- A severe toothache, especially when pressure is put on the tooth
- A persistent pimple located on the gums near or below a tooth
- Swollen or tender gums underneath the tooth
- Sensitivity to hot or cold objects, even after the object has been removed
- A discolored tooth
- In extreme cases, the death of the tooth
The filling may break. - In those cases where a tooth's treatment requires more than one appointment, the temporary filling that's used to create a seal to protect your dentist's work might break or come out. If it does, saliva (and the bacteria and debris it contains) will recontaminate the interior of your tooth and your dentist will have to spend your next appointment cleaning out your tooth a second time.
- Even in the case where a tooth's treatment has been completed, if the temporary filling that's been placed looses its seal, coronal leakage may occur. (A situation where bacteria are able to recontaminate the treated tooth's interior.)
The tooth may break. - Since the way their tooth feels is now back to normal, a person is often eager to make use of it again.
- Until your dentist has had a chance to finish rebuilding your tooth, it should be considered fragile. What a disappointment it would be to spend the time, effort, and money to have root canal treatment performed, only to have the tooth irreparably break or crack before it was fully restored.
- Foods to watch out for. - In light of the above, avoid using a root canal tooth to bite into or chew hard or crunchy foods. Notably, this might include items like raw vegetables (carrots, celery) and hard candies. But really, due to a tooth's potentially fragile state, any number of other kinds of foods might be able to cause damage too.
