Hello ...d symptoms ur telling is of deep caries...get an x-ray done..so dat treatment can be started..d affected tooth can be saved with root canal treatment...plz visit nearby dentist for evaluation and meds

Going on the by the description that you have mentioned and without a look at the clinical condition of the teeth, the only suggestion that we can give at this point is to go for a proper clinical checkup so that the causes of your discomfort can be ascertained. It seems that you have cavities in more than 1 teeth which will require treatment depending upon the extent of the decay. Delaying the treatment should be avoided as it can cause the symptoms to aggravate further. Regards.
