What is a denture reline and why would I need one?

A denture reline, also referred to as a denture realignment, is a thin permanent coating applied across the fitting surface of your denture where it makes contact with your gums. The purpose of a denture alignment is to seal off any gaps that may have developed over time thus restoring its original snug fit.

Why is this important? Space between your denture and gums can allow food particles to become trapped. In addition, the gaps between your gums and the denture cause instability or denture ‘rocking’, making your denture vulnerable to cracking and breaking under the pressure of chewing.

Having your denture relined compensates for the inevitable changes in your mouth that occur due to ageing, changing health status, weight loss or normal wearing away of denture surfaces. A denture reline or denture adjustment not only restores comfort and stability but is essential for preserving the life span of your denture and your beautiful smile.

However, while denture relines optimise the life of your denture, maintaining their best fit, comfort and appearance, eventually new dentures will be needed. Contact our denture clinic today to find more about our Tweed Heads denture reline service.

When do I need a denture reline?

Your prosthetist recommends a denture reline every two years for a full denture, unless your circumstances demand one earlier. Regular annual checkups with your prosthetist ensures maintenance is implemented when required and denture repairs performed when necessary.

Signs you need a reline include food becoming stuck in gaps between the denture and your palate and gums, or you develop rubbing or sore spots on your mouth and gum tissue. Another sign a denture reline is due is when your denture feels insecure and loose or dislodges while laughing, singing, eating or speaking.

Types of denture relines

The type of denture reline or denture realignment for you will be guided by your prosthetist who will prescribe one of the three types after assessing your particular needs. Not all dentures are suitable for realignment. While acrylic partial dentures and acrylic full dentures can be relined, flexible dentures cannot. And only the acrylic section of the chrome denture can be relined.

Hard denture reline

Ideally, a full denture should have a hard reline every two years unless your prosthetist recommends one earlier. This is part of the regular maintenance to ensure the optimal life span of your denture.

The hard relining of denture protheses restores the dentures’ snug fit and delays having to replace them with a new one. The hard reline involves applying a pliable material over the denture surface before trying it in your mouth to determine where adjustments need to be made.

Once this is established, the pliable material is replaced with acrylic restoring the denture’s close fit and durability.

Temporary denture reline

If your gums have become sore and inflamed over time, your prosthetist will recommend a temporary denture reline. Neglecting to have regular denture relines can often be the cause of this deterioration. Your dental prosthetist relines the denture with a medicated material as a temporary measure until the gums have healed. Then, either a hard reline can be applied, or new dentures can be made.

Because the temporary reline is not heat cured like hard relines, they can become discoloured or porous, harbouring bacteria and leading to problems like halitosis or bad breath. The expense and inconvenience of temporary denture relines can be avoided by regular maintenance of your dentures.

Soft denture reline

A soft denture reline is recommended if your gums are tender or sensitive. Sensitivities can lead to sore spots and discomfort when eating. The soft reline is a perfect way to give your mouth and gums time to heal and adjust to wearing dentures. Your dental prosthetist applies a soft waxy or rubbery material to cushion your gums.

The soft denture reline can last up to two years.

While denture relines have a place in extending the life and comfort of your dentures, dentures do not last forever. They must eventually be replaced. When the teeth become worn and aging effect of over-closure (loss of space between the nose and the upper lip) develops, it’s time for new dentures.

What is the denture reline procedure?

With a little forward planning, your denture reline can be done within the day minimising the inconvenience of time without your teeth.

Firstly, you will attend an early morning appointment for impressions to be taken of your mouth.

You leave your denture with us to do the denture relining during the day.

When you attend your afternoon appointment (around 3.00-4.00pm), we fit your relined denture.
