Help Protect Yourself from Aerosol Generated Procedures (AGP)

OraWize+ is an oxidising mouthwash for pre-procedural use (before treatment).   The unique mouthwash has been developed to both reduce the risk posed by aerosol generating procedures as well as to assist biofilm management during standard and specialist dental treatment. The active ingredient, Hypochlorous acid (HOCl), is part of a group of small molecules known as reactive oxygen species (ROS); and is the same chemical produced by the human immune defence system to kill bacteria and viruses whilst fighting infection.   Our unique manufacturing process stabilises HOCl to produce an effective intraoral mouthwash that is non-sensitising, non-irritating and not harmful…

  • Oxidising mouthwash that physically destroys oral microbes.
  • Kills 99.9999% of harmful organisms before, during & after treatment.
  • Potent biocidal action helps minimise the risk of aerosol generating procedures.
  • Tested to stringent European standards including BS EN 14476.
  • Non-toxic, biocompatible, no acrid taste or odour

The Science

OraWize+ is specially formulated to avoid the dangers inherent in many regular mouthwashes— including the immediate effects of chemical burns and the long-term toxic risks to mammalian cells such as mutagenicity, cytotoxicity and reproductive toxicity in humans.
The active ingredient, Hypochlorous acid (HOCl), is part of a group of small molecules known as reactive oxygen species (ROS); and is the same chemical produced by the human immune defence system to kill bacteria and viruses whilst fighting infection.
Our unique manufacturing process stabilises HOCl to produce an effective intraoral mouthwash that is non-sensitising, non-irritating and not harmful to biological tissue.

See how the human immune defence system produces HOCI to kill invasive organisms:

Bacteria enter the body when the skin is broken, stimulating a response from the human immune defence system.

A type of white blood cell called Neutrophils migrates to the bacteria in a process called ‘chemotaxis’.

Neutrophils surround the bacteria and release Hypochlorous acid (HOCI) to kill it.

How is OraWize+ more effective than conventional mouthwash?

Effectively removes debris

Boosts performance to flush out debris.

No acrid taste or odour

Provides a better patient experience with none of the unpleasantness associated with solutions containing bleach, EDTA or Chlorhexidine.

Easier to manage

Staff training is more straightforward with OraWize+’s premixed non-toxic solution. No need to mix hazardous chemicals or deal with complicated dilutions.

Protect your business

Protect your business from litigious claims by patients or staff relating to accidental chemical burns, including toxic damage to eyes, nose, throat or skin.

Long-term benefits for your practice

With no short or long term health impacts when used as recommended, clinical outcomes will always be more positive when using OraWize+.

What is Hypochlorous acid (HOCl)

Hypochlorous acid (HOCl) is part of a group of small molecules known as reactive oxygen species (ROS). HOCI is synthesized by neutrophils (white blood cells) during phagocytosis of antigens (1).

The molecule kills and inhibits the growth of a broad range of microbes including Gram-positive and Gram-negative microorganisms, aerobic and anaerobic bacteria, virus, yeast mould and fungus — all without causing harmful side effects such as irritation of the mucosa or pigmentation on tooth surfaces or restorations.

HOCl also has essential anti-inflammatory benefits (2, 3, 4).

Why is OraWize+ dental mouthwash so safe for humans?

OraWize+ is biocompatible
Hypochlorous, the active ingredient in OraWize+ is found in the body’s immune defence system and is not harmful to human tissue.

No short term health risks
OraWize+ is not harmful if it comes into contact with skin, the eyes, or even if accidentally ingested.

No long term health risks
OraWize+ is non-cytotoxic and non-mutagenic. There is no risk of long term damage to cells, DNA or adverse effects on the reproductive system.

Keeps staff and patients safe
OraWize+ removes the hazards associated with conventional highly toxic products including

  • danger to mammalian cells;
  • secure storage requirements;
  • the need for careful handling procedures;
  • dealing with complicated dilution formulas and 2-part processes; and
  • staff training in hazardous chemical use.

OraWize+ : Biocidal, oxidising pre-treatment Mouthwash.

Evidence summary:

OraWize+ is a stabilised soluBon of Hypochlorous acid (HOCl) which is a naturally occurring biocide, produced by mammalian neutrophils as an essenBal part of the phagocytosis of bacteria and viruses. (1)
Hypochlorous acid (HOCl) is part of a group of molecules known as reacBve oxygen species (ROS). It’s primary method of acBon is the physical oxidisaBon of 99.9999% of known micro-organisms.

The OraWize+ molecule’s neutral charge enables it to rapidly adhere to and penetrate the microbial cell. Once within the cell, the HOCl disrupts replicaBon and protein synthesis rapidly killing the bacterium or virus.
OraWize+ is one of the most efficient biocides known and is 80-100 Bmes more anBmicrobial than sodium hypochlorite (bleach). (2,3,4)

This fundamental chemical / physical nature of this action means that neither patent sensation nor microbial resistance are issues.

OraWize+ is effecBve against all of the common oral commensals and pathogens, Gram-posiBve and Gram- negaBve, aerobic and anaerobic bacteria, fungi and spores.
OraWize+ has been shown to be effecBve against enveloped and non-enveloped viruses (5). Tests against the Feline Calcivirus, a commonly used, hard to kill, subsBtute for Norovirus, showed a 5 log reducBon in less than 60s (6).

Specific tests against SARS-CoV-2, are currently in progress.
HOCl was discovered in 1834, but it has only recently been technically possible to create a soluBon that is pure enough to be commercially viable. Orawize has a shelf life of over 12 months importantly this is not reduced even if the boale is opened and some of the soluBon is used.

The two major benefits of hypochlorous acid are its potent antimicrobial actvity and the fact that it is harmless to host Bssue.

The acBve ingredient id OraWize+ has been described as the “ideal wound care agent” (7). It has been shown to speed wound healing in abdominal surgery (8) breast implant surgery (9) and in the management of leg ulcers and burns. (10)

To further demonstrate its safety, Avenova, a product with the same formulaBon as Orawize+ is licensed for use as an eye wash by the US FDA.

OraWize+ is a completely natural biocide and it is broken down by the body to saltwater. It therefore poses no risk following ingesBon, inhalaBon or accidental eye contact.

There are no known reports of allergy to OraWize.
It is safe for use in pregnancy and breast feeding.
There are no known drug interacBons.

Orawize has professional and home applications as a:

1. Pre-treatment oxidising mouthwash:
Hypochlorous acid provides a safe, and effecBve, method of reducing oral bacterial and viral load prior to dental treatment. Studies from the Wuhan region advise using an oxidising mouthwash prior to treatment as a method of reducing the oral virus count and increasing the safety of aerosol generaBng procedures. (11). OraWize+ is a powerful oxidising agent.

2. As an irrigant during treatment:
OraWize+ has uses in periodontal, treatment where its anBbacterial acBvity is equivalent to Chlorhexidine. (12). Chlorhexidine however is not acBve against viruses so would be unsuitable as a pre-treatment rinse.
In endodonBcs it has been shown to have the same anBbacterial effect as Sodium hypochlorite (bleach) but far, far safer. (13)
Studies show that HOCl can remove biofilm from Btanium surfaces so OraWize+ also has applicaBons in the placement of implants and the management of peri-implant disease. (14)

3. Post treatment and at home.
OraWize+ is effecBve against all of the common oral pathogens.
It can be used to help oral hygiene measures aier treatment such as tooth extracBon. As it has a neutral PH and is free from alcohol, parabens, preservaBves and arBficial sweeteners, it can be used daily as part of a comprehensive oral hygiene rouBne. It can also be used to clean orthodonBc appliances, aligners or dentures.
OraWize+ provides a safe, effecBve oxidising mouthwash that can improve safety for paBents and the dental team, as well as helping paBents manage their oral hygiene.
