If tingling sensation is not going with enafix tooth paste then go for xray to determine the extent of decay.

It sounds like you are suffering from abrasion of the teeth. A common reason for this is the use of an incorrect brushing technique. You can learn the correct technique by watching youtube videos about the same.

There are other treatments available for dentin sensitivity which your dentist can recommend after a clinical evaluation.
