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. 

Talk to Dr. Michelle Slezewski and Dr. Paul Engibous at our Anchorage, AK office about which toothpastes can help restore a healthy balance between the ongoing cycles of demineralization and remineralization. While tooth-repair toothpaste can’t fix cavities, these products can often strengthen demineralized enamel and reverse this earliest stage of tooth decay.

You found the perfect toothbrush! The bristles are soft, to avoid irritating your delicate gum tissue. The angle of the bristles is perfect for removing plaque. The handle is durable and comfortable when you spend at least two minutes brushing in the morning and two at night. Why, you love this toothbrush and you’ll never let it go… for the next three or four months.

The life of a toothbrush is naturally a short one. Dr. Michelle Slezewski and Dr. Paul Engibous and our team recommend replacement every three to four months because the bristles become frayed and worn with daily use. They cannot clean as effectively when the bristles begin to break down, and, depending on your brushing style, may wear out even more rapidly. (Children will probably need to replace toothbrushes at least every three months.) But even in the short time you have your toothbrush, there are ways to keep it ready for healthy brushing.

• Don’t share. While sharing is normally a virtue, sharing toothbrushes can lead to an increased risk of infections, especially for those with compromised immune systems or existing infectious diseases. Similarly, keep different brushes separate when drying to avoid cross-contamination.
• Rinse thoroughly after brushing. Make sure to remove any toothpaste or debris left after you brush.
• Store the brush upright. Air-drying is the preferred way to dry your brush, as covering the brush or keeping it in a closed container can promote the growth of bacteria more easily.

There are several products on the market that promise to sanitize your brush. The verdict is still out on its success, but if you or someone in your home has a compromised immune system, call our Anchorage, AK office to see if it might be worth your while to check them out.

Even though your toothbrush won’t be with you long, make its stay as effective and hygienic as possible. And if you find a brush you love—stock up!

A famous mouthwash company chose the marketing slogan, “Better than flossing.” As a consumer, would you believe a high-end commercial that essentially tells you to stop flossing? Just use this brand of mouthwash and the risk of gingivitis, cavities, etc., is gone. What a wonderful idea! Now for the reality: This is simply not true.

The company that made these claims received some negative feedback for making this false claim. Does this mean that all mouthwashes are ineffective? Absolutely not. It takes a little bit of research to know which mouthwashes are most effective and best suited for you. Here are some key points to remember when choosing a mouthwash.

First, think about why you want to use a mouthwash. If you are at high risk for cavities, you would benefit from a fluoride mouthwash. Check the labels to see which ones contain fluoride.

If you have active gingivitis, a mouthwash with some antibacterial properties would be preferable. Read the labels carefully. You do not want a mouthwash containing alcohol. If you have active periodontal disease, an antibacterial mouthwash is appropriate, though you may want to discuss which kind would be best for your individual needs.

Prescription mouthwashes are also an option. You should pay close attention to the directions, such as how much and how long to use them. There is one brand in particular whose effectiveness can steadily diminish if you use it continually. There can also be side effects you should discuss with our office and/or your pharmacist.

Some great mouthwashes for kids change the color of plaque on their teeth to help them see how they are doing with their brushing. This is a great learning tool for the child and the parent! Why not pick up a bottle for yourself next time you’re at the store and evaluate your own performance?

Beware of claims that a mouthwash can loosen plaque. This is not accurate. Beware of any mouthwash that has alcohol. This is worth mentioning twice. Take care of your taste buds. If you are using a strong mouthwash, it can reduce your sense of taste.

These tips should help you choose the right mouthwash for your needs. Please contact Dr. Michelle Slezewski and Dr. Paul Engibous at our Anchorage, AK office with any specific questions!

Just like that, it’s Spring, and the world looks brighter! The skies are sunnier. Daylight in Anchorage, AK lasts longer. And your smile can be brighter, too—with a little bit of spring cleaning.

After all, sometimes dental habits become so automatic that we don’t pay them as much attention as we should. Without careful daily brushing and flossing, you could start to see surface staining on your enamel. Or red and swollen gums. Or tartar deposits along the gumline or behind your teeth. 

The start of the season is a good time to spring ahead with a plan for better oral health, and we have some simple ideas to help you clean and protect your smile all through the year.

Assemble the right tools.

• Use a soft-bristled toothbrush, because anything firmer can be hard on your tooth enamel and gums. If you’re having trouble removing food particles and plaque, an electric toothbrush might be a game changer.
• Find the right floss. If you’ve been neglecting flossing because it’s difficult, or if you have mobility issues, there are lots of options available to improve efficiency and comfort. Whether it’s floss picks, interproximal brushes, or water flossers, Dr. Michelle Slezewski and Dr. Paul Engibous can recommend the best products for your individual needs.
• Choose fluoride toothpaste. Fluoride not only helps prevent cavities by creating an unfavorable environment for cavity-causing bacteria, it also actually strengthens tooth enamel as well. Win/win!

Use those tools!

• Brush all the surfaces of your teeth carefully and thoroughly (no need to scrub) and brush along the gumline at a 45˚ angle. This will help prevent plaque from accumulating above and below the gumline, where it can harden into tartar.
• Brush often enough and long enough. The team at Pediatric Dental Associates generally recommends brushing twice a day, for two minutes each time. 
• If you wear aligners, a retainer, a mouthguard, a nightguard, or other appliances, brush your teeth before wearing them. You don’t want to trap food particles or bacteria in your appliance!
• Floss at least once a day, or more often as recommended. Proper flossing can be difficult sometimes, so ask Dr. Michelle Slezewski and Dr. Paul Engibous for the best techniques.

Make sure your dental products are in top shape.

• Replace your toothbrush as often as necessary. After three months or so, bristles start to fray. They don’t clean as effectively, and they could be abrasive to gum tissue. Change out your brush every three to four months, including the head on your electric brush. A good way to remember is to change your brush with the change of seasons. 
• Check the date(s)! Many toothpastes, mouthwashes, and other oral supplies come with a “best used by” date, ensuring that your products remain safe and effective.
• Choose the right toothbrush holder. Your brush should air-dry upright, because germs thrive in closed, damp environments. And your holder shouldn’t allow your brush to touch other people’s brushes to avoid transfer of bacteria and viruses. Clean your brush holder regularly to remove toothpaste residue and germs.
• Clean your aligners, retainer, mouthguard, night guard, and/or cases for your appliances as recommended. Bits of food, bacteria, viruses, and other germs collect there as well.

Work with the experts for your brightest smile.

• See Dr. Michelle Slezewski and Dr. Paul Engibous regularly. You’ll discover any problems which might be dimming your smile, and you’ll discover them early.
• Schedule cleanings with your exams. The team at Pediatric Dental Associates uses tools such as ultrasonic or hand scalers and polishers to remove stubborn plaque, tartar deposits, and surface stains that brushing can’t.
• If you want brighter, whiter teeth, consider professional whitening. While whitening kits are available in almost any drug store or supermarket, office treatments or kits provided by Dr. Michelle Slezewski and Dr. Paul Engibous use stronger ingredients and are more effective.

Easy steps, yes? Step up your cleaning routine, and you’ll have a springtime filled with not just brighter smiles, but healthier smiles, too!
