Just thinking about bacteria might make you cringe, but it’s essential for your oral health. Your mouth is home to hundreds of bacteria species, but not all are beneficial. Brushing and flossing keep bacteria growth under control, so you might think your mouth is pretty clean. However, you’ve probably heard “A dog’s mouth is cleaner than a human’s mouth.” Here are the facts behind this common expression.
Dog’s Mouth VS Human’s Mouth
There are significant differences between your mouth and that of your four-legged companion. Both human and dog mouths are home to hundreds of microbes. Some bacteria species are present in human and canine mouths. However, several species present in your dog’s mouth aren’t in yours.
Porphyromonas is one example. It’s in a bacterial family linked to periodontal disease in both dogs and humans. Dogs have P.gulae, while humans have P.gingivalis. Both can cause significant dental and health problems.
On average, dogs have over 600 different types of oral bacteria. Harvard researchers have found that humans have about 615 types. Although a dog’s mouth may be slightly cleaner, you may not want to swap kisses. Most bacteria in their mouth aren’t zoonotic, which means you won’t get any diseases from them. However, dogs are notorious for getting into trash, litter boxes, and other items that can expose you to salmonella if you swap spit.
Combat Oral Bacteria Levels
Thankfully, humans can help control oral bacteria that can harm teeth and gums. Your home oral hygiene habits are your first line of defense against cavities, gum disease, and bad breath, which all result from bad bacteria.
The American Dental Association recommends brushing your teeth at least twice daily, if not after every meal. Clean all surfaces of your teeth and tongue for 2 minutes using a soft-bristled toothbrush and fluoride toothpaste. Clean between each tooth daily using high-quality floss. Finish your oral hygiene routine with an antimicrobial mouthwash.
Eat nutritious foods and limit your consumption of sugars and starches, which feed oral bacteria. If you can’t resist a piece of candy or a handful of chips, brush your teeth after you’ve finished.
Besides keeping your mouth clean at home, visit your dentist for a cleaning and checkup every 6 months. They’ll remove plaque and tartar buildup that harbors bacteria. They will also examine your mouth to look for anything concerning, like decay.
With the correct habits at home and regular care from your dentist, you’ll keep your mouth squeaky clean for a beautiful smile you’ll be proud of.
