Have you ever heard of selenium? This trace mineral plays a vital role in your overall health, and that includes your oral health! Let’s delve into the fascinating world of selenium and see how it can keep your smile bright and healthy.
What is Selenium and Why Do We Need It?
Selenium is a mineral found in soil, water, and some foods. Our bodies only need small amounts of selenium, but it plays a big role in many important functions. According to the National Institutes of Health (NIH), selenium is important for thyroid hormone metabolism, DNA synthesis, reproduction, and protection from cell damage. Studies have also shown that selenium may help reduce the risk of certain cancers and heart disease.
Selenium in Dental Science
How do selenium and oral health relate to each other? To start, selenium is a friend to your teeth and gums, as it is a natural part of your tooth enamel and dentin. Research suggests that selenium may help fight gum disease and cavities. Selenium deficiency has been linked to an increased risk of gum disease. Selenium also has antioxidant and anti-inflammatory properties, which may help protect your gums and other oral tissues from damage.
Organoselenium sealants, which contain selenium, are used by dentists to prevent cavities and plaque buildup. Furthermore, selenium nanoparticles (SeNPs) are being studied for their potential antimicrobial effects against oral pathogens. However, more research is needed to assess their effectiveness in clinical settings.
How Much Selenium Do We Need?
The recommended daily intake of selenium for adults is 55 micrograms (mcg). Most people get enough selenium from their diet, but some people may be at risk for deficiency. People with certain medical conditions, such as cystic fibrosis or Crohn’s disease, may have difficulty absorbing selenium from food. Additionally, soil in some areas is naturally low in selenium, which can lead to lower levels in the food grown there.
Be aware that selenium deficiency is a concern, but so is selenium toxicity. Symptoms of selenosis (selenium poisoning) include gastrointestinal upsets, hair loss, white blotchy nails, garlic breath odor, fatigue, irritability, and mild nerve damage.
How to Get More Selenium in Your Diet
- Brazil nuts: These are the champions of selenium! Just one Brazil nut contains almost 1000% of your daily recommended value! However, be careful not to go overboard – too much selenium can be toxic.
- Seafood: Tuna, sardines, and shrimp are all great sources of selenium.
- Meat, poultry, and organ meats: Animal products are generally high in selenium. Just choose meats from animals raised on selenium-rich soil.
- Eggs and dairy: These contain a moderate amount of selenium and are a good option for those who don’t eat meat.
- Grains and cereals: Many grains and cereals are fortified with selenium.
Can You Take Selenium Supplements?
Selenium supplements can be helpful for people who are deficient in selenium, but it’s important to talk to your doctor before taking any supplements. Too much selenium can be dangerous, and supplements can interact with certain medications.
Working Towards That Better Smile
Selenium is a powerful mineral that can benefit your overall health, including your oral health. By incorporating selenium-rich foods into your diet and talking to your doctor about your individual needs, you can ensure that you’re getting enough of this essential mineral to keep your smile healthy and strong.
