Why do you chew gum? Perhaps because it’s a habit that comes with some healthy benefits. Chewing a stick or two reduces the urge to snack between meals. It’s a substitute for behaviors like nail biting that you’d like to change. It might even give you fresher breath after those tuna sandwiches in the cafeteria.

And, as it happens, chewing sugarless gum actually offers a few dental benefits as well! The act of chewing increases saliva production. Saliva washes away food particles, neutralizes acids in the mouth that can damage enamel, and even bathes the teeth in essential minerals that help strengthen weakened enamel. We’re talking about sugar-free gum here, of course, because regular gum will just bathe your teeth in sugar—no one’s idea of a dental benefit!

So why not open that pack and enjoy? Because, despite the many positive reasons you can think of for chewing gum, sometimes gum can have a negative impact on your braces.

• A Sticky Situation

Keeping your braces clean can be a bit of a challenge. That’s why you have special toothbrushes, flosses, and interproximal brushes to get rid of food particles that stick around after you eat. And, while any food can get caught in your braces, sugared gum, because it is so sticky, can stick to appliances much more easily and much more thoroughly than even sugar-free gum. You might be able to remove gum residue with regular brushing and flossing, but, worst case scenario, you might be looking at gum firmly stuck in the brackets or between the brackets and wires.

• Gumming Up the Works

Chewing gum can also affect your treatment time if the action of chewing causes your arch wire to bend. When your wire isn’t providing the proper shape or the right amount of tension, your teeth won’t get to where they need to be as quickly and efficiently. No piece of gum is worth discovering at your next appointment that you haven’t made any progress for weeks due to a damaged wire. And since chewing gum can also lead to loose brackets and bands, you might wonder if this sticky habit is ever worth the trouble it can cause.

• Something to Chew Over

Before you decide, talk to Dr. Razavi! Chewing sugarless gum increases saliva production, which can help wash away food particles from your mouth and your braces. As an added benefit, the action of chewing for a few minutes after an appointment has been shown to reduce the discomfort of an adjustment. Because today’s braces are stronger and more durable, and sugarless gum much less likely to stick to them, we can let you know if chewing gum might be acceptable or even desirable depending on your specific treatment plan and your appliance.

Talk to us at your next appointment at our Kanata, Ontario office about gum chewing, and we’ll give you the very best recommendations for keeping your teeth healthy, your braces clean, your appliance intact, and your treatment plan on track. Even if gum needs to be off the menu for a while, what you’ll get in return—the best and fastest path to your beautiful smile—will be well worth it!

When does an underbite need surgery? The short answer is: when Dr. Razavi and our team recommend surgery as the best way to give you a healthy, functional bite. But let’s take a longer look, and see just why your doctors might come to that conclusion.

• First, what exactly is an underbite?

In a perfect bite, the upper and lower jaws align, well, perfectly. Upper teeth overlap lower teeth very slightly, upper and lower teeth meet comfortably, and jawbones and joints function smoothly. When the alignment is off, it causes a malocclusion, or “bad bite.”

When we talk about an underbite, or Class 3 malocclusion, it means that the lower jaw protrudes further than the upper jaw. This protrusion causes the bottom teeth and jaw to overlap the upper teeth and jaw.

• What causes an underbite?

Sometimes an underbite is caused by childhood behaviors while the teeth and jaw are developing, including tongue thrusting or prolonged thumb-sucking and pacifier use. (Working to stop these behaviors before they affect tooth and jaw formation is one of the many good reasons children should have regular visits with their dentists and pediatricians.)

Most underbites are genetic, however, and tend to run in families. It’s estimated that from five to ten percent of the population has some form of underbite. The lower jawbone (mandible) might be overdeveloped, the upper jawbone (maxilla) might be underdeveloped, both bones could be affected, or, sometimes, tooth size and placement might cause an underbite. These irregularities in jaw shape and size and/or tooth crowding are not something that can be prevented, and require professional treatment.

• Why? What’s the problem with an underbite?

Even a minor underbite can cause difficulties with biting and chewing. A more severe underbite can lead to speech problems, decay and loss of enamel where the teeth overlap, mouth breathing and sleep apnea, persistent jaw and temporomandibular joint pain, and self-confidence issues.

• Can’t my dentist treat my underbite?

Most probably not. A very mild underbite can be camouflaged cosmetically with veneers, but this does not address the cause of the underbite, and will not work for moderate or severe underbites.

• Can my orthodontist treat my underbite?

Dr. Razavi will create an underbite treatment plan after a detailed study of each patient’s individual dental and skeletal structure. Treatment options will vary depending on the cause of the underbite, its severity, and even the patient’s age.

Early intervention is especially important for children who show signs of an underbite. That’s why we recommend that children visit our Kanata, Ontario office by the age of seven.

If an underbite is caused by tooth misalignment or crowding, braces can reposition the lower teeth. Sometimes extractions are necessary to make room for proper alignment.

If the cause is due to jaw structure, children’s bones are still forming, so treatment can actually help correct bone development. Palatal expanders, headgear, and other appliances are various methods of encouraging and guiding bone development.

But braces and appliances aren’t effective for every patient with an underbite, and especially in patients (usually those in their late teens and older) when the jawbones are already fully formed. In this case, we might suggest coordinating treatment with an oral and maxillofacial surgeon.

• What does an oral and maxillofacial surgeon do?

An oral surgeon has the training, experience, and skill to help correct an underbite by surgically reshaping and repositioning the jawbone. This corrective jaw surgery is called orthognathic surgery.

• What will happen during orthognathic surgery?

Your treatment will be tailored to your specific needs. Two of the common surgical procedures for treating an underbite involve repositioning the upper jaw to lengthen it and/or reshaping the lower jaw to shorten it.

Bone is sometimes removed or added, small bone plates or screws are sometimes used to stabilize the bone after surgery—your surgeon will let you know exactly which procedures will give you a healthy, functional bite. The surgery itself is most often performed under general anesthesia and requires a brief stay in the hospital.

• How will my orthodontist and oral surgeon coordinate my treatment?

Correcting a Class 3 malocclusion can take time. Your oral surgeon will work together with Dr. Razavi to analyze the interrelationship of teeth, bones, and joints to determine dental and skeletal problems, and will develop the best treatment plan possible to create a healthy alignment.

• So, when does an underbite need surgery?

Sometimes, a minor underbite can be corrected with braces and appliances alone. A serious underbite, however, will often require the specialized skills of both Dr. Razavi and an oral surgeon.

And, while it’s not the primary purpose of surgery, corrective jaw surgery and orthodontics can also make you happier with your appearance and boost your self-confidence. Achieving a lifetime of beautiful, comfortable, and healthy smiles—that’s the answer to your question.

By now, everyone knows that smoking is bad for you. But the truth is its broad-reaching health effects are not all known by everyone. This is especially true of oral health. Smoking can have serious repercussions in this regard. To give you a better idea of how smoking can affect your oral health, Dr. Razavi and our team have listed some issues that can arise.

Oral Cancer

Oral cancer can have steep ramifications for anyone that gets it. Surgery can be required to eliminate the cancer before it spreads to more vital parts of your body. Any type of cancer is about the worst health effect you can get, and this especially holds true to the affects that smoking has on your mouth. The type of mouth surgery required with oral cancer can leave your face deconstructed in certain areas, and it is all due to smoking or use of other tobacco products.

Tooth Discoloration and Bad Breath

At the very least, it is fair to say that as a smoker you will often have bad breath, and while you may try to cover it up with gum or mints, tooth discoloration is a whole other story. The chemicals and substances in cigarettes stick to your teeth staining them brown and yellow colors that are increasingly difficult to disguise.

Gum Disease and Loss of Bone

Another effect of smoking is the increased risk of gum disease. Your gums may start to recede, which can eventually lead to the loss of teeth. Smoking can also increase bone loss and density in your jaw which is vital to the health of your mouth. Gum disease and bone loss are two signs that smoking is definitely bad for your mouth.

When it comes to the health of your mouth, the question is not whether smoking affects your health, it's how does it affect your health and to what degree. If for no other reason than because smoking involves your mouth as its entry point, it is safe to say that it can have long-lasting and detrimental consequences on your oral health.

By no stretch is it rare for your gums to hurt during and after flossing. Even some bleeding is to be expected. This is especially true if you have not flossed in a long time. However, if your gums do indeed hurt when you floss, and unbearably so, there are some things you can do.

Be Gentle

Perhaps the most obvious way to combat gum soreness and bleeding is to be gentle. One of the most common occurrences of these gum problems is over-aggressive flossing. In other words, if you are too rough on your gums while flossing, either because you are out of practice or because you are in a hurry, soreness and hurting is to be expected. Instead, try taking your time and be gentle. Also, if you are just starting out, be patient and consistent, your gums will become more conditioned over time.

Use an Alternative Method

If being consistent and gentle does not work, there are other alternative methods of flossing that you can try. You can also try a water floss machine, or what is sometimes called a water pick. The device essentially shoots water into the crevasses between your teeth, and in other areas of your mouth, in order to dislodge food and plaque. These oral instruments also come with different attachments that allow you to reach many of the hard to see and reach areas of your mouth. And lastly, you can always buy floss that is not as abrasive to your gums. There is floss that comes with soft and gentle coatings that will do less harm to your gums while they are adjusting to the good oral hygiene habit you are creating.

Flossing is one of the easiest parts of oral hygiene to overlook. When you first start out, it is common that you may want to stop because of the pain it can initially cause. However, if you try one, or all, of the above mentioned methods, you will give yourself the best chance of being success with your flossing, and it won't hurt as much.
