Foods That Cause Mouth Ulcers
Acidic fruits
![]()
Fruits that are acidic, or particularly citrusy, can cause your mouth to break out in ulcers. Pineapples, oranges, lemons, and limes are some examples of fruits with high acidity. Strawberries, in particular, tend to cause mouth irritation.
These fruits cause mouth tissue stress and can aggravate your gums. This is especially true if you already have a sensitive mouth. Any juices made with these fruits will also have the same effect.
Bananas, watermelon, and apples are good fruits to eat – you will avoid abrasion.
Nuts
As nutritious as nuts are, they are surprisingly bad for your teeth. Nuts such as walnuts, peanuts, cashews, and almonds are dangerous territory for your gnashers. It is the amino acid L-Arginine in these nuts that contributes to canker sores.
Salted nuts are especially bad, as the sodium dries your mouth out and cause the lining to become slightly inflamed.
Chocolate
Deal breaker! Chocolate, unfortunately, is a top food that causes mouth ulcers. This is mainly because of an alkaloid in chocolate called the obromide. The mouth is quite sensitive to this ingredient and it can lead to something similar to an allergic reaction. Some people who have this mild allergy will develop canker sores on their tongue and/or inner cheeks.
You don’t have to cut out chocolate completely, but if it causes you pain in your mouth, then consider cutting down on the cocoa.
Spicy Foods
Spicy foods can disrupt the lining inside your mouth, causing an ulcer. A bit like acidic fruits, spicy foods have high acidity and therefore are more likely to distress the skin.
You’ll want to avoid foods like curries, hot sauce, jalapenos, and spicy chips to save yourself from oral pain. Most of these are a double whammy, as they tend to have high salt content as well.

Hard Foods
This is quite a broad range of foods. Yet, it is foods classified as “hard” that are abrasive, sharp, and sore-forming:
- Raw vegetables
- Toast
- Potato chips
- Pretzels
It’s best to avoid these when you can if you’re prone to canker sores.
Alternatively, eat these in smaller sized mouthfuls. You could also combine the foods with something that takes the dry and hardness away. Applying extra butter to toast, and having raw vegetables or potato chips with dip may help your mouth cope better.
