What makes a beautiful smile? The teeth, of course: bright, evenly shaped and precisely aligned with each other. But your teeth can be as perfect as can be and your smile will still appear unattractive.
The reason? Your gums show more than they should when you smile.
What's considered a gummy smile is largely a matter of perception that can vary from person to person. As a rule of thumb, though, we consider a smile “gummy” if four millimeters (mm) or more of the gums show.
Fortunately, we can minimize the gums' prominence and make your smile more attractive. But what methods we use will depend on why your gums stand out. And it's not always because of the gums themselves.
It could be your teeth didn't erupt normally during dental development. Mature crown (the visible part of the tooth) length is normally about 10 mm with a width about 75-85% of that. But an abnormal eruption could result in teeth that appear too short, which can make the gums stand out more. We can correct this with a surgical procedure called crown lengthening in which we remove excess gum tissue and, if necessary, reshape the underlying bone to expose more of the tooth crown.
Another potential cause is how far your upper lip rises when you smile. Normally the lip rises only enough to reveal about 4 mm of teeth. In some cases, though, it may rise too high and show more of the gums. We can modify lip movement in a number of ways, including Botox injections to temporarily paralyze the lip. A more permanent solution is a lip stabilization procedure. It sounds bad, but it's a fairly simple procedure to surgically reposition the muscle attachments to restrict movement.
Your gummy smile may also result from an upper jaw too long for your facial structure. We can correct this with orthognathic (“ortho” – straighten, “gnathos” – jaw) surgery. During the procedure the surgeon permanently positions the jaw further up in the skull; this will reduce the amount of teeth and gums displayed when you smile.
Discovering the true cause of your gummy smile will determine how we treat it. After a complete oral examination, we can then discuss your options to transform your smile into a more attractive one.

After your son or daughter's dental exam, you expect to hear about cavities, poor bites or other dental problems. But your dentist might suggest a different kind of problem you didn't expect—an eating disorder.
It's not a fluke occurrence—a dental exam is a common way bulimia nervosa or anorexia nervosa come to light. That's because the teeth are often damaged by the behaviors of a patient with an eating disorder.
Most of this damage occurs because of purging, the practice of induced vomiting after eating. During vomiting stomach acid can enter the mouth and "wash" against the back of the teeth. After repeated episodes, the acid dissolves the mineral content of tooth enamel and causes it to erode. There's also a tell-tale pattern with eating disorders: because the tongue partially shields the back of the lower teeth while purging, the lower teeth may show less enamel erosion than the upper.
Hygiene practices, both negligent and too aggressive, can accelerate erosion. Anorexics often neglect basic grooming and hygiene like brushing and flossing, which increases the likelihood of dental disease. Bulimia patients, on the other hand, can be fastidious about their hygiene. They're more likely to brush immediately after purging, which can cause tiny bits of the enamel immediately softened by the acid wash to slough off.
In dealing with a family member's eating disorder, you should consider both a short and long-term approach to protect their dental health. In the sort-term the goal is to treat the current damage and minimize the extent of any future harm. In that regard, encourage them to rinse with water (mixed optionally with baking soda to help neutralize acid) after purging, and wait an hour before brushing. This will give saliva in the mouth a chance to fully neutralize any remaining acid. Your dentist may also recommend a sodium fluoride mouth rinse to help strengthen their tooth enamel.
For the long-term, your goal should be to help your loved one overcome this potentially life-threatening condition through counseling and therapy.

Taking steps to treat an eating disorder could save not only your loved one's dental health, but also their life.

It's no secret that many of Hollywood's brightest stars didn't start out with perfectly aligned, pearly-white teeth. And these days, plenty of celebs are willing to share their stories, showing how dentists help those megawatt smiles shine. In a recent interview with W magazine, Emma Stone, the stunning 28-year-old star of critically-acclaimed films like La La Land and Birdman, explained how orthodontic appliances helped her overcome problems caused by a harmful habit: persistent thumb sucking in childhood.
“I sucked my thumb until I was 11 years old,” she admitted, mischievously adding “It's still so soothing to do it.” Although it may have been comforting, the habit spelled trouble for her bite. “The roof of my mouth is so high-pitched that I had this huge overbite,” she said. “I got this gate when I was in second grade… I had braces, and then they put a gate.”
While her technical terminology isn't quite accurate, Stone is referring to a type of appliance worn in the mouth which dentists call a “tongue crib” or “thumb/finger appliance.” The purpose of these devices is to stop children from engaging in “parafunctional habits” — that is, behaviors like thumb sucking or tongue thrusting, which are unrelated to the normal function of the mouth and can cause serious bite problems. (Other parafunctional habits include nail biting, pencil chewing and teeth grinding.)
When kids develop the habit of regularly pushing the tongue against the front teeth (tongue thrusting) or sucking on an object placed inside the mouth (thumb sucking), the behavior can cause the front teeth to be pushed out of alignment. When the top teeth move forward, the condition is commonly referred to as an overbite. In some cases a more serious situation called an “open bite” may develop, which can be difficult to correct. Here, the top and bottom front teeth do not meet or overlap when the mouth is closed; instead, a vertical gap is left in between.
Orthodontic appliances are often recommended to stop harmful oral habits from causing further misalignment. Most appliances are designed with a block (or gate) that prevents the tongue or finger from pushing on the teeth; this is what the actress mentioned. Normally, when the appliance is worn for a period of months it can be expected to modify the child's behavior. Once the habit has been broken, other appliances like traditional braces or clear aligners can be used to bring the teeth into better alignment.
But in Stone's case, things didn't go so smoothly. “I'd take the gate down and suck my thumb underneath the mouth appliance,” she admitted, “because I was totally ignoring the rule to not suck your thumb while you're trying to straighten out your teeth.” That rule-breaking ended up costing the aspiring star lots of time: she spent a total of 7 years wearing braces.
Fortunately, things worked out for the best for Emma Stone: She now has a brilliant smile and a stellar career — plus a shiny new Golden Globe award!

The chances of contracting an infectious disease from a dental visit are extremely low, thanks to the stringent safety standards practiced by over 170,000 dental care providers across the U.S. Without these standards, you and your family would be at risk for diseases like hepatitis from even a routine office visit.
The main prevention focus centers on blood-borne diseases in which blood from an infected person is introduced into the body of another through a cut, incision or injection site. While HIV/AIDS (autoimmune deficiency syndrome) is perhaps the most well known of blood-borne diseases, a more common and thus a more threatening disease is hepatitis. Caused by a pair of viruses known as HBV and HCV, hepatitis damages the liver, which disrupts normal bodily function and can even cause death.
The spread of hepatitis and similar diseases is a major concern for blood transfusion and surgical centers that commonly use invasive procedures and intravenous (IV) equipment. It’s also a concern in dental offices where even a hygienic cleaning may result in some bleeding. To reduce the risk of disease, the dental profession has several layers of both mandatory and recommended standards for protection against viral or microbial transmission.
The Center for Disease Control, for example, publishes and regularly updates recommended procedures for equipment sterilization and disinfection. State level dental licensing boards also mandate safety procedures and require continuing education for infection control as a requirement for re-licensing, as often as two years. Professional organizations such as the American Dental Association (ADA) also encourage safety protocols among its members.
The vast majority of dentists place infection control among their highest priorities. These care providers institute and practice daily protocols and procedures for hand washing, use of masks, gloves and other biohazard protection, and disinfection. Through effective infection control you and your family can receive the dental care you need without endangering your general health.

In the battle against tooth decay, fluoride is an important weapon. Since the discovery of its dental health benefits a century ago, fluoride has been credited with saving countless teeth.
But over its history in dental care, this natural-occurring chemical has also had its share of controversy with concerns raised from time to time on potential health dangers. These run the gamut from “conspiracy theory” speculations to credible research like a 2006 National Research Council study that suggested a possible increased risk of bone fracture or cancer from over-consumption of fluoride.
Even so, there is actually little evidence or even record of incidence for such dire consequences. The only definitive health effect from fluoride found after decades of copious research is a condition called fluorosis, a permanent staining effect on the teeth. Fluorosis poses a cosmetic problem but does not harm the health of the teeth.
Moderation in fluoride use seems to be the key to gaining its health benefits while avoiding fluorosis. One influential fluoride researcher, Dr. Steven Levy, estimates 0.05-0.07 milligrams of fluoride per one kilogram of body weight (about a tenth the weight of a grain of salt for every two pounds) is sufficient to gain the optimum dental benefit from fluoride.
The real question then is whether your family’s current consumption of fluoride is within this range. That will depend on a number of factors, including whether your local water utility adds fluoride to your drinking water supply and how much. You may also be ingesting fluoride through processed foods, juices and even some bottled waters. And you can encounter fluoride in dental care including toothpastes and clinical treatments.
One way to moderate your family’s fluoride intake is to be sure all your family members are using the correct amount of fluoride toothpaste for their age while brushing. Infants need only a slight smear on the end of the brush, while older children can brush adequately with just a pea-sized amount. For other tips and advice, talk to your dentist about your family’s fluoride intake and how you might adjust it.
Even with the possibility of fluorosis, fluoride still provides an incredible benefit in preventing tooth decay. By understanding fluoride and keeping your intake within normal ranges you can maximize its benefit for healthier teeth and minimize the fluorosis risk.
