Your diet can greatly effect the health of your teeth. There are many studies that show if you consume large amounts of sugar-filled foods and sweetened drinks, this can have a negative effect on the teeth. Specifically it promotes cavities and provides more opportunity for cavities to occur.
The most common oral diseases are cavities and periodontal diseases. Both have a very direct connection to the build up of plaque and bacteria in the mouth. Bacteria feed on sugar. The more sugar you consume, the more fuel the bacteria in your mouth have, and thus the bacteria can multiply much faster. Plaque is made up of bacteria. It is literally defined as a biofilm or mass of bacteria that grows on surfaces within the mouth. So, the more sugar you eat, the more the plaque can grow in your mouth!
Of course, it is not necessary to cut all sugar out of the diet. But it should be borne in mind that the more sugar you eat, the more this bacteria in your mouth can grow and cause problems. The proper cleaning of the mouth is imperative to anyone who eats food period. You should see your dentist every six months for a regular checkup and cleaning to ensure that you do not build up to much bacteria and plaque in the mouth.
