Listerine, especially essential oil varieties, helps manage plaque and gingivitis (early gum inflammation) as an adjunct to brushing and flossing, but it cannot cure periodontitis (advanced gum disease). Periodontitis involves bone and tissue loss, requiring professional treatments like deep cleanings, which mouthwash alone can't fix, though specific Listerine products (like Advanced Defence) can support treatment by preventing bacterial attachment.
The Quick Answer: Listerine as Adjunctive Plaque Control
The formula helps manage the bacteria that cause early-stage gum inflammation. However, it is important to understand that mouthwash is not a comprehensive periodontitis treatment and cannot correct underlying structural damage or severe infection.
Mouthwash isn't a substitute for regular brushing, and it won't cure gum disease. But, for some people it may be a helpful addition to their daily oral hygiene routine. The best way to know for sure if mouthwash is necessary and the best one for you, is to talk to your dentist or periodontist.
The active ingredient in Crest Peroxyl mouthwash is hydrogen peroxide, clinically-proven to kill disease-causing bacteria. Hydrogen peroxide is an excellent preemptive measure against periodontal disease, as it can help to reverse gingivitis and prevent gum disease from progressing.
In addition to professional care, you can take several steps at home to help shrink gum pockets:
Reversing Periodontitis and Advanced Periodontitis
Early periodontal disease can be treated with a minimally-invasive deep cleaning procedure. This involves scaling – more thorough than a standard cleaning – followed by root planing under local anesthetic to remove tartar and plaque beneath the gum line.
Dentists often don't recommend routine mouthwash because it can disrupt beneficial oral bacteria, cause dry mouth (especially alcohol-based types), mask underlying issues like bad breath, and potentially lead to tooth staining or taste changes, with brushing and flossing remaining the core of good oral hygiene, though prescribed rinses can be useful for specific, short-term conditions.
If periodontitis isn't advanced, treatment may involve less invasive procedures, including:
The good news is that mouthwash, along with other at-home oral care routines and regular cleaning and check-up visits with your dentist, can significantly reduce the risk of periodontal (gum) disease and consequent gum recession.
Brush your teeth twice a day, in the morning and at night. Use a toothbrush with soft, rounded-end bristles and a head that is small enough to reach all parts of your teeth and mouth. Replace your toothbrush every 3 to 4 months. Use a fluoride toothpaste.
Common Mistakes to Avoid with Periodontal Disease
Inconsistent Oral Hygiene: Neglecting a proper oral hygiene routine, including regular brushing, flossing, and professional cleanings, can worsen periodontal disease. Consistent oral care is essential for managing and preventing the progression of the disease.
The ADA Council on Scientific Affairs' Acceptance of Listerine Antiseptic is based on its finding that the product is safe and has shown efficacy in helping to prevent and reduce gingivitis (and plaque above the gumline), when used as directed.
However, the National Health Service (NHS) recommends avoiding mouthwash right after brushing, since this may wash away the fluoride from your toothpaste. Instead, the NHS recommends using mouthwash at a different time of day.
Your dentist may recommend using a prescription mouthwash that contains chlorhexidine, a topical antiseptic. It helps destroy harmful bacteria in your mouth. People who use chlorhexidine rinses may develop temporary side effects, such as a change in taste or dental staining.

Proper oral hygiene is the first line of defense against periodontal bacteria. Regular brushing, flossing, and professional dental cleanings help remove plaque and tartar, thereby reducing the bacterial load in your mouth. Using an antibacterial mouthwash can also kill bacteria and freshen your breath.
The 2-2-2 rule in dentistry is a simple guideline for good oral hygiene: brush twice a day, for two minutes each time, and visit your dentist twice a year, helping to prevent cavities, gum disease, and other dental problems by establishing consistent habits for plaque removal and professional monitoring.
Periodontal disease isn't life-threatening. But it can lead to other health conditions that may require treatment, especially if the infection spreads to other areas of your body. Gum disease isn't curable. But it's manageable with proper treatment.
Commercial mouthwashes such as Listerine have an acidic pH that may cause harm to the enamel if used too frequently. It is also important that you limit the duration of contact between the mouthwash and your teeth.
Looking to bolster your daily at-home oral hygiene routine? Adding LISTERINE® to your daily regimen can help reduce early gum disease.
Don't rinse your mouth immediately after brushing, as it'll wash away the concentrated fluoride in the remaining toothpaste. Rinsing dilutes it and reduces its preventative effects.
How to Shrink Gum Pockets Naturally at Home: A Few Tips
If you have gingivitis, which is the earliest form of gum disease, you'll likely notice inflamed, red, swollen, and bleeding gums. In this stage, the infection is still reversible. In contrast, periodontitis is a far more severe condition characterized by deep pockets that form in between teeth.
In extreme cases, periodontal pockets can reach 10mm or deeper, and at this point, will likely need to be treated with surgical treatments, like gum grafting, laser gum surgery or flap surgery.
