If you swish with hydrogen peroxide everyday you will have the same results plus excellent gum tissue! Recommend swishing with peroxide for minutes morning and night. It kills bacteria that causes decay, gingivitis, periodontal disease. Worth a shot!
The grey would be cute with all the white you'll have.Then pops of color. If I could only have children, this would be the room. I love this Grey and white elephant nursery room theme; maybe add a pop of pink or yellow it would be perfect.
