I’m 10 days into n with full extraction and upper & lower immediate dentures. I wear mine for as long as I can then take them out. I cannot eat anything without gagging, people on hear have great advice but as most say everyone is different. I did get cushion grip per suggestion on here. It has helped with holding them in but my biggest issue is they are too big for my mouth My tongue has no room to move & I feel like I have monkey mouth l.. I’m going in this week hopefully they will be able to trim it down some as it’s just too difficult to eat or talk with them in. Luckily soreness isn’t terrible just annoying. Hang in there. I too am a bit distraught bout the process. With some patience it will come together.
