Is it Bad to Use Mouthwash?

Daily oral care is essential for a healthy mouth. Every day we eat food that can get stuck between our teeth and/or gums, sugary drinks that can damage teeth or certain foods that cause tooth decay and then problems with infections.

Therefore, you should always brush your teeth after every meal with a brush that's adapted to your mouth and toothpaste that suits your needs: for sensitive teeth, whitening, anti-gingivitis, and so on. And then, mouthwash. In this OneHowTo article we explain whether or not it's bad to use mouthwash.

Steps to follow:

The first thing you should know about mouthwash is that, without prior tooth-brushing, it's useless and it should be kept in the mouth for at least one minute.

But if we use it correctly, it helps maintain healthy teeth by removing any bacteria that may be inside of the mouth. It also gives you fresh breath, leaving you with a pleasant freshness. They are highly recommended for problems like gingivitis, helping it to disappear.

So, is it bad to use mouthwash? The answer is no, but we must take certain things into account, because problems may arise if we don't use it properly. This is why we recommend you read our article on how to care for your teeth properly.


A mouthwash containing alcohol should only be used between once and twice a day at most, because alcohol causes dehydration, and gives the feeling of dry mouth. So you can use it, but in moderation. Always check the ingredients of the product before buying it.


For cases of gingivitis, chlorhexidine is often recommended, a different component. For this type of mouthwash you should use it every day, every time you brush your teeth, for a month. Don't use it for longer than this, as stains may appear on the gums or tongue caused by chlorhexidine. So always read the ingredients and/or active ingredients of the product.


Mouthwashes indicated for whitening teeth usually contain bicarbonate. You should check this, and if so, don't use it for more than a month and only use it once a day. Bicarbonate whitens immediately but it cannot be used on a daily basis. Therefore, if your original color comes back, you should stop using the treatment for a few months before starting it again.

The best advice, in general, is to use mouthwashes that don't contain alcohol. They do not cause a dry mouth and can be used after each brushing. It is also easier to keep them in your mouth for a minute. It is best to use it twice a day (except for specific treatments) and switch brands every year so that the mouth does not become immune.
