Humans naturally react with pleasure to a beautiful smile. Starting with our mother's joy at seeing our first smile, we have learned throughout our lives that a smile is an invitation to a positive interaction. But are some smiles more beautiful than others? What is it that makes a smile beautiful?

As with art and music, people's perceptions of beauty differ with their backgrounds and culture. Most people respond well to an appearance of healthy teeth and gums. Some feel that teeth must be very white and bright, while others look for even alignment and proportionally sized teeth. With today's dentistry, all of these factors can be changed and enhanced.

Let's look at the components of a smile, starting with the teeth. Evenly sized, white teeth are generally considered to be the basis of an attractive smile. Chipped or discolored front teeth can be repaired by bonding tooth-colored composite resin restorations. Thin porcelain veneers can be applied to teeth that are too small, misshapen or discolored. Tooth colored fillings can be used to repair damaged or decayed back teeth, or porcelain crowns may be used to replace the top part of a tooth that has been seriously damaged. If teeth are missing because of trauma or loss due to decay, today they can be replaced by dental implants, topped with crowns that are colored and shaped exactly like the natural teeth.

Of course, if your teeth emerge from inflamed, infected gums, your smile needs improvement. Healthy teeth and gums result from good dental hygiene habits and regular professional dental cleanings and checkups. Teeth can be whitened and brightened both through home methods and in the dental office. Ask us about the options available for tooth whitening.

Another factor that goes into a smile is the relation of the upper to the lower jaw, or the bite. A poor bite is called a malocclusion. Orthodontic treatment, with the use of traditional braces or clear aligners, can move the teeth into a better bite position so that they look and function better.

Repairing parts of your smile that make you feel self conscious will help your smile in more ways than one. If you feel good about yourself, you look better. We get the process started, and you do the rest.

You may have noticed, as you get older, that the enamel of your teeth is looking worn in certain areas. Sometimes tooth wear takes the form of a minor chipping or fracturing at the incisal (cutting) edges of the teeth, or a loss of tooth material from the area near the gum line. In more severe cases, worn teeth look quite a bit smaller than they used to. Why does this happen?

Some wear with age is natural. But too much wear can interfere with your bite, expose more sensitive inner parts of the tooth to decay, and give you a more aged appearance.

There are things you can control that affect wear:

Your habits: Clenching or grinding habits, also called “bruxism,” is a major cause of tooth wear. The motion of teeth sliding over each other with forces that are beyond what's normal for biting or chewing causes a mechanical removal of tooth enamel. This can happen during sleep or periods of high stress. In either case there are therapies available, such as a thin, professionally made mouthguard that prevents your teeth from coming into contact with each other. Holding foreign objects, such as nails and bobby pins, between your teeth can also cause wear.

Your diet: Tooth enamel can be eroded (dissolved away) by acidic beverages, such as sodas, sports drinks and juices. Frequent snacking on sugary foods encourages the growth of oral bacteria that produce acid as a byproduct — also leaving your teeth vulnerable to tooth decay. Your saliva can buffer the effects of the acid in your mouth in about half an hour; if you consume these types of foods and beverages continually, there won't be enough time for this to work.

We can restore the appearance and function of worn teeth in a variety of ways. Porcelain crowns and veneers, for example, can re-establish the normal thickness and length of teeth while improving their color and giving you a more youthful appearance.

   True or False
5. If you do not have enough bone to support a successful dental implant, there is not much that can be done.
   True or False
6. When teeth are missing, the face tends to have a sunken-in appearance called, “posterior bite collapse.”
   True or False

   True or False
8. Dental implants typically cost significantly more than other options, such as a bridge, over the course of a lifetime.
   True or False
9. Dental implants are always more desirable than bridgework or other treatment options for missing teeth.
   True or False
10. Dental implants can lead to improved health due to better nutrition and proper digestion.
    True or False

1. True. Dental implants can appear as beautiful, natural teeth.
2. True. When properly maintained, implants provide the same function as natural teeth roots.
3. False. Dental implants are not suitable for replacing primary teeth or permanent teeth in young children or teenagers. They are best used when facial and jaw development is complete.
4. False. They have a 95% success rate.
5. False. If you do not have enough bone for a dental implant, you may be a candidate for a bone graft — a process in which we “grow” the bone we need for the implant.
6. True. This condition is often totally reversible once teeth have been restored through implants or bridgework.
7. True. Unlike bridgework, dental implants do not affect surrounding teeth.
8. False. They are less expensive in the long run.

When you have your teeth bleached in a dental office, the results almost seem like magic. Let's push aside the magician's cape and see what is really happening in professionally-applied, in-office tooth whitening.

How do teeth become discolored?
A tooth's enamel covering is mostly composed of mineral crystals. At a microscopic level, you can see a framework or matrix of organic (living) matter interspersed between the crystals of enamel creating a very irregular surface capable of retaining stains. Chromagenic (color generating) organic compounds can become part of this organic matrix resulting in tooth staining. They can be bleached without affecting the mineral structure of the tooth's enamel.

As people get older and their teeth wear, the enamel loses its youthful translucency and the underlying layer, called dentin, thickens and becomes more yellow. Such changes to the actual tooth structure are called intrinsic staining. Other causes of intrinsic discoloration are exposure to high levels of fluoride or tetracycline antibiotic administration during childhood, tooth decay, or root canal problems, among others. Discoloration can also be caused by external staining from certain foods, drinks, or tobacco products. Such surface stains are called extrinsic staining.

Behind the Magic
Materials used for tooth bleaching are hydrogen peroxide and carbamide peroxide. Peroxides are commonly used as bleach, and you may have seen them used as hair bleaches, for example. Hydrogen peroxide is a strong oxidizing agent that attacks the organic molecules responsible for tooth discoloration, bleaching them until they lose their color. Carbamide peroxide also contains urea, which is a compound that permits the peroxide to remain in contact with the teeth for longer amounts of time without harming them.

Often called power bleaching, the in-office technique uses a high concentration of peroxide solution (35-45% hydrogen peroxide), placed directly on the teeth in the form of a gel. A heat or light source may enhance the peroxide release. The gel is applied with trays custom fitted to your mouth, and specific barriers are applied to protect sensitive gum tissue from the solution. Results show teeth becoming up to ten shades lighter in about an hour.

In-office bleaching under the supervision of my staff and me is recommended if you have severely stained teeth, and particularly if you are about to have veneers or crowns made. It's a way to rediscover the pearly translucency of your youthful smile.

When you begin a smile makeover in our office, you are embarking on an exciting partnership with my laboratory technician and me. You should be full of excitement and anticipation — if you have been dissatisfied with your current smile, and you have great expectations for the results of this project. You will really like what you see in your mirror.

Being completely satisfied with your new look depends upon successful communication — between you and me and also between my dental lab technician and me. As you might expect, your perceptions of how your teeth appear are different from a dentist's perceptions. My education leads me to think of factors that untrained individuals probably won't consider, such as crown (tooth) length, midlines (how the teeth line up with other facial features) and the distance from gum to lip.

It is helpful to be able to describe what you like and don't like about your current smile, and what changes you would like to see. Using visual aids is a good idea. Bring photos and magazine illustrations to show what you have in mind. (Remember that we cannot make you look exactly like a celebrity or anyone else. The pictures are guidelines.)

Things to think about:

• The color, size, shape, alignment and spacing of your teeth.
• How much of your teeth and gum tissues show when your lips are relaxed and when you smile.
• Tooth color: bright “Hollywood” white or more natural looking off-white.

Your makeover is more likely to meet your expectations if you get an advanced view of the results. Computer imaging is one way to do this. Another is for us to make a mock-up of the proposed dental work in tooth-colored wax on models of your mouth.

Finally, a “Provisional Restoration” can be used as a test to make sure that what I envision is also what you, the patient, want to see. A provisional restoration, made from temporary materials, gives you a chance to test out the changes and make sure they work for you — that they not only look good, but they are also functional in terms of biting, chewing, speech, and gum health.

If the provisional restoration works, it is used as a blueprint to make durable and long lasting porcelains in the same design. We will take impressions of the provisional restoration and communicate the relevant information to a dental laboratory technician, who will make the final porcelain tooth replicas for your new smile.

Competent communication and a provisional restoration will put you on track to meet your expectations and obtain the most aesthetic and functional result in your Smile Makeover.
