Dentures or dental prosthesis are this miraculous device that is supposed to substitute the missing teeth in your mouth and give you the possibility to chew, smile and speak in a normal way. Although, many patients around the world suffer from unstable dentures and are disappointed with the results. 

So we decided to write this article, to explain to you why
your dentures are not stable and which options you have
to fix them.

Unstable dentures: 


The stability of your denture comes from a perfect contact of the prosthesis with your bone and tissues. The more space there is between your teeth tissue and your denture, the less your denture is stable. 

Stability also depends on how much your bone is resorbed, because the less bone quantity, the less stable is your denture. 

For the best stability, your dentist has done two impressions for each of your mouth arch.

– A primary impression in which the general surface of your bone tissue is registered.


– A secondary impression that registers the exact details of the teeth structures and their surrounding tissues.

So mainly the instability in your dentures can emerge because: 

  • Your bone tissue still needs time to adapt to the new denture.
  • Your bone is very resorbed.
  • Mistakes in precision can happen during taking impressions.

It is up to your dentist to decide the cause of the instability of your denture and adjust the problem.

Solution ✓:

Use denture adhesive: if your denture is unstable, applying a dental adhesive paste can help you, but it is not recommended to use it for a long period of time. You can find many good adhesive pasts on the market, like: Fixodent©, Sea bond©, Novafix©But do not use these products before consulting your dentist.

The denture is too tight:

As we explained earlier, stability comes from a perfect contact of your denture with your bone tissue. Sometimes this contact can be too tight and therefore your denture presses too hard on your bone tissue. 

Solution ✓:

This stability is considered good, and your bone tissues have the ability to adapt to the new denture, just like your feet can adapt to new shoes. But if you still feel uncomfortable or feel pain after a few first weeks, go back to your dentist, so that he can adjust your dentures.

Denture Injuries:

Dentures are often made of resin, which is a very hard material that is not flexible. Resin, if not polished well, can be a little sharp and rough for the sensitive mouth areas.

Sometimes your dentures can be very well polished but still injure you because its not very well adapted in that area and the excess needs to be removed.

To distinguish between the two problems, you need to visit your dentist.

Solution ✓:

While waiting for the appointment, you can take some denture injury ointments like Pansoral© or Arthrodent© 

Classic dentures that are made of acrylic resin, which is a non flexible and allergic material. We advice you to read more about the new generation of non allergic, flexible dentures, in the following article: Flexible denture advantages.

How to take care of your dentures:


Your dentures need to be taken care of; so that they won’t loose their stability: 

  • Eat soft foods:

Sticky food like gum and caramel will cause instability to your dentures.

  • Eat slowly:

Avoid making big bites and chew slowly and using both sides of your mouth. 

  • Avoid sleeping with dentures:

You need to give your mouth tissue rest time at night.

  • Clean your dentures regularly:

-You need to clean your dentures with a tooth brush.

-Soak your dentures overnight in special denture cleaners.

-Do not clean your dentures with bleach.

  • Clean your mouth regularly:

even if you don’t have teeth, you still need to clean your mouth regularly.

Voice pronunciation changes after new prosthesis: 

One of the main elements that controls your voice are your tongue and teeth and lips,

The form and length and angulation of the new denture teeth result in a different pronunciation of certain letters. Also, your tongue and lips position and movements change after that the new denture is set between them, which changes the way you pronounce letters.
