How to Keep Dentures Snug: 8 Practical Tips

Updated October 2026

Few things are more stressful than dentures that slip while you are eating or talking. Some movement is normal, especially with a new lower denture, but there is a lot you can do to improve the fit. Here are our top tips from Mercer Island Dental.

1. Keep Your Dentures Moist

Acrylic dentures can warp if they dry out. When they are out of your mouth, keep them in water or a denture-soaking solution. Never soak them in hot water.

2. Clean Them Every Day

Brush all surfaces with a denture brush and a non-abrasive denture cleaner. Clean fitting surfaces seal better against your gums, and daily cleaning prevents bacteria and yeast buildup.

3. Use Adhesive the Right Way

A small amount of denture adhesive can improve the seal and keep food out from under the denture. Apply a few small dots or thin strips to a clean, dry denture. If you need more and more adhesive over time, that is a sign the fit has changed.

4. Train Your Tongue and Cheeks

Lower dentures do not get suction from the palate the way upper dentures do. Resting the tip of your tongue against the inside of your lower front teeth and letting your cheek muscles hold the denture in place gets easier with practice.

5. Eat Smart While You Adjust

Cut food into small pieces, chew on both sides at the same time, and start with softer foods. Very sticky or hard foods are more likely to dislodge dentures.

6. Give Your Gums a Break at Night

Removing dentures overnight keeps your gums healthier, which helps them support the denture better. Read more in our article on sleeping in dentures.

7. Get Regular Adjustments and Relines

After teeth are removed, the jawbone slowly shrinks, so a denture that fit perfectly at first will gradually loosen. Small adjustments are common in the first months, and a reline (reshaping the inside of the denture to fit your current gums) can restore a snug fit. Do not adjust or repair dentures yourself with home kits, which can damage them.

8. Ask About Implant-Retained Dentures

If loose dentures are a constant problem, dental implants can anchor them securely. Even two implants in the lower jaw can make a dramatic difference for a lower denture. Mini dental implants are another option for some patients, and a fixed All-on-4 bridge does not come out at all.

When to See Your Dentist

Call us if your dentures cause sore spots, clicking, or pain, if they crack or chip, or if you notice changes in your gums. Plan to have your dentures and mouth checked at least once a year even if everything feels fine.
