Since Getting Veneers on my Front Teeth Due to Calcium Marks, Been Getting Brown Stains on the Area Around the Veneer? (photo)

These bonded veneers are leaking.  You should talk to your dentist about replacing them.  With a good bonding technique, marginal leakage in this part of the tooth is rare.  You may be able to remove the veneer and the calcium spots without replacement of the composite veneer if the calcium spots are very superficial.

From your photos you do not have porcelain veneers which do not stain.  Looks like you had direct bonding or if it was made at the lab some sort of composite restoration.  What is staining is the junction between the composite and the tooth.  Your dentist should be able to polish off the staining but due to the material and technique used it will reoccur.

From the picture it looks like you had chairside composite veneer done which is covering about half of your tooth. Doing this kind of restoration can be technique sensitive and if it is not idealy polished composte surface tends to adsorb pigments and that is why you can notice darkening. This kind of problem could be avoided if you would get a porcelain full surface veneer. However if you would choose to continue with composite veneer, you will need it to be re-done.

To completely remove calcium spot is not an easy task because it sometimmes go deep and that would require removal of significant amount of tooth structure, which could lead to a weakening of the tooth structure. Your dentist should give a recommendation on how to solve this problem. Good luck!
