Everything Sweet as a Gum Food
Sugar is one of the worst dietary enemies when you want to prevent problems with your gums and teeth. That’s because when you eat sugar, it becomes acids in your mouth that can eat away at the collagen fibers that hold your gums together. That can lead to bleeding gums and gum disease, two very common and treatable issues that people don’t usually have to worry about if they keep their sugar intake below a certain level.

If you have diabetes, it’s especially important to avoid sugar and other high-glycemic foods because they can increase your risk of gum disease.
Processed Foods for Gum Health
Diets high in processed foods are also a recipe for problems with your gums and teeth. That’s because many processed foods, including things like soda and packaged baked goods, contain large amounts of sugar. As we said earlier, sugar and other high-glycemic foods can harm your gums, so if you eat a lot of processed foods, you’re putting your mouth at risk.
Processed foods also contain large amounts of preservatives and chemicals that can irritate your gums and make them more susceptible to infection. Are you wondering how you can avoid eating processed foods? Simple! Stick to whole, unprocessed foods like fruits, vegetables, grains, and legumes. That will help you avoid the negative effects of eating processed food.
Smoking or Tobacco on Oral Health
If you want healthy gums, it’s a good idea to avoid smoking. That’s because smoking can cause your gums to recede, leading to gum disease and other oral issues like tooth decay. Additionally, smoking tobacco can make you more likely to develop bad breath and a lingering tobacco smell in your mouth. Both of these things may be signs of gum disease or other serious oral health issues. If you want to prevent gum disease, it’s a good idea to avoid smoking

Coffee and Tea for Gums
Finally, if you want healthy gums, you should avoid drinking too much coffee and tea. That’s because both beverages are high in tannic acid, a chemical compound that can contribute to gum disease. In fact, one study found that people who drank 5 or more cups of coffee a day had an increased risk of developing gum disease. If you want healthy gums, you should drink less coffee and tea and see if you notice a difference in the state of your gums.
In addition to being high in sugar, sports drinks can also erode gums and promote tooth decay, because they are also high in acid. A 2012 study found gums and teeth are attacked by the acid in sports drinks, after five consecutive days of exposure to them. If you or your child is drinking sports drinks after exercise sessions, either look at labels to find the brands lowest in added sugars or try switching to water.
One easy way to support gum health is to have a diet of healthy foods that provide plenty of nutrients, and build strong and healthy teeth and gums.
Here are foods you can eat that protect Gum Health
1. Fresh Fruits and Vegetables
Fresh fruits and vegetables that are crunchy and full of fiber can help keep teeth clean and healthy, and lower the risk of plaque build up. Chewing delicious crunchy vegetables can actually help keep your teeth cleaner and support gum health.
2. Milk, Yogurt, Dairy
Foods high in calcium are obviously healthy for your teeth, but did you know they also help with other facets of oral hygiene? Yogurt helps encourage healthy bacteria in the body, which is another thing that may help prevent cavities.



3. Water
Drinking plenty of water throughout the day helps keep teeth clean and healthy as it washes away food particles regularly. Preventing the build up of plaque this way is an important way to support gum health.
4. Sugar Free Gum
Sugar Free Gum is a great way to freshen your breath and keep your teeth clean between meals. Be sure it is indeed sugar free.

6. Nuts
Nuts like Almonds are low in sugar, high in fiber and minerals like calcium that help encourage healthy teeth and gums.
7. Whole Grains
Whole grains are one food that can promote gum health and reduce the risk of periodontal disease.
