If you've thought the ads for a “new tooth in one day” seemed too good to be true, we have…sort of good news. You can get a new “tooth” in one visit, but only if your dental situation allows it.
The restoration in question is a dental implant, a metal post (usually titanium) surgically imbedded into the jawbone. They're especially durable because bone cells naturally grow and adhere to an implant's titanium surface, a process called osseointegration. Over time this process creates a strong bond between implant and bone.
Usually, we allow a few weeks for the implant to fully integrate with the bone before attaching the visible crown. With “tooth in one day,” though, we attach a crown at the same time as we install the implant, albeit a temporary crown. It's more aesthetic than functional, designed to avoid biting forces that could damage the implant while it integrates with the bone. When that process finishes, we'll install a permanent porcelain crown.
The health of your supporting bone and other structures will largely determine whether or not you're a candidate for this “tooth in one day” procedure. Your bone must be sufficiently healthy, as well as the gums surrounding the implant and the tooth's bony socket.
If, on the other hand, you have significant bone loss, gum recession or socket damage, we may first need to deal with these, usually by grafting tissue to the affected areas to stimulate new growth. Your implant, much less a temporary crown, will likely have to wait until the affected tissues have healed.
The bone can also be healthy enough for implant placement, but might still need time to integrate with the implant before attaching any crown. Instead, we would suture the gums over the implant to protect it, then expose and attach a permanent crown to the implant a few weeks later.
Obtaining even a temporary crown the same day as your implant can do wonders for your appearance. A more important goal, though, is a new tooth that you can enjoy for many, many years. To achieve that may mean waiting a little longer for your new beautiful smile.

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.

The U.S. Centers for Disease Control and Prevention calls it “one of the ten most important public health measures of the 20th Century.” A new vaccine? A cure for a major disease? No—the CDC is referring to the addition of fluoride to drinking water to prevent tooth decay.
Fluoride is a chemical compound found in foods, soil and water. Its presence in the latter, in fact, was key to the discovery of its dental benefits in the early 20th Century. A dentist in Colorado Springs, Colorado, whose natural water sources were abundant with fluoride, noticed his patients' teeth had unusual staining but no tooth decay. Curious, he did some detective work and found fluoride in drinking water to be the common denominator.
By mid-century, fluoride was generally recognized as a cavity fighter. But it also had its critics (still lively today) that believed it might also cause serious health problems. Ongoing studies, however, found that fluoride in tiny amounts—as small as a grain of sand in a gallon of water—had an immense effect strengthening enamel with scant risk to health.
The only condition found caused by excess fluoride is a form of tooth staining called fluorosis (like those in Colorado Springs). Fluorosis doesn't harm the teeth and is at worst a cosmetic problem. And it can be avoided by regulating the amount of ingested fluoride to just enough for effectively preventing tooth decay.
As researchers have continued to learn more about fluoride, we've fine-tuned what that amount should be. The U.S. Public Health Service (PHS), which sets standards for fluoride in drinking water, now recommends to utilities that fluoridate water to do so at a ratio of 0.7 mg of fluoride to 1 liter of water. This miniscule amount is even lower than previous recommendations.
The bottom line: Fluoride can have an immense impact on your family's dental health—and it doesn't take much. Excessive amounts, though, can lead to dental staining, so it's prudent to monitor your intake. That means speaking with your dentist about the prevalence of fluoride in your area (including your drinking water) and whether you need to take measures to reduce (or expand) your use of it.
