Most dentists agree that sugar, especially in the form of processed sweets, is pretty bad for your teeth. As dentists, we are used to telling patients about how important it is to brush and floss daily to maintain good oral health, but sometimes all our advice seems to fall on deaf ears. That’s why dentists take a more stern approach by no longer just telling patients what they should be doing but instead telling them what they must not do. Here is our list of 10 foods and drinks to avoid if you care about your dentist and, most importantly, your teeth:


Dentists are well aware that soda, or pop, has a lot of sugar. Dentists do not recommend limiting your daily intake of water to cut down on the dentist’s complaints you receive about your teeth. But if you want an excuse to drink more water instead of pop, let us convince you that it can at least be good for your teeth. The lack of acidity in plain water can help prevent tooth erosion, which is caused by acidic foods and drinks. Since many dentist visits are now focused on treating erosive tooth wear, drinking more fluids may actually prevent you from needing costly dentist treatments later down the road.


It’s not just the dentist who says fruit juice is bad for your teeth; the American Dental Association does too. Fruit juices typically have a lot of added sugar, which can lead to tooth decay. The ADA recommends drinking at least 6 ounces of water after you finish each cup of orange juice or other types of fruit juice if you don’t want to end up with dentist complaints. If you’re going to drink juice, choose 100% fruit juice without any added sugars or flavors and drink it in moderation.


Once again, dentists are fully aware that candy does not do a body good when it comes to teeth. Dentists recommend brushing your teeth after eating candy, but the dentist’s advice is to avoid eating a lot of candy in the first place. Dentists can advise patients on which types of candy are less likely to cause cavities based on the ingredients, but dentist visits for children with tooth fillings from eating too much candy are not uncommon.


Dentists recommend brushing your teeth after snacking on cookies because dentist appointments are easier to schedule than dentist drilling sessions. Seriously though, sugar is the dentist’s main concern when it comes to dentist complaints about cavities. Eating a few cookies here and there isn’t bad for your teeth if you brush right afterward, but dentists aren’t necessarily concerned about your dentist complaints due to mild sugar intake. Dentists are more concerned with the dentist’s concerns caused by sugary foods and drinks that you eat throughout the day on a regular basis.


Dentists say that eating some types of whole-grain breakfast cereals can be good for your dentist and your dentist’s view of life. However, if you eat too many sugary breakfast cereals on a regular basis, you will probably still have a dentist appointment sooner or later. Dentists recommend chewing sugarless gum after eating breakfast cereal to reduce dentist complaints about cavities while you’re waiting for your dentist appointment.

Fruit Juices

As we mentioned in the dentist’s complaints about the juice section, dentist appointments are easier to schedule than dentist drilling sessions. Drinking fruit juice all day long is not likely to lead to dentist concerns and dentist concerns because it does contain some vitamins and minerals that can help keep your body healthy inside and out. But drinking fruit juices throughout the day can contribute to dentist complaints that are caused by sugary drinks, which may eventually require dentist treatment.

Frozen Desserts

Another dentist complaint that dentists have about ice cream has nothing to do with the dentist’s concerns caused by excessive dentist complaints. Instead, dentist appointments are easier to schedule than dentist drilling sessions because of the sugar in some types of frozen desserts. Although there are dentist complaints about some frozen desserts being okay for your teeth, others can lead to cavities because of the dentist’s concerns that dentist concerns due to dentist concerns.

Tobacco products

Dentists are not concerned with the dentist’s concerns caused by excessive smoking of any kind. However, dentists are completely aware that using tobacco products can contribute to cavity concerns.  Dentists are happy to provide different types of treatments for cavity concerns depending on the severity of your dentist complaints.  If you smoke, dentist treatments are an option to consider. If you use tobacco, visit your dentist regularly for routine cleaning and checkups. Dentists are also happy to provide appropriate treatments for children who come into the dentist’s office with severe cavity concerns due to smoking or other types of tobacco products.

Fried or crunchy snacks

Tooth decay is a problem that many people have to face, and it’s often related to the types of foods that you choose to put into your mouth. If you’re someone who likes fried or crunchy snacks, such as french fries, potato chips, or corn chips, you may be putting yourself at a higher risk for tooth decay. Why? Because these types of snacks usually contain high levels of starch and sugar.

The problem with starch and sugar is that after they’re in your mouth and in contact with the bacteria present in plaque, they begin to break down. This produces an acidic environment that can eat away at your tooth enamel, thus increasing the risk for cavities.

Crunchy foods are also extremely abrasive, which means they can wear down your teeth’ protective layer of enamel, thus increasing the chance that your teeth will acquire cavities.

Sugarless gum

While it may seem like the best option when you’re craving something to chew on, sugarless gum is actually one of the worst things that you can put into your mouth during a bout with tooth decay. This is true because it contains xylitol, which is a type of sweetener, and most types of sweeteners are bad for teeth because they increase the risk for cavities.

In addition, sugarless gum typically contains no fluoride, which means that it won’t help strengthen your teeth or protect against decay. In fact, chewing a lot of sugarless gum could actually increase the amount of acid in your mouth and cause you to lose calcium from your tooth enamel, making them more susceptible to developing cavities.


In conclusion, avoid those high-sugar foods and if you must eat them, make sure to eat a lot of the good foods listed in this article with it. If you’re going to treat yourself to sugary food, be sure that you brush your teeth immediately afterward or chew on some sugar-free gum for an hour.

One thing to keep in mind is that although eating a lot of sugar can cause tooth decay, brushing your teeth immediately afterward or chewing on some sugar-free gum for an hour will help remove the cavity-causing bacteria from your mouth.
