What causes tooth sensitivity after fixing crowns?
Dental Crowns are the prosthetic devices with which a trimmed, drilled or broken tooth is covered to restore its appearance and strength. Root Canal Treatment (RCT) is also completed by capping the hole made in the treated tooth. Similar to dental implants and bridges, teeth crowns are also used as a methodology to restore a missing tooth.
When a tooth is wrapped with dental crowns, mild pain and sensitivity occur for some days. Later it subsides within 1-2 weeks. If such sensitivity in a crown fitted tooth becomes intense or prolonged for many months, then the treated tooth will be at risk.
In this post, Dr. Gopi Krishna the reputed Dentist in Chennai has revealed the underlying causes of crown sensitivity.
1) Crown detachment
When the crown becomes loose, it begins to isolate from the abutment tooth. In such cases, the soft inner regions of the abutment tooth are exposed and cause sensitivity.
It occurs when the adhesive material begins to leak or the crowned tooth encountered a hard bite. If the detached crown is not treated at a time, it will lead to the dissolution of the cementing agent and higher are the chances for decay in the abutment tooth.
2) Disturbed Nerve
In certain cases, the filling materials used under the dental crown irritate the nerve tissues present inside the tooth. It will trigger the abutment tooth o cause sensitivity. Endodontic treatment is the right thing to treat this issue.
Few people encounter this discomfort even after removing the infected nerves with Root Canal Therapy (RCT). It is because of the existence of the nerve endings present in the dentin layer. A Root Canal Specialist takes care of the problem.
3) Porcelain crown damage
The dental crowns made up of porcelain or ceramic are also vulnerable to damage. When you bite a hard eatable or sturdy particle with the crown fitted tooth, it will chip or break the tooth cap. It is easy to repair minor cracks. In contrast, replacing the crown is mandatory if the damage is huge.
When your crown gets damaged, visit your Dentist immediately as soon as possible. If the treatment gets delayed, the crack becomes expanded and leads to serious infection.
4) Cavity in the abutment tooth
Dental caries in the natural tooth under the teeth cap is also possible. It occurs in the cavity filled crowned tooth. If the dental caries is not extracted properly, the remaining cavities will propagate beneath the crown. It ends in teeth cavity. Then the crown has to be removed and the treatment should be done once again to preserve the tooth.
5) Gum Diseases
In order to fix crowns over a tooth, a small portion of the gums around the tooth should be removed. Because of this, some people suffer from receding gums. When the gums recede, it exposes the deeper regions like the tooth root. This will lead to tooth sensitivity.
Gum recession and other gum diseases like Gingivitis will happen if you do not maintain proper dental hygiene after fitting crown.
6) Cracked Root
Apart from damaging the crowns, a hard bit is powerful to cause a crack in the tooth root. Unlike repairing a decayed tooth, it is hard to treat a tooth which has cracked root. In this case, tooth extraction is the only solution to get rid of crown sensitivity.
Conclusion
Whether it is fixing crown after Root Canal Treatment or crown is fixed to replace a missing tooth, you should take care of it like your natural teeth with effective oral hygiene routine and by following the aftercare tips suggested by your Dentist.
It will help you to extend the lifetime of the crown you got and avert the discomforts like pain and sensitivity in the crowned tooth.
