Thanks for asking the query,
According to your clinical symptoms i suppose that you have developed localised periodontitis
in your lower front teeth region.
Its is very nice to hear that you have quit with the habit.
Go for complete mouth scaling and polishing and curettage.
Take lukewarm saline and antiseptic mouthwash rinses.
Maintain a good oral hygiene
brush twice daily with a soft bristle toothbrush.
Take a course of multivitamin
Hope you fins this as helpful,
