Dental caries or cavities is a breakdown of teeth due to acids produced by bacteria. The cavities may be of different colors from yellow to black. Symptoms may include pain and difficulty with eating and food lodgment (accumulation of food within cavity)
Dental caries is caused by the action of acids on the tooth surface. The acid is produced when sugars (mainly sucrose) in foods or drinks react with bacteria present in the dental biofilm (plaque) on the tooth surface.
Dental caries is a transmissible bacterial disease, a process caused by acids from bacterial metabolism diffusing into enamel and dentine and dissolving the minerals. The caries is a process which results from many cycles of demineralization and re-mineralization.
Brush your teeth at least twice a day with fluoride-containing toothpaste especially before going to bed. Clean between your teeth also, daily with a dental floss or interdental cleaners, such as the Oral-B Interdental Brush, Reach Stim-U-Dent, or Sulcabrush.
