Yes, antiseptic mouthwashes can kill both good and bad bacteria. For this reason, use is recommended only once daily.
Mouthwash is a liquid oral hygiene aid that eliminates bacteria and freshens breath. Mouthwash is often used in conjunction with brushing and flossing. Therapeutic rinses containing essential oils or cetylpyridium chloride (CPC) can reduce plaque and gingivitis by roughly 20%. These mouthwashes, however, cannot remove a ardened calculus or be a substitute for daily brushing and flossing. Mouthwash can eliminate the bacteria that are on the surface of the teeth. Using mouthwash at a different time than brushing may help to retain the benefits of your toothpaste.
Mouthwash mainly removes the surface stains on the teeth. Studies support that the addition of essential oil non-alcohol-containing mouthwash to the brushing and flossing routine further reduces plaque, gingivitis, and bleeding [1] (Bosma et al., 2024). Brushing and flossing are able to clean into the periodontal pockets, which prevent gum disease. The biofilms that are in your mouth are adherent and attach to the surface of the teeth. Brushing physically removes these biofilms. Furthermore, flossing physically removes the biofilm that is between the teeth. If the bacteria are not initially disrupted with brushing and flossing, the mouthwash cannot penetrate the plaque enough to be able to kill the bacteria underneath.
Not all bottles of mouthwash are created equal. If you are browsing the aisles at the Lantana Place H-E-B, here is what you should be looking for to ensure you get the most out of your mouthwash.
Essential Oil Mouthwashes vs Antibacterial mouthwashes: Medical literature discovered that after 6 weeks of mouthwash use, subjects who used CPC and Essential oil mouthwashes showed significant reductions in all gingival and plaque measurements compared to subjects using non-antibacterial mouthwashes [3] (Elias et al., 2015).
Gum disease occurs when the bacteria penetrate below the gumline and harden into tartar. Once plaque transforms into tartar, no liquid can dissolve tartar without destroying the teeth as well. Mouthwash can provide a feeling of freshness and reduce surface-level bacteria, but the overall effects are superficial. Mouthwash can clean the mouth, but it cannot penetrate deep enough to fight gum disease. Professional periodontal therapy, such as scaling and root planing maybe required to cure gum disease. Here at Enamel Dentistry Lantana in Oak Hill, we offer both scaling and root planing to cure gum disease.
Here at Enamel Dentistry Lantana, we advise our patients to consider using mouthwash after lunch or snacks. This boosts your pH levels and removes food particles before they set in. If you use mouthwash immediately after brushing, you might be rinsing away the fluoride from your toothpaste. Try to wait approximately 20 minutes after brushing before rinsing. The alternative is a fluoride-based mouthwash so that you are notdiluting your protection.
Below is a table that compares mechanical cleaning vs chemical rinsing
Method | Primary function | Plaque removal | Annual cost | Reaches gum pockets? |
Brushing | Scrubbing surfaces | High | Low | No |
Flossing | Cleaning between the gaps | High | Low | Yes |
Mouthwash | Reduce the amount of bacteria | Low | Low | No |
Professional Cleaning | Remove tartar | High | Covered by insurance | Yes |
A typical bottle of mouthwash can cost about $8 at the store, but treating advanced gum disease can cost significantly more. Prevention is a great financial strategy. Most dental insurances cover your preventive cleanings at 100%. Using mouthwash is a great low-cost addition to your oral hygiene routine. But, should never replace the representative care that saves you thousands in the restorative work later.
Yes, antiseptic mouthwashes can kill both good and bad bacteria. For this reason, use is recommended only once daily.
No, if you rinse with water immediately after spitting out your mouth, you wash away the active ingredient, like fluoride.
Whitening mouthwashes contain very low levels of hydrogen peroxide. While they can help maintain brightness and remove surface stains from coffee and tea, they are not nearly as effective as professional whitening
