It includes procedures like teeth whitening, veneers, smile makeover, orthodontics, frenectomy, gingival surgery, etc.

Gingivitis- The inflammation of gums is called as gingivitis. The main signs include reddish gums, bleeding from gums, bad breath, etc.
Halitosis- Halitosis or bad breath is the sign of foul odor from mouth. It commonly occurs due to poor maintenance of oral hygiene, gum diseases, tooth decay, etc.
Immediate dentures- The dentures that are placed immediately after tooth extraction are immediate dentures. Unlike the conventional dentures, the impression making and all laboratory steps are done before the tooth extraction.
Impaction- The tooth that fails to erupt in
