First, as you are probably aware, the fizzy pop is terrible for your teeth. The black staining between your teeth could be tooth decay
caused from the pop. This is very typical of a heavy soda drinker. In regards to your agoraphobia
, you need to see a dentist
that uses sedation. Either pills you take before your appointment or in cases where patients are extremely nervous, IV sedation. However, I recommend you see a dentist sooner than later. Tooth decay is progressive and more involved and difficult procedure are often necessary if you wait too long. As for now, try to keep your mouth clean by brushing 2-3x per day. And FLOSS! Flossing is very important for those areas between your teeth.
