Probably not: It is most likly gingivitus, if you felt some roughness it could be a cavity or tarter build up, the only way to know for sure is to see a dentist and have your teeth xrayed.

I think that I have a cavity on one of my front teeth. I noticed some discoloration . Is there a quick topical OTC fix until i get to dentist ?

Discoloration: Not really. Most chemicals used like bleaching could make the tooth sensitive due to the cavity. It's best to get it fixed.

How can you tell the difference between tarter on the teeth and a cavity?

Easy for Dentist: Tartar or calculus is hard and appears as a deposit on the surface of teeth. It is an almond color but may be stained darker from coffee, tea, smoking, etc especially below the gum surface. Decay is soft and lies at or below the surface of a tooth. Don't try to diagnose these things yourself. See a dentist who is trained for this purpose. Most cavities are not easily visible until a problem!

Yes: Small cavities only get bigger with time. It's better to have them treated sooner rather than later. Patients who wait until they have pain end up with bigger costs, less tooth structure, and more grief.

Cavity: It makes no difference where it is on the tooth. Once the bacteria has eaten away a portion of the tooth, it is called a cavity (dental decay).
