Need urgent HELP!!

[tensepatient]

I brush my teeth regularly but from last year I started to develop this white area around my gums and now it is spreading and discolouring my teeth as well. I don't smoke at all. Please suggest what is this and what should I do? Any replies would be appreciated.

You have plaque on teeth you need to be cleaned at the dentist soon as possible.

These are calculus or dental plaque. I guess you have bleeding on brushing too.
Its high time that you get it cleaned. I recommend a consultation with your periodontist.
