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. Gregory Weaver at our Raleigh, NC 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.

Modern dentistry has made the most of today’s technological innovations. And we’ve come a long way from the fraying sticks our ancestors used as toothbrushes.

On the other hand, while it’s a lot better than a fraying stick, the manual toothbrush model you’ve used for years might be ready for an upgrade. Should you take this opportunity to try out some new technology offering all the bells and whistles? Let’s answer that question by asking a few more questions.

Happy with your manual brush?

If you like your manual toothbrush and it’s doing the job, by all means, stick with it. But even your old familiar brush can evolve:

• There are lots of bristle options, but soft bristles are almost always the way to go. Medium and hard bristles can be too abrasive for your enamel.
• Heads come in a variety of sizes, so make sure the head size is comfortable. You want to be able to maneuver to reach every tooth surface, which a too-large brush head just can’t do.
• Try a different handle shape if you’re having trouble maneuvering and keeping a firm grip.
• Change your brush regularly. Brushes are effective for about three months before the bristles start to fray and breakdown. This is a good opportunity to experiment with different brands and styles.

Does your old brush suit your current needs?

Different types of manual toothbrushes are available for effective and comfortable brushing when you need options that a typical brush doesn’t provide:

• Special orthodontic toothbrushes are designed with bristles trimmed to fit around brackets and wires and smaller heads to reach into tight places.
• For those with mobility issues, brushes with larger or easy-grip handles make cleaning more comfortable.
• Brushes with extra-soft bristles are available if you have enamel erosion or sensitive gums.
• Because many women find their gums become especially sensitive during pregnancy, there are brushes designed especially for moms-to-be.

Is it time to go electric?

If you haven’t tried an electric toothbrush before, you might find that getting braces is a great reason to give one a spin.

• Electric toothbrushes can outperform manual models. A dedicated brusher might manage hundreds of brushstrokes for each minute of brushing, while an electric brush can provide thousands. If, despite your regular brushing, you have plaque build-up, an electric brush might be a good alternative to your manual brush.
• Models are available which can alert you when you’re brushing too hard—which is important for your enamel if you’re a heavy-handed brusher.
• If you tend to *think* you’ve brushed for the recommended two minutes, but have *actually* brushed 32 seconds, some electric brushes come with timers!
• There are tapered electric orthodontic brush heads designed just for people with braces.
• Electric brushes have bigger handles and can be easier to grip.

Is your current brush doing the job?

So, should you stick with the familiar toothbrush that’s worked for you all these years, or take this opportunity to try out some new technology that offers all the bells and whistles? The answer is clear: the right brush for you is the one that works!

If your regular checkups show that plaque is under control, you’re doing just fine with the brush in hand. If you or Dr. Gregory Weaver notice plaque buildup, it’s time to consider making some changes. Whether it’s a question of tools, techniques, or time spent brushing, your Raleigh, NC dental team has the answers you need for state-of-the-art dental hygiene.

It’s the littlest month of the year, so what better time to think about the dental health of our littlest family members? February is National Children’s Dental Health Month, and we’re here to suggest some of the best dental habits for healthy childhood smiles.

Babies 

• Even before your baby cuts her first adorable tooth, you can start proactive dental care by gently wiping little gums with a clean, moist gauze pad or soft cloth twice a day. This removes bacteria and food particles and helps prepare your baby for brushing.
• When that first tooth does appear, or by age one if it hasn’t yet erupted, it’s time to schedule a visit to the dentist. At this first visit, your child’s dentist will check jaw and tooth development and can give expert guidance on teething, brushing, how much and which kind of toothpaste to use, and topics like thumb-sucking and pacifier use.
• When baby teeth arrive, use a small soft-bristled toothbrush designed to fit comfortably in tiny mouths.
• Use toothpaste as recommended. Children under the age of three who use paste should use a very small amount, no larger than a grain of rice.
• Prevent “baby bottle tooth decay”—don’t put your baby to bed with a bottle. This allows the sugars in formula or, when your child is 12 months or older, milk, to bathe the teeth throughout the night. And babies and toddlers never need sugary juices or sodas in those bottles!

Toddlers 

• Help your child develop a positive relationship with his dental team. Read books or watch videos to help your child learn what to expect. Practice with him by having him open his mouth while you count his teeth. Plan visits when your child isn’t hungry or tired. Be positive yourself—your child will take his cues from you!
• Schedule regular appointments for exams and cleanings. Dr. Gregory Weaver will check tooth and jaw development, look for any signs of decay, and evaluate potential problems such as prolonged thumb sucking or pacifier use. 
• By age three, children have most or all of their baby teeth. Use a soft bristled brush to clean your child’s teeth twice each day. As she grows, demonstrate how to brush properly. The dental team at Weaver Dentistry will have some great ideas on technique!
• Daily flossing should begin as soon as your child has two teeth which touch. 
• Around age six, your child may be transitioning to solo brushing and flossing—but your oversight is still needed. Make sure all the surfaces of the teeth, including the tops of new molars, are brushed thoroughly. You might provide a timer or a two-minute song or video to make sure your child spends enough time brushing. Flossing can be tricky for young hands, so you’ll need to help with that task for a few years more.

School-Aged Children

• Dentists and orthodontists recommend a first visit to the orthodontist by age seven, or earlier if you notice your child has trouble chewing or biting, if the teeth don’t seem to fit together properly, or if you have any concerns about bite and alignment. When potential problems are discovered right away, early intervention can prevent more serious orthodontic issues from developing later. The team at Weaver Dentistry in Raleigh, NC is happy to answer any questions you might have about early interventions!
• Talk to Dr. Gregory Weaver about sealants. Permanent molars usually erupt between the ages of 6 and 12. Sealants are thin coatings which protect the chewing surfaces of these molars from food particles and cavity-causing bacteria which would otherwise collect inside grooves in the enamel.
• Children who play sports and engage in activities with a chance of physical contact should have a well-fitted mouthguard to protect their teeth. Be ready to replace it as often as recommended by Dr. Gregory Weaver or if it’s damaged.
• Increases in hormones during puberty can lead to puberty gingivitis, and swollen, red, and bleeding gums can be the result. Proactive dental hygiene will prevent gum disease from developing. Make sure your child brushes two minutes, twice a day, and flosses once per day. If symptoms persist, it’s time to see the dentist.
• If your child is beginning orthodontic treatment, you can help make the journey easier. Keep up with appointments and adjustments, look for toothbrushes and floss designed for braces, and provide braces-friendly foods. If your child wears bands or aligners, you may need to remind her to wear them for the recommended number of hours each day. 
• A nutritious diet is essential for healthy teeth and gums. Give your child solid nutritional building blocks with a diet rich in proteins, vitamins, and minerals. 

Help your child enjoy a future of healthy, confident smiles by working in partnership with your child’s dental team. They are ready every month of the year with advice and expertise to make that healthy dental future a reality!

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. Gregory Weaver at our Raleigh, NC office with any specific questions!
