Although they’re not found on the lips, they can be uncomfortable and very painful. People who suffer from recurring canker sores experience difficulties in drinking, eating, and even talking.

What are Mouth Ulcers

Mouth ulcers or aphthous ulcers are tiny open sores which develop in the mouth, on the tongue, the roof of the mouth, on the mucus membrane inside the lips and cheeks, and in the grooves between gums and cheeks.

It starts as a burning and tingling sensation and a slight swelling of the site. The center of each ulcer is white, surrounded by an inflamed red border, which is tender to the touch. Ulcers can last from two days to three weeks; they heal spontaneously leaving no scar.

Mouth ulcers could be caused by a mild virus infection, but some research shows ulcers are brought on by a state of anxiety or emotional stress.

While having mouth ulcers, avoid acid or spicy foods that can cause more pain, hard foods, coffee, smoking and alcohol.

A cotton bud dipped in Tea Tree oil can be applied neat to the ulcer for immediate relief.

Sage belongs to the mint family, and it has cooling and healing properties that can bring relief and shorten the life of the canker sore. To make a sage rinse, boil four ounces of water, and toss in two teaspoons of dried sage.

Let it steep for 10 minutes, then let it cool. Take a swig, and swish it around in your mouth for a full minute. Spit it out, and rinse with cold water. Repeat every couple of hours.

Live-Culture Yogurt Snack

Live-culture yogurt is great for promoting good gut bacteria, but it may also help you rebalance the bacteria in your mouth to speed up the healing of a canker sore.

It’s worth a shot to consume a couple of servings of yogurt a day. Just make sure the yogurt you buy contains live cultures, since that’s what makes the magic happen.

Dietary & Lifestyle Tips for Mouth Ulcers

Aromatherapy is not a magic panacea, and should always be used in conjunction with other therapies and/or lifestyle changes. In addition to using the above mouthwash and spot treating, consider the following for keeping mouth ulcers at bay:

Notice what you eat and if certain foods are triggering your mouth ulcers

One common culprit is high-acid foods (tomato sauce, coffee, alcohol). Acidic fruits like oranges, pineapple, and grapefruit can also trigger canker sores. Salty foods might be the issue.

As a kid, I would frequently get a mouth ulcer after eating a ton of salty pretzels. And if you have specific food sensitivities or allergies, avoiding those foods may help prevent canker sores.

Reduce stress

This could be a bullet point related to just about any ailment—but it’s important! Emotional stress breeds physiological changes. Notice if you experience mouth ulcers during periods of increased stress. You may want to look into meditation and other stress-management practices.

Oral hygiene/mouth protection 

If you have braces, the irritation from them could be triggering your mouth ulcers. Ask your dentist about waxes to cover sharp edges. On the hygiene side, regular brushing (with a soft brush) and flossing can help keep your mouth clear of foods that might trigger an outbreak.

Also, avoid toothpastes and mouth rinses that contain sodium lauryl sulfate


1. How long do Canker Sores last?

People usually suffer two to six ulcers per episode which can last for weeks or months, depending on the category.

2. Are Canker Sores Similar to Cold Sores?

Unlike cold sores, caused by Herpes Simplex Virus 1, which are contagious, canker sores are benign and non-contagious. Canker sores always form inside the mouth, while cold sores tend to appear on or around the lips and occasionally affect the tongue, gums and the hard and soft palate.

Final Word

When having mouth ulcers, a natural resource is using oil-based products. Most the mouth ulcers disappear on their own in a week or two even without applying for any medicine or even doing any natural remedy.

But better to treat mouth ulcers while they are small and could easily be healed. In this way, you avoid big and painful mouth ulcers. There are also canker sores that do not heal.  Anyhow, if this happens to you, do not hesitate to consult your doctor or dentist immediately.
