Resin: the Most Common Dental Material
“Can’t you just use the mend? “When some parents hear about their children’s small cavities, the doctor even suggests that they should use nerves to make braces, and they will be furious.
“The doctor helped me before! It’s just that he’s gone, can’t you mend it for me? ”
“I’m sorry, I really can’t. ”
“There is a limit to the amount of resin used to fill teeth. ”
Commonly used dental materials
Now the most common dental material is composite resin, which has the advantages of beauty and good repair. If the dentist didn’t give special instructions, most of the materials are used now.
The color of resin is similar to the color of teeth. Compared with the metal color of silver powder, the general public may not easily see that this tooth has been mended with resin. Even if the doctor pays attention to it, it may not be easy for the dentist to see that this tooth has been mended.
And above operability, resin operation is still good operation, normal dentists will fill. But it depends on the doctor’s skill if you can make it up pretty. Just like painting, it’s very easy to draw things. Maybe three-year-old children can draw things, but it’s not easy to draw things beautiful enough to be pleasing to the eyes.
In recent years, with the progress of material science, the strength of resin has been higher than ten years ago. It can be used not only in the place where the bite force of anterior teeth is lighter, but also in the posterior teeth where the bite force is stronger. However, if the scope of the repair is too large (too wide or too deep), the strength of the resin may be insufficient, so it is easy to break or fall off and must be treated again.
In addition, the resin is very afraid of water in the process of filling teeth (after filling, it is not afraid of water). If it comes into contact with water, the property of resin will become poor and easy to have problems. So if it’s easy to have saliva flooded teeth, or when the child’s coordination is low, and the tongue will move randomly to make saliva spray around, the doctor may use tools such as cotton roll or waterproof rubber curtain to prevent the resin from contacting the water, so that the filling quality of the resin will be better.
Moreover, although the resin has just been mended beautifully, it may turn yellow slowly over time. Usually, the change will be in years, very slowly, but it may still happen. If it is in such an important position of aesthetics, discoloration should also be taken into account.
Finally, although the resin itself will not decay, but because it is not integrated with the teeth after all, with the hot rise and cold contraction of the meal and the impact of the usual bite force, a small gap will slowly appear between the resin and the teeth, and this small gap will be easy to decay again, which is also the reason why the teeth may need to be refilled in a period of time.
