Whats the diff?

Both say zinc free, 12 hour hold, so what's the difference? The Polygrip DOES have zinc (.02%) which in folks, like myself that's allergic... That's .02% too much. It caused me to have neurological symptoms... In fact I thought I was about to have another stroke until someone mentioned that there is a small amount in there so maybe stop using it and see what happens.

The Secure has NEVER had zinc....not in trace amounts or otherwise. Yes it does hold  12 hours....at least. Haha at 20 hours it had just as strong of a grip as it had on minute one. Removing it was a bit of a challenge.... There was no goo. There was gummy but no goo. That was after you felt the teeth 'lift' ...once it does that, they come out in about a minute with a good rinse, then brush and peel away the gum and start over.

The cost is comparable...the product is nature based...even with cost for delivery. I live with many allergies on a daily...to me, its totally worth the investment. Also since the teeth stay firmly attached thru hot soup, salad, cereal, etc. Foods I've really missed....chips! Secure allowed me to eat an entire bag......nothing gets under. In fact...the only thing that stopped me from eating too many.....I was full....and very aware of how many calories I was consuming. Great stuff.

Find the mid-line?

Say what? If you don't know all them dental terms and you tell the dentist that your dentures are off....you don't want to hear find the mid-line....you want to know what to do...in plain old everyday English!

I fussed that my teeth felt uneven, especially after the gums tightened up and shrunk...I was told 'look for the mid line' and line them up. Ya ok. Well after eating, I clean my teeth and put them back in if it isn't bedtime. Well today, after a very good pb and j...I had to take more time cleaning them...and that's when I seen it....they ARE uneven...or specifically...off center. But knowing that, I can adjust the way I put them in. Tried it...even with the "midline" method....lining them up the way they fit in mouth works a lot better than mid-line placement at the freenum thing. It took a little practice without the adhesive, but now I can do it without thinking about it.
