Diabetes mellitus, more commonly referred to as diabetes, is back in the limelight once again. Recent reports have projected numbers in Singapore to rise substantially over the next few decades, and an increasing proportion of patients are being diagnosed as young as 30 years old.


Diabetes is characterised by elevated blood sugar levels, and many know it to affect various parts of the body, including the feet (diabetic foot), eyes (diabetic retinopathy), kidneys (diabetic nephropathy), and nerves (diabetic neuropathy). But did you know that diabetes can also have crippling effects in the mouth? Below are four ways diabetes is harmful to your oral health and wellbeing.


Gum Disease: Diabetes significantly promotes the development of advanced gum disease, and rapidly accelerating destruction of the bone around the teeth. In advanced stages of gum disease, teeth tend to become loose and may even result in teeth loss, further encumbering eating and speaking.

Poorer Recovery: Diabetes impairs the body's ability to heal efficiently, and the mouth is no exception. This means that common dental procedures such as extractions, certain types of gum treatment, and even dental implants may take longer to heal in those with diabetes compared to a healthy individual. Compromised healing may also increase the risk of complications and infections. Just think about it, you’ve only just lost your tooth, and recovery is another war you have to fight.


Higher Risk of Tooth Decay and Fungal Infections: Many individuals with diabetes experience dry mouth due to lower saliva production. Saliva plays an essential role in the defence against tooth decay and oral infections due to its ability to neutralise acids (such as those found in soft drinks), antibodies to fight bacteria, and wash away food particles. Having less saliva means having less ability to fight tooth decay and fungal infections.


Denial of Gold Standard Treatment Options: If a patient has uncontrolled diabetes, current research suggests that it is recommended to avoid certain types of dental treatment. The reality is that patients with uncontrolled diabetes are at risk of tooth loss. Just imagine having lost your tooth, only to find out that you are unable to seek the gold standard tooth replacement option (dental implant) due to uncontrolled diabetes. The good news is that diabetes can be brought under control with treatment and advice from a qualified medical practitioner.


Understanding how diabetes affects oral health empowers individuals to take informed and proactive steps in preserving their dental wellbeing. It's crucial for individuals with diabetes to prioritise blood sugar management, maintain regular medical and dental check-ups, and practise good oral hygiene. By addressing these concerns, individuals can mitigate the risks associated with diabetes and enjoy a healthier smile and lifestyle.
