Gingivitis vs Periodontitis: What’s the Difference?

August 22, 2025

When it comes to gum health, you’ll often hear two terms: gingivitis and periodontitis. They sound similar, but they aren’t the same. Understanding the difference can help you protect your smile and catch problems early.


Gingivitis is the earliest stage of gum disease. It happens when plaque builds up along the gumline, leading to redness, swelling, and bleeding when you brush or floss. The good news? Gingivitis is usually reversible with proper dental cleanings and good oral hygiene at home.


Periodontitis, on the other hand, is a more serious condition. If gingivitis goes untreated, the infection can spread deeper into the gums and supporting bone. This leads to gum recession, pockets around the teeth, and eventually even tooth loss. Unlike gingivitis, periodontitis can’t be reversed — but it can be managed with professional treatment.


So, the key difference is this: gingivitis is early, mild, and reversible; periodontitis is advanced, damaging, and requires long-term care. Catching gum disease in its earliest form is the easiest and most affordable way to keep your gums — and your teeth — healthy.

Fillings at 30: What’s Average and When to Be Concerned About Cavities

October 4, 2025
Did you know the average adult has a few dental fillings by the time they’re 30? Cavities are one of the most common dental issues, and fillings are the standard treatment. But just how many fillings are normal at 30—and when should you be concerned? Research shows that most adults in the U.S. have around 3–4 dental fillings by the time they’re 30. Some lucky people have none, while others may have more if they experienced frequent cavities as kids or skipped regular dental checkups . Having a few tooth fillings in adulthood is very common and nothing to be embarrassed about. Why Some Adults Have More Fillings The number of fillings you have at 30 depends on several factors: Diet: High sugar intake often means more cavities and more fillings. Oral hygiene: Daily brushing and flossing help prevent tooth decay. Genetics: Some people are simply more prone to cavities. Dental care: Routine exams and cleanings catch cavities early before they need larger fillings. When to Worry About Cavities and Fillings A handful of fillings at 30 is normal. But if you’ve had 8–10 or more cavity fillings by age 30 , it could be a sign of high cavity risk. That doesn’t mean your teeth are unhealthy—it just means tooth decay prevention should be a bigger focus going forward.
