Back | Conditions of Gums | Denture Quality | Patient Skill | Dental Implants

It seems logical that if your gums are reasonable in size and condition that the dentures should have a stable fit. This is not always the case.

Many patients present with excellent gum size, but may have high muscle attachments, which, during certain mouth movements can easily dislodge a denture. Further complicating the problem are the tongue muscles, which are attached to the inside of the mandible (jaw), and are used for eating, talking and swallowing. These specific muscle attachments can easily "lift" a lower denture. Another factor to consider is the overall condition of the ridge (gum's). If the ridge is soft and unstable, the denture itself will be unstable. Two major causes of ridge deterioration are, over-wearing the same denture without any relining procedures for any time period of 3+ years, (more common on the lower ridge with full top and bottom dentures), and a complete upper denture opposing natural teeth where the occlusion (bite) is heavy on the front teeth, (upper ridge). The underlying bone is less dense in the front portion of the ridge than it is from the canine area to the back (retromolar area). This is why when you notice the back teeth (chewing teeth) on your dentures wearing flat it is an indication to replace the denture! Remember, it's easier to replace a denture than it is natural bone. Once the ridge breaks down, it's irreversible and can only be repaired through augmentation or dental implant therapy, which is a lot more expensive than replacing your denture every 5-8 years and keeping your ridge healthy and strong!!
