Teeth are composed of layers of different types of tissue. The main inner layers — the pulp and dentin — help the teeth respond and adapt to external forces. But they’re vulnerable to decay and quite sensitive to environmental extremes. They are protected from all these by a coating of enamel, made of the hardest material found in the human body.
But while enamel is strong, it’s not invincible — it can soften and dissolve (de-mineralize) if the mouth environment becomes too acidic. While de-mineralization occurs normally whenever the mouth becomes too acidic after eating or drinking, saliva helps neutralize the acid (buffering); in fact, saliva can restore to the enamel some of the calcium and other minerals it has lost (a process called re-mineralization).
If the acidic level remains too high for too long it can overwhelm saliva’s buffering ability and cause permanent mineral loss to the enamel. This erosion leaves teeth more susceptible to decay and disease and could lead to tooth loss. With this in mind, here’s some ways you can help preserve your enamel:
- Wait about thirty to sixty minutes after eating or drinking to brush your teeth. Counterintuitive as this may sound, it takes about thirty minutes for saliva to restore a normal pH level and re-mineralize the enamel. If you brush within this window of time, you could brush away some of the softened minerals from the enamel.
- Only brush twice a day. Over-brushing causes undue enamel wear, as well as contributing to receding gums.
- Take advantage of less acidic or mineral-rich beverages. Drink milk or water most of the time, rather than juices, sodas or sports drinks. The calcium in milk or as an additive to acidic beverages aids in buffering and re-mineralization.
- Use a straw for acidic beverages. With a straw your teeth avoid direct contact with most of the beverage’s acid, a key factor in de-mineralization.
- Avoid eating just before bed. Saliva flow decreases significantly when we sleep. If you eat right before bed, there may be less saliva available for buffering and re-mineralization.
Following these tips, along with effective oral hygiene, will go a long way in protecting your teeth’s enamel coating — and preserving your teeth in the long run.

Before she began hosting the long-running TV competition Top Chef, Padma Lakshmi was a well-known model and successful cookbook author. (Appropriately, she is said to have been “discovered” by a modeling agent while sitting in a café in Madrid.) Yet the Indian-born beauty's striking look — at once exotic and familiar — doesn't come from any cookie-cutter mold.
So when Lakshmi had cosmetic work done on her teeth, early in her career, her dentist didn't use a cookie-cutter approach either: Instead, her smile was carefully designed, using small amounts of bonding material to brighten her teeth and to bring their shape and spacing into harmony with her facial features.
Dentistry by Design
What exactly is smile design — and what could it do for you? Essentially, it's the process of evaluating your smile in concert with the appearance of your entire face, and visualizing the changes — some dramatic and some subtle — that will make it really shine. Some aspects we consider include the face's shape, the proportion or “balance” of facial features, the complexion, eye and lip color and form, and the overall dimensions of the smile.
Based on dental aesthetics and clinical experience, we will probably have a number of suggestions to make on how you can improve your smile. Your input will also be very important; while some individuals prefer perfectly even teeth and a sparkling “Hollywood white” smile, others are looking for a result that's more in keeping with a “natural” look: slight irregularities in tooth shape, spacing, and even color.
There's no right or wrong answer here: Having a “perfect” smile means what's perfect for you, so it's very important for dentists and patients to communicate openly during the smile design process. But sometimes, words alone just aren't enough to convey the subtle dimensions of beauty.
The Trial Smile
Fortunately, it's now possible to preview your “perfect” smile using a number of different techniques. Advances in computer imaging make this the first step in previewing your new smile — you can see the changes before a single tooth is touched! Still, many people find that having a more concrete picture is helpful. The next step is to make a 3-D mock-up the proposed dental work on an actual model of your mouth. That way, you can see a physical representation of the final results — and even turn it around and hold it in your hands.
There's still one more way to really experience the difference cosmetic treatments can make without committing to a permanent change: the provisional restoration. Here, tooth-colored bonding material and other techniques are used to actually create the new smile — temporarily. This gives you time to “live with it,” and see if the proposed changes work for you. If everything goes well with the provisional work, the permanent restoration is guaranteed to please.
So if you want holiday treats, get out the cookie cutter — but if you're looking for a smile that's uniquely yours, and one that enhances your own individual appearance… call our office and ask about a smile design consultation.
