Had a bit of a toothache the other day and smoked a Djarum Black Clove cigarette and the ache went away. Just sorta held the smoke in my mouth etc.For a toothache, you may use a leaf of Clove.
Sniffing warm salt water thru the nose helps with nasal and throat issues. I do it just to keep thing cleared out and in good working order.
Toothpaste makes a fine polishing paste. (Not gel types)
