Foods that Can Harm Enamel

March 11th, 2026

Many people who are careful about brushing and flossing their teeth wonder how they still end up with cavities or tooth decay. Several factors affect wear and tear on tooth enamel. Diet is a major factor, with certain foods increasing the likelihood that your enamel will become discolored or decayed. Pay close attention to the foods you eat to keep your pearly whites looking healthy and clean.

What causes enamel damage?

Tooth enamel refers to the hard, semi-translucent, whitish part of the tooth that shows above your gums. The enamel is primarily composed of minerals that are strong but susceptible to highly acidic foods. When acid reacts with the minerals in enamel, it results in tooth decay. Strongly pigmented foods can also damage enamel by discoloring the surface of the tooth.

Foods that harm enamel

Acidic foods are the greatest source of enamel damage. To determine whether a food is acidic, look up its pH. Scientists use pH, on a one-to-seven scale, to define the relative acidity or alkalinity of a substance. Foods with low pH levels, between a one and three, are high in acidity and may damage your enamel. Foods with high pH levels, such as a six or seven, are far less likely to cause enamel harm.

So which foods should you avoid? Many fruits are high in acidity, including lemons, grapefruit, strawberries, grapes, and apples. The high sugar and acid content in soda makes it another huge contributor to enamel decay. Moderately acidic foods include pineapple, oranges, tomatoes, cottage cheese, maple syrup, yogurt, raisins, pickles, and honey. The foods that are least likely to cause enamel damage include milk, most cheeses, eggs, and water.

Beverages such as red wine and coffee also damage the enamel by discoloring it. Although stains do not necessarily undermine the integrity of your teeth, they can be unsightly.

What can I do to prevent enamel damage?

Fortunately, there are several measures you can take to prevent your enamel from discoloring or decaying. The easiest way to avoid decay is to steer clear of high-acidity foods. This may not always be possible, but eliminating sugary fruit juices and soda from your diet is a good start. Brushing your teeth after each meal and flossing frequently also preserves your enamel. Another good idea is to rinse your mouth with water or mouthwash after eating to wash away high-acidity particles.

Although enamel damage is common, it does not have to be an inevitable occurrence. Knowing the foods that harm your teeth gives you the tools to prevent discoloration and decay. With some easy preventive measures, your teeth will stay strong and white for years to come! Give us a call at Robert H. Perry Specialist in Orthodontics to learn more!

Oral Health Tips: Travel Edition

March 4th, 2026

When you leave on a trip, you probably double-check that evrything’s ready: your clothes are packed, your ticket is handy, and your passport waits patiently on top of your bag or in a special pocket.

The same level of preparedness should apply with regard to caring for your oral health when you’re about to leave home for a while. Whether you’re jumping in the car for a weekend camping trip or flying halfway across the globe for a longer stint, the tips below will help you keep your teeth healthy whil you’re away.

Prepare Ahead of Time

The key to maintaining good oral hygiene during travel is preparation. Schedule a regular dental appointment so your teeth are freshly cleaned and ready before you leave. This can identify potential issues that might cause problems while you’re away.

If you have any items on a dental “to-do” list, such as wisdom tooth removal, replacement of a filling, or orthodontic adjustment, it’s a good idea to get those procedures completed before your trip.

En Route

If you’re stuck on a long flight or trekking far into the woods, you might find yourself where there’s no sink or even a toothbrush at hand. We speak for everyone when we say that nothing is worse than a mouth that feels, shall we say, less than fresh.

A lemon wedge or Granny Smith apple slice can help freshen up your breath when you’re in need of a quick fix. Rinsing your mouth thoroughly with water can help to wash away bacteria that causes cavities and reduce that gritty sensation. If you’ve got toothpaste, put a dot on your finger or a damp washcloth to serve as a makeshift toothbrush.

Nowadays, travel-sized dental products are available at most grocery stores and pharmacies. You can find travel toothbrushes, mini mouthwashes, and pocket-sized floss to slip into your travel bag.

Colgate makes disposable mini-toothbrushes called Wisps that can help you freshen up when you may not have access to a regular toothbrush. Packing a few extra dental supplies may also be a good idea in case one gets damaged or lost.

At Your Destination

Traveling abroad can expose you to unfamiliar conditions. Some countries have compromised water sources that will make you extremely ill if ingested, even from the tiny amount of water with which you wet your toothbrush.

Minimize that risk and keep bottles of water on hand instead for rinsing your mouth and toothbrush. If your toothbrush comes in contact with contaminated water, swapping it out for a new one is the safest option.

Storing your toothbrush properly is necessary to prevent bacteria from growing on it. Place your brush in a Ziploc bag when you’re on the go and allow it to breathe once you get to a temporary destination.

Traveling near or far should be an enjoyable experience. Dental issues shouldn’t be a source of worry on your vacation. As long as you’re prepared and take precautions, your teeth can stay healthy even when they’re out of the country!

Of course, if you have any questions, don’t hesitate to contact our Corinth, MS office.

Can Toothpaste Repair Tooth Decay?

February 25th, 2026

It seems like the ads are everywhere these days—repair your enamel and reverse tooth decay with a tube of toothpaste! Are these claims too good to be true? Let’s dive into the science of tooth decay—how decay develops and how (and if!) it can be reversed.

Teeth can stand up to the powerful pressures of biting and chewing because over 95% of our enamel is made up of minerals. Calcium and phosphate ions in our teeth bond to form a crystal structure called hydroxyapatite. Because of the strength of this crystalline design, tooth enamel is the hardest substance in our bodies, even stronger than our bones. 

But bones, like most other parts of our bodies, are living tissue, which means that they can create new cells to replace old or damaged cells. Tooth enamel can’t regenerate new cells to repair itself. This means that when a cavity has made a hole in the tooth, the enamel can’t grow back. And, while enamel structure is very strong, it’s also vulnerable to damage—specifically, damage from acids. 

Our teeth are exposed to acids throughout the day, whether they are acids created by plaque bacteria or the acidic foods and drinks we consume. Acids dissolve mineral bonds, stripping calcium and phosphate minerals from the enamel and leaving weak spots in the tooth surface. This process is called demineralization. Demineralization is the first stage of tooth decay.

The good news? Our bodies are designed with a built-in defense mechanism to prevent demineralization from causing lasting damage. All through the day, saliva helps wash away acids in the mouth and bathes our teeth with new calcium and phosphate ions. These ions bond with the calcium and phosphate in our enamel, restoring enamel strength. This protective repair process is called remineralization. 

Now for the bad news. In the tug of war between demineralization and remineralization, saliva can only do so much. If your diet is heavy with acids, if you don’t brush away acid-producing plaque bacteria regularly, if you eat a lot of the sugars and starches which feed plaque bacteria, the remineralizing effects of saliva can’t keep up with the demineralizing effects of acids.

The first visible sign of demineralization is often a white spot on the tooth where minerals have been stripped from enamel. Studies have shown that enamel-strengthening toothpaste can be effective in this very first stage of tooth decay. Toothpastes which advertise enamel repair generally contain one or more of these ingredients:

  • Calcium Phosphate
  • Hydroxyapatite
  • Fluoride 

Toothpastes with calcium phosphate or hydroxyapatite contain calcium and phosphate minerals, the building blocks of tooth enamel. Studies have suggested that these minerals can replace the calcium and phosphate ions stripped from enamel. These toothpastes may or may not contain fluoride, which is something you should discuss with your dentist before deciding on a specific toothpaste.

Fluoride toothpastes remineralize enamel—and more! Fluoride ions are attracted to the tooth’s surface, and, when fluoride ions join with the calcium and phosphate ions there, they form fluorapatite. Fluorapatite crystals are larger, stronger, and more resistant to acids than hydroxyapatite crystals. And, once bonded with tooth enamel, fluoride attracts the calcium and phosphate ions in saliva to remineralize the teeth more quickly. 

Why consider enamel-repair toothpaste? 

Once enamel is gone, it’s gone for good. If excess demineralization isn’t treated, a weak spot on the tooth surface will continue to erode, growing bigger and deeper until it becomes a hole in the enamel. This is a cavity, and your dentist will need to treat and repair your tooth to prevent the cavity from growing and potentially exposing the tooth’s pulp to bacteria and infection. 

If you wear braces, you want to be especially careful about excess demineralization. Because it can be hard to brush and floss effectively with braces, white spots and discolored patches are a common concern for those with braces, especially on the enamel around brackets.  

Talk to Dr. Perry at our Corinth, MS office about which toothpastes can help restore a healthy balance between the ongoing cycles of demineralization and remineralization when you have braces. While tooth-repair toothpaste can’t fix cavities, these products can often strengthen demineralized enamel and reverse this earliest stage of tooth decay.

Which mouthwash should you use?

February 18th, 2026

Although using mouthwash is certainly not the equal of brushing and flossing, it does have benefits for your dental hygiene. If you use mouthwash regularly, you should find out which type is best suited for your needs. Here are some things to think about the next time you’re at the store.

The first item to weigh is why you want to use mouthwash. If the reason involves a high risk for cavities, you should focus on a mouthwash that contains fluoride. Make sure to double-check the label, because some mouthwashes do not necessarily include fluoride.

If you’re looking for a mouthwash to fight gingivitis, select an oral rinse with antibacterial properties. Make sure to read labels and avoid picking one that contains alcohol. Antibacterial mouthwash would also be best for a patient who has periodontal disease.

Another option is prescription mouthwash. These should be discussed with Dr. Perry and/or your pharmacist in order to avoid negative side effects. Pay close attention to the directions regarding how much to use and for how long. Keep in mind that some brands may lose their effectiveness if you use them on an ongoing basis.

For children, you can find a mouthwash that changes the color of plaque on their teeth. This is a fun way to help them understand how well they are brushing, and what areas they need to focus on. It can even be a tool for adults who have trouble reaching certain areas of their mouth.

While mouthwash is generally considered as a safe means to improve your oral health, you need to keep certain things in mind. Avoid using any mouthwash that has alcohol in it. If you are using a strong one, it can reduce your sense of taste over time. Be wary of a mouthwash that claims it can loosen plaque; this is not accurate and can mislead consumers.

We hope these simple suggestions will help you the next time you’re at the store. Make sure you pick the right mouthwash to keep that healthy smile! Feel free to contact Dr. Perry at our Corinth, MS with any questions you may have.
