Scientists Develop New Technique for Regenerating Tooth Enamel

Tooth enamel is the protective coating on the crowns of our teeth. It acts as a barrier and helps protect the inner structures of our teeth from decay, chips, and fractures. With time, tooth enamel can become worn down due to aging, brushing too hard or using abrasive products, and acidic foods and drinks. Unfortunately, it can be difficult to replace or regenerate lost enamel.

But a new technique recently developed by scientists is providing us with a glimmer of hope. With the help of bioactive nanohydroxyapatite (nanoHA), a biocompatible material, scientists are now able to regrow tooth enamel. They discovered that nanoHA has properties similar to those of mammalian hard tissues, such as bone and teeth. They also discovered that when it is coated with a polyvinyl siloxane (PVS), nano HA not only adheres to the tooth surface but also promotes the production of amelogenin, a protein responsible for the growth of enamel.

In this article, we’ll discuss the details of this technique, the potential it has to make a difference, and some other treatments that may be used to restore damaged enamel.

What Is NanoHA?

NanoHA is a synthetic material created using nanotechnology. It is made out of a combination of naturally occurring minerals, including calcium and phosphate, (the same minerals found in our teeth) and an organic polymer. This material has similar properties to that of the enamel coating on teeth, and it has been found to be non-toxic, biocompatible, and durable.

NanoHA Is a Ray of Hope for Enamel Renewal

Scientists have discovered that when nanoHA is coated with PVS, it’s able to bond to the surface of the tooth and allow for the regeneration of enamel. In laboratory tests, it was found to form a thin layer of mineralized enamel with excellent adhesive strength. It also increased the levels of amelogenin, a protein that plays an important role in the formation of enamel.

This new technique is exciting news for anyone who has suffered from enamel decay or damage. Thanks to nanoHA and PVS, teeth may one day be able to regenerate themselves with the help of a simple visit to the dentist.

How NanoHA Is Applied and How It Works

The nanoHA and PVS combination is applied directly to the tooth’s surface. The PVS acts as a bonding agent and helps the nanoHA to remain on the surface. It also helps to promote the production of amelogenin, which facilitates the formation of the enamel matrix.

Once the nanoHA and PVS are in place, it takes about one to two weeks for the enamel to regrow. In laboratory studies, the thickness of the regenerated enamel ranged between 3 and 5 microns, which is considered to be a significant improvement.

Other Potential Treatments for Damaged Enamel

NanoHA is not the only treatment available for restoring enamel. There are other ways to heal damaged tooth enamel, such as:

  1. Baking Soda: Baking soda is a mild abrasive that can help to remove plaque and bacteria from the surface of the teeth. It can also help to remineralize. enamel and strengthen teeth.

  2. Dental Resins and Veneers: Dental resins and veneers are another popular treatment for enamel restoration. By attaching a dental resin or veneer directly to the teeth, the appearance of damaged enamel can be restored.

  3. Professional Teeth Whitening: Professional teeth whitening is another effective way to enhance the appearance of worn-out enamel. This procedure works by bleaching the enamel and removing any surface stains.

  4. Fluoride Treatments: Fluoride treatments are often used to treat enamel damage caused by acid erosion. The fluoride helps to remineralize the enamel, making it more resistant to acid attack.

NanoHA and PVS is a promising new technique that has the potential to revolutionize the way dentists treat enamel decay and damage. While it still needs further testing, the results so far have been encouraging. Along with nanoHA, there are other treatments available for restoring damaged enamel that can be used in combination to improve the appearance and strength of the teeth. When used together, these treatments can be highly effective in restoring the health and beauty of your smile.
