Hello,
I am asking for advice. My 73-year-old wife received an upper denture six months ago. It is retained on three attachments in tooth roots. One of these attachments has failed for the second time, but that is not the biggest problem. The problem is that her tongue and lips frequently swell, which of course causes pain. Despite rinsing the teeth and denture several times a day, especially during the night-time rinse (at least once per night), the rinsing liquid becomes dark in colour. We understand that one has to get used to a denture. However, the pain is not subsiding, and the burning sensation in the mouth and on the palate is often unbearable, so she has to remove and wash the denture. During rinsing in the daytime the liquid is not dark, perhaps because of the frequent rinsing.
Could this be because the body is rejecting the foreign body (the denture)? Could there be another cause? Where should we turn to check a suspicion of poor tolerance of a foreign body in the mouth? Thank you in advance for your answer. Kind regards, Janez from Maribor.
