Understanding Gum Disease: Prevention and Early Signs

Gum disease affects nearly half of adults over 30 and is the leading cause of tooth loss. Here is how to recognise it early and stop it in its tracks.

Periodontal disease — commonly known as gum disease — is a bacterial infection of the structures supporting your teeth. It progresses in stages: from mild gingivitis to advanced periodontitis, and without treatment, it ultimately leads to bone loss and tooth loss. The good news is that in its early stages, gum disease is entirely reversible.

Gingivitis: The First Stage

Gingivitis is the earliest and mildest form. It causes redness, swelling, and bleeding — particularly when you brush or floss. Many patients dismiss these signs as normal, but healthy gums should never bleed. Gingivitis is caused by plaque accumulation at the gum line and is fully reversible with improved home care and a professional clean.

Periodontitis: Advanced Disease

If gingivitis is left untreated, the infection spreads below the gum line into the bone. Pockets form between teeth and gums, providing ideal conditions for bacteria to multiply. At this stage, the damage to bone and connective tissue is irreversible, though it can be halted with professional treatment.

Periodontal disease has been linked to cardiovascular disease, diabetes, and adverse pregnancy outcomes. Your gum health is an indicator of your whole-body health.

Risk Factors You Should Know

Certain factors significantly increase gum disease risk. Smoking is the most significant modifiable risk factor — smokers are twice as likely to develop periodontitis as non-smokers, and their response to treatment is slower. Diabetes, hormonal changes during pregnancy, and certain medications that cause dry mouth also elevate risk.

Treatment and Prevention

The cornerstone of prevention is excellent daily hygiene — brushing twice daily and flossing once. Regular professional cleans remove the tartar that home brushing leaves behind. If gum disease has already developed, we offer a range of treatments from deep cleaning (scaling and root planing) to surgical options for advanced cases.

Early detection is everything. A routine check-up every six months allows us to catch and reverse gum disease before it progresses.
