Will brushing my teeth prevent the spreading of my dental caries ?

Absolutely: Oral hygiene is the best way to prevent the spread of caries. Diets low in sticky foods and sugars will help as well. See your dentist regularly for professional cleanings to get those hard to reach spots.

Good hygiene helps: If by "spreading", you mean, transferring from one tooth to the next, then the answer is yes. When there is active dental decay present in your mouth, then the oral environment is not as healthy as it could be. The numbers of bacteria may increase putting other teeth at risk. Improving oral hygiene will definitely help slow the progression of untreated dental decay and prevent other cavities.

Tooth Brushing: Yes! brushing can prevent the spread of dental caries. But brushing alone is not enough. You must also add flossing in between your teeth to be able to do a complete job. If you only brush, you are missing 35% of the plaque in your mouth. More than half of all cavities are found between teeth using x-rays. If you already have cavities you need them removed and teeth repaired.
