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.
