Can Vegemite Help with Mouth Ulcers? Here’s What a Dentist Says
Mouth ulcers can be painful, frustrating, and often appear at the most inconvenient times. You may have come across home remedies online—including the idea that Vegemite could help treat them.
But does it actually work?
Vegemite is a popular Australian spread rich in B vitamins, which has led some people to believe it may help with mouth ulcers. However, according to Dr Andre, this is not a remedy he would personally recommend—and for good reason.
What Causes Mouth Ulcers?
Mouth ulcers can develop for several reasons, and understanding the cause is key to proper treatment.
Common causes include:
- Accidental trauma
Biting your cheek or lip can damage the soft tissue and trigger an ulcer. - Acidic foods and drinks
Frequent consumption of acidic beverages (like soft drinks or citrus juices) can irritate the lining of your mouth. - Nutritional deficiencies
Conditions such as anaemia or low levels of essential vitamins (especially B vitamins and iron) may increase your risk.
How to Treat Mouth Ulcers
Most mouth ulcers heal on their own, but there are ways to manage discomfort and support healing.
Recommended treatments include:
- Warm salt water rinses
A simple and effective way to reduce bacteria and soothe the area. - Keeping the area clean
Good oral hygiene helps prevent further irritation or infection. - Topical treatments
Over-the-counter creams or gels can reduce pain and inflammation. - Laser treatment
In some cases, dentists can use laser therapy to speed up healing and reduce discomfort.
How Long Do Mouth Ulcers Last?
In most cases, mouth ulcers last between 1 to 7 days and heal without complications.
However, you should see a dentist if:
- The ulcer lasts more than 2 weeks
- The pain is severe or worsening
- Ulcers keep coming back frequently
Treatment may vary depending on the underlying cause, so a proper diagnosis is important.
So… Should You Put Vegemite on a Mouth Ulcer?
While Vegemite contains beneficial nutrients, applying it directly to an ulcer is not a proven or recommended treatment.
Dr Andre’s take?
He wouldn’t try it himself—and suspects it would likely cause more discomfort than relief.
