Probably the only difference is price. Salt is salt no matter where it comes from. The only thing that alters it is what they put in after they get it such as iodine. Just normal table salt should do the trick if you're using it as a mouthwash.
I use both. I like the taste of mouthwash. But if I have a problem such as an infection I will use warm salt water. It works great at canker sores.
Comments: Is there any need to rinse with regular water after the salt water rinse? Salt water seems corrosive and that would seem to be bad for teeth.
That's a good point. There is so much we take into our mouth that is corrosive to our teeth and terrible for our gums that I can only see a little mixture of warm salt water as a mouth wash doing more good than bad.
If you want to heal your gums the best is warm salt water. If you want to use mouth wash then try to use one without alcohol because that just damages your gums.
Title: Saline water and gums
Comments: I was not able to eat for many days. Every evening my gums would swell so I could not chew. Sleep, brushing teeth and sloshing warm water in the mouth, mouthwash helped but the problem persisted. I was on the verge of seeing a doctor and subject.myself to the rigmarole of designer anti-biotics and vitamin C.
Yesterday, I recalled my days of yoga and nasal flushing with saline water. I tried this flush in the.mouth. Relief! on the spot benefit. The pain drained away. I should have thought of the anti bacterial action of salt. I had stuck myself in the warm water remedy. Fool... Should have mixed it with warm water.
I will now do it all over my body in areas prone to infection.
Cheers to research on oneself. Down with doctors.
I used to work for a herbalist, who told me that you should always use salt water, to rinse, it apparently clears infections, preserves your gums and is supposed to be healthier all round. She did also say that you should use it to swill up your nostrils if used for a long time it hardens, and helps prevent coughs and colds... I haven't tried either pieces of advice, it just doesn't sound that great to me :)
