Let me teach you some relatively simple methods^^;;

Watermelon: Take half of the watermelon, scoop out the pulp, squeeze out the juice, and hold the juice in your mouth, about Swallow it after 2 to 3 minutes, then take the fresh melon juice and repeat several times.

Vitamin C: Crush 1~2 vitamin C tablets, apply on the ulcer surface, close your mouth for a moment, 2 times a day.

Tomatoes: Hold tomato juice in your mouth for several minutes at a time, several times a day.

95% ethanol: Dip a cotton swab into 95% ethanol, gently press the oral ulcer point, and gently turn the cotton swab to remove the corrupt tissue on the ulcer surface, 2 to 3 times a day, 20 to 30 seconds each time . To treat oral ulcers, most of them heal within 2-3 days

Honey therapy: Rinse your mouth clean, then use a sterilized cotton swab to apply honey to the ulcer surface. Do not eat or drink after applying. After about 15 minutes, you can swallow the honey with your saliva, and then continue to apply it. You can apply it several times a day.

Apple therapy: Cut an apple (a pear is also acceptable) into slices and place it in a container. Add cold water (covering the apple or pear to be cooked) and heat it until it boils. Wait for it to cool down slightly before adding it to the wine. Hold it in your mouth for a while and then eat it. Use it for a few days to cure the disease.

The above are relatively simple, you should pay more attention to oral problems ^^;;
