Advantages and Disadvantages of Resin Dental Fillings

advantage

Resin is mainly used for front teeth and is called tooth-colored material. The filled teeth are so realistic that it is almost impossible to tell that they have been filled.

shortcoming

There are also resins used to fill back teeth. However, some patients will feel soreness after surgery. At this moment, the doctor is in trouble. 

Pain after filling and being afraid to bite is not always a good thing. What should I do? Remove it! When replacing amalgam, 

the doctor needs to carefully remove it at this time, because the boundary between the resin and the teeth is not clear, and the healthy teeth may be worn away. 

Therefore, for patients who have back teeth filled, I will give them a Explain the advantages and disadvantages of each of the two options and let them choose. 

Most patients choose silver amalgam, and a few beauty lovers choose resin. Then make a good deal: if there is postoperative soreness, gingival amalgam will be replaced.

The second disadvantage of resin fillings for posterior teeth is that it is easy to get stuck after eating, because filling teeth with adjacent caries requires placing a molding piece. After placing the molding piece, it is light-solidified. After hardening, a gap will appear for the molding piece to be placed. It’s easy to get your teeth stuck. Picking your teeth after eating is both indecent and troublesome!

The third disadvantage of resin filling of posterior teeth is that it is easy to form overhangs of the filling. When filling the proximal holes, a molding piece and a gap wedge must be installed. However, no matter how smart the doctor is, he would not dare to say: There will be absolutely no overhangs on the teeth I filled! After removing the molding piece, the light-cured resin has hardened and is the same color as the teeth. It is difficult to find and difficult to remove. Leaving it there for a long time will lead to the destruction of the alveolar bone, which is equivalent to artificial tartar. Friends, do you still dare to choose resin material to fill your back teeth at this moment?

The fourth disadvantage of resin fillings for posterior teeth: microleakage! This is the advantage of resin filling back teeth advertised by resin material manufacturers! But there are unavoidable problems in clinical practice! It is true that resin has a strong bonding force with dental tissue, and the light-cured veneers we made have not fallen off for more than ten years. However, if the moisture isolation is not good, or only moisture comes in, the resin and the The combination of teeth is a question mark! When we remove problematic teeth filled by others, we often find that the resin material is separated from the tooth tissue. No doctor dares to say that there is absolutely no separation of resin from the tooth structure in the teeth he filled with resin.
