No.
Cheap salt and food with normal salt/cheap salt give me blisters in my mouth. Now I always buy the expensive salt and that is OK and does not cause any blisters.
For the majority of normal peoples - no.
Yes, I had a very bad cavity that hurt like hell, but when I rinsed my mouth with the salt, it felt a little better.
Get a spoon pour a little salt on it and pour right on the blister it will sting a little and the salt will dissolve right on but it heals supper fast
Make before an experiment; but avoid excess salt, you don't need salt water in the mouth.
There might a special ointment you can buy at a drugstore. Otherwise just avoid very salty foods for two-three days. That's what I do after I eat a whole bag of salt & vinegar chips. More info: Try rinsing your mouth with a warm salt water rinse. Mix about 1/2 teaspoon water in a half glass of warm water and rinse, then spit it out. Salt has natural antibacterial properties, and will help dry up the blisters.
Salt create a sensation of saltiness on the tongue.
You can purchase over the counter medication at your local drug store, but I always find that salt and warm water helps with the discomfort of a sore mouth and tongue. Just swish warm water and salt in your mouth. Swish as though it were mouth wash. Gargle, too. Be generous when adding the salt to water and do this several times. Your mouth will feel so much better and you can continue to do this throughout the day if needed. An alternative method to soothing the pain of these annoying blisters is to rub an ice cube on them until they are numb. As they are healing you should stay away from salty or acidic foods. The most common reason one might contract these blisters is from eating too many sweets. DO NOT scratch the blisters with your teeth. This slows down the healing process. You may get these blisters from not drinking enough water. So drink lots of icy cold water and the blisters should disappear in no time! I have never seen a reply like mine on anyone's site, but I have used this remedy for years with tremenous success. I treat these tiny blisters like a hang nail and simply snip them off with nail clippers. I know this sounds just dreadful, but instead of having lingering misery for days while the blister heals, there is only a small pinch and the pain is gone instantly. The best clippers are big 6-inch double-handled toe nail clippers with the super sharp blades. There is hardly any blood, either, and the spot heals immediately.
You should keep salt on a mouth ulcer for about 5 minutes.
Only if you're testing for salt.
Yes, it is possible.
It is safe to put water in your mouth, but salt can be harmful if consumed in large quantities. Small amounts of salt in your mouth can help with sore throat or oral health, but be careful not to ingest too much.
