause whoever is demanding you to take the test, to know that you either faked it with someone's urine, that is not yours.
