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 Stoney Creek 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. Nicola Crichigno for a lifetime!

We’ve probably all seen that unhappy kid or frazzled parent sifting through trash for a lost retainer. If we’re really unlucky, we might have been that unhappy kid or frazzled parent sifting through the unpleasant remains of third period lunch hour. But getting tossed isn’t the only risk these appliances face. Read on for ways to keep your retainer (and your parent!) happy.

• Keep Your Retainer With You

Always carry a retainer case. If you automatically put your retainer in its case when you’re eating, you are much more likely to remember it then if it has been wrapped up in a napkin on your lunch tray. And, if the worst happens, much more likely to recover it in one piece.

Choose the brightest colored case you can live with, so you will have an easier time locating it if need be, and discuss how to label the case to get it back safely to you--just in case.

• Keep Your Retainer Intact

You might think if you put your retainer in your backpack, or purse, or saxophone case, or athletic bag, it will be safe. It will not. Retainers are designed to be tough enough for everyday wear, but being tossed on the floor while inside a backpack is not everyday wear. Always put your retainer back in its (brightly colored) case before packing it away.

Retainers can warp if they are exposed to heat, so keep them away from potential heat sources like stoves, microwaves, and washers and dryers. Even your car dashboard can become hot enough to warp your retainer. And never use boiling water to clean them.

Finally, your dog might find your retainer to be the #bestchewtoyever, so be sure to put it in a spot pets can’t reach when you’re not wearing it.

• Keep Your Retainer Clean

Just like plaque can build up on your teeth, minerals and calcium can build up on your retainer. Different types of retainers require different cleaning methods, so talk to Dr. Nicola Crichigno about how to keep your retainer clean and bacteria-free. We will be happy to give you instructions on the best way to take care of your particular appliance. And don’t forget to clean your case regularly!

Accidents will happen, of course. If your retainer is lost or damaged, call our Stoney Creek office as soon as possible. We might be able to fix minor damage, and, if needed, we can replace a lost retainer quickly.

Your time in braces is over, but your teeth are still stabilizing in their new, healthy positions. Wearing your retainer regularly is the final step in producing the beautiful smile you’ve worked so hard for. Keep your retainer clean, keep it safe, and keep it with you, and you can enjoy that smile now and for years to come!

X-rays have been a function of dental healthcare for a long time. That in and of itself should be good news, because it means we've had plenty of time to improve them. While there is always some risk in exposure to radiation, dental X-ray exposure has decreased significantly due to all the advances in technology. So there’s risk, but X-rays are quite safe.

Think of X-rays as you would about a car. Automobiles these days have all kinds of technology to make them as safe as possible. There's still a chance that you’ll suffer an accident. Would you stop using a car because of that risk? When it comes to dental X-rays, Dr. Nicola Crichigno and our team believe the positives clearly outweigh the negatives.

X-rays can be done digitally or with film. For film, X-rays require different exposures at different speeds to produce the image. Digital X-rays have software that automatically adjusts the exposure and produces the X-ray in a digital file. Since they substantially reduce your exposure to radiation, digital X-rays are the current standard in dental offices.

In addition to digital X-rays, lead aprons are an essential piece of X-ray safety. They help protect internal organs from X-rays by acting as a shield. They usually come with a thyroid collar as well, since that is one of the most vulnerable areas to X-rays in the body. Lead aprons can absorb up to 95% of any scatter rays that result from an X-ray. Not bad, right?

Although dental X-rays involve some radiation exposure (not all of it can be eliminated), so does everyday life. Getting too much sun, for example, can be dangerous. The truth is, we accumulate radiation in our bodies over a lifetime, so it’s worthwhile to be aware and avoid as much unnecessary exposure as possible. When it comes to your dental health, though, getting an X-ray — especially when your doctor says you need it — offers more benefits than risks.

The dental procedures that focus on the correction of alignment and bite are known as orthodontic care. With the aid of braces, aligners, retainers, brackets, and similar appliances, orthodontic treatment can correct oral disorders such as protruding teeth, crowding, difficulty biting or chewing, and speech issues. Seeking orthodontic treatment at Crichigno Orthodontics can drastically improve your oral appearance, comfort, and health, while also encouraging proper oral hygiene and enhanced self-esteem. Both growing children and adults with oral alignment issues can benefit greatly from completing customized orthodontic treatment with Dr. Nicola Crichigno.

Due to the uniqueness of each mouth and the severity of each malocclusion disorder, there is no one set timeframe for orthodontic treatment. The length of your treatment is determined by many factors, including the severity of your alignment issue, your age, the health of your teeth, and the specific orthodontic procedure you need to undergo. Nevertheless, typical treatment usually takes between 12 and 36 months.

Avoiding alignment issues

While some alignment issues are brought on by unavoidable matters such as accidents, genetics, and physical disorders, some issues arise out of certain actions you should not be doing. Finger sucking and improper oral hygiene are the two most common self-inflicted reasons for alignment issues. Constant finger sucking can alter the pattern in which your teeth grow, which in turn may cause bite issues. Improper oral hygiene such as infrequent dental visits and improper brushing and flossing can lead to decay and loss of teeth, which will interfere with the bite in your mouth.

To avoid advanced alignment issues, it is important to establish a relationship with a quality dentist when you’re young and seek orthodontic treatment at the first sign of alignment problems to encourage healthy and straight teeth for a lifetime.
