What kind of denture adhesive is useful for sensitive gums?

No Denture Sores: Sore gums under a denture is a sign that dentures are not fitting properly. The denture moves & irritates the mucous membranes under the denture. You should see a prosthodontist with extra training in this area. They will evaluate the denture's fit to the gums & how they meet when biting/chewing & how tall the teeth are. All these contribute to denture fit. Adhesive can't fix ill-fitting dentures.

Try out many: There are many types of denture adhesives available. The only way is trail. Try the pastes, powders, pads. Different brands until you find which is the most comfortable. With that being said if a denture is made probably you shouldn't need to use adhesive.

I recommended water : I recommended water proof secure and this product us zinc free. Taste free and it doesn't hurt gums at removable another that works fine is super poligrip and it holds long time with some peppermint flavor

None: Gums are typically sensitive because they are not stable in your mouth and the rubbing causes sensitivity to the gums. If the denture is stable and secure the gums will not be sore.
