Digital computer technology has made a big impact on cosmetic dentistry. We can now simulate on a monitor display of your face how your new smile will appear after dental work, thanks to a graphics program specifically designed for cosmetic dentistry.
While that's an amazing development, we can also take it a step further by creating the look of a new smile on your actual teeth during an office visit. We call it a “trial smile.”
To create a trial smile, we begin with composite resin, a tooth-colored bonding material, and fashion it into temporary veneers or crowns that we then temporarily place over your teeth. This gives us the chance to see what your new smile will look like in all three spatial dimensions (rather than the two-dimensional view on a computer monitor) and while your face is in motion as you talk and smile. This can give us a great deal more detail to help better evaluate your proposed look.
A trial smile also helps us in planning your new look. Like you, we want the best result possible: a trial smile allows us to see how your jaw movement interacts with your updated look and if everything works together as it should. It will also give us a better idea how much tooth structure we'll need to remove to accommodate your permanent veneers or crowns — the less, of course, the better.
Although you won't be able to take your trial smile with you when you leave, we can take a photograph you can review later, as well as show friends and family for their opinion. Trial smiles do add some cost to treatment, but the proportion of expense to the benefit of actually viewing your smile in this fashion is well worth it. It's one more way we can ensure your final new smile meets your expectations.

Wearing braces isn't just for teenagers — straightening teeth can be just as viable a need when you're an adult. For example, it may be necessary to first move teeth away from an empty tooth socket before you obtain a dental implant or other restoration.
But braces could have complications, especially if you have periodontal (gum) disease. These infections caused by plaque, a thin film of bacteria and food particles, inflame and weaken gum tissues and erode supporting bone. It can be treated and brought under control — but keeping it under control requires daily brushing and flossing, along with frequent office cleanings and checkups.
Braces can make this more difficult: it's harder to brush and floss effectively through the hardware of brackets and wires, which can give plaque a chance to build up. Patients susceptible to gum disease are more likely to have re-infections while wearing braces. The hardware can also cause enamel to come in prolonged contact with acid, which can dissolve its mineral content and open the door to tooth decay.
Clear aligners are an alternative to braces that can accomplish tooth movement while minimizing infection flare-ups for people with gum disease. Aligners are a series of customized clear plastic trays worn over the teeth, with each succeeding tray incrementally moving the teeth further than the preceding one. After wearing one tray for a specified time period, you then switch to the next tray. The teeth gradually move to the desired new position over the course of the aligner series.
This option is especially advantageous for gum disease patients because the trays can be removed temporarily for brushing and flossing. There are also other benefits: we can hide a missing tooth space with a temporary false tooth attached to the aligner; and, they're nearly invisible so it won't be obvious to others you're undergoing orthodontic treatment.
Not all orthodontic situations benefit from this alternative, while some cases may call for a combination approach between aligners and braces. But in the right setting, clear aligners are a good choice for not only obtaining better teeth position, but also helping you avoid a new encounter with dental disease.
In the last half century, fluoride has become an effective weapon against tooth decay. The naturally occurring mineral helps strengthen enamel, the teeth's hard, protective cover.
Although it's safe for consumption overall, too much during early tooth development can lead to fluorosis, a brownish, mottled staining in enamel. To avoid it, a child's daily consumption of fluoride should optimally be kept at around 0.05-0.07 milligrams per kilogram of body weight, or an amount equal to one-tenth of a grain of salt per two pounds of weight.
The two main therapeutic fluoride sources have limits to help maintain this balance: utilities that fluoridate drinking water are required to add no more than 4 parts fluoride per million (ppm) of water; toothpaste manufacturers likewise only add a small amount of fluoride compared to clinical gels and pastes dentists apply to teeth for added decay protection.
But drinking water and toothpaste aren't the only sources of fluoride your child may encounter. Even if you have a non-fluoridated water supply, you should still keep a close watch on the following items that could contain fluoride, and discuss with us if you should take any action in regard to them.
Infant formula. The powdered form especially if mixed with fluoridated water can result in fluoride concentrations 100 to 200 times higher than breast or cow's milk. If there's a concern, use fluoride-free distilled or bottled spring water to mix formula.
Beverages. Many manufacturers use fluoridated water preparing a number of packaged beverages including sodas (two-thirds of those manufactured exceed .6 ppm), soft drinks and reconstituted fruit juices. You may need to limit your family's consumption of these kinds of beverages.
Certain foods. Processed foods like cereals, soups or containing fish or mechanically separated chicken can have high fluoride concentrations, especially if fluoridated water was used in their processing. When combined with other fluoride sources, their consumption could put children at higher risk for fluorosis.
Toothpaste. Although mentioned previously as a moderate fluoride source, you should still pay attention to how much your child uses. It doesn't take much: in fact, a full brush of toothpaste is too much, even for an adult. For an infant, you only need a smear on the end of the brush; as they grow older you can increase it but to no more than a pea-sized amount.

If you've noticed one of your teeth feeling loose, you're right to believe it's not a good thing. Loose permanent teeth are a sign of an underlying problem.
Periodontal (gum) disease is usually the culprit. Caused by bacterial plaque, a thin film of food particles, gum disease causes the tissues that support teeth to weaken and detach. While a tooth can become loose from too much biting force (primary occlusal trauma), it's more likely bone loss from gum disease has caused so much damage that even the forces from normal biting can trigger looseness.
A loose tooth must be treated or you may lose it altogether. If it's from gum disease, your treatment will have two phases.
In the first phase we need to stop the gum infection by removing plaque and calculus (hardened plaque deposits). Hand instruments known as scalers or ultrasonic equipment are usually sufficient for removing plaque and calculus around or just below the gum line. If the plaque extends deeper near or around the roots, we may need to consider surgical techniques to access these deeper deposits.
Once the infection is under control and the tissues have healed, we can then undertake the second phase: reducing biting forces by breaking clenching and grinding habits, doing a bite adjustment for advanced problems and securing loose teeth with splinting.
Although there are different types of splinting — both temporary and permanent — they all link loose teeth to adjacent secure teeth much like pickets in a fence. One way is to bond dental material to the outer enamel of all the teeth involved; a more permanent technique is to cut a small channel extending across all the teeth and bond a rigid metal splint within it.
To reduce biting forces on loose teeth, we might recommend wearing a bite guard to keep the teeth from generating excessive biting forces with each other. We may also recommend orthodontics to create a better bite or reshape the teeth's biting surfaces by grinding away small selected portions of tooth material so they generate less force.
Using the right combination of methods we can repair loose teeth and make them more secure. But time is of the essence: the sooner we begin treatment for a loose tooth, the better the outcome.
