Here are some symptoms that may indicate you may have a loose denture:
Your implant-supported dentures feel loose when you bite or chew.
You can see that they are moving when you talk or smile.
You notice a gap between your dentures and gums.
They feel uncomfortable and loose.
When these happen, you should consult with your dentist right away. They will be able to check if your dentures are still securely in place or need to be adjusted.
