Limitations

  • Over time, the remaining natural teeth in the mouth move position, especially if they are pushed by the retainers containing the dentures. Also, the bone that supports them changes shape (in the same way as the face and body), meaning the prosthesis will gradually become deformed and may cause discomfort or ulcerations and will need to be adapted by the dentist, and after a certain time, replaced by a new one.
  • Also, the metallic (and acrylic elements) used in removable dentures can snap due to what is called elastic fatigue (in the same way as a wire if it is bent back and forth too many times). These fractures must be repaired immediately in order to avoid additional problems caused by broken components.
  • Also, the fact that they are not fixed in place means that they wobble slightly, especially with certain types of foods that break down into small, hard particles (such as biscuits or nuts), which can become stuck under the dentures.
  • These movements can be quite noticeable in full dentures, especially on the lower jaw, and even more so when the edges of the gums have retracted significantly.
