Despite what some patients think, dentures do not last forever. On average new dentures generally last for five to ten years before they need to be replaced. This is because your mouth changes shape over time and the comfortably fitting dentures you started out with, will not compensate for those changes. In this article, we are going to take a look at “how long do false teeth last?”.


Why Don’t False Teeth Last Forever?

As we get older, our gum shape and underlying jawbone change. Sometimes this is because tooth roots no longer stimulate the jaw. In other cases, there could be medical reasons for the change. When your new dentures are made, they are fitted to the dimensions and size of your jaw. And, just like your natural teeth, dentures are subject to wear and tear over time. But when your dentist is fitting dentures for you, they have no idea how your mouth shape might change in the future. This is why it is so important to go for regular checkups and ensure your false teeth fit comfortably.



How Long Do False Teeth Last?

The lifespan of your new dentures is usually determined by the denture type you wear. A good rule of thumb is to expect to replace your false teeth every five to ten years, but you should get a more accurate timeline from your dentist when you are fitting dentures:

  • Removable dentures usually last for around five years
  • Full dentures can be expected to last for between five and ten years
  • Partials usually need to be replaced every ten years. Some have been reported to last up to 15 years.
  • Flexible dentures usually last for five to eight years.


Relining False Teeth

Relining is recommended every two to three years, and can extend the lifespan of your prosthesis before you need to replace it. If you are experiencing irritation or sore spots, your dentist can make minor adjustments to the denture by injecting hard or soft relining material into the base. This reshapes it and gives you a more comfortable fit.


What Are The Signs Your False Teeth Need To Be Replaced?

  • Your previously well-fitting dentures are less comfortable or cause irritation
  • Your prosthesis is broken or damaged and can’t be repaired. Minor damages can often be repaired professionally, but this must be done by your dentist.
  • Small cracks have developed in your denture, which can allow bacteria to penetrate and give rise to infection.

Never attempt to repair false teeth yourself. Even the smallest adjustment can make a big difference and can damage your prosthesis and your soft tissue. Always speak to your dentist about repairs or at the earliest indication of discomfort so you can get a professional solution. When your dentures are new, they will cause some temporary discomfort but a week or two after fitting dentures you should be completely used to them.
