Loose Lower Denture? 5 Fixes, From Simplest to Most Secure

This article is general information. Your own care plan depends on an assessment of your mouth.

A loose lower denture is one of the most common complaints we hear. It lifts when you talk, shifts when you chew and sends you reaching for adhesive. Upper dentures hold with suction against the roof of your mouth, but a lower denture sits on a narrow ridge with your tongue moving around it, so it is much harder to keep in place.

The good news is there is more than one fix. Here are five options, from the simplest to the most secure. We are the team at Kasper Denture Clinic in Vernon, Kelowna and Lake Country.

Fix 1: Denture adhesive

Adhesive can help a slightly loose denture feel more secure for the day. It is a short-term help, not a fix. If you need more and more of it, the denture no longer fits your gums and the real problem is still there.

Fix 2: A reline

Your gums and jaw shrink over time, so a gap opens up under the denture. A denture reline fills that gap by refitting the base to your mouth as it is today. For a lower denture that used to fit well, this is often all it needs.

Fix 3: A new, better-fitting denture

If your denture is old, the teeth are worn or it was never a great fit, a reline will not fix it. A new denture made with careful impressions and a properly set bite can make a big difference on its own.

Fix 4: A lower suction denture

A lower suction denture is designed to form a seal around its edges, using the technique taught by Dr. Jiro Abe of Japan. Special impressions are taken with your mouth relaxed and closed, and the edges are shaped so your soft tissue seals around them. Many patients find it holds without adhesive, with no surgery needed.

Not every mouth can form a strong seal, so it depends on the shape of your lower ridge and the tissue around it. That is checked at a consultation.

Fix 5: Snap-in implant dentures

For the most secure hold, snap-in implant dentures clip onto two or more implants placed in your jaw. They do not slip, and many people find they can eat foods they had given up on. Implants are placed by your dentist or an oral surgeon, and the denture is made to attach to them.

Which fix is right for you?

• Slightly loose and fairly new? Start with a reline.
• Old or worn? A new denture is usually the better spend.
• Always floated, even when new? Look at a lower suction denture.
• Want the most secure option and open to surgery? Consider implant dentures.

The right answer depends on your gums, your bone and what matters most to you. Jason will check all of that and walk you through the options side by side.

Why lower dentures loosen more than uppers

An upper denture covers the whole roof of your mouth, which gives it a large surface to create suction. A lower denture only has a horseshoe-shaped ridge of gum to rest on, and your tongue, cheeks and lips are moving around it every time you talk or eat.

After lower teeth are removed, that ridge also tends to shrink faster than the upper one. Over a few years there is simply less to hold on to, which is why a lower denture that fit well at first can start to float.

Habits that make a loose lower denture worse

• Using more and more adhesive instead of getting the fit checked
• Wearing the denture overnight, which keeps pressure on the ridge
• Chewing mostly on one side
• Putting off a reline until the denture cracks

Questions about loose lower dentures

Can a loose lower denture be fixed without surgery? Often, yes. A reline, a new denture or a lower suction denture can all help without surgery. Implants are the option that needs surgery.

How many implants does a snap-in lower denture need? Usually two to four. Your surgeon and denturist will talk through what makes sense for your jaw.

Will a suction denture work for me? It depends on the shape of your lower ridge and the tissue around it. That is checked at a free consultation.
