New Gel Can Regrow Tooth Enamel and Prevent Decay

Topic: Health

Scientists at the University of Nottingham have developed a new dental gel that can rebuild damaged tooth enamel. The gel works by imitating the natural process of enamel formation, using proteins to guide the growth of new mineral crystals. This could potentially prevent decay and restore worn teeth.

A team of scientists at the University of Nottingham's School of Pharmacy and Department of Chemical and Environmental Engineering has created a new dental gel that can rebuild damaged tooth enamel. The material is designed to imitate the natural process of enamel formation, which occurs during infancy. It contains proteins that guide the growth of new mineral crystals, helping to repair weakened or eroded enamel and even protect teeth from future damage.

The gel works by forming a thin but durable coating on the tooth's surface, filling in small cracks and pores, and acting as a framework for rebuilding the mineral structure of enamel. This process is called epitaxial mineralization, where new crystals grow in alignment with the existing structure of the tooth. The researchers claim that this organized growth helps the repaired surface recover both its microscopic architecture and physical properties.

The team has also found that their material can help people with exposed dentine, which is the softer layer beneath enamel. When applied to exposed dentine, the gel can grow an enamel-like mineral layer over the surface, reducing tooth sensitivity and creating a stronger surface for dental restorations to bond to.

Why It Matters

This breakthrough could have significant implications for oral health in India, where poor oral hygiene is a major concern. Tooth decay affects almost 50% of the global population, leading to pain, infection, and tooth loss. If this gel becomes widely available, it could help prevent these problems and improve overall health.

Epitaxial mineralization

A process where new crystals grow in alignment with the existing structure of the tooth.

Dentine

The softer layer beneath enamel, which can become exposed when enamel wears away or gums recede.

Enamel erosion

Weakening or loss of tooth enamel due to acid attack or other factors.
