Are you tired of dull and yellowing or stained teeth? Then you’ll love Lumineux’s whitening mouthwash, which will brighten your teeth while providing refreshing and effective cleaning. It’s made of non-toxic, natural ingredients to protect enamel and work with your body. In fact, Lumineux is the only oral care company whose products are certified non-toxic and microbiome-safe.

  • Alcohol-free formula saves mouth from burning
  • Pleasant taste
Product Cons

This fluoride- and alcohol-free mouthwash has a slightly sweet flavor, which combined with its light mintiness makes it easier to convince kids to use it (if its cool black color doesn’t convince them first). Plus, you get three bottles in each package, making it a great option for families.

Mouthwashes — A Buying Guide

The right mouthwash will help minimize bad breath and strengthen your teeth and gums by cleaning them properly. But how can you find the best one for you? It’s important to do your research on different mouthwashes to help you know what to look for, but if you’re still confused, don’t panic. Check out the tips below to find out what you need to consider when picking a mouthwash.

How to Select the Right Mouthwash?

You should thoroughly evaluate the following features before purchasing a mouthwash.

Active ingredients

Many of the most highly recommended mouthwashes contain fluoride as it strengthens teeth and prevents tooth decay. But be careful, as most fluoride-containing mouthwashes also contain sodium lauryl sulfate (SLS), which has been linked to cancer and other health problems.

Another active ingredient option that kills harmful bacteria is chlorhexidine gluconate (CHG) or triclosan. When used in mouthwashes, these chemicals act as anti-bacterial agents, helping to reduce plaque build-up and control bad breath.

Flavor

Choosing a fragrant and flavorful mouthwash is crucial as it will increase your confidence by eliminating your bad breath. While mouthwashes come in various flavors, the most popular one is mint. This refreshing flavor is the strongest, making it long-lasting and giving you pleasant breath all day.

Form

Mouthwashes come in various forms, such as liquid or gel varieties. Liquid mouthwashes are generally easier to apply and rinse off. Gel mouthwashes are thicker and usually contain alcohol, making your mouth dry. Both types offer similar benefits, although gels are better at keeping teeth fresh longer.

Effectiveness

A good mouthwash needs to be effective. For proof that mouthwash has undergone efficacy testing, look for the ADA Seal of Acceptance on the label. It will help you achieve your goal faster than non-tested mouthwashes.

Choose a Mouthwash According to Your Needs

Mouthwashes come in several varieties, each designed to target a specific issue. Here we’ve listed out a few that might stand out for you.

Bad breath

If your primary worry is your mouth’s foul smell, you should look for antiseptic mouthwashes. These options are designed to kill plaque and germs that lead to bad breath.

Dry mouth

A mouthwash that contains alcohol can increase the dryness in your mouth. Hence, using an alcohol-free mouthwash made to give oral comfort for several hours at a time is your best choice.

Plaque

Besides speeding up tooth decay, plaque buildup can contribute to other oral issues. Choose a mouthwash with fluoride or other active antibacterial agents to eliminate this oral hygiene antagonist. It will also help treat other diseases like bleeding gums and gingivitis.

Sensitive teeth

Having sensitive teeth can be pretty annoying! Always choose mouthwashes with compounds like calcium oxalate and hydroxyapatite, which help to desensitize and remineralize teeth. Potassium nitrate is another practical component you should look for in a mouthwash since it relaxes the nerves in your teeth.

Mouthwash vs. Toothpaste

While it is true that mouthwash and toothpaste are both important oral care products, both serve entirely different purposes. Toothpaste is intended primarily for cleaning and protecting your teeth, while mouthwash is used in conjunction with toothpaste to extend the effectiveness of tooth brushing and can be helpful for both tooth and gum health.

Mouthwashes and toothpastes often have different concentrations of fluoride and other ingredients, so it’s important to evaluate the contents of both, as well as any oral care concerns, to ensure you’re getting the best oral health benefits.

People Also Asked

What are the different types of mouthwashes?

There are two main types of mouthwashes: alcohol-based and non-alcohol-based. Alcohol-based mouthwashes are usually preferred because they provide better cleaning power. Non-alcoholic mouthwashes are less effective at removing stains from teeth and other surfaces, though they are a better choice for people with dry mouths.

Can children use mouthwash?

Children below the age of six should not use mouthwash at all, as swallowing the agent can have harmful effects. Children above six who are prone to choking should be supervised while using a mouthwash.

Should I rinse my mouth after using mouthwash?

No, it is recommended not to rinse your mouth after using mouthwash as it contains ingredients like fluoride, which take time to work. Rinsing your mouth with water will only eliminate beneficial ingredients, decreasing the cleaning agent’s potency.

How much mouthwash should I use at a time?

You should use about 20 milliliters of mouthwash, equivalent to around four small teaspoons or 2/3 of an ounce of liquid. Most mouthwash companies advise using mouthwash twice a day after cleaning your teeth.

What is the correct way to use a mouthwash?

For daily use, you should use your mouthwash after brushing your teeth and flossing. Gargle and swish it around your mouth for about 30 seconds, then spit it out, and do not rinse your mouth with water after using it.
