Is it obvious when someone has dentures or partials?
The answer to that question is sometimes you get what you pay for. When you choose to get cheap a cookie cutter denture product you are not only going to get poor aesthetic look but they may also be a poor fitting product.
Talk to your dentist about the options available. If you are wanting a more aesthetic looking denture think about spending a more if possible for the better choice. In most cases the dentist will be about to show you photos of each denture option.
