The things you eat inﬂuence your oral health in positive and negative ways. While some foods may prevent cavities and help protect your teeth, others can do the opposite. Here are some tips to help you understand foods that are good for teeth, and foods that are bad.
Foods You Should Avoid
Citric acid is what gives citrus foods that zing we all love, but it can wear down your teeth. Lemons are the worst culprit, potentially causing the most erosion compared to limes, grapefruit and other citrus fruits1. They are healthy in moderation, but consuming them too frequently can cause damage to your teeth2.
Sugary Foods & Drinks
Dental professionals and parents alike have long discouraged children from consuming sweets and soft drinks. While they may bring a smile to your face with their sweetness, the sugar in these foods and drinks increase your risk for cavities—especially for children3.
When it comes to drinking alcohol responsibly, it’s important to consider the effects it may have on your teeth, too. Drinking alcohol signiﬁcantly increases your risk for gum disease, which puts you at risk for other health issues4. Not to mention, no matter how beautiful the red wine looks in your glass, its stains don’t look as great on your teeth.
Looking for an alcoholic beverage that’s better for your teeth? You should know that they all carry some risk. However, lighter colored alcohol can help you avoid stains. On the other hand, the antioxidants in red wine may prevent heart disease (along with staining your teeth). Avid red wine drinkers can use izzo’s Polishing Cup Head and Polishing Paste to gently remove stains after they indulge5. If you choose to consume alcohol, make sure you do it in moderation to reduce your risk for cavities, tooth loss, and gum disease.
Foods Your Teeth Will Love
Ever wonder which foods and drinks can help improve the look and health of your teeth? There are many to choose from, each containing vitamins and minerals that are beneﬁcial for healthy teeth and gums, and other parts of your body!. Calcium and vitamin D promote healthy teeth and bones, while vitamins B12, C, D, and E prevent cavities and tooth loss6. The following foods are probably already part of your diet, and they’re easy to eat more often to support a healthy smile.
For decades, public health campaigns have encouraged parents to give their children milk, cheese, and other dairy products to help support strong bones because they’re a great source of calcium and vitamin D. Since both teeth and bones need calcium, it would make sense that consuming dairy would have a protective effect. Studies show that milk, yogurt, cheese, and other dairy options protect your teeth from decay and cavities7, 8. So, add a glass of milk to your next meal or choose cheese or yogurt for your midday snack to help protect your pearly whites!
Fruits & Vegetables
They say an apple a day keeps the doctor away, but it might also prevent frequent visits to your dentist! While fruits and vegetables are great for digestion, the ﬁbrous composition also helps clean your teeth as you chew.
If that wasn’t enough, they also contain vitamin C and increase saliva production, which helps repair damage caused by bacteria9, 10.
The warm comfort of freshly brewed green tea can lift your spirits on the coldest of days. It also has anti-fungal properties that can kill yeast, which may cause cavities and tooth decay11, 12! Drinking it regularly will have others green with envy over your pearly whites.
Sugar Free Gum
The next time you pop a stick of sugar-free gum in your mouth, remember it does more than freshen your breath. Chewing sugar-free gum has numerous beneﬁts. It increases the amount of healthy bacteria in your mouth and if it contains xylitol, it does much more13! Xylitol is a sugar alcohol that is a leading alternative sweetener for sugar-free gum. It reduces the amount of plaque on your teeth, decreases swelling in your gums, and prevents cavities14. Try chewing it after meals to promote good oral health and get that clean, minty feel.
Choose Your Diet Carefully
Being mindful of the foods you eat can help protect your teeth from erosion, decay, and other dental worries. A healthy diet is a great complement to a healthy oral care routine. Use izzo’s 4-in-1 Oral Care System in between meals to put your best smile forward everyday!
