Company profile

Koite Health was established in 2018 in Espoo, Finland and is a fast growing medical technology company.

The company was founded to respond to the growing need for new treatment solutions against dental bacterial infections.

PROBLEM: 95% of oral diseases are caused by harmful bacteria in dental plaque, a sticky film of bacteria that constantly forms on teeth. Unfortunately, daily brushing and flossing only remove about 50-65 % of dental plaque, which results in 80% of adults suffering from some level of gum disease at some point in their lives. The total cost to society is estimated at $470bn annually.

SOLUTION: Koite Health has developed and commercially launched Lumoral, which kills 99.99% of the harmful bacteria in the mouth.  The entire Lumoral treatment process can be done at home and takes less than 15 minutes.

Since the market entry in 2020, more than 10,000 Lumorals have been sold and Koite Health has doubled its revenues every year. The technology is patented and is based on strong scientific evidence and support.

Koite Health is now growing globally in the €31bn home dental care market and has this spring signed distribution and partnership agreements with the leading companies in Germany, Italy, UK and Denmark. Negotiations are also underway with France, Poland, and Portugal, and even the FDA process for entry into the US was initiated last year.


Lumoral is a revolutionary dental treatment method that is easy to use and brings professional level antibacterial treatment to your own home.  

The Lumoral treatment consists of two parts: Lumorinse mouth rinse (1 minute), followed by Lumoral mouth applicator (10 minutes). The whole treament is completely painless and can be done at home in less than 15 minutes. Afterwards you should brush your teeth carefully. Recommended use is twice a week for preventive treatment and daily use for medical treatment, for the period recommeded by your dental professional.


Lumoral is based on a patented combination of antibacterial blue light (aBL) and photodynamic therapy (aPDT).  In the process with aBL and aPDT, light activation causes the local release of heat and/or reactive oxygen, resulting in the inactivation of harmful bacteria. In aPDT an external photosensitizer and in the aBL bacteria internal molecules are activated.

Lumoral's dual-light method greatly enhances the antibacterial power of the treatment by providing bacteria external and internal antibacterial action simultaneously.

Lumoral is available through dentists, pharmacies and the webshop.

Lumoral has been registered as a medical device in the EU, UK and in Switzerland. 

Business model

Koite Health focuses on product development and the production of clinical proof for new treatment areas for the Lumoral method. Koite also handles the marketing and distribution of Lumoral products in our home markets Finland and Sweden. Products are marketed and promoted through dental professionals and directly to consumers. 


Outside Finland and Sweden, Lumoral will be marketed and distributed by local distribution partners, which already have existing workforce and networks to distribute oral care products to dental professionals and consumers. These carefully selected partners sign exclusive agreements on their market(s) and bear all the costs for the launch and promotions. All manufacturing has been outsourced. 


At each new market, Lumoral is first marketed and promoted through dental professionals and the scientific community/key opinion leaders. At a later stage there will also be some level of consumer marketing and campaigns. 


Koite Health earns revenues on the sales of Lumoral start-packages and recurring revenues on the sale of Lumorinse tablets, needed in the treatment. More information about the business model and the recurring revenue can be found in the Information Memorandum, included in the Documents section. 


Total cost of bacteria-related dental diseases is estimated to be $544b, of which $356b is direct and $187b is indirect costs. Periodontitis costs $54b in direct treatment costs and an additional $25b in indirect costs.

There is nothing similar to Lumoral on the market. Lumoral treatment vastly outperforms all current methods in terms of treatment efficiency, usability and cost-effectiveness.   

  • 80% of adult population has prevalence of gingivitis.
  • 50% of over 30 year old adults have some form of periodontal disease.
  • >20m dental implants placed per year and 20% of patients face some level of infection complications.
  • +1000m people suffer from severe gum disease (periodontitis).
  • > €8.4b addressable market for Lumoral in prevention and treatment of severe periodontal and peri-implant diseases.

  • Monthly sales have increased 4-5-fold since last year
  • Lumoral is now been recommended by the Finnish Dental Hygienist Association 
  • 3 clinical studies on the use of Lumoral have been completed and published, and there are a dozen ongoing and planned studies 
  • Lumoral's monthly subscription model has been a great success and more than 85% of those who joined last year are still subscribers 12 months later 
  • New international cooperation and distribution agreements have been signed for the markets of Germany, Italy, Denmark, and Great Britain, and negotiations are ongoing for France, Poland, and Portugal, for example. 
  • Foreign partnerships have gotten off to a great start, and the international academic/university interest in Lumoral has also been a very positive surprise.

In this round, we are looking for a pre-money valuation of €20,003,249.88.

More detailed information on the valuation of the company can be found in the information memorandum.

Exit scenarios

Icon 1

Trade sale: Large international medical technology and healthcare companies are constantly looking for new innovations and innovative companies, and within the medical technology sector this is probably the most common path for exits. There are several global billion dollar companies within dental sector, especially within the dental implant segment. Koite Health has already had discussions with some global companies about a possible cooperation and about including Lumoral in their product offerings.

Icon 2

IPO: A possible listing on the Helsinki Stock Exchange when the company has reached a sufficient size and profitability (from 2026 onwards).

Icon 3

Private equity/Venture funds: Another exit path and buyer candidate group could be the specialized dental sector investment funds. Within the dental segment, those investment companies are mostly located in the USA, and we have already had discussions with 3 of them. The main focus of the US-based investment funds is on the US dental markets and the funds and the progress of our US plans and especially the FDA application are a key factor.

Q&A - Koite Health's answers to investors' questions

1. Does Lumoral or the mouth rinse Lumorinse attack tooth enamel or does it rather strengthen it?

Lumoral mouth rinse does not attack or damage the enamel. Lumoral protects the enamel by removing acid-producing bacteria from the surface of the enamel. Acid-producing bacteria are the main contributors of tooth decay which is why Lumoral is so good for in preventing tooth decay development.


2. What are the ingredients of the Lumorinse mouth rinse? Does it contain fluoride?

Mannitol, xylitol, ascorbic acid, sodium bicarbonate, polyvidone, indocyanine green, magnesium stearate, silicon dioxide, peppermint aroma. The key ingredient is the Indocyanine green which a harmless color used widely in medical diagnostics and treatments.

3. How are sales currently distributed among the different countries?

In the first 8 months of 2023, Finland and Sweden accounted for 81.5% of Lumoral sales. The new markets and distribution agreements which were signed in during the spring (Germany, Italy, UK, Denmark) are now starting to kick in and in August the European sales accounted already for 32% of sales.


4. On there is talk of whitening - is this like bleaching or in any way harmful to teeth, enamel etc.? If not, why or what would be the difference to whitening by bleaching?

Lumoral's whitening effect is based on removing staining and coloring from the surface of the teeth. This is based on the enhanced removal of dental plaque (bacteria) from the surface of the teeth. This effect is beneficial for teeth, enamel and gums.


5. Are Lumoral's patents such that competitors cannot produce a similar product?

Lumoral is protected by several patents. Two patents protect the Lumoral product and method itself, two other patents protect the future development solutions of the Lumoral device, and two other patents protect the expansion of Lumoral technology to new indications of use, such as the treatment of skin bacterial infections.
