Dental Caries: Diseases & Prevention | Tooth Decay | ScienceMonk
Bacteria do not attack tooth suddenly or by chance, they grow over time due to the consumption of excess sweets, beverages containing acids, food debris, improper brushing, etc. It is essential to understand that once these microbes stick onto the tooth surface it creates an attachment between the microbe enzyme and the contents of the tooth, the microbes containing acid start deteriorating the tooth material initiating the dissolution of enamel, thus reaching the dentin over time and hence reaching the root canal stage.
