Scientists find a simple way to stop cavities without drilling

Scientists have discovered a simple method to prevent cavities without drilling, using a liquid called silver diamine fluoride. This treatment can be applied in seconds and has been shown to stop decay in over half of treated baby teeth in a major US trial. The method is pain-free, requiring no shots or sedation, making it ideal for young children. However, it does have the side effect of permanently darkening the decayed area where it is applied.
