Magnesium oxide, an inorganic salt white powder, is widely used due to its excellent properties in different fields. Especially in dental materials, the application of magnesium oxide has significant practical effects.

Firstly, the emergence of magnesium oxide based toothpaste has brought revolutionary changes to oral health care. This new type of toothpaste is mainly composed of magnesium oxide powder, which is combined with water through a fine mixing process to form a unique toothpaste texture. Compared with traditional toothpaste, magnesium oxide based toothpaste exhibits higher antibacterial and anti-inflammatory effects. It can penetrate deep into the surface of teeth, effectively remove bacteria and food residue, significantly reduce the formation of dental plaque, and help alleviate oral inflammation such as gingivitis, providing comprehensive protection for oral health.

Secondly, significant achievements have been made in the application of magnesium oxide in dental filling materials. Magnesium oxide based composite materials are an ideal choice for repairing dental caries, wear, and cracks due to their excellent biocompatibility and mechanical properties. This material not only has good compatibility with tooth tissue, but also has high hardness and wear resistance, which can maintain the shape and function of teeth for a long time.

In addition, magnesium oxide is also one of the ingredients in teeth whitening agents, bringing good news to people who pursue beautiful smiles. It can neutralize acidic substances on the surface of teeth, effectively reduce pigment deposition, and restore natural whiteness of teeth.

It is worth mentioning that magnesium oxide has also shown great potential in the field of dental implants. Research has shown that combining magnesium oxide with bioactive glass can significantly improve the biocompatibility and osseointegration ability of implants. This discovery provides new ideas for the development of dental implant technology, which is expected to bring more natural and stable restoration effects to patients with missing teeth.

In summary, the application of magnesium oxide in dental materials has broad prospects and enormous potential. However, in order to ensure its safety and effectiveness, we still need to conduct more in-depth research and clinical validation. I believe that with the advancement of technology and the deepening of research, magnesium oxide will play a more important role in the field of dentistry and make greater contributions to human oral health.
