07 Aug Can Fruit Be Bad for My Teeth?
It’s a fair question. Fresh fruit has a lot of vitamins and fiber and water, which are all good for your teeth. But it also has sugar, and some fruits have acids, which aren’t very good for your teeth. And the concentrated sugars in dried fruit and fruit juice might do more harm than good.
It all depends on the type of fruit, how often you eat it, and how it’s prepared. Some fruits are better for your teeth than others. Here’s our list of the best and worst ways to eat fruit.
Does Fruit Have Too Much Sugar?
There’s always going to be at least a little bit of sugar in fruit. With fresh fruit, that’s not usually a problem, because the sugar content is fairly low. When it comes to dried fruit, juice, and smoothies, however, that’s another story.
Eating Fresh Fruit Can Be Good for Your Teeth
The fiber in fruits like apples and pears scrubs your teeth as you chew. And fruits with high water content like (grapes and melons) help rinse away the sugar and keep your mouth clean.
The best fresh fruit to eat is pineapple, because it contains bromelain, an enzyme that breaks up plaque and helps get rid of surface stains. The worst is probably citrus. Lemons, limes, grapefruits and oranges have a lot of Vitamin C, which is good for your teeth, but their high acidity is not.
Dried Fruit Is Definitely the Worst for Your Teeth
Because it has the highest sugar content, dried fruit is the worst for your teeth. A lot of dried fruit snacks even have added sugar, and are really just candy in disguise. Plus, dried fruit is sticky, which means it clings to the grooves of your teeth until the next time you brush. It’s so sticky that it could even pull out a filling or loosen a crown that’s already impacted by
Fruit Juice Isn’t That Great, Either
Juice is basically concentrated sugar in liquid form. Juicing and straining fruit strips away the fiber that would normally slow sugar absorption, and most fruit juice is highly acidic besides. Sipping it slowly throughout the morning is actually worse for your teeth than drinking a full glass with a meal, since it keeps your saliva in an acidic state for much longer.
This isn’t just a dental office talking point. A peer-reviewed lab study on fruit juice and enamel wear measured actual enamel loss after tooth samples were exposed to common fruit juices under controlled conditions. The findings showed that acidity alone can contribute to enamel erosion, reinforcing that it’s not just sugar you need to worry about.
Fruit Smoothies Can Be Good or Bad
Blending keeps most of the fruit’s natural fibers intact, which makes smoothies better than juice. However, a smoothie can still deliver several servings’ worth of sugar in one sitting, especially with added honey or fruit juice.
Choosing the right combination of ingredients makes all the difference. For instance, adding a dairy product like yogurt can help neutralize the acidic nature of some fruits. And using unsweetened yogurt will help cut down on the sugar content.
Smart Snacking Between Meals
Sugar itself doesn’t cause cavities directly. The bacteria living in plaque feed on sugar and release acids as a byproduct, which wears away the tooth enamel and causes cavities. The more often your teeth are exposed to sugar throughout the day, the higher your risk of cavities.
That’s why frequent snacking is much harder on your enamel than eating sweets with a meal. Constant grazing keeps your mouth in an acidic environment most of the day. But as long as you’re drinking enough water and choosing smart snacks, you don’t have to break the habit entirely.
Here are a few smart snacking tips:
- Stay hydrated with sugar-free drinks.
- Opt for healthy snacks like fresh fruit salads and salsas.
- Fresh fruit with cheese makes a great healthy snack for kids as well!
- Drink water after snacks, and wait at least 30 minutes before brushing your teeth.
