Why Does Mouthwash Burn?

Mouthwash is designed to help freshen your breath and kill the bacteria that cause bad breath. Mouthwash takes some time to work, so you must use it regularly.

The main reason mouthwash can burn is because it is made using alcohol or menthol to clean the bacteria in your mouth says this dependable dentist in Greenville. Both ingredients can cause a burning sensation in your mouth.

If you are experiencing a burning sensation when using mouthwash, it might be because you are using too much. It is best to follow the directions on the bottle, or else your mouth will get irritated more quickly.

There are also other reasons why your mouthwash might be burning your mouth.

Types of Mouthwash

There are two types of mouthwash: one that simply cleans your mouth and one that helps fight bacteria and dental plaque.

The first type is generally better for people who have a toothbrush with a tongue cleaner, as the tongue cleaner can remove debris between teeth that a toothbrush can’t reach.

However, if you don’t have a tongue cleaner, the second type is a much better option.

Good Breath

Some people think that by using mouthwash, they will get rid of bad breath. This isn’t true. Mouthwash only masks bad breath; it doesn’t get rid of it completely.

The best way to get rid of bad breath is by brushing your teeth and flossing regularly and eating healthy foods while avoiding foods that are known to cause bad breath, like garlic or onions.


Some brands contain fluoride, which has been known to help strengthen tooth enamel if used correctly (and not too much).

Fluoride can be found in most regular toothpaste brands, so look for ones with fluoride in them (recommended levels are 0.15% – 0.3%). If you want the extra boost from your mouthwash, make sure it contains fluoride!


Cosmetic mouthwash is a type of mouthwash used for cosmetic purposes. It is not meant to heal any oral health problems, but it is often marketed to improve oral hygiene.

Many types of mouthwash are marketed for their ability to whiten teeth, freshen breath, or fight the appearance of plaque and tartar.

Some people use mouthwash to remove plaque and tartar if they have dental problems, leading to gum disease. Cosmetic mouthwashes often contain ingredients such as alcohol, chlorhexidine, triclosan, benzalkonium chloride, menthol, peppermint oil, or eucalyptus oil.


Therapeutic mouthwash is often prescribed by dentists to help reduce periodontal disease, plaque, and bad breath. The most common ingredients in therapeutic mouthwash are sodium fluoride, chlorhexidine gluconate, and zinc chloride.

The sodium fluoride helps to re-mineralize tooth enamel while also inhibiting bacterial growth on the surface of the teeth. The chlorhexidine gluconate prevents bacteria from sticking to the teeth while also killing some strains of bacteria.

Zinc chloride kills bacteria that cause odor-producing sulfur compounds. Therapeutic mouthwash is typically used twice a day or as directed by your dentist.

Using Mouthwash with Menthol

Mouthwash with menthol causes your mouth to burn. This is because menthol stimulates the nerves in your mouth to activate, causing irritation and discomfort. Try using a mouthwash without menthol.

Using Mouthwash with Alcohol

Mouthwash with alcohol also causes an unpleasant taste in your mouth. Most alcohol-based mouthwashes contain a high percentage of alcohol because it’s the only way that they can clean your teeth properly.

Alcohol, however, is also a very strong-tasting substance. If you’re not a fan of this taste, try using a mouthwash without alcohol to see if that works for you.

If you find that the burning sensation is too much for you to handle, talk to your dentist about other options.

Using Mouthwash with Artificial Sweeteners

Artificial sweeteners have been linked to dental erosion and other oral health issues in the past and they’re not particularly great for your health in general either.

These sweeteners are designed to mimic real sugar without contributing additional calories or carbohydrates to your diet, but they come with their own side effects that are just as bad as the negative effects caused by real sugar consumption.

Dental Issues

Some people have dental problems that are so severe that they need mouthwash to help them. If you have a dental problem, your dentist will likely recommend mouthwash to help with the problem.

For example, if you have gingivitis, your dentist may recommend mouthwash to prevent the infection from spreading. Mouthwash is also recommended for people who brush their teeth twice a day and still experience plaque buildup.

Mouthwash can also be used for temporary relief of enamel pain or sensitivity caused by tooth decay or injury.

What Should You Not do After Using Mouthwash?

Mouthwash is a common tool for fighting bad breath and plaque buildup. It may come as a surprise to some, but after using mouthwash you should not rinse with alcohol or eat or drink anything.

Alcohol dries out the mouth and food and liquids can lead to bacteria growth.

When Should You Not Use Mouthwash?

Mouthwash should not be used when you have an infection in your mouth or an ulcer or cold sore. This is because the mouthwash may contain ingredients that can irritate your mouth.

It’s important to get advice from your dentist or doctor before using mouthwash because some types can be harmful.

Mouthwash can also reduce the amount of saliva in your mouth, which can cause problems if you have dry mouth.

Who Shouldn’t Use Mouthwash?

  • Children under six years of age – there is a risk of choking.
  • Anyone who has had oral cancer – there is a risk that the mouthwash may irritate the area and increase the risk of cancer coming back.
  • Anyone who has had an ulcer in their mouth, or who has an ulcer-like condition where they are more likely to bleed (this is called hemorrhagic diathesis). There is a risk that the mouthwash will irritate the ulcer, causing it to bleed and get worse. Mouthwashes containing alcohol may also make these problems worse. If you have this type of condition, use sugar-free gum instead – it helps to stop bad breath without irritating your mouth or making you more likely to bleed.

Final Thoughts

Mouthwash can be a great way to fight bad breath and maintain perfect dental health. However, it is important to make sure you are using it correctly.

Mouthwash should be used after brushing your teeth and rinsing with water, not before! It is also important to make sure you rinse the mouthwash before you spit it out.

This will ensure that all of the benefits of the mouthwash are not wasted in the sink.
