Internal Bleaching Pain

User Level:
Patient
Posted by: inquiringPt  (4 years ago)
Good evening,

I hope someone will be available to answer my questions regard PAIN FROM INTERNAL BLEACHING. This is for a front tooth which had a root canal nearly 8 years ago and has discolored. My dentist recommended internal bleaching to have it match my other teeth and I agreed. I questioned if there would be pain and my dentist told me no, there should not be any pain because it is a dead tooth and therefore has no nerves.
The bleaching took place less than 8 hours ago and the procedure did not hurt.
I have not exposed the treated to any extreme heat or cold.
I have not attempted to eat or bite anything tough that may agitate the site of bleaching.
On a pain scale of 1(no paid) to 10(worst ever), this is an ongoing 4.
About 6 hours ago there was an EXTREME (Maybe 7?) burst of pain at the effected area that lasted a few seconds and has subsided to a level 4 and has not changed since.

I'm concerned about brushing my teeth tonight because of the pain and it is a Saturday night; so I do not suppose my dentist will be available until Monday.

Please advise!

Never had that happen. I guess it is possible that some bleach soaked through tubules in the root, and irritated the periodontal ligament. Was heat applied to the tooth? That might explain ligamental irritation. Also, some bleach may have leaked past the rubber dam, and the pain is coming from the gums that were burned by the bleach.

More and more, I am using tray bleaching for root canal teeth with lower bleach concentrations. is is a little gentler.

Dr. Henry,

Thank you so much for getting back to me. The pain was an ongoing 2 for the day and has been settling down to a 1 this evening. There is, what appears to be, a bit of a burn mark on the top of my gums (UR2, I believe that is tooth #7?) which had the procedure done.

If you can please advise, I am being very cautious about eating and hygiene upkeep in regards to that tooth. All I wanted was to make sure my tooth matches the rest of my teeth colorwise. I do not want to risk chipping or breaking my already brittle tooth. My perio is healthy/normal all around and the tooth used to have a lot of composite. My next apt is not until a few weeks. Is there a high or at least higher risk of chipping/breaking my tooth is it's current state.

I can upload an image of the back of my effected tooth and the potential sight where bleach leaked "past the rubber dam".

Thank you again for your response!

Bleaching does not affect tooth strength. I am not sure what you mean when your you say "the tooth used to have a lot of composite." Do you mean the tooth had a big composite before the root canal? If so, you might be better with a post and crown. As you bleach your teeth, the color of the composite will not change, giving a shade mismatch between the composite and the natural enamel

The burned gum will heal fairly quickly.
