Your problem will get solved with the following treatment 26 needs a rct and a cap 25 cap needs to be cut and removed since there is huge decay under the cap. 24 looks like a small decay that can be restored with a filling Hope this helps

Rct with26 is advised.

If food lodgement is there do flossing and gums massage. If pain persists then go ahead with rct

On viewing your X-ray 26 definitely need pulp testing done for RCT But in any case it requires restoration so that contact is build up between 25& 26 and thr is no lodgement of food and hence no pain. But more problematic is 25, which has a crown, which is inappropriate and hence will lead to food lodgement always because of the space beneath the crown. So you need to get that evaluated.

Depending upon the clinical complains you are making It seems like more of a gum problem becoz of food enlodgement . Do copious rinsing with warm salted water atleast 10 times followed by application of hexi gel 3 times a day There are other clinical pathologies also in the radiograph... Do visit a dentist for a thorough checkup .. Good luck Thanku
