Every person on earth has bacteria in their mouth. After eating or drinking sugar reach things bacteria in your mouth turn the sugar into acid. A plaque starts forming on your teeth. This plaque can lead to tooth decay, cavities, tartar, loss of teeth, or even dental caries called cavities.

Inconsistent brushing and flossing like brushing your teeth once in a while, not brushing your teeth long enough, or not brushing your teeth at all allow food particles to remain on the surface of the teeth and destroy your oral health.

3) Dry Mouth

Less saliva flow which causes dry mouth increases the risk of tooth decay. Because the more dry mouth equals increased decay of the tooth. Additionally, saliva has the utmost importance to maintain good oral health and prevent tooth decay. Saliva helps break down and wash away food particles by keeping the mouth wet. Additionally, it strengthens and safeguards teeth against acids and plaque. Also, dehydration brought on by inadequate water intake results in a dry mouth.

Can Tooth Enamel Cause Decay?

Tooth enamel can definitely cause tooth decay. After you eat, bacteria in your mouth make acids from sugars and destroy your enamel. After some period of time, the erosion starts which damages the tooth to decay. After the enamel has gone, the tooth’s soft inner surfaces will be exposed to the surroundings and any food and liquid you consume. The damaged tooth will therefore be more exposed to discoloration or staining. The sensitivity of your tooth to hot and cold foods and beverages will also increase.
