I must say, no risk of that with the Crest Pro-Health Invigorating Clean Multi-Protection Rinse. I stand behind my assessments made at the beginning after just using the product a few days. I and am pleased with the clean feeling that remains after some other oral products’ effects have worn off and you lose that fresh breath, clean mouth feeling.
Crest has some great product info here, but I can tell you for my own part, using the product once in the morning and once at night has made me less concerned about my breath and general oral health and boosted my confidence. I know that I am doing more than just brushing and flossing. To paraphrase a line from the product fact sheet: When I rinse, it helps me feel confident that I am taking the right steps to ace my next dental check-up.
