Dentures Not Fitting Properly

If you’ve just started wearing your first set of dentures, it might be hard working out whether or not the pains you’re experiencing is just your mouth adjusting or a sign that you are experiencing your dentures not fitting properly. But determining the difference between the two can be tricky, given that the symptoms are quite similar.

We look at some common signs of dentures not fitting properly, and some tips on what to do:

Dentures not fitting properly: Common signs


Ill fitting dentures can rub against the gums and cause inflammation, which over time, can lead to a condition called ‘stomatitis.’ This condition can make eating painful or uncomfortable and grow increasingly worse if the source of the problem isn’t fixed. Sores are common within the first four weeks of being fitted with new dentures, as your mouth is still adjusting to having a foreign object inside of it. But if the problem persists after one month, you may have to return to your dental prosthetist to see if the dentures are fitting properly.


If there isn’t a tight seal between your gums and your dentures, food can quickly become trapped underneath your dentures which can cause bacteria to accumulate and grow. Over time, this can lead to infections of the gums or existing teeth. Infections are also common in elderly patients who wear dentures during sleep as the bacteria accumulated can pass from the mouth to the lungs. If you suspect you have an infection, antibiotics and a new fit may be the right course of action.


Pain is to be expected in the first four weeks of having dentures, but if it persists it might be a sign that something is wrong. Dentures not fitting right can put uneven pressure on the gums and even cause bone loss to accelerate. Bone loss is to be expected with dentures, as the pressure on the jawbone will cause it to shrink in time. Due to this shrinkage, dentures will have to be refitted every one to two years.

Dentures slip

Dentures not fitting right? Slipping is the most common sign that your dentures may be too big. Dentures should fit securely in your mouth and should not slip side to side or fall out easily. If you find that your new pair of dentures slipping, get in contact with your local dental prosthetist immediately for a new fit.

Dentures not fitting properly: 3 tips and tricks

Dentures slipping? Try a dental adhesive

A good dental adhesive can be a lifesaver when it comes to feeling safe with your dentures. Designed to make it more difficult for dentures to slip out of place, an adhesive is a good option for patients who need that added bit of security. However, if you require adhesive to keep your dentures from completely slipping, it may be a sign that your dentures need replacing or relining. If you find that your dentures need more and more adhesive to stay in place, it’s advised you stop using the adhesive and contact your local dental prosthetist for a checkup instead.

Denture liners

Denture liners or cushions provide some relief by creating a soft barrier between the dentures and the gums. These can be a good temporary fix if you’re waiting to get your dentures relined or to help make the transition into wearing dentures easier. Liners are a good alternative to creams and glues as they don’t leave a residue on the dentures.

Denture relines

If your dentures are only recently starting to cause problems, it may be a sign that they need relining. This may be caused by normal wear and tear, fluctuating weight, or change in eating habits. Dentures that need relining may suddenly appear loose, or cause food particles to become trapped on top of your gums. Your dentures may require a soft reline – a dental prosthetist adds a pliable material to your dentures to help soften the impact it has on your gums– or a hard reline – a more extensive restoration.
