Bacteria, virus-killing mouthwash

by | July 7, 2021

New Orasyl mouthwashes comes in two types.


Singapore-based medical and dental equipment supplier MediDent International has launched the first locally manufactured povidone-iodine mouthwash that can kill both oral bacteria and viruses. Povidone-iodine, the active ingredient in Orasyl Orange is said to be particularly effective against COVID-19, and has also been proven to keep other viruses and oral bacteria at bay after each use while promoting good oral hygiene health.

Orasyl Orange is a specially formulated anti-viral and anti-bacterial mouthwash that contains the active ingredient of one-percent povidone-iodine to treat the build-up of dental plaque, gingivitis, fungi, protozoa parasites, yeasts, gram-positive and negative bacteria, SARS, MERS, COVID-19, measles, mumps, herpes, HIV, influenza, rota-viruses, HFMD and Ebola. The active iodine agent works to destabilise the membrane of a virus or bacteria by inducing pore formation, causing cell leakage and killing them within seconds.

On the other hand, Orasyl Green is an antiseptic, germicidal mouthwash that includes chlorhexidine digluconate, providing users with a broad virucidal spectrum of protection against bacteria, germs, inactive viruses and for overall better oral health. The chlorhexidine digluconate binds to negatively charged bacterial cell walls to affect the osmotic equilibrium of the cell to inactivate any germ, virus and gram-positive and gram-negative bacteria. Additionally, chlorhexidine mouthwashes such as Orasyl Green mouthwash have been shown to reduce salivary bacterial load by 97 percent for 60 minutes at a time, according to the company.

Both types of mouthwash offer the added benefit of stabilising the mouth pH and reducing dry mouth syndrome due to the addition of red algae. They are also mint-flavoured and are soothing, refreshing and alcohol-free. Despite their strong green and orange hues, both mouthwashes do not leave a stain on teeth and tongue. Users simply have to gargle and rinse with five to 10ml of the solution for 30 to 60 seconds, up to three times a day.


Both Orasyl Orange and Green are available in 100ml, 250ml and 500ml and costs from S$5.50 to S$23. They can be bought at Orasyl’s website, Shopee, Lazada or Q10 or in-store at several Nuffield Dental clinics.
