Crest Pro-Health Multiprotection Mouthwash
Price: $
The active ingredient in this mouthwash is cetylpyridinium chloride (CPC), an all-around antimicrobial agent meant to lessen bad breath, tooth decay, and conditions such as gingivitis and receding or bleeding gums.
It’s alcohol-free so it shouldn’t burn, making it a solid 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 that contain alcohol, 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.
Pros
- contains antimicrobial agents
- made to fight bad breath
- may help reducing gingivitis
- alcohol-free
Cons
- may leave an unpleasant aftertaste

This mouthwash lists xylitol as an inactive ingredient. Xylitol increases the amount of saliva in the mouth and reduces S. mutans bacteria, which cause plaque to form on teeth.

There are two types of mouthwashes: cosmetic and therapeutic.
Cosmetic mouthwashes control bad breath temporarily and are meant to leave a pleasant taste in your mouth.
Therapeutic mouthwashes include ingredients designed to 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.
Other considerations
- 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 is known to fight tooth decay and strengthen enamel.
- Cetylpyridinium chloride. This is meant to eliminate bad breath and kill bacteria.
- Chlorhexidine. This is meant to reduce plaque and control 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 is meant to whiten 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:
- bad breath
- gingivitis
- plaque
- dry mouth
- yellow or discolored teeth
- receding gums
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. The ADA does not recommend mouthwash for children younger than 6 years of age.
Mouthwash containing alcohol may not be suitable for people who are trying to avoid alcohol.
Should I rinse after mouthwash?
No. Mouthwash contains helpful ingredients, such as fluoride, that need time to work. Rinsing immediately after use washes away the ingredients you’re using a mouthwash for.
Which mouthwash kills bacteria the best?
No mouthwash will kill 100 percent of the bacteria in your mouth. Look for a mouthwash that kills 90-99 percent or more of bacteria. There are several brands.
Which mouthwashes do dentists recommend?
The American Dental Association’s (ADA) Seal of Acceptance appears on many brands of mouthwash, including all of the brands on this list. You can see the ADA’s full list of approved mouthwashes here.
Mouthwash can be used to control bad breath and reduce cavities. It can also help to improve 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.
