IMU University Research Explores New ‘Smart Dental Materials’ Could Make Fillings Last Longer and Prevent Tooth Decay

A groundbreaking dental research project at IMU University is exploring the use of smart bioactive dental materials enhanced with carbon quantum dots to improve the treatment of tooth decay. Led by A/Prof Dr Umer Daood, the research focuses on next-generation restorative dentistry solutions that can fight bacteria, strengthen tooth structure, and support natural healing processes.

• Research led by A/Prof Dr Umer Daood on developing smart dental materials for tooth decay treatment
• The materials used are carbon quantum dots with antibacterial and regenerative properties
• The technology aims to reduce failed dental fillings and recurrent tooth decay
• Early studies show promising improvements in material strength and decay resistance

A new breakthrough in dental research could soon change the way we treat tooth decay, with scientists developing “smart” materials that not only repair teeth but also help protect and heal them over time.

A/Prof Dr Umer Daood, Head of Restorative Dentistry from the IMU University’s School of Dentistry, a researcher in dental materials and biomedical science, is leading work on next-generation dental technologies designed to overcome a common problem faced by millions of patients worldwide: dental fillings that fail over time.

Currently, many dental restorations need to be replaced after a few years, not just because they crack, but because bacteria return and cause new decay around the filling. This often leads to repeated dental procedures, gradually weakening the tooth and increasing treatment costs.

Dr Daood’s research aims to break this cycle.

His team is developing advanced materials enhanced with tiny carbon-based particles, known as carbon quantum dots. These materials are designed to do more than just fill cavities. They can potentially fight bacteria, strengthen the tooth structure, and help rebuild lost minerals.

“In the future, dental materials should not just repair damage, but actively protect and support the tooth,” the research suggests.

“It is time for quantum changes and overhauling of our tooth biology, it is our first discovery” he added.

While traditional dental research looks at how materials behave on a visible level, Dr Daood looks at the molecular and electronic level. By understanding how tiny particles interact with living cells and bacteria (quantum biology), he can design materials that are more precise and effective at stopping infections before they start. These materials communicate and dispel the very notion of tooth decay.

Unlike conventional materials that focus mainly on strength, this new approach targets the root causes of failure; bacterial growth and weakening of the tooth over time. The goal is to create longer-lasting treatments that reduce the need for repeated dental work.

The technology has already shown promising results in laboratory studies, demonstrating improved strength and better resistance to decay. However, further testing is needed before it can be used in clinical settings.

Experts say that if successfully developed, such innovations could significantly:
Improve oral health outcomes,

• Reduce healthcare costs, and
• Enhance patients’ quality of life.

Dr Daood does not just want to keep his discoveries in a lab; his focus is on Translational Innovation. This means taking a new scientific discovery and turning it into a real product—like a better dental glue or a new type of filling—that a dentist can actually use on a patient.

While still in its early stages, this research signals a shift toward a new generation of “bioactive” dental care—where treatments do not just fix problems but help prevent them from returning.

He says, “They are here; quantum biomaterials will be a quantum leap in dental healing”.
