Roughly 75% of American adults are missing at least one tooth, mostly from disease, trauma or extraction for other dental reasons. A few missing teeth, though, never erupted in the first place.
It’s a rare occurrence, but sometimes people are born without certain teeth, usually back molars or premolars that may not be as visible. Occasionally, though, it’s the more visible upper lateral incisors positioned on either side of the central incisors (the two front teeth on either side of the midline of the face).
Missing incisors can lead to poor bites and create difficulties for speech development and nutrition. But these highly visible (or in this case, “invisible”) teeth can also detract from an otherwise attractive smile.
There are ways, however to correct a smile with missing lateral incisors. Here are 3 of those ways.
Canine substitution. We can fill the vacancy created by the missing incisors by orthodontically moving the canines (the “eyeteeth,” normally next to them) into the space. Braces can close the gap in a conservative way, while possibly correcting any existing bite problems. Because canines are larger than incisors, its often necessary to re-contour them and restore them with a crown, veneer or bonding material to look more natural.
Fixed bridge. A second way to fill the space is with a dental bridge. A bridge consists of a series of crowns fused together in a row. The middle crowns replace the missing teeth; the end crowns cap the natural teeth on either end of the gap, which establishes support for the bridge. Another variation is a cantilever bridge in which only one natural tooth is capped for support. With either type, though, the capped teeth will be permanently reduced in size to accommodate the crowns.
Dental implants. This popular restoration is also a favorite for correcting missing incisors. Implants provide a life-like and durable replacement for missing teeth, while not requiring any alterations to existing teeth as with a bridge. But they are more expensive than the other options, and they require adequate space between the adjacent teeth for insertion, as well as healthy bone for proper placement and anchorage. This is also an option that must wait until the jaw has fully matured in early adulthood.

Generations have depended on dentures to effectively and affordably replace lost teeth. But they do have a major weakness: They contribute to jawbone loss that creates not only mouth and facial problems, but can also ruin a denture’s fit.
Bone loss is a normal consequence of losing teeth. The biting forces normally generated when we chew stimulate new bone to replace older bone. When a tooth is missing, however, so is that chewing stimulation. This can slow bone replacement growth and gradually decrease the density and volume of affected bone.
While dentures can restore dental appearance and function, they can’t restore this growth stimulation. What’s worse, the pressure of the dentures against the gum-covered jaw ridge they rest upon may irritate the underlying bone and accelerate loss.
But there is a solution to the problem of denture-related bone loss: an implant-supported denture. Rather than obtaining its major support from the gum ridges, this new type of denture is secured by strategically-placed implants that connect with it.
Besides the enhanced support they can provide to a denture restoration, implants can also deter bone loss. This is because of the special affinity bone cells have with an implant’s imbedded titanium post. The gradual growth of bone on and around the implant surface not only boosts the implant’s strength and durability, it can also improve bone health.
There are two types of implant-supported dentures. One is a removable appliance that connects with implants installed in the jaw (three or more for the upper jaw or as few as two in the lower). It may also be possible to retrofit existing dentures to connect with implants.
The other type is a fixed appliance a dentist permanently installs by screwing it into anywhere from four and six implants. The fixed implant-supported denture is closer to the feel of real teeth (you’ll brush and floss normally), but it’s usually more costly than the removable implant-supported denture.
While more expensive than traditional ones, implant-supported dentures still cost less than other restorations like individual implant tooth replacements. They may also help deter bone loss, which may lead to a longer lasting fit with the dentures. Visit your dentist for an evaluation of your dental condition to see if you’re a good candidate for this advanced form of dental restoration.

How many actresses have portrayed a neuroscientist on a wildly successful TV comedy while actually holding an advanced degree in neuroscience? As far as we know, exactly one: Mayim Bialik, who plays the lovably geeky Amy Farrah Fowler on CBS' The Big Bang Theory… and earned her PhD from UCLA.
Acknowledging her nerdy side, Bialik recently told Dear Doctor magazine, “I'm different, and I can't not be different.” Yet when it comes to her family's oral health, she wants the same things we all want: good checkups and great-looking smiles. “We're big on teeth and oral care,” she said. “Flossing is really a pleasure in our house.”
How does she get her two young sons to do it?
Bialik uses convenient pre-loaded floss holders that come complete with floss and a handle. “I just keep them in a little glass right next to the toothbrushes so they're open, no one has to reach, they're just right there,” she said. “It's really become such a routine, I don't even have to ask them anymore.”
As many parents have discovered, establishing healthy routines is one of the best things you can do to maintain your family's oral health. Here are some other oral hygiene tips you can try at home:
Brush to the music — Plenty of pop songs are about two minutes long… and that's the length of time you should brush your teeth. If brushing in silence gets boring, add a soundtrack. When the music's over — you're done!
Flossing can be fun — If standard dental floss doesn't appeal, there are many different styles of floss holders, from functional ones to cartoon characters… even some with a martial-arts theme! Find the one that your kids like best, and encourage them to use it.
The eyes don't lie — To show your kids how well (or not) they are cleaning their teeth, try using an over-the-counter disclosing solution. This harmless product will temporarily stain any plaque or debris that got left behind after brushing, so they can immediately see where they missed, and how to improve their hygiene technique — which will lead to better health.
Have regular dental exams & cleanings — When kids see you're enthusiastic about going to the dental office, it helps them feel the same way… and afterward, you can point out how great it feels to have a clean, sparkling smile.
If you think “vaping” electronic cigarettes (e-cigarettes for short) is healthier for your teeth and gums than smoking cigarettes, you might be disappointed with the latest research. A number of studies seem to indicate e-cigarettes could be just as damaging to your mouth as traditional cigarettes.
An e-cigarette is a device containing a chamber for liquids and a means to heat the liquid into a vapor. The user then inhales or “vapes” the vapor, which contains nicotine and flavorings. The heat also pressurizes the vapor causing it to expel as an aerosol into the mouth.
Researchers have found the ingredients and aerosol effect could lead to potential health problems. An Ohio State University researcher found that vaping disrupted the normal balance of microorganisms in the mouth known as the oral microbiome. This imbalance could make it easier for disease-causing bacteria to proliferate, particularly those most responsible for periodontal (gum) disease.
Another study coming out of the University of Rochester and Stony Brook University in New York detected cell damage in gum tissue caused by e-cigarette vapor similar to that caused by regular cigarette smoke. Some of this damage seemed to result from the flavoring agents used in the e-cigarette liquid, as well as nicotine.
Another study from Quebec, Canada appears to concur with the New York study. These researchers found the damage caused by e-cigarette vapor might substantially increase the rate of cell death in oral tissues by as much as 50% over a short period of time. This kind of damage can lead to higher risks of dental diseases like gum disease or tooth decay.
While we don’t know the long-term effect of using e-cigarettes on both oral and general health, these studies are alarming: They seem to show vaping may cause some of the same problems as smoking. With the jury still out, the prudent thing to do is limit or avoid vaping altogether to protect your mouth from these unhealthy outcomes.
With summer winding down, parents are turning their attention to their kids' upcoming school year. August is often a busy time for families rushing to buy school supplies and fresh sets of clothes and shoes. Although hectic, these last few weeks before school starts are also ideal for focusing on dental health.
As you prepare for the school year, be sure to include these dental health items on your to-do list.
Make a dental appointment. Start the school year off right with a dental cleaning and checkup. Along with daily hygiene, dental visits are key to disease prevention and optimal oral health. Make those appointments early, though: Most dentists report an upsurge in patient visits this time of year.
And if you haven't already, set up an orthodontic evaluation: Having an orthodontist examine your child around age 6 could uncover an emerging bite problem. Early intervention might prevent the need for more costly future orthodontic treatments.
Plan for healthy school snacking. While kids are home on summer break, it's probably easier to keep an eye on the quality of their snacks. But being away from your watchful gaze at school means your children may encounter snacks that are not quite up to your tooth-healthy standards.
Even though schools adhere to federal nutrition standards for food provided on school property, many dentists don't believe they go far enough. Your kids' classmates can also be a source of unhealthy snack choices, so plan ahead to provide your kids an array of snacks to carry to school that they like and that support healthy teeth and a healthy body.
Get a custom mouthguard for your student athlete. If your child is going to play football, basketball or some other contact sport, make sure they have dental protection. A hard impact to the face can cause significant dental damage that's costly to treat, but a mouthguard worn during play can protect the teeth and gums by cushioning the blow.
You can purchase retail mouthguards at your local sporting goods store. Your best option, though, is a mouthguard custom-made by your dentist based on your child's individual mouth measurements. Although more expensive, custom mouthguards offer superior protection, and they're more comfortable to wear.
When the school bell rings, you want your kids as prepared as possible. Make sure their teeth and gums are ready too. If you would like more information about best practices for your child's dental care, please contact us or schedule an appointment for a consultation.
