Truth About Mouthwash: 70% of People Get It All Wrong

With the relaxation of mask-wearing rules, many people are now concerned about bad breath. To manage the primary cause of bad breath, which is oral bacteria, it’s essential to maintain oral hygiene. Mouthwash plays a vital role in providing immediate relief, especially in situations where brushing isn’t possible. Given the wide range of mouthwash products available, finding the one that suits you best is worth exploring.

From luxury to necessity

While mouthwash is considered a necessity these days, there was a time when many people viewed it as a luxury. Back then, people believed brushing with a toothbrush and toothpaste was sufficient—some even diluted mouthwash with water due to its distinct minty flavor.

Use Mild Products for Sensitive Mouths

Some people may experience a burning sensation after using mouthwash. This can be more pronounced in individuals with higher stress levels or severe fatigue. If you feel your mouth is more sensitive than others, opt for a mild mouthwash without added ethanol when purchasing.

Portable Sprays for On-the-Go Freshness

Consider using mouthwash sprays if you can’t gargle due to specific situations like meetings or conferences. They typically come in compact containers (10-15 ml) that easily fit in your pocket, making them highly portable. The essential advantage is the convenience of freshening your mouth anytime, anywhere. The tiny water droplets penetrate deep into your mouth, providing immediate refreshment.

Do You Need to Rinse After Gargling?

Is it necessary to rinse your mouth with water immediately after gargling with mouthwash? The answer is, “It’s not necessary.” Rinsing your mouth immediately after gargling may dilute the mouthwash’s disinfectant and antibacterial properties as it mixes with the water. This effect can reduce the concentration of sterilizing and antibacterial ingredients. The same principle applies even when gargling after dental treatments.

Exceptions to the Rule

However, some individuals find rinsing with water after gargling more suitable. This mainly applies to those aged 65 or older or taking hypertension medication. These groups often have reduced saliva secretion, which is crucial in protecting the oral mucosa. When they use mouthwash, the disinfectant ingredients can sometimes irritate the mucosa. In such cases, rinsing with water is recommended to alleviate the discomfort.

Wait 30 Minutes Before Eating

After using mouthwash, waiting about 30 minutes before consuming food is advisable. This is particularly important if you plan to have coffee, cola, wine, or other substances that can potentially cause tooth discoloration. Some mouthwashes contain ethanol, which, if consumed immediately after gargling, could influence the results of a breathalyzer test. So, be cautious!

You Still Can’t Skip Brushing

Using mouthwash as a substitute for brushing is common when brushing isn’t feasible. However, it’s essential to remember that mouthwash alone cannot replicate the effects of brushing. If you neglect proper brushing, plaque, a leading cause of tooth decay, will accumulate over time and harden into tartar. While mouthwash can assist in removing some plaque, managing tartar buildup requires the mechanical action of brushing.

Overusing Mouthwash Can Worsen Bad Breath

Using mouthwash excessively or in large quantities may exacerbate bad breath instead of alleviating it. The alcohol content in mouthwash can evaporate along with moisture, leading to dryness in the mouth. Dryness can increase the risk of developing oral health issues like bad breath. Additionally, certain mouthwashes contain chemicals that, when combined with toothpaste, can lead to tooth discoloration.

Summer Requires Extra Care

During hot and humid summers, paying extra attention to oral health is crucial. The prolonged heat can lead to increased consumption of foods irritating the teeth, such as ice cream or carbonated beverages. Neglecting proper brushing can contribute to bad breath. To maximize the effectiveness of mouthwash, it’s best to wait at least 30 minutes after brushing before using it. Using mouthwash immediately after brushing can reduce its effectiveness as the ingredients interact with toothpaste.

Utilize Expired Mouthwash for Cleaning

Expired mouthwash can be repurposed for sterilizing toothbrush heads. Pour mouthwash into a cup and soak the bristles of your toothbrush for 2-3 hours. Afterward, remove it and let it air dry. This process can help eliminate impurities and bacteria from the toothbrush. Dipping a cleaning brush into mouthwash can make cleaning bathroom walls or sinks with mold and stains more manageable.
