Several possible conditions can cause a metallic taste. The most common is related to not enough brushing and/or flossing. Poor oral hygiene will lead to bleeding gums, and the blood has a high iron content. Other than that some prescription drugs and vitamins can cause such a taste.
Most likely the cause will be either vitamin deficiency or a fractured filling that would be associated with a sensitive tooth but also produce a metallic taste from the separation of the filling itself. It could also be a vitamin deficiency. I would start first with the most likely assuming that you are in good health that you have your dentist investigate the generalized area where you have the most sensitivity which would coincide with a fractured filling.
This may be related to an acid-reflux condition (GERD). Or, if a person has gingivitis or periodontal disease, thus bleeding gums, the metallic taste is attributed to the taste of blood sometimes.
Normally a metallic taste indicates the presence of blood, which is common if you have gum disease. Consult with your dentist to see what may be causing this.
A metallic taste may be the result of something that is being released from your own teeth due to clenching and/or grinding. But it can also be related to a medical issue. You should be seen by either a dental professional or medical doctor to further look into what the source of your metallic taste is coming from.
