Just What Is Plaque?

July 30th, 2025

From the time you were small, you’ve been warned about the dangers of plaque. Why? Because:

  • It’s an unpleasant film that sticks to your teeth
  • It causes cavities
  • It causes gum disease
  • It can cause extra problems when you wear braces

And really, do we need to know much more than this to motivate us to brush? But if you’re in a curious mood, you might be wondering just how this soft, fuzzy film accomplishes all that damage. Let’s take a closer look at the sticky problem of plaque.

How does plaque form?

We live with hundreds of species of oral bacteria, most of which are harmless, and some of which are actually beneficial. But when our oral ecosystem gets out of balance, problems can occur. For example, without regular and thorough brushing and flossing, we start to build up plaque.

Plaque starts forming within hours of your last brushing. And even though plaque fits the very definition of “seems to appear overnight,” this biofilm is actually a complex microbial community with several different stages of development.

  • It starts with saliva.

Saliva is vital to our oral health, because it keeps us hydrated, washes away food particles, neutralizes acids in the mouth, and provides minerals which keep our enamel strong. Saliva also contains proteins, which help form a healthy, protective film on the tooth surface. This film is called a pellicle.

  • Bacteria attach to the pellicle.

There are species of oral bacteria that are able to attach themselves to the pellicle film within hours of its formation. As they become more firmly attached, they begin to grow and divide to form colonies, and are known as the early colonizers of the plaque biofilm.

  • A complex biofilm forms.

If you’ve skipped brushing for a few days (please don’t!), you’ll notice a fuzzy, sometimes discolored film on your enamel—that’s a thriving plaque community, and it only takes a matter of days to go from invisible to unpleasant.

If you’re not removing plaque regularly, it can harden further and become tartar. And once you have tartar buildup, you’ll need the care of a dental professional to remove it.

  • What happens if we ignore plaque and tartar?

We get cavities and gum disease.

How does plaque cause cavities?

  • The bacteria in plaque, like all organisms, need nutrients.

Our normal oral environment and the food in our everyday diets provide the nutrients plaque needs. And, as we mentioned above, certain types of oral bacteria convert these nutrients into acids. Foods such as carbohydrates, starches, and sugars are most easily converted into acids, which is why we recommend that you enjoy them in moderation.

  • The biofilm promotes acid production.

Within the plaque film, anaerobic bacteria (bacteria which don’t use oxygen) convert sugars and starches into acids. As the plaque film becomes denser, it blocks acid-neutralizing saliva and oxygen from reaching these bacteria close to the tooth’s surface, creating an ideal environment for the bacteria to produce their acid waste products.

  • Acids attack enamel.

The sticky nature of plaque keeps these acids in contact with tooth enamel, where, over time, acids dissolve minerals in enamel, weakening the mineral structure of the tooth.

How does plaque cause gum disease?

  • Bacteria cause inflammation and gingivitis.

The bacteria in plaque irritate the delicate tissue of the gums, which causes an inflammation response which can leave your gums swollen, red, bleeding, or tender. This early form of gum disease is gingivitis. Fortunately, good dental care and careful brushing and flossing can usually prevent and even eliminate gingivitis.

  • Plaque and tartar can lead to periodontitis.

When plaque and tartar build up around and below the gumline, the gums pull away from the teeth, leaving pockets where bacteria collect, leading to infection as well as inflammation. Infections and constant inflammation not only harm gum tissue, they can destroy the bone supporting the teeth. This serious gum condition is periodontitis, and should be treated immediately to avoid further infection and even tooth loss.

How does plaque affect orthodontic patients?

  • Plaque collects around your braces.

Braces provide plenty of spots for plaque to hide from your brush. If you aren’t extremely diligent with your brushing and flossing, plaque collects near brackets, wires, and bands—all those spots that a brush and floss find difficult to reach.

  • Plaque promotes demineralization

The demineralization process we mentioned above can cause white spots on teeth (decalcification), where minerals have dissolved. Sometimes these spots can be treated, and sometimes they are permanent. They can become quite sensitive, and may lead to cavities.

Careful brushing and flossing around your braces will help eliminate the plaque that can cause demineralization near brackets. Ask Dr. Mugford about the tools and the brushing and flossing techniques which will give you the best results.

How do we fight plaque?

From the time you were small, you’ve learned how to fight plaque:

  • Brush at least twice a day for two minutes, and be sure to brush all of your tooth surfaces and around the gumline.
  • Floss to remove plaque from between the teeth and near the gumline.
  • See your dentist as recommended for a thorough professional cleaning.

Be proactive. If you have any questions, talk to us at our Halifax office about the best way to keep plaque at bay. We can show you the most effective ways to brush and floss, recommend anti-plaque toothpastes and rinses, even suggest plaque-revealing tablets if you’re missing some trouble spots.

We’ve only brushed up on some plaque basics, because there is a lot more to discover about this complex biofilm. Happily, even with all there is to learn about plaque’s growth and development, it’s reassuring to know that getting rid of it is quite simple—with just a soft-bristled brush, some dental floss, and a few minutes of your time each day, you’re on the way to a healthy, happy, plaque-free smile.

Adults and Braces

July 23rd, 2025

Nowadays, many adults are taking advantage of getting straighter teeth with braces. Dr. Mugford and our team love to help patients create the dazzling, confident smile they’ve always wanted.

Our adult patients usually fall into two categories: some had braces in the past but didn’t wear their retainers, while others are brand-new to wearing braces. Either way, both groups want the same thing: straighter teeth and a beautiful smile!

You will have several options for getting braces, depending on your financial situation and how quickly you would like your treatment to finish. Traditional metal braces are a less-expensive option and can help people who have severely crooked teeth. But many adults may not prefer this option because they dislike the appearance of metal brackets.

If you’re concerned about how you’ll look, we offer clear ceramic braces that aren’t as visible. These are more expensive than metal braces, and patients need to be careful with colored drinks that can stain them, such as coffee or red wine.

Another popular option is a clear aligner treatment called Invisalign®. This type is practically invisible; it uses a series of aligners that are customized to fit your teeth. The process of straightening your teeth can last anywhere from three to 18 months. For people who have extreme bite problems or crowded teeth, a different method may work better.

Don’t hesitate to call our Halifax office today to set up a consultation. Dr. Mugford will help you choose the best option so you can be on your way to a straighter, more confident smile!

Orthodontics and Oral Piercings

July 16th, 2025

Traditional braces and oral piercings—does the inevitable meeting of metals pose any risks? Let’s look at some of the potential problems with oral piercings, and you and Dr. Mugford can decide if you should take a break from jewelry while you’re in treatment.

  • Tooth Damage

Enamel is the strongest substance in our bodies, but when up against constant contact with metal? It’s not a fair fight.

Tongue piercings, especially, cause problems for your teeth. Whenever you speak or eat—even while you’re sleeping!—your tongue is making contact with your teeth. This continual tapping of metal on enamel can chip and crack teeth and damage fillings. A serious fracture could mean a root canal.

You’re getting braces to create a more attractive, healthy smile, so keeping your teeth intact is a priority.

  • Gum Problems

Your gums are affected by orthodontic treatment. As the teeth move, the gums, ligaments, and bone around them adapt and even reshape over time. You might notice when you first get your braces, or when you go in for an adjustment, that you have a few days of swollen, sensitive gums afterward. You might also find that you are at greater risk of gingivitis, because it can be harder to keep plaque away from your gumline until you perfect your brushing and flossing skills.

Oral piercings bring their own gingival dangers. Jewelry in the tongue or lip can rub against gum tissue, especially around your lower front teeth. As the gum tissue continues to be irritated and inflamed, it pulls away from the teeth. This process is called gum recession.

Receding gums expose the tops of your roots to cavity-causing bacteria. They make you more sensitive to hot or cold foods. Pockets between gums and teeth can harbor infections that threaten the tooth itself.

Caring for your gums during braces is important for your dental health. Since people with oral piercings have a much higher rate of gum recession that those without, why add one more risk factor to your oral health?

  • Metal vs Metal

Lip and tongue piercings can make contact with traditional brackets and wires, especially if you have a habit of playing with them. And let’s not forget lingual braces! Lingual braces are almost invisible because their brackets and wires are custom fitted to the back of your teeth. Whenever you speak or eat, you’ll be taking the chance that a tongue piercing will damage these custom-made appliances.

Dr. Mugford can tell you if your piercings are in any danger of interfering with your braces, but even if you’re planning on aligners, there are additional reasons to consider retiring your oral jewelry. Dental associations and medical associations discourage oral piercings because they can damage teeth and gums. And there’s more. Oral piercings can lead to swelling, bleeding, allergic reactions, infection, and nerve damage.

The reason you’re considering braces is because you want a healthy, attractive smile. Don’t let a tiny piece of jewelry make your life and your treatment more difficult! Do some research and talk to our Halifax team about your oral piercings, and come up with a solution that’s best for your health and best for your smile.

When should I floss during the day?

July 9th, 2025

A vital step in your oral health routine is flossing. We hope our patients at Metro Orthodontic Specialists maintain good oral hygiene, including daily flossing between each visit to our Halifax office. A toothbrush is not always enough to get to the hard-to-reach areas of your mouth. When food remains between your teeth, bacteria starts to grow and will break down your enamel. This is where flossing comes in!

Should you floss before or after brushing?

Whatever your personal preference, you may floss before or after you brush your teeth. When you floss first, you can brush away any leftover dislodged food debris from your teeth. On the other hand, when you brush first, you will loosen the plaque between your teeth, which makes flossing more effective.

The essential aspect is that you floss thoroughly by using a fresh strand of floss and make sure to get between every tooth. Even if your teeth look and feel clean, don’t skip flossing or plaque will begin to build up on your teeth.

When is the best time to floss?

Although you should brush your teeth at least twice a day, Dr. Mugford and our team recommend flossing your teeth thoroughly once a day. Many people prefer to floss before bed, so that plaque doesn’t sit between their teeth all night.

What kind of floss should I use?

You may choose between interdental cleaning picks or flexible floss strands to perform your daily flossing routine. If you have permanent oral appliances or restorations, be sure to follow the flossing instructions provided to you.

Do you need help flossing?

If you’re having trouble flossing or have questions about which floss is best for your teeth, contact our Halifax office and we can provide you with support. Be sure to keep up with your daily flossing routine, and we will see you at your next appointment!
