Ask a General Dentist: Are There Any Risks to Using Mouthwash?

Mouthwash, or mouth rinse, is commonly recommended by general dentists to add to an at-home oral hygiene routine. These rinses help eliminate harmful bacteria in the mouth that can cause decay, gum disease, and bad breath. However, some individuals have concerns that mouthwash can harm their oral and overall health.

Mouthwash: what is in it?

There are several types of mouthwash available at pharmacies and drug stores that target different oral health concerns. The ingredients of each vary depending on its use and may include:

• Alcohol
• Fluoride
• Peroxide
• Essential oils
• Flavoring and dyes

Additionally, some general dentists may prescribe mouthwash containing stronger ingredients to target gingivitis, dry mouth, oral sores, or dry socket.

The benefits of mouthwash

When used as directed, these products can provide benefits that complement a thorough oral hygiene routine. For example, mouthwashes that contain fluoride can help strengthen enamel and protect against tooth decay. It also reaches every area of the mouth, touching spaces that may be hard for individuals to reach with their toothbrush or floss. While mouthwash should never replace brushing and flossing, it can help remove bacteria that people might otherwise miss.

Potential drawbacks of mouthwash

Stains teeth

According to a review published in Therapeutic Advances in Drug Safety, one of the most common side effects of mouthwash use is teeth staining. Mouthwash containing chlorhexidine (CHX), which is only available by prescription, is more likely to cause temporary discoloration after the individual uses it. Mouthwashes that contain bright dyes are also more likely to cause staining than dye-free options.

Kills healthy bacteria

Just like healthy bacteria in the gastrointestinal system, there are also healthy bacteria in the mouth, known as the oral microbiome. This bacterium helps keep people healthy, breaking down nutrients and regulating blood pressure. They can also protect against inflammation. Unfortunately, overusing antibacterial mouth rinses can kill the good and bad bacteria in the mouth.

Causes dry mouth or irritation

Excessive use of mouthwash may introduce avoidable issues. Some formulas contain up to 25 percent alcohol, which can contribute to dry mouth. High amounts of alcohol in mouthwash formulas can also irritate soft tissues. Individuals with higher oral sensitivity may experience burning sensations, sensitivity, or redness.

How to safely use mouthwash

It is important for patients to use mouthwash in moderation. These products are designed to help, not replace, brushing and flossing. A rinse used once or twice a day is generally enough for most individuals.

However, some people may overuse mouthwash. Signs of mouthwash overuse include:

• Chronic or inflamed canker sores
• Bleeding gums after using mouthwash
• Symptoms of dry mouth
• Pain or sensitivity
• Stained or discolored teeth

If these symptoms appear, patients should reduce or stop using the mouthwash and contact their dentist for professional guidance.
