Rinsing your mouth with an effective mouthwash can remove debris and help fight cavities, gum disease, and bad breath.
Some mouthwashes are specifically designed to target certain issues, such as halitosis (bad breath), dry mouth, or tooth stains.
Mouthwashes have active ingredients in low concentrations to effectively address these issues without causing dental health issues. They’re combined with inactive ingredients like water and flavoring agents.

According to Dr. Aggarwal, you should look for the following ingredients in a quality mouthwash:
Note: A mouthwash doesn’t need to contain all of these ingredients to be effective.
Dr. Aggarwal recommends avoiding mouthwashes containing alcohol (not including xylitol or sorbitol) or sodium lauryl sulfate (SLS).
Mouthwashes containing alcohol can cause a burning sensation. Alcohol also dries out your mouth, which can be a contributor to the development of cavities.
SLS is a surfactant and detergent found in many household and cosmetic products. When used in mouthwash, it can irritate your gums. Dr. Aggarwal says this can even lead to gum peeling and ulcers.
Best Overall Mouthwash
Dr. Khushbu Aggarwal, one of NewMouth’s in-house dentists, recommends Crest Pro-Health Multi-Protection as an optimal overall mouthwash.
Its active ingredient is 0.07% cetylpyridinium chloride (CPC), an antiseptic compound. CPC kills oral bacteria and is effective at reducing gingivitis and plaque formation.1
It may cause temporary surface staining in a small number of people. According to Crest, this is caused by a buildup of dead bacteria on the teeth.2 It can be removed through good oral hygiene and visiting the dentist regularly.
Best Whitening Mouthwash
Crest 3D whitening mouthwash was shown in one study to noticeably whiten teeth.3 It contains hydrogen peroxide, which acts as a mild bleaching agent.
This mouthwash is alcohol-free, so it won’t sting or dry out your mouth. It will also freshen your breath. However, it doesn’t target plaque or cavities.
ACT Anticavity mouthwash contains a high concentration of fluoride, which can help prevent cavities. ACT also offers alcohol-free and whitening formulas of their cavity-fighting mouthwash.
This mouthwash is also available in different flavors, including mint and cinnamon. ACT Anticavity also has a bubblegum flavor intended specifically for kids. However, Dr. Aggarwal cautions that some flavors may be too strong for some people.
Best Mouthwash for Bad Breath
This mouthwash is specifically formulated to fight bad breath using sodium chlorite, an oxidizer.
Bad breath is caused by anaerobic bacteria, which means they thrive without oxygen. TheraBreath kills those bacteria by providing oxygen.
TheraBreath is also vegan, kosher, and gluten- and alcohol-free.
Best Mouthwash for Dry Mouth
Biotène Dry Mouth Oral Rinse is alcohol- and sugar-free. It contains xylitol and sorbitol (both sugar alcohols), which moisturize the mouth, encourage saliva production, and provide a sweet flavor. Xylitol also helps fight oral bacteria.
This mouthwash uses glycerin as a moistening agent. However, this also gives it a “thick texture that may not be palatable for some,” according to Dr. Aggarwal.
Best Mouthwash for Sensitive Teeth
CloSYS Ultra Sensitive mouthwash is designed for sensitive mouths. The pH-balanced formula contains only four ingredients:
This mouthwash comes flavor-free, with optional natural oil droppers that let you decide the flavor strength. It’s also ADA-approved for reducing bad breath.4 However, Dr. Aggarwal notes that CloSYS is “on the more costly side.”

Best Mouthwash for Gum Disease
Dr. Aggarwal recommends Listerine Ultraclean for fighting gum disease. Listerine products generally use antibacterial and antifungal compounds derived from essential oils. These include:
These compounds have strong minty flavors and are often used in food and drinks. They’ve also been shown to be effective at reducing the germs that cause plaque and gingivitis.5
Listerine Ultraclean comes in both alcohol-containing and alcohol-free formulations. However, Dr. Aggarwal warns that the compounds used in Listerine may cause a temporary burning sensation in the mouth, with or without alcohol.
