Why do you want to make a crown after root canal treatment?

Root canal therapy is usually called nerve pump. Why do you need a crown after root canal therapy? There are three reasons:

1, because the teeth that need root canal treatment are generally very decayed, although root canal treatment has been completed at this time, the remaining tooth tissues are very fragile, easy to break and crack, and lose their normal functions, so it is impossible to restore their functions simply by using materials.

2. Root canal therapy is to remove and disinfect the residues and bacteria in the root canal as much as possible with drugs and instruments. However, if this disinfection process is to be carried out seriously, many teeth infected by bacteria and tooth tissues that must be corrected must be removed. Therefore, once root canal therapy is performed, most teeth may not be able to support chewing force enough and may break. There is no way to restore their functions simply by using materials, even if they can restore long-term effects.

3. After root canal treatment, teeth lose the nutrition supply of pulp, just like trees without roots, they slowly wither and become very fragile, which leads to the increase of tooth brittleness and easy splitting.

These are the reasons for making a crown. Because the supporting force of teeth is obviously weakened after root canal treatment, it may not be enough to support chewing pressure under certain conditions, and it is easy to split the crown, so it is necessary to make the crown in time to protect the teeth.
