What Causes Dark Teeth After Using Peridex Oral Rinse?

Went to dentist yesterday and had oral evaluation. Dentist put me on Peridex oral rinse for two weeks.
He did not explain why. Used last night and could not sleep very well it tastes no bad. Can I rinse out before going to bed. Teeth are looking dark, will it come off after I discontinue use?

Hello,
Thanks for your query.
Some mouthwashes can even cause staining. This is due to a chemical called chlorhexidine gluconate — an antiseptic designed to reduce bacteria and remove plaque, both of which can lead to bad breath.
However, when regularly exposed to the teeth it can cause brown patches on the enamel because of a chemical reaction.
Some ingredients in toothpaste, such as the foaming agent sodium lauryl sulphate, can interact with the fluoride in mouthwash, and deactivate it

Chlorohexidine can produce tooth staining within about ten days of usage because it reacts with food additives which may be left on the teeth, particularly tannins, found in Coca-Cola, tea, coffee and red wine.
I do hope that you have found something helpful and I will be glad to answer any further query.
Take care

Hello thanks for consulting at hcm..

Peridex oral rinse is used for patients suffering from gingivitis.. It may cause staining of teeth and maybe little bit of taste alteration..But it is not permanent..

In the next visit, by getting oral prophylaxis-scaling and polishing, even the stains will be removed..So nothing to worry...

Please consult a periodontist for a check up and treatment..
