If you were to put your toothbrush bristles under a high-powered microscope, what you would see might give you nightmares: millions of bacteria, busily crawling up and down your toothbrush bristles, consuming proteins that came from your mouth, and still clinging to the bristles even after you’ve rinsed them with water.

Rinsing your toothbrush after brushing removes some of those ferociously hungry bacteria, but not all. The American Dental Association says that bacterial infestations develop on toothbrushes within a month of daily use. The ADA also states that unless a toothbrush is sterilized before being packaged, it’s going to come with bacteria – free of charge!

Germs and Frayed Bristles: the Demise of a Toothbrush

Dr. Gregory Weaver and our staff recommend that you toss your old toothbrush in the trash and purchase a new one every three months. Children tend to bite on their toothbrushes, which makes the bristles degrade and fray faster. Chances are kids may need to have their toothbrushes changed more frequently.

Where do they hide?

Bacteria are tenacious little germs that head for those concealed areas between toothbrush bristles. They are highly adaptable and exist in every type of extreme environment. Some people actually go so far as to put their toothbrush in a microwave for a few seconds to kill germs, but this doesn't always work either. In fact, you may only end up with a toothbrush that’s as bendable as a Gumby doll – and still covered with germs.

Feed a Cold, Starve a Fever, and Get Rid of Your Toothbrush

When you have a head cold, your mouth is teeming with bacteria gleefully roaming around, and gobbling mucus and dead skin cells. If you brush your teeth while suffering a sinus condition, the brush will act like a magnet for ravenous bacteria. Use your old toothbrush while you are sick, but as soon as you feel better, throw it away and get a new one. Otherwise you could possibly re-infect yourself with the same cold germs!

Our grandmothers and grandfathers, our moms and dads—we’ve known them our whole lives. So, why are they so hard to shop for?

If your older family members have all the sweaters, socks, and scents they need, consider a gift that can make life a bit easier and perhaps a lot healthier—an electric toothbrush!

• Easy Efficiency

The most important reason to choose an electric toothbrush is its effectiveness. Several studies have shown that regular use of an electric toothbrush leads to a marked reduction in plaque, that bacteria-filled film which sticks to the teeth and leads to cavities and gingivitis. And it’s really no surprise that an electric brush can out-perform a manual brush.

Using a manual brush is not just a matter of applying toothpaste and scrubbing. Proper technique means short brush strokes at a 45-degree angle for the outer and inner surfaces of the tooth, thoroughly cleaning the uneven chewing surfaces of the molars, and brushing the inside of the front teeth with gentle vertical strokes. Meticulous cleaning of all these surfaces can be difficult, especially for people with dexterity issues.

Electric toothbrushes offer several options, from oscillating/rotating brushes to oscillating/rotating/pulsating models to brushes using sonic vibration technology. What they all have in common is the ability to remove plaque far more effectively than we can on our own, because they provide the equivalent of thousands and even tens of thousands of brushstrokes per minute, as opposed to the hundreds we can achieve by hand.

• Comfortable Control

An electric toothbrush can be not only more efficient, but also more comfortable for older brushers. For those with arthritis, limited mobility, injuries, or other health conditions, the larger handles can be easier to control and much more grip-friendly. And, with the work being done by the brush head, users avoid repetitive hand and wrist motion.

Also, the pressure applied to teeth and gums with an electric brush is designed to clean thoroughly while protecting the mouth. Heavy-handed manual brushing can irritate delicate gum tissue and even damage enamel over time. With an electric brush, users only need to guide it along teeth and gums as it supplies all the power needed. There are even pressure sensors available to warn users that their brushing is too vigorous.

• Apps, Anyone?

If your grandfather likes to keep things old school, a basic model with a convenient two-minute timer and several cleaning modes will offer all the bells and whistles he needs. But if your nana has more Instagram followers than you do, consider a more tech-savvy option.

Several of today’s electric brushes come with features designed to make brushing even more effective. They can let her know if she’s brushing long enough, alert her if she’s brushing too hard, and remind her that it’s time to replace the brush head. Some models link to handy apps that will map out just where she’s brushed, in case there are a few spots that get overlooked. Or choose a model which comes with a travel case that can recharge while she’s busy seeing the world.

Okay, all that being said, we’ll admit it—a toothbrush might not be the most glamorous gift your grandparent unwraps on that special day. But helping a favorite family member brush more effectively and comfortably while improving dental health? That’s a gift that keeps on giving!

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.
