For the past couple of days I’ve noticed that one part of my gums has become slightly white in colour and is spongy to the touch. It does not pain, but I’m worried that it might lead to a bigger issue. What could it be and should I see a dentist right away?

There could be many reasons for this, so it is difficult to give a definitive answer. One of the most common reasons for gums appearing white near the margins of the teeth could be poor oral health leading to accumulation of food debris and plaque. This can be easily removed by a professional cleaning done by a dentist or hygienist, and with proper brushing techniques.

If the white patches are more widespread it could be indicative of a fungal infection or more serious condition such us leukoplakia. It is important that you visit a dentist for a correct diagnosis and treatment.
