Sensitive teeth: There are reason for having sensitive teeth.Your dentist will find the cause and can treat better. Sensitive teeth could be due to wearing away of enamel by use of hard brush , more pressure and wrong brushing technique , sensitivity may be due to chipped or broken teeth , cavity , night grinding habit.Treatment depends upon the cause.

Cause determines: There are many reasons that teeth can be sensitive, namely cavities, erosions, abrasions, abfractions, broken or marginally defective fillings, deep and big amalgam fillings, bruxism, gum recession, etc. The cause of the senstivity should determine the best way to reduce or eliminate it. Find out what´s causing it and then ask your dentist the best way to alleviate it.

Depends: Depends on what they are sensitive too and what habits you have if any. Issues that can cause sensitivity is recession, grinding of teeth, cavities, gum disease and the list goes on. See your dentist asap.

No quick fix: From a durability stand point there is no quick fix. From a sensitivity stand point there are desensitizing toothpastes. If you want durability i would first look at the condition of your teeth. Do you grind your teeth? Did you have braces? How is your occlusion? Do you have periodontal issues? I have more questions but limited here. A treatment plan would be next.
