7 Signs It’s Time to Replace Your Dentures

Dentures are a standard solution for individuals who have lost their natural teeth. They provide the ability to eat, speak, and smile with confidence. However, like any dental appliance, dentures have a limited lifespan. Over time, they can become worn, ill-fitting, and uncomfortable. It’s essential to recognise the signs that indicate it’s time to replace your dentures. This article will discuss seven common signs indicating it’s time for a denture replacement.

1. Loose or Ill-Fitting Dentures

One of the most apparent signs that dentures need to be replaced is when they become loose or ill-fitting. If you notice that your dentures are shifting or slipping when you speak or eat, it indicates that they no longer fit properly. Ill-fitting dentures can cause discomfort, difficulty chewing, and even mouth sores. It’s essential to visit your dentist to have your dentures evaluated and replaced if necessary.

2. Gum Irritation or Inflammation

If you experience persistent gum irritation or inflammation while wearing your dentures, it may be a sign that they must be replaced. Over time, dentures can become worn down and develop rough edges that irritate the gums. Also, ill-fitting dentures can pressure specific gum areas excessively, leading to inflammation and discomfort. Replacing dentures will help alleviate these issues and improve oral health.

3. Changes in Facial Appearance

Dentures not only restore your ability to chew and speak but also play a significant role in maintaining the structure of your face. Over time, as dentures wear down or become ill-fitting, they may fail to support your facial muscles. This can result in changes in your facial appearance, such as a sagging or sunken. If you notice such changes, it’s time to consider replacing your dentures to restore your natural facial aesthetics.

4. Difficulty Chewing or Speaking

One of the primary functions of dentures is to restore your ability to chew and speak properly. If you are having difficulty chewing certain foods or if your speech has become slurred or unclear, it may be a sign that your dentures are no longer functioning optimally. Ageing dentures can lose their ability to provide the necessary bite force and proper alignment, making eating and speaking challenging. Replacing your dentures will help improve your chewing and speaking abilities.

5. Persistent Bad Breath

Persistent bad breath, also known as halitosis, can indicate that your dentures must be replaced. Over time, dentures can accumulate bacteria, food particles, and plaque, leading to an unpleasant odour. Despite regular cleaning and maintenance, old dentures may become more prone to harbouring bacteria and causing bad breath. If your bad breath persists even after thorough cleaning, it’s time to consider replacing your dentures for improved oral hygiene.

6. Visible Wear and Tear

Like any dental appliance, dentures are subject to wear and tear over time. If you notice visible signs of wear on your dentures, such as cracks, chips, or worn-down teeth, it indicates that they must be replaced. Worn dentures affect their functionality and can cause discomfort and increase the risk of oral health issues. Regularly inspect your dentures for signs of wear and consult your dentist if you notice any significant damage.

7. Age of Your Dentures

Lastly, the age of your dentures is essential when determining if it’s time for a replacement. Dentures typically have a lifespan of 5 to 10 years, depending on the quality of materials and how well they are cared for. If your dentures are approaching or have exceeded their recommended lifespan, you should schedule a consultation with your dentist to discuss the possibility of getting new dentures.


Dentures play a crucial role in restoring your smile and oral functionality. However, they are not meant to last a lifetime. Recognising the signs that indicate it’s time to replace your dentures is essential for maintaining your oral health and overall well-being. If you experience any of the signs mentioned in this article, it’s necessary to consult your dentist for a comprehensive evaluation and to discuss the possibility of getting new dentures. Remember, a well-fitting and adequately functioning set of dentures can significantly improve your quality of life.
