Painful symptoms arising from exposed dentine are common in the adult population. Sensitive teeth or dentine sensitivity (hypersensitivity) is characterized by pain, elicited by various stimuli, that disappears when the stimulus is removed. Some people are sensitive to cold alone, others to touch, sweet or sour foods or combination of any of these stimuli. Pain may be so severe that they may find eating difficulty. Continue reading

Is tooth sensitivity a problem?
Generally tooth sensitivity is not a serious dental problem and is fairly well tolerated by most people. In a subgroup of the population though, sensitive tooth can be severe, to the extent that even a gentle blow of air on those surfaces can be very uncomfortable and unbearable.
Tooth sensitivity is not uncommon and most people would have experienced it at some point of their lives. But usually our saliva, which by nature is filled with minerals; act as a protective mechanism by sealing the area of exposed dentine. This is done through laying down of mineral deposits over a period of time, which explains the reason behind sensitive tooth needing a couple of days before it settles down. Professional scale clean can inevitably remove this soft layer, allowing dentine to be exposed again, resulting to tooth sensitivity. But this does not usually cause a problem as normal saliva will recreate the seal in a matter of days, sometimes hours. Continue reading
Tooth sensitivity is a common dental condition where the teeth becomes extremely sensitive to hot and cold, leading to tooth pain. It affects quite a number of adults, sometimes affecting their lifestyle where certain food with extreme temperatures such as ice-cream or hot coffee needs to be taken cautiously or in some cases, avoided completely.
Cause of tooth sensitivity
Tooth sensitivity occurs due to the exposure of dentinal tubules layer of the teeth which is usually protected by enamel. There are a range of factors that can contribute to dentine exposure, such as tooth grinding, broken tooth, tooth erosion, defective tooth filling, tooth whitening, tooth straightening, dental crown or bridge work and so forth. These are explained as followed: Continue reading
