Please tell me some ways to get rid of peridex (chlorhexidine gluconate) staining?

Dental cleaning: A hygiene visit at your dentist's office can remove the Chlorhexidine staining from your teeth. It needs to be scaled and polished off.

PERIDEX (chlorhexidine gluconate): Peridex (chlorhexidine gluconate) is an effective in treating gingivitis, it is both bacteriocidal for immediate effect and bacteriostatic for long term effect where it is absorbed into a protein film called pellicle on the enamel. Here it inhibits bacterial plaque called biofilm from organizing until the next homecare session aimed at disrupting this biofilm. The downside it causes staining requiring professional cleaning.

Peridex (chlorhexidine gluconate) staining: A professional cleaning from your dentist or dental hygienist should remove most or all the staining. However, some old acrylic or even tooth colored bonded composite fillings, especially those that have pits, scratches or defective margins may need to be retouched or replacemed.
