Thanks to the adhesive powers of zinc, this powder will hold your upper tight most of the day. It takes patience and creativity and knowing your own habits to make it work correctly. I’ve found applying a little more than a light layer to a still-damp plate following cleaning will hold dependably all day. If you’re new to prosthetics, becoming self-aware is the key to success, whether it be teeth or a leg. Experimenting is the key and making good notes in the beginning will help you track and improve your success. I find for myself, using the above mentioned layer and rinsing my mouth with water before application works reliably for myself, you may be different. Press the device in place and lightly massage while pressing for about the count of 20. Getting a good initial seal is the key to success. If it’s not holding well, swish about a tablespoon of water in your mouth, spit, and try pressing again. There is a learning curve involved in using these appliances, so please be patient with yourself. As I don’t have a full lower appliance, I can only imagine this would work well. For a partial appliance, I highly recommend the PolyGrip Power Max Hold and Seal, which is NOT a powder. The trick to success with both types of appliances is trying and especially making notes of your successes. After a couple of years of these, I literally eat and chew better than the teeth I was born with, not good DNA in my lineage for them, sadly. Make note of your activities: smiling, laughing, problematic foods (those with seeds are a universal problem for all.) Keep your adhesives handy throughout your day in the event you need to make an adjustment or if your day is running longer than you intended. Cleanup is simple in your sink (always apply over the sink) I keep a small container of Barkeepers Friend handy in case the powder doesn’t rinse away easily. Remember, it is meant to bond with light moisture. To remove from your appliance, I keep a small container of Dawn next to my sink, along with a stiff denture brush, to help remove any excess before soaking. In my travel bag, I keep a tube of Arm and Hammer Baking Soda Toothpaste, which easily removes any residue from your appliance or mouth. Arming yourself with knowledge and paying meticulous attention to what works for you and when will enable you to eat pretty much anything you choose. If I know I’m having a cookout with ribs and corn on the cob, for instance, I’ll use the PolyGrip product liberally on both upper and lower and pay attention to firmly holding in place for maximum adhesion, I can not only eat what I choose, but keep food particles from getting past the seal and making eating unpleasant. If this is your first time with an oral prosthetic, the powder will help give you your confidence back. Remember NOT to touch the tip of the powder “nozzle, if you will) to the denture itself and keep the cap away and dry (I use a napkin or tissue to set it on). If the bottle does become clogged, don’t throw it away, use a large pin to insert into the applicator hole to make it bigger. You will have probably more than you need coming out faster, so use sparingly and thank yourself for not losing all your money. If you’re having denture problems, the best bet is to get the lightest denture material you can afford, and never opt for a reline should they lose their fit, particularly on the upper as they become too heavy and you’ll need an enormous amount of any adhesive to keep them in place. These items will not last a lifetime as your gums and bone structure will change as you age. Set aside a fund so you can replace when needed. My first set lasted close to ten for me, but they will wear down from eating as well. As you can tell, this review was aimed towards the new denture wearer, in hopes that sharing a bit of my experience may help others with a smoother transition. Do everything you can to boost your confidence while you adjust to these, be nice to yourself and your miracle will happen when you find YOUR WAY to manage your oral hygiene. I truly only think of them once or so a day while cleaning.
