Why Does Mouthwash Burn?

The Burning Sensation

March 13, 2024 Written By: Joyce Kahng, DDS

Have you ever experienced that fiery sensation in your mouth after swishing around your mouthwash? It’s almost like a rite of passage in our daily oral hygiene routine.

But have you ever wondered why mouthwash burns? When that tingling sensation kicks in, some may wonder if it’s a signal that the mouthwash is doing its job, while others might question if it hints at an underlying issue.

The Burning Sensation: Ingredients

The primary culprits behind that tingling or burning sensation are usually alcohol and menthol, which are common ingredients in many mouthwash formulations. Alcohol is known for its disinfectant properties, helping to kill bacteria that cause bad breath and dental plaque. However, it’s also notorious for causing a burning sensation in sensitive mouth tissues. Menthol, on the other hand, adds a refreshing feel and smell to the mouthwash but can also contribute to discomfort.

Alcohol: A Double-Edged Sword

Alcohol-based mouthwashes are effective in combating oral bacteria, but they can be pretty harsh, especially for those with sensitive mouths or certain oral conditions. The alcohol content can lead to dryness and irritation in the oral mucosa, making your mouth more susceptible to sores and infections.

Menthol: Refreshing Yet Potent

Menthol is derived from mint oils and is added to mouthwash for its cooling effect and pleasant scent. While it does make your mouth feel fresher, it can also irritate sensitive tissues and lead to a burning sensation during and after use.

Other Factors at Play

It’s not just the ingredients that can cause mouthwash to burn. Other factors that contribute to this sensation include:

Oral Health Conditions

If you’re suffering from gum disease, mouth ulcers, or other oral health issues, your mouth’s sensitivity to mouthwash ingredients can increase, leading to discomfort. In these cases, the burning sensation serves as a signal to reconsider your choice of mouthwash.

Overuse: Less Is More

Believe it or not, using too much mouthwash or using it too frequently can exacerbate the burning sensation. Overuse can disrupt the natural balance of your mouth’s microbiome and irritate the oral tissues, making them more prone to burning and discomfort.

Finding Relief: Choosing the Right Mouthwash

Realizing that the burning sensation can be a deterrent to maintaining good oral hygiene, it’s essential to find a solution that keeps your mouth healthy without discomfort. Here are some tips for choosing and using mouthwash more comfortably:

Opt for Alcohol-Free Formulas

Alcohol-free mouthwashes have gained significant popularity in recent years due to their gentle yet effective approach to maintaining oral health without the potential harsh side effects associated with alcohol-based products. These innovative formulations not only help in reducing the burning sensation often experienced but also offer a soothing and thorough cleansing experience, promoting overall oral hygiene and freshness.

Consider Natural Alternatives

Natural mouthwashes bring a holistic touch to oral hygiene, blending soothing ingredients like aloe vera and chamomile with essential oils such as tea tree oil. Together, these enriching elements create a gentle, super-effective solution for oral health. By adding these natural options to your routine, you can enhance your oral care, enjoy more comfort, and lower the chances of irritation.

Follow Instructions Carefully

Adhering to the recommended amount and duration of mouthwash use is crucial for maintaining oral health. By following the instructions on the product label and not exceeding the suggested time, you can effectively reduce discomfort and promote a healthy mouth. Overusing mouthwash or prolonging its contact in your mouth may lead to increased irritation and a burning sensation and potentially disrupt the natural balance of oral flora. It’s essential to use mouthwash as directed to reap its benefits without any adverse effects.

Consult Your Dentist

If switching mouthwashes doesn’t alleviate the burning sensation or if you have specific oral health concerns, it’s wise to consult your dentist. They can recommend a product that suits your needs or investigate underlying conditions that may be contributing to the discomfort.

FAQs About Mouthwash and Burning Sensation

Q. Can mouthwash cause long-term damage to oral tissues?

In general, no. However, overusing or using a mouthwash with harsh ingredients can lead to dryness and irritation and potentially damage oral tissues in the long term. It’s best to choose a gentle, alcohol-free mouthwash and use it as directed.

Q. How does mouthwash contribute to good oral health?

Mouthwash can help eliminate bacteria and freshen your breath, but it’s not a substitute for brushing and flossing. It should be used as part of a comprehensive oral hygiene routine to maintain good dental health.

Q. What are some other benefits of using mouthwash?

Besides freshening your breath and eliminating bacteria, depending on the formulation, mouthwash can also help prevent cavities, reduce plaque build-up, and soothe oral tissues. It’s essential to choose a mouthwash that targets your specific needs and use it correctly for maximum benefits.

Q. How long should you keep mouthwash in your mouth?

Depending on the product’s instructions, the recommended time for swishing mouthwash in your mouth is 30 seconds to one minute. However, if you experience discomfort or burning sensations, it’s best to spit out the mouthwash and rinse your mouth with water.

Embracing Comfort in Oral Hygiene

Mouthwash is a valuable tool in our oral hygiene arsenal but shouldn’t cause discomfort or pain. By understanding the reasons behind the burning sensation and knowing how to choose the right product, you can ensure your mouth stays fresh and comfortable.

Remember, the goal of oral care is to maintain a healthy and happy smile. If your current mouthwash routine isn’t serving you well, don’t hesitate to explore alternatives. Your mouth—and your dentist—will thank you for it!
