While we often associate tooth decay with cavities forming in a tooth’s visible or biting surfaces, the occurrence of this all too common disease isn’t limited to those areas. Cavities can develop in any part of a tooth exposed to bacteria.
Gum recession, the shrinking back of the gums from the teeth, can cause such exposure in areas normally covered by the gums. Because these areas are usually more vulnerable to infection when exposed, cavities can develop at or right below the gum line. Because of their location it can be difficult to fill them or perform other treatments.
One way to make it less difficult is to perform a crown lengthening procedure. While the term sounds like we’re increasing the size of the tooth, we’re actually surgically altering the gums to access more of the affected tooth surface for treatment. It’s typically performed in a dental office with local anesthesia by a general dentist or a periodontist, a specialist in the gums.
During the procedure, the dentist starts by making small incisions in the gums to create a tissue “flap” that can be lifted out of the way. This exposes the underlying bone, which they then reshape to support the gum tissue once it’s re-situated in its new position. The dentist then sutures the gums back in place. Once the gums heal, the decayed area is ready for treatment.
Crown lengthening is also useful for other situations besides treating cavities. If a tooth has broken off at the gum line, for example, there may not be enough remaining structure to support a crown. Crown lengthening can make more of the underlying tooth available for the crown to “grab” onto. It’s also useful in some cases of “gummy smiles,” in which too much of the gum tissue is visible in proportion to the tooth size.
Because crown lengthening often involves removing some of the bone and is thus irreversible, you should discuss this procedure with your dentist in depth beforehand. It could be, though, this minor procedure might make it easier to preserve your teeth and even make them look more attractive.
In 2016, voters in three states—California, Massachusetts and Nevada—joined Alaska, Colorado, Oregon, Washington and the District of Columbia in legalizing the use of recreational marijuana. These referenda moved the country closer to what may soon be a monumental political showdown between the states and the federal government, which still categorizes marijuana as a controlled substance.
But there’s another angle to this story often overshadowed by the political jousting: is increased marijuana use a good thing for your health and overall physical well-being?
When it comes to your dental health, the answer might be no. The Journal of Periodontology recently published a study that included frequent marijuana users showing increased signs of periodontal (gum) disease. This harmful bacterial infection triggered by plaque buildup can cause weakening of gum attachment to teeth and create the formation of large voids between teeth and gums called periodontal pockets. Left untreated, the disease can also cause supporting bone loss and eventually tooth loss.
The study looked at the dental treatment data of over 1,900 adults of which around one-quarter used marijuana once a month for at least a year. Marijuana users in the study on average had 24.5% of pocket sites around their teeth with depths of at least eight millimeters (an indication of advanced gum disease). In contrast, non-users averaged around 18.9% sites.
To be sure, there are several risk factors for gum disease like genetics, oral hygiene (or lack thereof), structural problems like poor tooth position or even systemic conditions elsewhere in the body. This published study only poses the possibility that marijuana use could be a risk factor for gum disease that should be taken seriously. It’s worth asking the question of whether using marijuana may not be good for your teeth and gums.
When is the best time to floss your teeth: Morning? Bedtime? How about: whenever and wherever the moment feels right?
For Cam Newton, award-winning NFL quarterback for the Carolina Panthers, the answer is clearly the latter. During the third quarter of the 2016 season-opener between his team and the Denver Broncos, TV cameras focused on Newton as he sat on the bench. The 2015 MVP was clearly seen stretching a string of dental floss between his index fingers and taking care of some dental hygiene business… and thereby creating a minor storm on the internet.
Inappropriate? We don't think so. As dentists, we're always happy when someone comes along to remind people how important it is to floss. And when that person has a million-dollar smile like Cam Newton's — so much the better.
Of course, there has been a lot of discussion lately about flossing. News outlets have gleefully reported that there's a lack of hard evidence at present to show that flossing is effective. But we would like to point out that, as the saying goes, “Absence of evidence is not evidence of absence.” There are a number of reasons why health care organizations like the American Dental Association (ADA) still firmly recommend daily flossing. Here are a few:
- It's well established that when plaque is allowed to build up on teeth, tooth decay and gum disease are bound to follow.
- A tooth brush does a good job of cleaning most tooth surfaces, but it can't reach into spaces between teeth.
- Cleaning between teeth (interdental cleaning) has been shown to remove plaque and food debris from these hard-to-reach spaces.
- Dental floss isn't the only method for interdental cleaning… but it is recognized by dentists as the best way, and is an excellent method for doing this at home — or anywhere else!
Whether you use dental floss or another type of interdental cleaner is up to you. But the ADA stands by its recommendations for maintaining good oral health: Brush twice a day for two minutes with fluoride toothpaste; visit your dentist regularly for professional cleanings and checkups; and clean between teeth once a day with an interdental cleaner like floss. It doesn't matter if you do it in your own home, or on the sidelines of an NFL game… as long as you do it!
Dental implants are best known as restorations for single missing teeth. But there’s more to them than that—they can also be used to support and secure removable dentures or fixed bridges.
That’s because a dental implant is actually a root replacement. A threaded titanium post is inserted directly into the jawbone where, over time, bone cells grow and adhere to it. This accumulated bone growth gives the implant its signature durability and contributes to its long-term success rate (95%-plus after ten years). It can support a single attached crown, or serve as an attachment point for a dental bridge or a connector for a removable denture.
The method and design of implants differentiates it from other restoration options. And there’s one other difference—implants require a minor surgical procedure to insert them into the jawbone.
While this might give you pause, implant surgery is no more complicated than a surgical tooth extraction. In most cases we can perform the procedure using local anesthesia (you’ll be awake the entire time) coupled with sedatives (if you have bouts of anxiety) to help you relax.
We first access the bone through small incisions in the gums and then create a small channel or hole in it. A surgical guide that fits over the teeth may be used to help pinpoint the exact location for the implant.
We then use a drilling sequence to progressively increase the size of the channel until it matches the implant size and shape. We’re then ready to insert the implant, which we remove at this time from its sterile packaging. We may then take a few x-rays to ensure the implant is in the right position, followed by closing the gums with sutures.
There may be a little discomfort for that day, but most patients can manage it with over-the-counter pain relievers like aspirin or ibuprofen. It’s what goes on over the next few weeks that’s of prime importance as the bone grows and adheres to the implant. Once they’re fully integrated, we’re ready to move to the next step of affixing your crown, bridge or denture to gain what you’ve waited so long for—your new implant-supported smile.

Oral hygiene maintains healthy teeth and gums. Really, it's the mainstay of preventive dentistry, and it starts with you, the dental patient. At Ajax Dental Centre, Dr. Saeid Jafarpour, Dr. Kevin Kwong, and Dr. Azza Elhaddad, your Ajax, ON, dentists, want you to understand what good oral hygiene habits are so you have a smile that lasts and looks great.
Brushing and flossing
You know they're important, but are you doing them correctly? Well, the Canadian Dental Association (CDA) says that brushing twice a day for two minutes is the minimum. Choose a soft-bristled brush, and use a fluoride toothpaste with the CDA Seal for best results. Floss once a day with the product that suits you best. Strand floss, Y-flossers, interproximal brushes and water flossers are popular choices. Most people floss at bedtime.
What's the point of these tried and true hygiene practices? Both combat bad breath and dental stains. Additionally, they remove soft, sticky plaque formed from carbohydrate-based food residues. Left alone, plaque hardens into tartar, or calculus. Both plaque and tartar contain oral bacteria which actively secrete corrosive acids, the bottom-line cause of tooth decay, gum disease and ultimately, tooth loss.
What's in your mouth?
Yes, what you eat and drink are part of oral hygiene. Be sure to limit processed sugars, and increase your water intake. Reduce between-meal snacking, and if you smoke, please see your primary care physician for a tobacco cessation program. Cigarettes and smokeless tobacco contain dangerous toxins which degrade tooth enamel, gum tissue, and underlying bone. Plus, both increase the incidence of oral cancer, says the American Cancer Society.
At Ajax Dental Centre, your professional team asks to see you semi-annually for your oral examination and hygienic cleaning. During your cleaning, your hygienist will scale your teeth to remove any plaque and tartar you miss with your home hygiene. Also, she'll polish your teeth with a rotary brush and mildly abrasive toothpaste.
Finally, your hygienist and your Ajax dentist will tell you ways to improve your home care. They may suggest a new floss, show you where you should clean your teeth more carefully or demonstrate the best way to brush your new porcelain veneers or crown.
Your good oral hygiene pays big dividends. Dr. Jafarpour, Dr. Kwong, and Dr. Elhaddad look forward to helping you keep a sparkling, healthy smile for life. Call Ajax Dental Centre today for your routine cleaning and exam: (905) 426-8304.
