While most of us would like a brighter smile, figuring out which whitening treatment to use can be a process. If you find in-office treatments too expensive and at-home whitening kits too time-consuming, whitening mouthwashes might be just what you’re looking for. Not only do they remove surface stains with little effort, but these multitasking products also help kill bacteria and can freshen breath at the same time.  

Double board-certified dentist Dr. Rhonda Kalasho says whitening mouthwashes are safer to use than other whitening treatments since the “peroxide additive, such as hydrogen peroxide or carbamide peroxide, is at such a low concentration.” That means these mouthwashes will brighten your pearly whites without causing harm to the teeth and oral tissue.

Dr. Kalasho recommends using them “about 3 to 4 times a week, in conjunction with your regular fluoride-containing mouth rinse.” And as for how to choose a whitening mouthwash, she says to stick to options that don’t have alcohol in them, as those cause “a drying effect of the tissue, and therefore leads to dry mouth, which ultimately causes you to more likely develop decay and exacerbate tooth sensitivity.”

“Hydrogen peroxide may be present in the mouthrinse, but make sure it is at a safe and low enough concentration. The best whitening products also contain fluoride, which is wonderful at reducing tooth sensitivity and preventing cavities,” she added. 

Whitening mouthwashes are formulated to work over time with continued use, but if you find they aren’t brightening your teeth as quickly as you like, Dr. Kalasho says it is safe to use them at the same time as other whitening products. She also said they are a great way to upkeep the results of past whitening treatments, like higher-concentration gels, trays, and strips:  “Whitening mouth rinses keep everything fresher and brighter longer, and they preserve your whitening stride.”

The popular mouthwash is alcohol-free and safe to use twice a day. Hundreds of customers have given it their seal of approval, with one writing, “I used Scope mouthwash for years, but recently my dental hygienist suggested switching to a different mouthwash that was clear. I researched and decided to try this Solimo Amazon brand. I want to report after using this product for three weeks, I am shocked at how much whiter my teeth are. The difference is amazing. I have used professional whitening products in the past which did burn my gums, so at the moment I’m very happy with this Solimo product.”
