Use this to help "Burning Mouth"
Flavor Name: Fresh Mint, Size: 3 Ounce (Pack of 1)
I had laser surgery on my tongue a few years ago and developed burning mouth. Changing to this toothpaste has helped. (It won't completely relieve burning mouth, just helps) It doesn't have detergents and bleach that regular toothpaste does that irritate lasered mouth areas.

Bigger than I expected
Flavor Name: Fresh Mint, Size: 3 Ounce (Pack of 6)
I bought these to keep a toothbrush and toothpaste in my purse for after meals. I guess I didn't try to estimate size based on weight and thought they would be smaller. These are really just short tubes of normal size toothpaste - too big to carry in my purse.

the travel size
Flavor Name: Fresh Mint, Size: 3 Ounce (Pack of 1)
I love Tom's toothpaste as it is a toothpaste with non GMO products and it was great to find it in travel (TSA compliant) available.
