The ONLY Thing That Seems to Help
“I’ve had canker sores my whole life. NOTHING numbs the pain and lasts as long as Kank-a!”
Yes don’t think twice get this stuff
My husband and I both had toothaches bad ones at different times and this stuff really helps. The brush really helped deliver the medicine exactly where needed.
Works Pretty Good
My dentures had to be re-lined because of cancer, and I constantly get gum sores. Tried a whole bunch of products, then came across this. I was surprised and happy that this makes such a difference.
Immediate Pain Relief. Numbs Pain Fast.
“I spent $6.99 instead of $14 on another brand, and I’m so happy! This is probably the best purchase I made!”
Instant Pain Relief
I applied this medication & had instant relief. Pleasant taste. No odor.
