Dear friend.

Thanks for sharing your concern.

please explain what do you mean by crackers?is it sweet and sticky in nature?or it is hard nuts you are taking about?

Also, are you sure the patient is having pain in that particular treated tooth only or it is adjacent tooth?

Have you done clinical evaluation like palpation and percussion?and have you checked vitality of that tooth?

A very important finding have you asked about patients nature and duration of pain after eating these crackers?

I am sure these questions will give you your answer.

Hope it helps.

I would be glad to receive further response from you.

thanks.

take care.

Hi,

Thanks for asking the query,

Tooth sensitivity after composite restoration mostly depends upon the cavity depth and the type of dentine bonding agent.
Restoration with shallow or medium depth cavity usually have less sensitivity.

Crackers are sticky substances due to improper bonding between tooth and the restoration creates pressure and sensitivity in the tooth.
There should be presence of protective layer of calcium hydroxide base to give pulpal protection in cases of increased depth of cavities.

I would suggest you to remove the restoration and place zinc oxide eugenol dressing for a week and repeat the procedure by giving a layer of calcium hydroxide.

Hope this helps out.

Regards..

Hello,
Thanks for writing in.
Usually if the composite restoration is carried out successfully,there won't be any pain associated even while eating crackers.
I would suggest you toget an x-ray of the tooth.
Get the infected pulp within the canals removed.
Take complete course of antibiotics too.
Also avoid chewing hard foods with thr restored tooth for minimum of 7 days.
Root canal treatment has to be carried out if there is periapical infection associated.
Take care.
