Top 7 Best Bad Breath Mouthwash Review 2023
Dentist Tested and Reviewed
Most mouthwashes you find at the store seek to reduce the microbial load in your mouth; however, other oral rinses treat dry mouth, oral fungus, bad breath, and oral pain.
A dry mouth can lead to bad breath, also known as halitosis, because it allows harmful bacteria to thrive.
Medications, autoimmune disease, or head and neck radiation can indirectly cause halitosis. Unfortunately, halitosis can be embarrassing and inhibit confidence and self-esteem.
Common Causes of Bad Breath
- Dental issues
- Mouth, nose and throat infections
- Dry mouth
- Smoking and tobacco
- Other chronic conditions

What we like
Dr. Katz developed a formula that works at reducing bad breath. Immediately you realize how comfortable it is to swish around. You forget you’re using mouthwash as it seems like you’re swishing with water. The mild mint flavor is just the right amount to be refreshing but not overpowering. After multiple days of use, morning breath was eliminated, guaranteed, or your money back. We were pleased with the overall effectiveness of this product.
What we don’t
The directions state to use one capful for 1 minute followed by another capful for 30 seconds of gargling. If you continued this regimen twice a day, you would need a new bottle every week. One option is to use one capful for one-minute swishing and gargling or half a capful for each.
2. TheraBreath PLUS Dentist Formulated Maximum Strength Oral Rinse
TheraBreath PLUS is an advanced formula that seeks to help people suffering from the most severe cases of halitosis.
Their original formula is fortified with soothing aloe vera and naturally antibacterial green tea, zinc gluconate, and tea tree oil. This is TheraBreath’s most robust bad breath-fighting oral rinse and is also helpful after eating odor-rich foods.

Best for patients with severe halitosis or consume odor rich foods
Directions
- Rinse mouth for 1 minute with one capful
- Gargle with another capful for 30 seconds to clean throat
- Wait 5 minutes before eating
- Use morning and night
What we like
As soon as you begin swishing, you realize this rinse has more kick than TheraBreath’s original oral rinse. The peppermint flavor is refreshing and more potent than the mild mint flavor. After you spit it out, you experience an icy sensation and a comfortable amount of tissue moistness. After using it for several days, it effectively eliminated bad breath and morning breath.
What we don’t
As mentioned before, the peppermint flavor was refreshing; however, it was slightly overpowering and seemed to irritate the gum tissue. Nevertheless, it eliminated a tingling and burning sensation after spitting it out. Also, we observed an altered sense of taste. Like the original formula, recommended 1.5 capfuls morning and night will quickly deplete the bad breath fighting oral rinse.
3. SmartMouth Original Activated Dual-Solution Breath Rinse
SmartMouth The Original Activated Dual-Solution Breath Rinse Mouthwash provides relief from the symptoms and discomfort of dry mouth.
SmartMouth dry mouth refreshes, moisturizes, rehydrates, cleans, and soothes oral irritation while lubricating oral dryness unlike any other mouth rinse out there. Utilizing patented zinc ion technology, SmartMouth delivers fresh breath for 12 hours with a single rinse.

What we like
SmartMouth has a refreshing mint flavor that sticks around for many hours after use. It effectively eliminates bad breath during the day and morning breath when you wake up. It has minimal burning along the inside of the cheeks and great aftertaste with no taste aversion. We were pleased with the overall comfort of this product.
What we don’t
One noted concern is a sense of dry mouth sensation after spitting it out. This doesn’t take away from its effectiveness; however, it’s an uncomfortable feeling for the oral tissue. Also, the bottle may leak if it’s shaken or tips over, so be aware of this when storing.

Best for patients with bad breath and dry mouth
Directions
- Shake well
- Swish 1-2 capfuls for 1 minute
- Use in morning and after meals
What we like
Oxyfresh mouthwash is different from all other products tested. Its lemon mint flavor is much sweeter than other rinses that are overpowering and uncomfortable to swish. However, it was comfortable and enjoyable to use. There was no burning, stinging, or dry mouth aftertaste. Also, it was effective at eliminating bad breath and leaving your mouth clean and refreshed.
What we don’t
One minor concern was that the lemon mint aroma reminded us of a chemical cleaning product flavor. It was difficult to shake this correlation from an otherwise impressive product.

Directions
- Do not swallow rinse
- Permitted for adults and children 12 years and older
- Vigorously swish 20 mL of rinse, twice a day for 30 seconds and then spit out
What we like
Philips has formulated a great product to combat halitosis and reduce plaque buildup. It has a strong mint flavor that will knock your socks off. In addition, it provides a lasting and effective refreshing taste after spitting out. This product pairs nicely when used with Philips Sonicare AirFloss Pro.
What we don’t
I would have thought this product contained alcohol because of how overpowering and intense the flavor was. Also, the aftertaste was bitter and left the mouth feeling parched and dry. We believe this product is best when paired with the AirFloss Pro because of its potency, which may be uncomfortable for daily use.
6. Oral-B Breath Therapy Mouthwash

Best for patients desiring bad breath relief with mild flavoring
Directions
- Swish thoroughly for one minute and spit out
- Not intended to be swallowed
- Refresh your mouth at any time of day
What we like
Oral-B Breath Therapy Mouthwash is a fantastic product that combines excellent flavor and comfortable relief. Mild mint is perfectly gentle and refreshing. There’s no burning, stinging, or unique aftertaste. In addition, they developed a great product that will suppress odor-causing bacteria. This product is almost identical to the TheraBreath original in regards to ingredients, taste, texture, and effectiveness.
What we don’t
The only concern may be how mild the mint flavor is for patients expecting a more flavorful rinse. Otherwise, Oral-B exceeded expectations with this product.

Directions
- Adults and children 12 years and older
- Rinse for 60 seconds with 15 mL morning and night
- Do not swallow
What we like
This multi-care mouthwash proves effective and refreshing. When you begin swishing, you feel the hydrogen peroxide foaming to kill bacteria and whiten your teeth. The icy fantastic mint flavor is enjoyable. After spitting it out, there’s no dryness, and your mouth is moist for many hours. The foaming sensation is a unique sensation.
What we don’t
Although this rinse has excellent flavor because it has alcohol, it burns and stings sensitive gums and tissue. As a result, it may be difficult for some individuals to tolerate for the full 60 seconds.
Overall Champion: TheraBreath Dentist Formulated Fresh Breath Oral Rinse*
There was a three-way tie between TheraBreath, Oral-B, and Oxyfresh. All three received high scores because of their effectiveness, non-burning, and refreshing flavor. Oxyfresh is different from the other two because of its sweet lemon-mint taste. This will be recommended if you find that desirable. TheraBreath edged out Oral-B because the mint flavor was slightly more pronounced and tasteful. However, you wouldn’t go wrong between these three great products.
Dr. Harold Katz created TheraBreath to help his daughter overcome her struggle with bad breath.
Since 1994, they’ve been creating oral care products that treat halitosis, gum disease, tooth decay, stained teeth, immune support, tooth sensitivity, and dry mouth.
The original TheraBreath formulation attacks odor-causing bacteria rather than masking it with heavy flavors or powerful odors. TheraBreath Oral Rinse stimulates saliva flow and circulates antibacterial, oxygen-rich bacteria throughout your mouth.
