The mouth isn’t an island unto itself — problems there may be indicative of deeper physical or emotional issues. Â The condition of a family member’s teeth and gums, for example, could be signs of bulimia, an eating disorder.
Characterized by food binging and purging through self-induced vomiting, bulimia can also have a severe effect on the teeth. Regular inducement of vomiting introduces stomach acid into the mouth that can attack and soften the mineral content of tooth enamel. As a result, 90% of bulimics develop enamel erosion.
The erosion pattern often differs from that produced by other high acid causes like the over-consumption of sodas. Because the tongue instinctively covers the back of the bottom teeth during vomiting, they’re often shielded from much of the acid wash. Bulimics are much more apt to exhibit heavier erosion on the upper front teeth, particularly on the tongue side and biting edges.
Bulimia and similar disorders produce other signs as well, like soft tissue ulceration or swollen salivary glands that exhibit puffiness of the face. The roof of the mouth, throat and back of the tongue may appear roughened from the use of fingers or objects to induce gagging.
Unlike sufferers of anorexia nervosa who tend to be negligent about their hygiene (which itself increases their risk of dental disease), bulimics have a heightened sensitivity to their appearance. This concern may prompt them to aggressively brush right after purging, which can cause more of the softened enamel to be removed.
Treating the dental consequences of bulimia requires a two-pronged approach. In the short term, we want to lessen the impact of stomach acid by discouraging the person from brushing immediately after purging — better to rinse with water and a little baking soda to buffer the acid and wait about an hour before brushing. We may also suggest a sodium fluoride mouth rinse to help strengthen and re-mineralize the enamel.
In the long-term, though, the disorder itself must be addressed through professional help. One good source is the National Eating Disorders website (nationaleatingdisorders.org). Besides information, the association also provides a toll-free helpline for referrals to professionals.
As with any eating disorder, bulimia can be trying for patients and their families. Addressing the issue gently but forthrightly will begin their journey toward the renewal of health, including their teeth and gums.

What do young saber tooth tigers, which have been extinct about 10,000 years, have in common with human kids today? At first glance, not a lot. Smilodon fatalis, the big cat of North America, reached adulthood at around age three and weighed up to 600 pounds. But these ice-age mammals are probably best known for their dagger-like canine teeth, which (as shown by many well-preserved skeletons) grew up to 7 inches long. And that’s where the comparison between kids and kitties gets interesting.
The toothy felines had primary (baby) teeth and adult teeth, which developed in a similar way to human dentition. The primary teeth came in first, persisted during the young cat’s development, and shared space in the mouth as the adult teeth were erupting (growing in) — with one big difference. According to a recent study reported in the academic journal PLOS ONE, those colossal canines grew at an astonishing rate: up to 6 millimeters per month! By comparison, human primary teeth emerge from the gums at around 0.7mm per month, while permanent teeth may grow up to 2mm per month.
It’s understandable why those tiger teeth developed so rapidly: Life in the Ice Age was hard, and predators needed every advantage just to stay alive. But while human baby teeth take longer to develop (and to go away), they, too, are vitally important.Â For one thing, the primary teeth let kids bite, chew, speak (and smile) properly, until they are replaced by adult teeth — a process that isn’t usually finished until a child reaches the age of 12-13. So those “baby” teeth allow kids to have good nutrition — and positive social interactions — for a significant part of childhood!
There’s another important thing primary teeth do before they’re gone: They help ensure that the succeeding teeth come in properly, by holding a space in the jaw that will later be filled by a permanent tooth. If baby teeth are lost prematurely, those spaces can close up, resulting in permanent teeth that emerge too close together, or in the wrong places. This condition, called malocclusion (bad bite), can usually be corrected by orthodontics. But it’s better to avoid the inconvenience (and cost) of braces, if possible.
That’s why it’s so important to take care of your child’s baby teeth. Even though they won’t be around forever, they have a vital role to play right now. So be sure proper attention is paid to your child’s oral hygiene: That means avoiding sugar, and remembering to brush and floss every day. And be sure to come in regularly for routine exams, cleanings, and needed care. It’s the best way to keep those little teeth from “going extinct” too soon!

Restoring a smile with implants involves more than the surgical procedure itself. We must also take into consideration the quality of the bone they’re placed into and the gums that will surround them — the “canvas” that showcases your new beautiful smile.
Bone — not only at the missing tooth site but supporting neighboring teeth as well — is the foundation for a successful implant. Without an adequate amount of bone, we can’t place an implant to achieve a final life-like appearance. Inadequate bone can be a problem if the tooth has been missing for awhile — without the stimulation of biting forces from the tooth, the bone can shrink gradually over time. Periodontal (gum) disease and other dental conditions can also cause bone loss.
The health of your gums — as well as the tissue type you’ve inherited from your parents, thin or thick — can also determine how natural the implant crown looks as it emerges from them. If they’ve receded due to gum disease they may not regenerate sufficiently, making your teeth longer-looking or leaving the triangular bit of gum tissue between the teeth, the papillae, noticeably missing. If you’ve inherited thin tissue gums, you’re also more susceptible to gum recession and there’s less margin for error during implant surgery.
There are some things we can do to minimize these problems. Tooth removal to make room for the new implant needs to be done carefully with as little tissue trauma as possible; it’s also helpful to place grafting material in the empty socket immediately after extraction, especially if there’s going to be a time gap before implant placement. If bone loss has already occurred, we can also use similar grafting techniques to rebuild the bone.
Likewise we need to take special care during implant surgery when dealing with thin or diseased gums. With the latter, it’s usually necessary to bring the gum disease under control and allow the gums to heal first. In extreme cases, cosmetic gum surgery may also help restore lost tissues and create a more natural look between the gums and the implant crown.
Creating a natural appearance with implants is a blend of technical skill and artistic insight. Keeping the balance between all these factors will produce a smile you’ll be proud to show.

As a member of the best-selling pop group Spice Girls, Mel C (AKA Sporty Spice) enjoyed her share of musical superstardom. At the band’s peak in the Nineties, the young singer’s signature look featured baggy sweatpants, an assortment of tattoos, a nose stud and a gold-capped incisor, front and center in her mouth. Today, Melanie Chisholm is still singing — but now she’s a mom, an amateur triathlete… and that gold tooth is just a memory. Not only that, her smile looks more evenly spaced and whiter than it did when she was referred to as the “tomboy” of the group.
What happened? In our view, it all boils down to changing tastes — plus a little bit of help from dental professionals. As the “wannabe” singer proves, there’s no single standard when it comes to making your teeth look their best. Your own look is unique to you — and your smile can reflect that individuality.
For example, crowns (caps) are substantial coverings that may be placed on teeth when they are being restored. They are available in three types: gold, all-porcelain, or porcelain-fused-to-metal. The latter two are tooth-colored, while the gold is — well, shiny like gold bling. Which one is right for you? In many cases, it’s your choice.
Likewise, dental veneers — wafer-thin shells that can correct cosmetic issues by covering the surface of your teeth — can be made in a variety of shades. Their hues may range from natural ivory to Hollywood white, and everything in between. What’s the best color for you? Only you can say.
Some people opt for a “smile makeover” that uses small irregularities in the spacing and color of teeth to create a more “natural” look. Other folks want a perfectly even, brilliant white smile that dazzles the eye. Still others are looking to match or restore the smile they once had — perhaps even re-creating a signature gap between the teeth. As long as there are no other dental issues involved, the choice is yours.
So if you’re unhappy with your smile — or if you feel it doesn’t reflect the person you “wannabe” — why not talk to us about a smile makeover? Just call our office to schedule a consultation. You can learn more about this topic in the Dear Doctor magazine articles “Beautiful Smiles by Design” and “The Impact of a Smile Makeover.”
It’s true — thumb sucking beyond age 4 can cause bite problems for permanent teeth. But prolonged thumb sucking is just one of a number of possible contributing factors for a bad bite (malocclusion). A dentist must identify all the factors involved when a bad bite is present — their involvement is essential for a successful treatment outcome.
A fairly benign habit for infants and toddlers, thumb sucking is related to an “infantile swallowing pattern” young children use by thrusting their tongues forward between the upper and lower teeth when they swallow. Around age 4, though, they usually transition to an adult swallowing pattern in which the tongue rests on the roof of the mouth just behind the front teeth. Thumb sucking stops for most children around the same time.
Thumb sucking beyond this age, though, can put increased pressure on incoming permanent teeth pushing them forward. This could lead to an “open bite” in which the upper and lower teeth don’t meet when the jaws are closed. The tongue may also continue to thrust forward when swallowing to seal the resulting gap, which further reinforces the open bite.
Before treating the bite with braces, we must first address the thumb sucking and improper tongue placement when swallowing — if either isn’t corrected the teeth could gradually revert to their previous positions after the braces come off. Besides behavioral incentives, we can also employ a thin metal appliance called a “tongue crib” placed behind the upper and lower incisors. A tongue crib discourages thumb sucking and makes it more difficult for the tongue to rest within the open bite gap when swallowing, which helps retrain it to a more normal position.
An open bite can also occur if the jaws develop with too much vertical growth. Like thumb sucking and improper tongue placement, abnormal jaw growth could ultimately cause orthodontic treatment to fail. In this case, though, surgery may be necessary to correct the jaw structure.
With all these possible variables, our first step needs to be a thorough orthodontic exam that identifies all the cause factors for your child’s specific malocclusion. Knowing if and how thumb sucking may have contributed to the poor bite will help us design a treatment strategy that’s successful.
