Over time, false teeth begin to fit poorly due to changes caused by bone and gum loss. As this happens, it can cause your dentures to slip while you talk. As a result, you’ll probably find yourself having to speak slowly or having to bite down to put your dentures back in place. A new denture or a denture reline can be done if this is becoming bothersome. That is why even though you may not have your natural teeth it is still important to routinely visit the office.
