How To Spot A Cavity

Some of these bacteria feed on sugar entering your mouth and create acids, dissolving the mineral content of your teeth over time. This process is called tooth decay. A cavity may appear as a discolored spot and can be brown, black, or gray on a tooth.

Be on the lookout for issues such as:

 

  • Visible holes in teeth.
  • Tooth sensitivity, especially in the discolored area.
  • Toothache, which may remain constant or radiate to the ear or jaw area.
  • Bad breath or foul taste that doesn’t go away.

  • Tobacco & marijuana products
  • Some Foods – berries, beets, tomato sauce, soy sauce, curries, and chocolate
  • Tetracycline medication

Certain bacteria in your mouth can produce harmful brown or black stains which is an indication that oral health is leading to a decrease in the potential for tooth decay.

How To Whiten Stained Teeth

Some teeth may show some intrinsic discoloration that sheds a light on a condition you were born with, medication, or an injury. This type of discoloration is usually harder to fix and not as easy to remedy. Worn enamel can also lead to teeth that appear yellow. The dentin underneath your enamel is usually a slightly yellowish color.

Some tooth stains can be removed at home by brushing your teeth regularly. You can also try a whitening toothpaste, or brushing your teeth with a bit of baking soda. These products should be used with caution, as their abrasive nature can cause damage to your pearly whites.
