I have been struggling with gingivitis for a few years now. I try to go the dentist every 3 months for cleanings to stay on top of it but it doesn't always happen. I went about a week ago for a cleaning and a few days later I have noticed that I am experiencing a burning/tingling sensation in gums/tongue. I usually don't pay too close attention to what my gums look like and I want to know what healthy gums look like. Is this a picture of healthy gums? Is the white towards the bottom where the roots of your teeth would be normal?
