If you live on the coast, you know how amazing seafood can be.
It is not just about the delicious taste; the truth is that seafood, especially oysters, is full of important nutrients that help your whole body, including teeth and gums.
At Channel Islands Family Dental Office, with locations in Oxnard, Ventura, Santa Paula, Port Hueneme, and Newbury Park, we understand how much nutrition matters for strong teeth. That’s why we love sharing the top oysters benefits for your smile and overall oral health.
Let’s take a closer look at how oysters can support your teeth.
Eating oysters gives your body a big dose of helpful vitamins and minerals, including zinc, calcium, phosphorus, vitamin D, iron, vitamin B12, copper, and selenium.
These nutrients are especially important for adults over the age of 40. As we age, both men and women become low in some of these vitamins and minerals.
Now, let’s look at what these nutrients do for the mouth.
Zinc is one of the most common minerals in oysters.
Note: Dentists often recommend eating foods like oysters to people with gum problems.

Your body makes vitamin D from sunlight, but you can also get it from foods like oysters. Without enough vitamin D, the risk of gum disease and tooth decay may increase.
Vitamin B12 helps the body make red blood cells, which bring oxygen to gums and oral tissues.
