Hi. .If the sensitivity persists after the use of a desensiting paste for one month then you need to get it checked with X ray investigation. . It could probably due to deep caries or cavity ..
If the sensitivity is due to a cavity, a restoration can be placed. If gum disease is the cause, the dental professional can perform a thorough cleaning of the area.
However, if the cause is from dentin being exposed, then there are a number of professional and at home treatments that can be used to reduce the sensitivity.
In Office Procedures:
Fluoride varnish can be applied to exposed areas, strengthening the enamel and dentin
Fluoride foam or gel can be placed into a mouth tray; you then sit with this in your mouth for 3-5 minutes, providing the teeth with a high concentration of fluoride to strengthen the areas
Bonding agent, the material used to stick tooth colored restorations to teeth, can be used to seal the dentin surface and provide a barrier to the stimuli that cause sensitivity
Use a very soft bristle tooth brush, with low abrasive tooth paste
Brush correctly and do not over brush
Use a tooth paste specially formulated to soothe the nerve endings in the tooth
Use a high concentration fluoride toothpaste (given to you by the dental professional) to strengthen the tooth surface
There are a number of treatments available, and your dental professional can help you find those that will work best, depending on your situation. Always seek a dental professional's help â do not try to diagnose this problem yourself. It may be the sign of something more serious, and only a dental professional can tell you what it really is.
