Sir we need to understand about your daily habits such as less drinking water, teeth brushing techniques, have you undergone any dental scaling or thorough cleaning of your teeth, all above factors u will understand after you show to a dentist... Mostly we need to assess your dental hygiene conditions... That is only the main factor so don't ignore this .. thank you...
