I had much trouble with temporary dentures throughout much of 2024. Mainly gagging despite constant trimming by the staff throughout the spring. I did finally go in and get the permanent ones in Oct. or Nov. But I still struggle to keep the bottom ones to stay in without gagging within a short time. I know that I can have them fix them more; but I'm really frustrated with the whole thing and regret having my teeth pulled.
If so, you need to be seen by an actual dentist as they obviously don't know what they're doing. You need to see the dentist before the staff trims them beyond fixing.
If you're not in a facility, then go to a different dentist.
There's no reason you should be suffering with that problem.
It sounds to me either of 2 things is happening here. Either you have a VERY ramped up gag reflex, or, the dentures are too big for your mouth. There are a LOT of very bad dentists and labs out there, so the possibility the appliances are too big for your mouth and nobody realizes it are very good. I wear a full upper denture myself. If you could see the second set my dentist had made for me, you'd laugh as hard as I did. It looked like horse teeth. And he KNEW me. I'd asked for larger teeth bc the first set were too small, and these were huge. Ridiculous. I left his office and rejected the denture. I went instead to a denture place that ONLY made dentures and had a lab on site. So any adjustments were made on the spot. Night and day difference. The first try the denture was perfect. It required no adjustments at all. It was 50% lighter weight than the one I had been wearing. Just an incredibly well made appliance vs a piece of junk. But I didn't realize the original one was bad until I had a better one. Much like a first husband.....🤣
Don't give up. Find out from a place that makes dentures and has an on site lab if these fit right? If they are too heavy? If they are female teeth (mine were male!), etc. Let a pro tell you why you're having such issues.
If worse comes to worse and it's your gag issue that can't be fixed, just wear the uppers. Lower dentures are notoriously difficult in general. You can still chew w/o the lowers. If they move around too much and that's an issue, there's a product called Cushion Grip you can get at Wal Mart or Amazon that's a reliner material. You press it into the crevice of the denture and it WILL NOT come out for a few days. Its like cement 😂 It can also be used with an upper denture, but not until it gets loose. Super Poligrip Power Max is the best. A little bit keeps that puppy in place for 12 hrs.
Wishing you the best of luck with a difficult situation.
