If the cause of sensitivity is decay, then a filling, root canal or crown could be needed. If the cause is receded gums, a gingival graft could be the answer. For general sensitivity to cold, for example, I would start first with a toothpaste like Sensodyne. If that doesn't help, then a dentist applied fluoride desensitizer or resin bonding could be used.

Need to find out the source
Tooth sensitivity can be caused by a number of different factors:
1- Gum recession
2- Undetected decay
3- Grinding or clenching
4- Acidic foods (acid erosion)
5- Thin enamel
I would definitely explore more conservative options first from least to most invasive
1- Perscription tooth paste
2- Topical application of Fluoride
3- A Night guard (if sensitivity is caused by grinding)
4- Flouride trays that you wear 1-2 hours a day
5- Gum grafting
Hope this helps
Find reason for senstivity first
You have to talk to your dentist to find the reason behind sensitivity. Some people might have pronounced sensitivity which can be addressed with office treatments or prescribed toothpastes like Nupro,Prevident, MI paste, Sensodyne etc. Sometimes you need covering of teeth with e.g fillings, crowns etc. If you are experiencing gum recession then you need to talk to your dentist for possible gum specialist referral for possible grafting. Hopefully these suggestions will help you make better decision with your dentist.
