Spicy foods
Spicy foods can aggravate mouth ulcers by causing irritation and inflammation, especially if you have open sores. It is best to stay away from red chili, spicy sauces and dishes with many spices.
Citrus foods
Citrus fruits such as oranges, lemons and grapefruits contain citric acid. These fruits can cause serious irritation to ulcers and blisters in your mouth.
Carbonated drinks
Carbonated drinks are not for people with canker sores. Carbonated drinks contain acids that can irritate the soft tissues in the mouth and lead to swelling and ulcers. The high sugar content in these drinks can promote the growth of bacteria and lead to infections.
Coffee contains caffeine
Coffee with a high salicylate content can irritate your gums and tongue. If you want to drink coffee with canker sores, you should reconsider your choice and try to limit your coffee intake.
Alcohol
Alcohol dries the mouth and can also damage the protective covering in the mouth. This leads to a delay in the healing process of canker sores, causing pain and inflammation. Therefore, avoiding alcohol is the best choice to heal canker sores faster.
Food is too hot and too cold
Foods that are too hot or too cold are not suitable for canker sores because they are very sensitive. It is best to eat foods at a mild, moderate temperature to avoid affecting the area with canker sores.
