I have been using Sea Bond for over 20 years. They are easy to cut to size, and easy to apply and remove. Dentists have told me the seals have kept me from losing valuable bone, because they keep my dentures from moving when I chew. I just wish they were manufactured with a stable consistency, because each package will have wafers with a different thickness and color; some are wafer thin and lightly pink; others are thick and dark pink. I can only use the thin, light pink ones. Very rarely do they last all day; I usually have to change the lower after each meal because food, especially sweets, tend to coat the wafer and make it uncomfortable; they are, however, MUCH better than paste or cream adhesives! I have to comment about the mint-flavored wafers: how can anyone want their food and drinks to taste like mint? Mint-flavored pizza? It's disgusting!
