New Dentures or just a Reline?

Patients often present at my clinic with dentures that started off fitting well and slowly got worse in their ability to function well under normal usage. This is often the result of bone resorption in the jaw.


Our bones are constantly changing on a molecular level and bone remodeling happens naturally in order to maintain bone strength.

Bone absorption is the process where bone tissue is broken down and calcium is transferred from bone to blood. It decreases bone mass only to be built back up again in a process called ossification.

In our youth, ossification trumps resorption but unfortunately the opposite applies as we get older. As resorption happens in our twilight years, our bone mass decreases which can result in the loosening of your dentures.


Instead of getting new dentures made, which can be costly, the patient can benefit from a denture reline. At a fraction of the cost, a reline is the adjustment of the denture plate that comes into contact with the gums and palate. The patient has a choice of 2 broad material types – hard and soft.


A soft reline is made from squeezable silicone material that is most suitable for patients with sensitive gums. Although not as durable as the hard option, the soft reline beds in quicker and eases the symptoms of ill-fitting dentures.


A hard reline is made from the acrylic resin which your original denture was made from and it’s benefits include durability and function. A hard reline will make your dentures feel as they were when they were first fitted and will certainly last longer than the soft option. If you present to me with sores from your ill fitting dentures I will most likely give you a soft reline, letting your sores heal and then replace with the hard option.


We look forward to speaking to you about how relining your old dentures can help you with restoring the functionality you expect from your dentures. Call us on 01- 8359296 to book your free consultation.

Dentures and the fight against Covid

By this stage, we have mostly all had our Covid jabs and boosters and are doing our part in the fight against this insidious disease by wearing masks in public places and keeping social contact to a minimum. But did you know that one of the best ways to help our bodies maintain a good fight against Covid-19 is to keep our mouths clean?!


Research over the past 2 years shows an undeniable link between poor oral hygiene and one’s ability to fight against Covid. Covid patients with gum disease show a weakening of immunity against Covid and those patients with gingivitis or periodontal disease are 9 times more likely to die of Covid.


To understand why this link exists, we need to understand that bacteria and other microorganisms can have easy access to our blood vessels if they are lurking around the gingival sulcus- that part of our tooth that meets the gum. Once in our blood vessels, these microorganisms can then flow around the body, settling in various organs and effectively making our body’s battle against Covid that bit more challenging.


I have re-opened the debate on denture hygiene and the importance of keeping dentures well fitting and functioning. I firmly believe that a poorly made denture can irritate gums and introduce pathogens into the bloodstream through sores created by the denture. Not to mention the surface of an old or poor quality denture can be porous and offer a home to microorganisms which we know undermines the overall health of society’s most vulnerable.


Maintaining your ability to fight Covid as best you can puts a renewed emphasis on getting the right Denturist to take care of you and your loved ones. The National Denture Centre has the perfect combination of technical know-how and clinical experience to ensure we bring the best result to our patients. With the clinic and laboratory under one roof and our clinicians and technicians working side by side, the best results can be achieved in the minimum amount of wait time for the patient.



At the National Denture Centre, we strive for two distinct outcomes for our patients – superior FIT and FUNCTION.

FIT – The dentures that come out of our laboratory must fit like a glove. They must offer that level of comfort where the wearer doesn’t feel the need for adhesive and where there is no movement, causing gum sores.

FUNCTION – they must function every bit as well as when the patient had their own teeth, eating and chewing anything they want and not allowing food to get lodged underneath.


Being a patient of the National Denture Centre means you are partnering with a Denturist that has a passion for your oral and dental wellbeing. We love what we do because we love changing lives and look forward to taking your call to organize your free consultation.

The lifespan of a denture

A question I often get asked during a consultation is “How often do I need new dentures?” or “How long will my Dentures last?”

It is advisable that your dentures are changed every 5 years. Within that time, after approximately 2.5 years, a reline should be done.

‘Why do I need new Dentures when my dentures seem fine and I’ve had them for years?”. Well, what people don’t realise is that bone resorption happens at a much faster rate when there are no teeth present. This resorption causes the dentures to become loose – like wearing a slip-on shoe a few sizes too big. Hence the reason why people resort to using adhesives in order to keep them in place. They can also irritate the gums by rubbing on them, which can throw the bite off, which in turn can lead to a denture breaking or worse still lead to TMJ problems such as neck pain, ringing in the ears…..the list goes on.

From an oral hygiene point of view I recommend changing dentures every 5 year as they become porous or scratched (products used to clean your dentures with high contents of bleach only speed up the process). This surface porosity becomes a perfect environment in which bacteria can live, essentially rendering your denture a pathogen your body has to fight against. Studies have found that people with systemic health issues such as heart problems, COPD, Diabetes, respiratory diseases, can find it difficult to get on top of their ailment when they are also fighting against a dirty denture.

Denture teeth also wear down over time which cause patients to become over-closed and can also lead to TMJ problems. Aesthetically, this can cause lines on the face such as a downward smile when biting. Women can find it difficult to put on lip stick. They can also start to notice sinking cheeks or an inability to see top teeth anymore. Depending at your stage these are all issue that can be fixed by renewing your dentures every 5 years.

If you are nearing your 2.5 year reline stage or your 5-year renewal mark, call now to book your free consultation on 01 8359296 before it’s too late and you find yourself in a denture disaster.  We are now living in a world where prevention, in health terms, is so important. Let’s start with your Dentures!!

Denture Stomatitis

I see patients on a daily basis who are unaware of the importance of taking their dentures out at night. I can tell straightaway which patients leave their dentures in all the time. Tissues are red, swollen, and angry. I try to get them to imagine walking around 24/7 with their shoes and socks on, going to the gym, stuffing some food in their shoes while walking around a little longer, a day, a week, a month……. One can only imagine how that would feel and smell!!! One’s mouth is no different. But the serious implications of this is still very much unknown to my clients – Denture Stomatitis, Candidiasis aka thrush, cancer all associated with lack of oral hygiene and oral care.
