allergy

Hello, Your question is not unusual, but isn't that common either, but it is a serious situation that has to be corrected, and can not be corrected by adjusting the denture, from what you mentioned, you had an allergic reaction to both of your new upper dentures, When the dentures are been made in the dental lab, there are certain specific technical procedures that have to be followed and can not be short cut. One of these is the length of time the acrylic material used to make the final denture is processed to cure the ingredients used. If this allotted time is reduced or the mixture of the two ingredients is wrong, the material does not cure properly, and you are left with this uncured, liquid acrylic inside the denture, which can cause the reactions you mentioned. Aside from that you may be allergic to the acrylic itself, which in that case a non-allergic acrylic has to be used. Either way, you need the denture remade properly, as well as the lower partial made properly. The largest reaction to these reaction chemical issues is on the upper denture , because of it's location and closeness to tissue. I suggest you return to your dental practitioner and discuss this with him or her, and have them remake the denture and have the lab procedures followed closely to make sure either the acrylic material is cured properly and/or a different material is used all together. very best regards,
