It may sound surprising, but the bacteria that cause cavities can actually be transmitted from person to person. Streptococcus mutans, the primary bacterium responsible for tooth decay, can be passed through saliva, which means sharing utensils, cups, or even kissing can transfer cavity-causing bacteria.
This is particularly important for parents of young children. Sharing spoons, blowing on food, or cleaning a pacifier in your mouth can introduce harmful bacteria to your child's mouth before their immune system and oral flora are fully developed.
The best defense against cavities, whether your own or transmitted, remains consistent oral hygiene. Brush twice daily, floss regularly, limit sugary foods and drinks, and visit your dentist for regular checkups. At My Scottsdale Dentist, we help patients of all ages build healthy habits that prevent decay.
