Dear Sir, good day I am 29 years old undergone a treatment, for one of the upper jaw front teeth (Incisor) for tip of teeth broken. For that teeth carried out root canal treatment and crown placed. After that treatment, after a week days that teeth sensitivity was increased. Please note followed proper hygiene and brushing techniques, no symptoms were there - swollen, puffy, bleeding, or bad breath. Felt a painful sensation in teeth while taking hot or cold beverages or food. Look healthy and normal other than sensitivity. Before the treatment not having any sensitivity issue. Please suggest, the temporary and permanent solution for this issue. Thanks,
