Brooklyn residents often wonder whether their tap water is helping or harming their dental health. One key factor in this debate is
fluoride, a naturally occurring mineral added to public water supplies to prevent cavities. But does Brooklyn tap water really protect your teeth from decay? In this blog,
we’ll uncover the truth about fluoride levels in NYC’s water and whether it plays a significant role in cavity prevention.
What is Fluoride and How Does It Prevent Cavities?
Fluoride is a mineral known for its ability to strengthen tooth enamel and reverse early signs of tooth decay. It works by:
- Remineralizing enamel, making teeth more resistant to acid attacks.
- Inhibiting bacteria that cause cavities.
- Reducing demineralization, which slows down tooth decay progression.
For decades, fluoride has been added to public water supplies in the U.S. to improve dental health. But how does Brooklyn’s tap water measure up?
Is Brooklyn Tap Water Fluoridated?
Yes! Brooklyn, like the rest of New York City, receives fluoridated water. The New York City Department of Environmental Protection (DEP) maintains fluoride levels at 0.7 milligrams per liter (mg/L), which aligns with the U.S. Public Health Service’s recommendations.
This means that Brooklyn residents who regularly drink tap water are getting a beneficial amount of fluoride to help prevent cavities.

Sudden gum swelling is a dental condition that requires immediate attention, even if there is no pain. Gum health is often overlooked, but it is essential for overall oral well- being. Swollen gums may seem harmless at first, but they often indicate underlying issues that can worsen if left untreated.
Many people think of dental emergencies as situations with severe pain, but it's important to understand that discomfort isn't always a reliable sign of serious problems. Just because there is no pain doesn't mean there is no risk. Sudden gum swelling should be treated as an emergency , emphasizing the need for prompt professional evaluation.
Ignoring swollen gums can lead to more severe complications, affecting both oral health and general wellness. By understanding the seriousness of this condition and
seeking timely intervention, you can prevent further damage and ensure that your gums—and teeth—stay healthy and strong.
A skilled dental team can properly assess and treat any swelling. Prioritize your gum health by taking action when you notice unusual changes, protecting your smile for the future.
It's important to remember that maintaining good oral hygiene, including flossing your teeth regularly , can help prevent conditions like gum swelling.

By the age of 6-7, the primary teeth start to fall out to make space for the permanent teeth. These permanent teeth are the ones that will stay with them for the rest of their lives. However, there are certain oral problems such as tooth decay, lip sucking, and early teeth loss.
