Many people have questions about the proper use of antibiotics — especially today, as the overuse of these medications has become a concern. It isn’t necessary for most people to take antibiotics before having a dental procedure. But for a few — notably, those with particular heart conditions and, in some cases, joint replacements — pre-medication is advisable. The question may be even more confusing now, because the standard recommendations have recently changed — so let’s try and sort things out.
First, why would anyone need antibiotics before dental treatment? Essentially, it’s because of the chance that an open wound could allow bacteria from the mouth to enter the bloodstream. For people in good health, the body is capable of quickly containing and neutralizing the bacterial exposure. But people with some types of heart disease, heart transplants, and/or total joint replacements have a greater likelihood of developing a bacterial infection, which can be dangerous — or even life-threatening. The same may be true of people whose immune systems are compromised.
At one time, people with a broad range of heart problems and artificial joints were advised to pre-medicate; today, new research indicates that fewer people need to take this step. Antibiotics are currently recommended before dental procedures if you have:
- An artificial heart valve, or a heart valve repaired with artificial material
- A history of endocarditis
- A heart transplant with abnormal heart valve function
- Cyanotic congenital heart disease (a birth defect where blood oxygen levels are lower than normal) that hasn’t been fully repaired — including children with surgical shunts and conduits
- A congenital heart defect that has been completely repaired with artificial material or with a device — but only for the first six months after the repair procedure
- Repaired congenital heart disease with residual defects, such as leakage or abnormal flow
In addition, not everyone who has an artificial joint needs antibiotic premedication. Instead, your health care providers will rely on your individual medical history to determine whether this step is required in your situation. However, having a compromised immune system (due to diabetes, cancer, arthritis, chemotherapy and other factors) is still an indication that antibiotics may be needed.
The question of whether or not to pre-medicate is an important one — so it’s vital that you share all relevant medical information with your doctors and dentists, and make sure everyone is in the loop. That way, the best decisions can be made regarding your treatment.
On the big screen, Australian-born actress Margot Robbie may be best known for playing devil-may-care anti-heroes—like Suicide Squad member Harley Quinn and notorious figure skater Tonya Harding. But recently, a discussion of her role in Peter Rabbit proved that in real life, she’s making healthier choices. When asked whether it was hard to voice a character with a speech impediment, she revealed that she wears retainers in her mouth at night, which gives her a noticeable lisp.
“I actually have two retainers,” she explained, “one for my bottom teeth which is for grinding my teeth, and one for my top teeth which is just so my teeth don't move.”
Clearly Robbie is serious about protecting her dazzling smile. And she has good reasons for wearing both of those retainers. So first, let’s talk about retainers for teeth grinding.
Also called bruxism, teeth grinding affects around 10 percent of adults at one time or another, and is often associated with stress. If you wake up with headaches, sore teeth or irritated gums, or your sleeping partner complains of grinding noises at night, you may be suffering from nighttime teeth grinding without even being aware of it.
A type of retainer called an occlusal guard is frequently recommended to alleviate the symptoms of bruxism. Typically made of plastic, this appliance fits comfortably over your teeth and prevents them from being damaged when they rub against each other. In combination with stress reduction techniques and other conservative treatments, it’s often the best way to manage teeth grinding.
Orthodontic retainers are also well-established treatment devices. While appliances like braces or aligners cause teeth to move into better positions, retainers are designed to keep teeth from moving—helping them to stay in those positions. After active orthodontic treatment, a period of retention is needed to allow the bite to stabilize. Otherwise, the teeth can drift right back to their old locations, undoing the time and effort of orthodontic treatment.
So Robbie has the right idea there too. However, for those who don’t relish the idea of wearing a plastic appliance, it’s often possible to bond a wire retainer to the back surfaces of the teeth, where it’s invisible. No matter which kind you choose, wearing a retainer can help keep your smile looking great for many years to come.

While many people still consider dental implants the "new kids on the block" in dental restoration, they're now in their fourth decade of use. And since their inception implant technology has continued to improve and revolutionize how we replace missing teeth.
Implants are a different "species" compared to other restoration methods. To be precise, an implant is a tooth root replacement—usually a titanium metal post imbedded directly into the jaw bone. Titanium is not only a biocompatible metal, but bone cells naturally grow on its surface to create a strong and durable hold. It's this secure hold that's most responsible for implants' high long-term success rate.
But we should also credit some of this success to the steady stream of advances over the years in implant construction and supporting technologies. For one thing, we're now more accurate and precise with implant placement thanks to advances in computer tomography (CT) and cone beam CT (CBCT) scanning.
These digital processes merge a series of images taken by a special camera to form a three-dimensional model of the jaw. We can manipulate this model on a computer monitor to view it from different vantage points. It can help us locate and avoid anatomical structures like nerves and sinuses when determining where to place a future implant. CT and CBCT are especially useful when there's a concern about adequate available bone, a necessity for stable implants.
Technology has also improved how we create surgical guides, often used during implant surgery to obtain the most accurate results. Surgical guides are custom-made devices that fit over the teeth with the drilling locations for the implants marked on them. Recent advances in 3-D printing have made these guides even more accurate so that they fit more securely in the mouth. This greater stability increases their accuracy during the drilling sequence during surgery.
These and other advances are helping ensure every implant is a success story. The end result is both a functional restoration and a beautiful smile.

During your lifetime you’ll eat thousands of meals — and generate a lot of force from chewing over the years. But thanks to a support system of gum tissues and bone, your teeth can normally handle it.
What your teeth can’t handle, though, are higher than normal chewing forces on a continual basis. This can happen if you grind your teeth, which can produce 20-30 times the normal force. The habit often arises in adults because of high stress and often occurs during sleep.
These abnormal forces can stretch the periodontal ligaments that hold teeth in place, cause the teeth to become loose and at increased risk for loss. The best treatment strategy is to reduce clenching with, for example, muscle relaxants or anti-inflammatory drugs or lower the effects with a mouth guard that won’t allow the teeth to make solid contact during clenching.
Your teeth can also become loose even with normal chewing forces if you have advanced periodontal (gum) disease. Gum disease arises from dental plaque, a thin film of bacteria and food particles left on teeth due to poor oral hygiene. As it builds up, it causes inflammation of the gum tissues resulting in bone loss and causing the gums to detach from the teeth, increasing pocket depth.
Our first step in this case is to treat the gum disease by removing plaque and calculus (tartar) from all tooth and gum surfaces. This includes infected areas below the gum line and around the roots, a circumstance that could require surgical access.
As treatment progresses in either of these scenarios the gum tissues heal and often regain their attachment to the teeth. But that can take time, so we may need to stabilize any loose teeth in the short term. The most common way is to splint them to other secure teeth. This is done by using a clear acrylic bonding material to join the loose teeth together with a strip of metal or other rigid material (like joining pickets in a fence).
When symptoms arise, quick action is the key to preventing lost teeth. If you notice swollen, painful or bleeding gums or especially loose teeth, don’t delay — contact us so we can begin treatment as soon as possible.

For most of us, brushing and flossing is a routine part of daily life. But has it become such a routine that you may not be getting the most out of your daily regimen?
First, let's be clear about what you're trying to accomplish with these two important hygiene tasks, which is to remove as much accumulated dental plaque as possible. This thin film of bacteria and food particles is the primary cause for both tooth decay and periodontal (gum) disease.
So how can you tell if you're effectively cleaning dental plaque from your teeth? Here are 4 ways to check your brushing and flossing skills.
The tongue test. Move your tongue across the surface of your teeth, especially at the gum line, immediately after brushing and flossing. "Plaque-free" teeth will feel smooth and slick. If you feel any grittiness, though, you may be missing some plaque.
Floss check. For a similar effect after your daily hygiene take a fresh piece of floss and run it up and down your teeth. If the teeth are clean and you are using un-waxed floss, the floss should "squeak" as you move it up and down.
Disclosing agents. You can also occasionally use a plaque disclosing agent. This product contains a solution you apply to your teeth after brushing and flossing that will dye any leftover plaque a specific color. Disclosing agents are handy for uncovering specific areas that require more of your future hygiene attention. And don't worry—the dye is temporary and will fade quickly.
Dental visits. For the ultimate test, visit your dentist at least twice a year. Not only can dental cleanings remove hard to reach plaque and calculus (hardened tartar), but your dentist or hygienist can evaluate how well you've been doing. Consider it your "final exam" for oral hygiene!
Be sure to also ask your dental provider for tips and training in better brushing and flossing. Becoming more effective at these critical tasks helps ensure you're keeping your teeth and gums free of disease.
