The Truth About Cavities: Causes, Prevention, and Treatment
Cavities are one of the most common dental issues affecting people of all ages, yet many misconceptions still surround how they form and how they should be treated. Understanding the truth about cavities is the first step toward protecting your smile and maintaining long-term oral health.
Cavities develop when plaque - a sticky film of bacteria - builds up on the teeth. These bacteria feed on sugars and starches from food and drinks, producing acids that gradually weaken and break down tooth enamel. Over time, this erosion leads to small holes in the teeth, known as cavities. Poor oral hygiene, frequent snacking, sugary beverages, dry mouth, and skipping regular dental visits all increase the risk.
The good news is that cavities are largely preventable. Brushing twice a day with fluoride toothpaste, flossing daily, and limiting sugary or acidic foods can significantly reduce plaque buildup. Fluoride plays a key role in strengthening enamel and helping teeth resist acid attacks. Routine dental checkups and professional cleanings are also essential, as they allow early signs of decay to be detected before cavities worsen.
When cavities are caught early, treatment is typically simple and effective. Small cavities can be repaired with tooth-colored fillings that restore strength and function while maintaining a natural appearance. If decay progresses deeper into the tooth, more advanced treatments such as crowns or root canal therapy may be necessary to save the tooth and prevent infection. Prompt care helps avoid discomfort, complications, and more extensive procedures.
