Mouthwash is also known as oral rinse.
A mouthwash or oral rinse is a liquid-based dental hygiene product that:
Many mouthwashes advertise a tingling sensation as a sign that the product is working.
However, for many people, using mouthwash does not feel refreshing. Instead, it may burn the mouth and feel painful.
It is possible to oral rinse products as directed and still experience a painful stinging or burning sensation. In most cases, this does not mean that you used the product wrong or you need to stop using it.
Not all mouthwashes cause burning. However, your level of sensitivity to certain ingredients may make it challenging to find a rinse that does not cause any burning.
Some mouthwashes are made without alcohol. Alcohol-free mouthwashes are typically more gentle on your tongue, mouth, and gums.

Most of the leading mouth rinse brands produce alcohol-free formulas.
If you switch to an alcohol-free mouthwash, but you still experience burning, you may be sensitive to one of the other active ingredients in the rinse. You may need to sample a few different formulas before you find a rinse that you like.
The different types of mouthwash include:
There are several reasons why your mouthwash may burn:
Alcohol contains antiseptic properties. It is a main ingredient in many mouthwash formulas. Alcohol kills bacteria and sanitizes your mouth.4
However, pure alcohol alone is not enough to kill bacteria, leading to bad breath and gingivitis. Alcohol is only one of the active ingredients in a mouth rinse.
Some oral rinses contain over 25% alcohol. When you use an oral rinse with alcohol, you may notice that the burning feeling centralizes on your tongue.
The taste buds on your tongue may be more sensitive to the taste and feel of alcohol than other areas in your mouth.
Another common mouthwash ingredient is chlorhexidine. This ingredient may reduce plaque and help fight gingivitis.1
Chlorhexidine may also result in a burning or tingling sensation.
The Food and Drug Administration has documented an uncommon but severe allergy that some people have to chlorhexidine.2

Some people are sensitive to menthol. This ingredient is derived from mint or peppermint.
Many people experience severe burning instead of a pleasant tingling when they use menthol mouthwash.
There are other ingredients typically included in mouthwash that may cause a burning sensation. These include:
If the mouthwash you are using causes ongoing burning symptoms or discomfort, stop use. You can also dilute it with water to reduce any burning.
Using a mouthwash that you are sensitive to can lead to a breakdown in some of the tissue in your mouth. This may contribute to ulcers.
