What effect will root canal treatment have on the tooth?
1. The tooth loses its pulp
The role of the pulp in the tooth is mainly as follows:
1. Restorative function: the production of restorative dentin when the pulp is stimulated;
2. Defensive or protective function: the pulp has a certain restorative function;
3. Inductive function: inducing enamel formation by enamel-forming cells;
4. Resorption function: resorption of the roots of milk teeth to guide the eruption of permanent teeth;
5. Nutritive function: supplying nutrients to the dentin;
6. Formation function: formation of secondary dentin throughout the life of the pulp;
When the tooth is cleared of pulp, all of the above functions are zeroed out.
The tooth no longer has new dentin formation and no more proprioception.
2. Reduced resistance of the tooth
Due to the possibility of destruction of the marginal ridge due to pulpotomy, extensive chipping due to caries, thinning of the root canal wall due to root canal preparation, the tooth is no longer able to resist the force.
This means that one day, at some point, the tooth will crack when it bites something, and how desperate it will feel to have the tooth extracted before the work is done.
3. Tooth discolouration
The original decay has not been removed or pigmented, the pulp remains have not been removed, the root canal has been sealed with calcium hydroxide for too long.
Purpose of crown restoration
3.1 Tight crown sealing
The tooth has been in a humid and complex environment in the mouth for a long time, so it is important not to ignore the end of the tooth!
3.2 Increasing the tooth's resistance
Put an armour on the tooth!
Don't skip the necessary crown restorations!!!
