Canker sores may be tiny, but anyone who has had one knows how painful they can be. Eating becomes annoying, talking feels uncomfortable, and even brushing your teeth can sting. Over the years, the author has tried dozens of natural remedies some worked beautifully, some didn’t do much at all. This guide focuses on the 8 natural remedies that consistently provided relief, along with gentle, honest advice based on experience, not just theory.

While everyone’s body reacts differently, these remedies are safe, simple, and backed by both anecdotal experience and traditional healing practices. A couple of Amazon products are included both tried personally and chosen because they genuinely worked, not just because they’re popular.

Let’s get into the remedies that truly make a difference.

1. Honey (Raw, Pure Honey Works Best)

Honey is one of the oldest natural remedies for mouth sores, and for the author, it’s still one of the most reliable. Raw honey has natural antibacterial and anti-inflammatory properties that help soothe the sting and shorten healing time.

To use it, a tiny dab is applied directly to the canker sore 3–4 times per day. The stinging reduces almost instantly, and within 24 hours there is a noticeable improvement. The author found that regular supermarket honey doesn’t work nearly as well—raw, unprocessed honey is the key.

One unexpected benefit? If a canker sore makes it painful to eat, honey acts like a soothing shield over the spot for several minutes.

Perfect for:
• Lip canker sores
• Tongue sores
• Gum sores
• Kids (gentle, safe, effective)

2. Baking Soda Rinse (Classic but Powerful)

A simple baking soda rinse may not sound impressive, but anyone who has tried it knows how effective it is at calming irritation.

The author has used this remedy for years, especially when a canker sore appears in a sensitive spot like under the tongue or along the gumline. Baking soda helps neutralize acids in the mouth, reduce inflammation, and speed healing.

How to use it:

• Mix 1 tsp baking soda in half a cup of warm water
• Swish for 20–30 seconds
• Repeat 2–3 times daily

It does NOT taste good—but it absolutely helps.

Perfect for:
• Large or deep sores
• Multiple sores at once
• Pain triggered by acidic foods

3. Milk of Magnesia (Surprising but Works)

Milk of magnesia is traditionally used for digestive relief, yet it works wonders for canker sores too. It creates a protective coating that shields the sore from irritation and helps reduce inflammation.

This remedy is especially helpful when the sore burns every time something touches it—food, toothpaste, even saliva.

How to use it:

• Dip a cotton swab in milk of magnesia
• Apply directly on the sore 3–4 times per day

In the author’s experience, this remedy works well in combination with baking soda rinses, dramatically reducing healing time.

4. Salt Water Rinse (Harsh but Effective)

Nobody likes the sting of salt water—but this classic remedy works. Salt is naturally antibacterial and helps draw out moisture that can worsen inflammation.

Whenever a canker sore feels extremely swollen or enlarged, this rinse helps flatten it faster.

How to use it:

• Add 1 tsp salt to a cup of warm water
• Rinse for 15–20 seconds
• Repeat twice daily

It hurts for a moment, but the relief that follows is worth it.

5. Aloe Vera Gel (Soothing & Cooling)

Aloe vera is best known for skin burns, but its benefits extend to mouth sores as well. The cooling sensation alone provides instant comfort, especially if the sore is on the tongue or inside the cheek.

The author once tried aloe vera gel after almost everything else failed—and within hours, the burning sensation reduced dramatically.

Make sure to use food-grade aloe vera gel, not the skincare version.

How to use it:

• Apply a dab to the canker sore 2–3 times per day

It’s gentle, safe, and particularly useful for children or those with very sensitive mouths.

6. Essential Oils (Clove or Tea Tree)

Essential oils must always be used carefully, but when diluted properly, they can significantly reduce pain and inflammation.

The author personally found clove oil to be the most effective. It contains eugenol, a natural compound often used in dental treatments for pain relief.

How to use clove oil safely:

• Mix 1 drop clove oil in 1 tsp coconut oil
• Apply gently with a cotton swab
• Do NOT use it undiluted—it is too strong

Tea tree oil is another option, known for its antibacterial properties, but it must always be diluted and never swallowed. For adults only.

7. Ice Cubes or Cold Compress

This remedy is simple but incredibly relieving when the pain feels sharp or throbbing.

Placing a small ice cube against the canker sore numbs the area temporarily, reducing swelling and irritation. The author uses this especially when a canker sore appears after eating too many spicy or citrusy foods.

Perfect for:
• Severe burning pain
• Throat or inner-mouth sores
• Moments when fast relief is needed

It doesn’t speed up healing, but it makes the discomfort easier to tolerate.

8. Vitamin B12 & Zinc Boost (Internal Support)

One of the most surprising discoveries for the author was how often canker sores were linked to mild deficiencies—especially vitamin B12 and zinc.

Whenever stress, poor diet, or irregular eating habits appear, canker sores become more frequent. A simple daily supplement reduced their occurrence significantly.

While supplements are not a “quick fix,” they are incredibly helpful for preventing repeated breakouts.

Honest Amazon Recommendations (Only 2 Products That Truly Help)
