flexible dentures procedure, types, pros, cons & cost

What are Flexible Partial Dentures?

Losing teeth is a common problem, and conventional dentures were for a long time the least expensive solution. 

Usually, this dental appliance is constructed from a metal plate with acrylic gums and porcelain or composite resin teeth. 

Flexible partial dentures have recently been made available as a new alternative on the market. This type of restoration is claimed to flex and fit into your mouth more comfortably.

Flexible partial dentures are only appropriate for people who still have some of their natural teeth, as the name suggests. 

There is currently no adaptable option available for people who are completely toothless. 

These dentures are softer and more flexible than standard dentures, which addresses many of the problems associated with wearing dentures in general. 

They are made from a flexible, lightweight material called thermoplastic nylon resin.

How Do Flexible Dentures Work?

They work by providing a comfortable, natural-looking, and functional solution for individuals with missing teeth or partial tooth loss. 

They are designed to replace missing teeth while adapting to the unique contours of a patient’s mouth. 

The Process is as Follows:

1. Assessment and Consultation

A dentist or a prosthodontist assesses your oral health and discusses your specific needs and goals.

2. Treatment Plan

This plan outlines the number of missing teeth, their location, and the best way to restore your smile. 

Flexible dentures are most commonly used to replace missing teeth in the upper or lower arches, either partially or completely.

3. Impressions and Measurements

To create customized dentures, precise impressions and measurements of your mouth are taken. 

This involves taking a dental mould and digital scanning technology to capture the exact shape and size of your gums and any remaining teeth.

4. Design and Fabrication

Your flexible dentures are made to order in a dental laboratory after impressions are taken. 

This design ensures that the dentures will fit in seamlessly with your current dental structure by taking into account the colour, size, and shape of your natural teeth.

5. Material Choice:

The most common material used to create flexible dentures is thermoplastic nylon resin. 

This substance was selected due to its biocompatibility, durability, and flexibility. It enables the dentures to be flexible, pleasant, and durable.

6. Fitting and Modifications:

You go back to the dentist for fitting once the flexible dentures are finished. 

The dentist will examine the dentures in your mouth for fit, comfort, and look. To achieve a tight, secure fit, any necessary alterations are made.

7. Wearing Flexible Dentures

You can start wearing your flexible dentures once they have been correctly fitted. The flexible material conforms to the shapes of your mouth to fit securely and comfortably. 

Because they are less prone to irritate or aggravate sore places, many individuals find flexible dentures to be more comfortable than conventional acrylic dentures.

8. Care and Maintenance:

Maintaining and caring for your flexible dentures properly is crucial to ensuring their durability. 

This entails routine washing with a gentle denture cleanser or soap and a soft toothbrush. 

Additionally, it's essential to take off your dentures at night so that your gums may relax.

Pros of Flexible Dentures

Let's look at some of the benefits of these dentures-

1. They do not easily break.

Dropping dentures can frequently result in a crack because they are composed of a tougher material. 

Dentures that break require expensive and time-consuming replacement. Partials that are more flexible have more give and can sustain falls better.

2. Soft than conventional dentures

Regular dentures are made of hard material, which can irritate your gums' sensitive tissue. You may stop wearing your dentures on a regular basis as a result of this discomfort.

Softer materials used in flexible partial dentures make them easier on your gums. Dentures might be worn all day long as you take pleasure in life's best moments, such as scrumptious meals with loved ones.

3. Do not need metal or glue

For a number of reasons, metal can be hazardous, especially when attempting to board a plane! 

However, removing metal from your mouth also has the advantage of preventing gum irritation and redness, which are two common side effects of metal consumption. Traditional dentures can become painful as a result of this.

Did you know that the glue used in dentures can also hurt your mouth's soft tissues? Because flexible partials don't need adhesives, there may be less mouth irritability.

4. Aesthetically blend with your natural gums

The flexible pink material that makes up flexible partial dentures frequently lets the gums peek through. Unlike other kinds of dentures, this one allows you to smile more naturally.

5. Faster to produce

Traditional dentures require at least 4 appointments and 3–to 6 weeks for preparation. This excludes the tooth extraction procedure, as well as the additional appointments and time needed. 

The entire process might take up to ten weeks once you include the additional time. This can be quite draining and complicate your life needlessly.

Cons of Flexible Dentures

There are also a few disadvantages to keep in mind: 

1. Bacteria accumulation

Flexible partial denture material can be susceptible to bacterial growth. Bacterial growth is encouraged by the material's softness and flexibility. 

Because of this, it's crucial to maintain good oral hygiene and to clean your partial dentures every day. Gingivitis and gum disease can result from failing to do this.

2. Incompatible with patients with a history of severe periodontitis 

Flexible ridges' edges that frequently come into contact with food or drink can provide a breeding ground for bacteria. 

Additionally, since flexible dentures are simple to take out and replace, contamination risk might be increased by doing so frequently. 

Patients who have a history of gum disease or are at risk for developing it should be cautious about wearing flexible dentures since germs can grow there easily.  

3. Not repairable

Although flexible partial dentures are far more difficult to break than conventional dentures, they are more difficult to fix. It could be necessary to replace the entire set if you break them.

4. Not long-term

For those seeking a tooth replacement solution that feels more natural and requires less upkeep, flexible partial dentures give a less permanent feel.

Cost of Flexible Dentures

On average, you can expect the price range to be between INR 15,000 and 40,000 or more, per arch. 

This cost varies depending on the location of the clinic, the complexity of dental restoration needed and the materials used.


In conclusion, flexible dentures provide patients in need of dental restoration with a comfortable, dependable, and realistic-looking option. 

Even though they might cost more upfront, the long-term advantages they offer, such as increased quality of life, frequently surpass the original outlay.
