Just had my bottom teeth pulled with stitches. Got my temporary dentures put in immediately. Very painful & a really bad fit. Went back to the dentist 2 wks later & he did some adjustments on them which helped a lot. After leaving there I stopped at Walmart & purchased a product called ReLine It. It’s a powder & liquid that you mix, spread it into the denture then put it bac mouth & bite down for 6 mins. Now my temporary denture fits my gums perfectly! You get 2 applications in the box & it was under $6 it peels out pretty easily to replace in a couple of weeks as my swelling goes down. They sell DenSure Fit on line but it’s $60 & they send it to you every month. A membership thing I couldn’t afford.
