DIY Mouthwash for Canker Sores with Essential Oils


DIY Mouthwash for Canker Sores with Essential Oils

Canker sores, also known as aphthous ulcers, are small, painful sores that develop inside the mouth. They can make eating, drinking, and even talking uncomfortable. While they typically heal on their own within one to two weeks, finding relief from the discomfort they cause is a priority for many people. One effective and natural remedy is a DIY mouthwash made with essential oils and sea salt. This easy-to-make mouthwash not only helps in soothing the pain but also promotes faster healing.



  • 1 tablespoon sea salt
  • 2 drops tea tree oil essential oil
  • 2 cups of warm water


Benefits of the Ingredients:

Sea Salt: Sea salt is known for its healing properties. It helps to reduce inflammation, kill bacteria, and promote the healing of the mucous membranes in the mouth. When used as a mouthwash, it can provide immediate relief from the pain and discomfort caused by canker sores.

Tea Tree Oil: Tea tree oil has potent antiseptic, antibacterial, and anti-inflammatory properties. These properties make it an excellent choice for treating canker sores, as it helps to reduce the risk of infection and speed up the healing process.

Warm Water: Warm water helps to dissolve the sea salt and disperse the tea tree oil evenly. It also has a soothing effect on the inflamed tissues in the mouth, providing immediate comfort.


How to Make and Use the Mouthwash:

  1. Mix the Ingredients:

    • Start by dissolving 1 tablespoon of sea salt in 2 cups of warm water. Stir well until the salt is completely dissolved.
    • Add 2 drops of tea tree oil to the saltwater solution. Tea tree oil is potent, so make sure to use it sparingly. Mix thoroughly to ensure the oil is evenly distributed.
  2. Rinse Your Mouth:

    • Take a mouthful of the prepared mouthwash and swish it around your mouth for about 30 seconds. Make sure to focus on the areas where the canker sores are located.
    • Spit out the mouthwash after rinsing. Do not swallow it, as tea tree oil is not safe for ingestion in large quantities.
  3. Repeat as Needed:

    • Use this mouthwash 2-3 times a day until your canker sores heal. It’s especially beneficial to use it after meals and before bedtime.


Additional Tips:

  • Maintain Oral Hygiene: Regular brushing and flossing can help prevent the occurrence of canker sores and promote overall oral health.
  • Avoid Irritants: Stay away from spicy, acidic, or rough-textured foods that can aggravate canker sores.
  • Stay Hydrated: Drinking plenty of water helps to keep your mouth moist and promotes healing.


Safety Precautions:

  • Essential Oil Sensitivity: Some people may be sensitive to tea tree oil. If you experience any adverse reactions such as a burning sensation, discontinue use and rinse your mouth with plain water.
  • Consult a Professional: If your canker sores persist for more than two weeks, or if they are unusually large or painful, consult a healthcare professional for further evaluation and treatment.

Using a natural mouthwash made with essential oils and sea salt is a simple and effective way to manage the pain and promote the healing of canker sores. With just a few ingredients and a couple of minutes, you can create a soothing rinse that provides relief and supports your oral health naturally.
