Many people suffer from sensitive teeth. In fact it is probably the #1 problem expressed by patients , especially as they age. Teeth are sensitive for many reasons and there are different types of sensitivity. Patients report: sensitivity due to sweets, sensitivity to cold , sensitivity to hot, intermittent sensitivity to chewing, general acheness in the upper jaw and pressure sensitivity to a particular tooth.
The most common complaint by far is sensitivity to cold and it can be caused by a cracked tooth or a cracked or defective filling. Sensitivity to sweets usually means that somewhere there is dentin that is not properly covered. bacteria in the area are exposed to the sweets and multiply and create acid which causes pain in the tooth.
Sinus problems can mimic tooth problems by creating sensitive upper teeth. However if your lower teeth are sensitive you can be certain that it is not due to sinus inflammation.
