Those are probably the two words no one ever wants to hear the dentist say after an exam is done. But it happens. The word cavity gets tossed around alot. But do you even know what exactly a "cavity" is and how it even happens??
Cavities are hollows left in your teeth when decay happens. Decay or "dental caries" is actually an oral disease- a bacterial infection, in your mouth. When this bacterial infection builds up your teeth, it forms plaque. Having this bacteria doesn't necessarily mean you have tooth decay. But when the bacteria interacts with sugars and starches, enamel eating acid is created.
So your first defense against tooth decay is your diet. Try to limit sugars and starches, foods that stick in your teeth, excessive acidic foods, and soft drinks.
Your second defense against tooth decay is keeping your teeth clean! Brush your teeth twice a day and be sure to floss so there's less chance of creating acids that can wear down tooth enamel.Brushing also counteracts the plaque and tartar that's building up over time. And remember, that even with your own consistent care at home, regular professional checkups and cleanings are vital for sound oral health.
