Pros: Immediate relief and easy to use
Cons: Pretty strong taste and odor.
Incredible how this med works. Its active ingredient is Eugenol 85%. Other higher priced OTC's can't compare to the effectiveness of Red Cross's Toothache. Numbs the pain instantly and for hours! Does burn and you must spit for 5 - 10 minutes. You will obtain relief and you will sleep! Keep extra bottles.- nothing like it on the market. Keep extra bottles - you can't go wrong and you will be grateful you did.
