Silent health clues the gum colour indicates: Doctor explains

We often focus intensely on the brightness of our teeth, as though a perfect smile is defined only by whiteness. But the real foundation of that smile lies much deeper in the gums. Healthy gums are not only essential for oral health but are also closely linked to overall well-being. Dr Merlin Thomas of the Indian Dental Association, Thiruvalla, explains more on changing gum colours, diseases and more. 

Under normal conditions, gums are firm and light pink in colour. But what if that familiar appearance begins to change?
Shifts in gum colour or texture can sometimes be more than just a cosmetic concern. They may point to anything from genetic variations to serious health conditions that deserve attention. If your gums start to drift from their natural pink tone and appear brown, red or even bluish, there could be several possible reasons behind it:

a) Pigmented gums:
Just like skin tone, the colour of the gums is also influenced by melanin pigment. Due to the natural presence of melanin in the body, gums may appear brown or dark brown in colour. This is more common in individuals with darker skin tones. While some may prefer to have pink gums for cosmetic reasons, this variation is generally harmless.

b) Colour change due to smoking (Smoker’s melanosis):
Tobacco use can lead to changes in gum colour. Nicotine stimulates melanocytes, which in turn increases melanin production. This may appear as patches or may involve the entire mouth. It can also be spotted on the lower lip and inner cheeks.

c) Medication:
Certain medications can also cause changes in gum colour, as they may increase melanin accumulation, drug deposition, or pigment formation. Drugs such as chloroquine, quinine, minocycline, zidovudine, chlorpromazine, ketoconazole, bleomycin, and cyclophosphamide can cause oral pigmentation. Phenothiazines and phenytoin may cause blue, bluish grey or brown patches. Amiodarone can also cause greyish pigmentation.

d) Periodontal diseases:
Red, swollen gums; bleeding; a foul smell; loose teeth; pus discharge; and gum recession are common signs of this condition. As plaque accumulates, bacterial infection can trigger inflammation and lead to bone loss. This condition is also linked to systemic diseases such as heart disease and diabetes. Therefore, maintaining good daily oral hygiene is essential.

e) Addison’s disease:
Certain changes in the mouth may indicate underlying hormonal disorders. In Addison’s disease, the adrenal glands produce insufficient hormones. As a result, ACTH levels rise, leading to dark pigmentation of the gums, tongue, and lips. In some cases, this may even be one of the earliest signs of the condition.

f) Workplace exposure to heavy metals (Heavy metal pigmentation):
Exposure to heavy metals such as lead, bismuth, mercury, silver, arsenic and gold can lead to changes in gum colour. In cases of lead poisoning, a bluish or reddish line known as the `Burtonian line' may appear along the gums. Likewise, exposure to silver may cause a violet or greyish blue discolouration of the gums.

g) Amalgam tattoo:
If a bluish or greyish patch is spotted near a silver filling, it may indicate an amalgam tattoo. This occurs when a small fragment of the filling material becomes embedded in the gum tissue. It is, however, harmless in nature. With the increased use of tooth-coloured filling materials in modern dental treatment, such cases are now seen less frequently.

Cancerous signs
Certain subtle changes in the mouth may, at times, be early indicators of cancer. Persistent red or white patches, non-healing ulcers, unusual bleeding, a persistent lump, difficulty chewing or swallowing, and changes in voice should all be taken seriously. Any symptom that does not resolve within two weeks warrants a dental evaluation.

The gums are not merely the framework of your teeth, but also a reflection of your overall health. While most colour changes may be harmless, new patches, swelling, or bleeding should never be ignored. Consulting a dentist in such cases is important. Caring for your gums today is an investment in securing your future overall well-being.
