There are lots of great mouthwashes out there, and this list is by no means complete. We’ve included therapeutic mouthwashes you can buy over the counter and some that require a dentist’s prescription.
The active ingredient in this mouthwash is cetylpyridinium chloride (CPC), a broad-spectrum antimicrobial agent that’s effective against bad breath, tooth decay, and conditions such as gingivitis and receding or bleeding gums.
It’s alcohol-free so it won’t burn, making it a good choice if you have dry mouth or areas of irritation. Users say they like the minty aftertaste it leaves.
This product may temporarily stain your teeth, requiring strategic teeth brushing or regular cleanings at the dentist’s office. If you have sensitive gums and can’t stand the burning sensation caused by other mouthwashes, this negative may be worth the trade-off.
For a small number of people, the CPC ingredient may leave a taste in their mouth that they find unpleasant, or it may temporarily affect the way foods taste. In these cases, you may want to look at a different mouthwash.
This product is alcohol-free. It contains fluoride for fighting cavities and hydrogen peroxide for removing surface stains and whitening teeth.

Peridex prescription mouthwash
Peridex is only available by prescription, from a pharmacy or your dentist’s office.
Peridex is a brand of medicated mouthwash known generically as chlorhexidine gluconate oral rinse.
Prices vary based on your prescription plan. You may be able to purchase generic chlorhexidine gluconate oral rinse at a lower cost than the name brand.
Other brand names include Perisol, Periogard, and Paroex.
Peridex is a prescription germicidal mouthwash used to treat gingivitis and gum conditions, such as those that cause bleeding, swelling, and redness. It works by killing bacteria in the mouth.
Peridex isn’t right for everyone, and it may cause side effects, such as tooth staining, tartar buildup, mouth irritation, and a decreased ability to taste food and drink. It may also cause allergic reactions that are sometimes serious or life threatening in some people.
There are two types of mouthwashes: cosmetic and therapeutic.
Cosmetic mouthwashes control bad breath temporarily and leave a pleasant taste in your mouth.
Therapeutic mouthwashes include ingredients that provide long-lasting bacterial reduction and can be used for conditions such as receding gums, gingivitis, dry mouth, and plaque buildup. They’re available over-the-counter and by prescription.
What do you want your mouthwash for?
When choosing a mouthwash, the first thing to consider is your personal oral health goals.
- Bad breath. If your main concern is bad breath, using a cosmetic mouthwash on the go during the day may be sufficient for increasing your confidence during that important afternoon meeting.
- Dry mouth. If you’re taking medications or have a condition that produces dry mouth as a side effect, using a mouthwash designed to provide oral comfort for many hours at a time may be your best bet.
- Plaque or gum issues. Other conditions, such as plaque buildup, receding gums, and gingivitis can be addressed by choosing mouthwashes containing fluoride, or those with other active ingredients that fight bacteria.
- Price per ounce. Cost may be another factor to consider. Take a look at the price and the number of fluid ounces each bottle of mouthwash contains. Packaging can sometimes be deceiving. Buying larger bottles or in bulk can sometimes reduce the price per ounce, making the mouthwash cheaper in the long run.
- ADA Seal of Acceptance. Check the mouthwash label for the ADA Seal of Acceptance. It means that it’s been tested for effectiveness. Not every mouthwash has it, including some with well-known names.
It’s important to take a close look at the ingredient list. Many products have multiple ingredients geared to treat specific conditions or overall dental health. Some ingredients in mouthwash to look for include:
- Fluoride. This ingredient fights tooth decay and strengthens enamel.
- Cetylpyridinium chloride. This eliminates bad breath and kills bacteria.
- Chlorhexidine. This reduces plaque and controls gingivitis.
- Essential oils. Some mouthwashes contain compounds found in essential oils, such as menthol (peppermint), eucalyptus, and thymol (thyme), which have antifungal and antibacterial properties
- Carbamide peroxide or hydrogen peroxide. This ingredient whitens teeth.
Using the right mouthwash can support dental health and make your smile its most radiant. Mouthwash is able to reach parts of your mouth that brushing and flossing might miss, making it an effective tool for treating conditions such as:
Unless they’re designed specifically for young children, most mouthwashes are meant for those who are 6 years old and up. Children older than 6 who might swallow mouthwash should be supervised during their use.
Before purchasing mouthwash for your child, it’s a good idea to check with their dentist.
Mouthwash containing alcohol may not be suitable for people who are trying to avoid alcohol.
Mouthwash can be used to control bad breath and reduce cavities. It can also help to combat conditions such as receding gums, gingivitis, dry mouth, and plaque buildup.
Mouthwash should be used in addition to brushing and flossing. It’s important to use a mouthwash that has the ADA Seal of Acceptance.
