British scientists have developed an innovative dental gel that could potentially repair damaged tooth surfaces and reduce the need for traditional dental fillings.
Dental cavities are among the most common oral health problems worldwide. Currently, dentists treat cavities by removing damaged tooth tissue and filling the resulting holes with dental materials. However, the procedure can also affect healthy tissue and cause discomfort for patients.
A new development by British researchers could offer an alternative approach by helping damaged tooth surfaces regenerate.
According to research published in the journal Nature Communications, the newly developed gel is based on a protein called amelogenin, which plays an important role in the development of tooth enamel in young children.
Researchers explained that the gel can fill small holes and cracks in teeth while encouraging the formation of new mineral crystals using calcium and phosphorus.
The gel creates a thin but durable protective layer on the tooth surface, which can remain in place for several weeks. Its durability, however, may depend on individual habits.
Unlike bones and other body tissues, tooth enamel does not naturally regenerate once it has been lost. Although certain toothpastes and chemical treatments can provide temporary protection, dental fillings remain a commonly used treatment for cavities.
The researchers said the new gel could help restore tooth surfaces, including those that have suffered considerable damage.
However, the availability of commercial products based on this technology remains uncertain, and further development will be needed before they become accessible to the public.
If successfully developed for wider use, the technology could represent an important step towards less invasive dental treatments.
