The teeth to be retained are typically given root canal treatment and then substantially reshaped. These reshaped teeth are often covered with metal caps to prevent erosion of the remaining tooth structure. The advantage to the over denture is that the denture itself seems to be more stable when in use. They will have to be periodically relined. Over time, as jaw bone recedes, the dentures may need to be remade as they have become excessively loose.
Many people find chewing more difficult.
Taste and enjoyment may be affected because the denture may cover taste buds on the roof of the mouth. Dentures may become painful as a slight shifting of position can create sore spots on the gums or extreme bone recession can expose portions major nerves. Some people find that dentures, no matter how well-crafted, cause them to gag. As most of these potential problems usually occur later in life, they can challenge the ability to maintain good health, when eating a proper healthful diet is essential. If disease or injury are not too great or if cost is not the most significant factor, there are better alternatives to dentures.
