TCD spin-out develops smart solution to teeth grinding

Sensor technology from TCD will be used to record and monitor teeth grinding (bruxism).

A team of researchers, Dr. Padraig McAuliffe and Prof. Brian O’Connell in the Dublin Dental Hospital and Dr. Ramesh Babu and Dr. James Doyle from AMBER, the Science Foundation Ireland funded materials science centre based at Trinity College Dublin, have today (14th April 2015) announced that their new spin‐out company, SelfSense Technologies Ltd has licensed sensor technology from Trinity College, and secured €100,000 investment from NDRC. The company has unveiled a novel intelligent mouth guard device called SmartSplint, which accurately records and monitors teeth grinding (bruxism) of patients and allows their dentists to help them manage the condition more effectively.

SelfSense Technologies Ltd will develop diagnostic and monitoring sensors for tooth‐grinding and SmartSplint will be brought to market in autumn this year by the Trinity College spin‐out company. The company is currently taking part in the NDRC VentureLab programme for scitech start‐up companies.

SelfSense Technologies has secured a licence to technologies developed with over €700,000 in grant funding from Enterprise Ireland, Science Foundation Ireland and the Health Research Board at Trinity College Dublin and the Dublin Dental Hospital. The team is seeking to raise investment in the next 6‐9 months and continues to work in close collaboration with the world class research and clinical facilities at Dental Hospital and the AMBER Centre at Trinity College Dublin. The company arose from collaboration between Dr. Padraig McAuliffe and Prof. Brian O’Connell from the Dublin Dental Hospital and Dr. Ramesh Babu from AMBER and Trinity’s School of Physics and Dr. James Doyle, AMBER.

Tooth grinding or clenching is a very common issue affecting up to half a million Irish people on a daily basis. The nightly grinding of teeth goes far beyond that of a minor inconvenience. This can be a chronic condition, leading to severe facial pain and headaches, dental wear and damage to dental restorations such as crowns, veneers and implants. The cost of repairing teeth damaged by bruxism can run into the thousands or even tens of thousands over time but can be greatly reduced by wearing a night guard (splint). Unfortunately, because bruxism mainly occurs at night, many patients don’t realise that they are grinding. Some don’t use the splints appropriately and the tooth damage and long‐term repair costs continue to mount. SmartSplint will be able to deliver up to date, personalised information about bruxism right to the patient’s phone and help them to understand their condition better and perhaps point to how they could modify their lifestyles to reduce how much they grind.

Dentists understanding and ability to manage the condition will also be greatly improved. Dr. Padraig McAuliffe, co‐founder of SelfSense Technologies, said: “As a dentist, it can be very difficult to know whether an individual patient has bruxism until we see that some damage has been done. By then it’s too late. Early diagnosis and prevention of damage are key. We developed SmartSplint because there were no bruxism tests available that we considered suitable or practical for widespread use at an affordable price. The success of treatment for tooth decay and gum disease were revolutionised by the development of simple tests and we hope that SmartSplint can do the same for bruxism.”

It is expected that SmartSplint will be launched in Ireland late in 2015 and will be available in dental practices internationally in 2016. If you would like more information about the device, when it will be available or feel that you might benefit from it, please contact the team at or visit
