Please get your teeth checked for plaque or tartar removal.  After that Polishing if u feel that u need to whiten your teeth then you can do light cured composite laminates or porcelain veneers.  Feel free to consult Laser Smile Care Centre. God bless u.

The yellowishness of the teeth can be due to intrinsic or extrinsic stains..... in either case they are not removable by brushing alone and will need professional intervention...... if the stains are extrinsic, a session of teeth cleaning will be sufficient to remove them to restore gum health and a beautiful smile.... if the stains are intrinsic, procedures like bleaching, laminates/veneers will be able to help you to restore a better smile......
