Best whitening mouthwash

If you’re considering a whitening mouthwash, it’s a great idea. They’re easy to use, easy to get and cheaper than whitestrips or gel procedures. And they care for the 80% of mouth surfaces your toothbrush doesn’t reach!  But, even if you’re focusing on whitening, the choice is overwhelming. How do you decide which whitening mouthwash is best for you?

Each whitening mouthwash works in different ways or is formulated to meet additional needs. To make the best choice think about why you are trying to whiten your teeth and what other aspects of oral health matter to you.

We’ve hand-picked and reviewed a selection of the best whitening mouthwashes on the market to help you brighten your smile.

But before we get to the products, there are three absolutely fundamental questions you must consider first. Do this and you can be sure to find a whitening mouthwash that really works for you. These are:

  1. Does mouthwash make teeth whiter?
  2. How do whitening mouthwashes work?
  3. Is whitening mouthwash bad for your teeth?

1. Does mouthwash make teeth whiter?

This is a great question. The whitening ingredients in whitening kits have to be held against the teeth for at least 30 minutes in order to work. So how can a mouthwash which is only in your mouth briefly actually whiten your teeth?

Whitening mouthwashes can help to brighten your smile. But it’s important to understand how they work and have realistic expectations.

Whitening mouthwashes can help to:

✔ Shift and prevent external stains (from products such as tobacco or coffee)

✔ Reduce plaque and tartar that discolor your teeth

✔ Make your teeth as white as they once were by strengthening tooth enamel

Maintain your smile after in-office whitening or the use of DIY whitening kits

But they cannot:

X Lighten your teeth beyond their natural shade (which is known as intrinsic whitening).

Intrinsic whitening can only be achieved by systems that hold peroxide against the teeth for a prolonged period.

2 How do whitening mouthwashes work?

Our selected brands base their products on one or more of the methods below. Understanding them will help you match the right product to your needs. If you love red wine, you will be focusing on stain removal. If your teeth have become discolored through thinning enamel, you will be on the hunt for an enamel strengthening mouthwash.

Stain removal

  • Some whitening mouthwashes contain ingredients such as hydrogen peroxide to lift stains.
  • Others use ingredients that ‘loosen’ or break down stains such as sodium hexametaphosphate.

Stain prevention

  • This is achieved through ingredients that bond with your teeth to prevent future stains developing.
  • These include pyrophosphate.

Enamel strengthening

  • Reinforcing tooth enamel prevents yellow dentin showing through.
  • Ingredients such as fluoride will be used for this purpose.

3. Is whitening mouthwash bad for my teeth?

Potentially harmful Ingredients in mouthwash, such as hydrogen-peroxide, are at very low concentrations. This means they are very unlikely to harm teeth, gums or mouth tissues.

However, different people have different tastes, sensitivities and tolerances. It is possible that you may experience tooth or gum sensitivity or burn when using any mouthwash, whitening or otherwise. And rinses containing alcohol can increase sensitivity by drying out the mouth.

For good measure, our selection includes alcohol free and natural rinses. They also address other issues like sensitivity, bleeding gums or the need to source ethical natural products. So whatever your particular need, you should find a mouthwash to boost the brilliance of your smile here.
