What are these yellow/orange spots on my teeth? (photo)

visit dentist and get scaling done. i feel its due to your habit of smoking and coffee. it will go simply by the scaling. u have smoking habit so go for teeth whitening after scaling.

Hi there!  I saw your pictures of your teeth and stains near the gum line.  I am not sure why your dentist did not discuss this with your further. Tooth stains are caused by certain habits and medical conditions.  You are doing your job with the brushing and flossing. The problem would not occur unless there was plaque build up on your teeth in these areas. So the cleaning is not sufficient to remove the plaque from your teeth. Also you mentioned that you smoke and drink coffee which is huge factor in staining and discoloration of your teeth no matter how healthy your teeth. Maybe you need to see a hygienist every three months or a dentist who can do deep cleanings on your teeth to remove the heavy plaque. Also make sure you are brushing and flossing properly. You can try whitening after the plaque is removed and there is no visible decay.  You also suffer from chronic sinus infections which may contribute more bacteria in your saliva. You need NOT smoke or smoke less and drink coffee through a straw!  Sounds like not a lot of fun, but these culprits cause heavy staining to the enamel of your teeth!

It appears that yes the spots are from weakened enamel--this is from calcium leaching from the enamel--what we call early decay--it is best to remove the discolored areas and place tooth colored composites--have your dentist use a microfill composite that will hold its polish and reduce restaining--Good luck Dr John Merrill
