Hi again Pav
Me and my mouth are very well. Thank you for asking. I'm sorry to hear about the complications you're experiencing. New dentures are difficult enough all by themselves never mind having an infection as well. I hope you're not "resistant" to antibiotics. The sooner they start to work the sooner the swelling will go down and the sooner the swelling goes down..... well, you get the idea. I hope you have the root removed despite having to traumatize your gums again. The last thing you want is the possibility of recurring infections. If you're like many new denture wearers, that was one of the symptoms of bad teeth that dentures were supposed to address!
You've had your dentures for a month now. Most new denture wearers have a soft reline done in the first 2 to 4 weeks after extractions because the gums resorb (shrink) the most in the first month. Given the situation with your lower gum I wouldn't be rushing out to have a soft reline done now but you should consider it when your gum has healed sufficiently after removing the "wrap around" root. Removing the root will also change the shape of your lower gum in that area so the denture will need adjustment. A soft reline should do that. So see your dentist about the fit once the gums have healed a bit after getting the root removed.
The easiest way to tell if you need a soft reline is to check for movement in the dentures. Clench down on the rear teeth with moderate pressure. Both the upper and lower denture should press firmly together with little or no movement and with even pressure on the gums. If either the upper or lower denture tips from front to back or side to side that would indicate a problem with the fit. I had a soft reline done near the 1st, 2nd, and 3rd month after extractions. Then I went for 3 months without another soft reline until the hard reline which I had done at 6 months. Tomorrow (today for you) it will be 10 months since my extractions. Getting dentures was one of the wiser things I've done with my life in recent history.
It's important that your dentures fit as well as possible in the first few months but because your gums are changing quickly and constantly during that time it's not easy to maintain a really good fit for long. Learning to eat with with well fitting dentures is difficult enough. You don't need poorly fitting dentures to make matters more difficult than they need to be. You might even want to consider getting a soft reline if only to put to rest any questions you have about how your dentures should fit and feel.
I hope your infection goes away quickly and that they take out that root. With a little bit of luck you'll be able to start eating a little more than "mushy stuff" soon afterwards. Good luck!
