Dentures are designed for each patient and are more comfortable than ever, but they have their own challenges. One that many wearers face is that the lower prosthetic can slip more often compared to the upper one. If this is happening to you, then you might be confused about why and what you can do about it. So, here’s a guide to get you back to a stable bite.

Why Lower Dentures Tend to Slip More Often

While dentures are custom for you, your mouth will need to adjust to them. If you had just gotten a new pair, then you’ll need to build the muscle control to keep your full smile in place. Slipping is fairly common for many people during this transition period.

In other cases, the underlying cause may be related to your jawbone shrinking. This happens with tooth loss as the bone density weakens. The ridges that once supported your lower prosthetic change shape, and the fit is affected.

Misalignment might be to blame for an unstable grin. For instance, if you have a partial, then the restoration may not fully line up with your natural teeth when you close your mouth. This can cause shifting throughout the day.

How You Can Keep Your Lower Denture Secure

Although your lower denture may move, there are ways you can get back a secure fit. These are a few solutions you can consider:

  • Practice Speaking: If a new pair is to blame, then you can facilitate your transition by reading aloud and pronouncing tricky words. This can get you used to how they feel in your mouth.
  • Reline Your Dentures: Your dentist can adjust your prosthetic by adding material to the base. This can contour it against your gums; that way, they sit right.
  • Consider Dental Implants: This tooth replacement uses posts that are placed and fused to your jaw. They act like tooth roots and attach to your restoration. So, your full smile stays secure, and it can preserve your jawbone.

In the end, your lower denture shifting can affect your everyday life, so you should find a solution that works for you. By trying the tips above, you can get back your stable bite and feel confident showing off your smile once again.
