Let’s talk science! From the vastness of the cosmos to sub-atomic particles, science helps us understand the world around us and how it works. So, let’s take some familiar scientific fields of study and apply them to your toothbrush.

My toothbrush?

Yes, indeed! When it comes to your oral health, your toothbrush is the first line of defense, so understanding how and why it works so well might help us use this handy tool even more effectively.

Biology—the study of living organisms

Unfortunately for your toothbrush, the living organisms we’re talking about here are the bacteria which cause tooth decay and those which can lead to illness. How do these problems arise, and how do we prevent them?

Fight Plaque

Plaque is the sticky film that builds up on teeth, and millions of oral bacteria help make up this biofilm. These bacteria convert sugars and other carbohydrates in the foods we eat into acids. And these acids erode our tooth enamel, leading to tooth decay. (More on this when we get to Chemistry.) The best ways to get rid of plaque?

• Brush often. The recommended minimum is two minutes of brushing twice a day, but when you’re having orthodontic work done, it’s even more important to banish the plaque that can stick to your braces or inside aligners. Ask us what brushing schedule is best for you.
• Try an electric toothbrush. For some people with braces, cleaning the teeth is easier and more thorough with an electric brush.
• Replace your brush regularly. Brushes become worn and frayed after three or four months, and you won’t be brushing as effectively.

Stop Germs from Spreading

• Don’t share. Sharing toothbrushes can lead to an increased risk of colds and infections.
• Rinse thoroughly after brushing, making sure you remove any toothpaste or debris left after you brush.
• Store the brush upright and let it air-dry. Covering the brush or keeping it in a closed container can promote the growth of bacteria more easily.
• Keep different brushes separate when they’re drying to avoid cross-contamination.
• Replace your brush regularly!

Chemistry—the study of what makes up substances, their properties, and how they interact

When it comes to improving your brushing chemistry, the best thing you can do for your toothbrush is to put a dab of fluoride toothpaste on it! Why fluoride? Let’s look at the chemistry of tooth enamel.

Tooth enamel is the strongest substance in our bodies—even stronger than bone. But it is not indestructible, and acidic substances can dissolve the mineral bonds which give our enamel its strength, whether they come from the bacteria in plaque or are found in our favorite foods and drinks (sodas, coffee, tomatoes, and citrus are among the tasty, but acidic, culprits).

The enamel in our teeth contains calcium and phosphate ions, minerals which help make it the strongest substance in our bodies. But when the level of acidity in our mouths becomes too high, these minerals begin to dissolve. Eventually, teeth become pitted, bacteria can penetrate more deeply, and decay is the result.

So what can we do? While our saliva helps neutralize acidity naturally, and we can cut back on acidic foods in our diets, using fluoride toothpaste actually helps restore the strength of our enamel in a process known as “remineralization.”

Fluoride works on the surface of enamel to both attract and anchor calcium ions, reducing mineral loss and strengthening the weakened enamel. Fluoride also interacts with the calcium and phosphate compound to create a new compound that is even stronger and more acid-resistant.

When you brush with fluoride toothpaste, you help replace and restore the mineral composition of your enamel—and there’s evidence that fluoride might even interfere with oral bacteria’s ability to produce acid. Now that’s good chemistry!

Physics—the study of matter and energy and their interactions

The matter here is your tooth enamel, and the energy is the force you use when brushing. And this is one time the force should not be with you.

• Over-vigorous brushing can not only damage your brackets, but can also irritate delicate gum tissue and wear down enamel. A “sawing” back-and-forth motion is both hard on your enamel and misses plaque and debris between the teeth. We’ll be happy to show you the safest and most effective way to brush with braces. Just remember, “Massage, don’t scrub.”
• A soft toothbrush is almost always your best option when you use a manual brush, but if you’re still a heavy-handed brusher, or have sensitive teeth and gums, consider an electric model. An electric toothbrush should provide a continuous brushing motion without needing any heavy pressure from the brusher. Some models will even let you know when you are brushing too hard.

Brushing harder is not brushing better, and your teeth, gums, and braces will be heathier with careful brushing habits. If you need tips on brushing with braces, contact our Hampstead, NC and Jacksonville, NC office and ask!

There’s a lot of science in the simple act of brushing, but we don’t need to spend hours studying to get a passing grade in dental health. The things you do normally—brushing at least two minutes twice a day, using fluoride toothpaste, and applying proper brushing technique—will help create a smile which will earn you top marks from Dr. Kevin Mancini for a lifetime!

Brackets and wires, clear aligners, lingual braces, regular brackets, self-ligating braces, elastics, spacers—you and your orthodontist have had to narrow down a lot of choices to discover the best treatment for your orthodontic needs. Now that the end of treatment is in sight, there’s one more important choice left—your retainer!

Do I Need a Retainer?

No retainer at all is probably the one option that’s off the table from the start. It’s not just your teeth that have changed position; it’s the bone and ligaments holding them that have changed as well.

A retainer prevents your teeth from moving away from their new, ideal location while your bones and ligaments are stabilizing. This process takes months, so keeping your teeth in place as your bone rebuilds and regains density is crucial.

What Are Your Retainer Options?

Three of the most popular retainer options available at our Hampstead, NC and Jacksonville, NC office include:

• Hawley Retainers

This is the traditional retainer, with wires to hold your retainer in place and to keep the teeth properly aligned. The wires are attached to an acrylic plate molded to fit the roof of your mouth or around your bottom teeth. You can customize the acrylic base with colors and patterns for a one-of-a-kind look.

Hawley retainers are adjustable, so minor realignments can take place if necessary. The wire in front of your teeth makes these retainers visible, but, after several months of wearing them all day long, you may end up wearing them only at night.

Hawley retainers are removable, so you need to make sure they are safely in a case when you’re not wearing them. Minor damage can often be repaired, but it’s better to be proactive.

• Clear Plastic Retainers

These retainers look like clear aligners. They are formed by heating a thin piece of plastic and vacuum-forming it around a model of your teeth to create a custom, comfortable fit.

Clear retainers are almost invisible when worn, and can be removed when you eat or drink—which they should be, because food particles and liquids can be trapped inside them.

When you’re not wearing it, a clear retainer should always be in its case, because it must be replaced if the plastic is warped, cracked, or broken.

• Fixed Retainers

A fixed retainer is a small single wire bonded to the back of specific teeth, commonly the six bottom front teeth. Because fixed retainers don’t allow the teeth to move at all, they are often recommended for patients who had serious misalignments, extremely crowded teeth, or teeth with large gaps between them.

Many patients like fixed retainers because they keep teeth in perfect alignment, they won’t be seen, they’re comfortably small, and they can’t end up in the cafeteria recycling bin because you forget to replace them after lunch!

Fixed retainers are usually quite durable, but you’ll need to pay attention to your diet, because crunchy and chewy foods can put pressure on the retainer and damage it. These retainers also require special care with brushing and flossing, to make sure the teeth bonded to the wire stay clean and plaque-free.

The Right Retainer

The process of stabilizing your teeth in the jaw takes time. Choosing your retainer will depend in part on how long and how often you need to wear it: fulltime for months or for years, at night after several months of day-and-night wear, or long-term to make sure your orthodontic work lasts.

And there are other variables, as well. Your retainer might need to be removable. It might need to be adjustable. You might need a retainer for just your upper teeth, just your lower teeth, or both. All these factors and more need to be taken into consideration before deciding on your ideal retainer.

Fixed, removable, wire, plastic, colorful, clear—which retainer is right for you? The one that helps you retain the beautiful smile you’ve worked for all these months. Talk to Dr. Kevin Mancini to discover the retainer that will protect that smile for years to come.

As we start our summer, our team at Mancini Orthodontics wants to remind our patients who have completed treatment that it is very important to wear your retainer as prescribed even while away for vacations and summer camps.

If you are away from home and only wearing your retainer at night, here is a helpful tip: after removing and brushing your retainer in the morning, place it back in the case and then put it with your PJ’s or on your pillow. That way you have a reminder to put your retainer back in at night.

Remember, retainers should be worn every night, not just some nights.

We wish you safe travels and adventures this summer!
