What is Cosmetic Dentistry?
Cosmetic dentistry is the art and science of smile design. Almost everyone can enjoy the benefits of cosmetic dentistry. Dentistry has many new materials and techniques that enable me to help my patients improve their self esteem through a more beautiful smile. This article provides a general introduction to some of the latest cosmetic techniques.
Almost everyone wants whiter, brighter teeth. Teeth naturally darken with age. If you are a cigarette smoker or drink a lot of coffee and tea, your teeth are more likely to stain.Extrinsic stains
Bonding is actually a process by which we affix a tooth-colored material (hard plastic) to your teeth, creating a bond. We can use bonding to change tooth color, shape and size, or to repair fractured teeth. We can also use bonding to give the appearance of straight teeth. However, we caution our patients to avoid hard foods, as this may cause the bonded restoration to chip or fracture. A bonded restoration can be polished to look the same as your natural teeth and may also stain in a similar manner as your own teeth. These stains are removed during our patient's regular cleaning appointments by polishing these restorations.
If my patients want something that is more stain-resistant and less likely to chip than bonding, I recommend porcelain veneers. Like bonding, porcelain veneers are also used to change tooth color, shape, and size. We can also use porcelain veneers to give teeth a straighter appearance and to close spaces. Porcelain veneers are thin porcelain shells that are fabricated in a dental laboratory. I often liken porcelain veneers to fake fingernails. We bond the porcelain veneers to the teeth using a special cement. Porcelain veneers are more expensive than bonding since there is a laboratory process involved. I prefer porcelain veneers to bonding when there are several teeth involved because I can achieve a more consistent cosmetic result.
Due to recent technological advances and improved materials, there are now alternatives to silver fillings. I have never had a patient thank me for a silver filling because they like the way it looks. I personally get more gratification and many more thanks from patients when I perform a cosmetic procedure such as tooth-colored fillings. (However, I still place silver fillings in my practice when requested and where cosmetics is not a big concern.) When teeth require smaller restorations, we can fill them in the office with a tooth-colored material (hard plastic) that is bonded to the tooth. If the filling is large, I prefer to use a tooth-colored inlay or onlay, which is custom-fabricated in the laboratory to fit the tooth and is permanently cemented in place. If there is a considerable amount of tooth structure missing, we must crown the tooth.
Porcelain Crowns (Caps)
In my practice, I use both all-porcelain crowns and porcelain-fused-to-gold crowns (a gold crown that is covered by porcelain). I use porcelain to match the shade of a natural tooth. Since more light is reflected in the front of the mouth, I feel that all-porcelain crowns look more natural when restoring front teeth. Crowns are custom-made in a laboratory and are cemented in place.
I work with orthodontists in our practice to straighten teeth, reduce crowding, and close spaces in order to achieve the best possible smiles. Although it often requires a much longer time frame, I often prefer orthodontics over porcelain veneers or bonding. Orthodontics may take at least two to three years to achieve the desired results. Sometimes I find it necessary to use both orthodontics and bonding or veneers to achieve the best aesthetic results.
Sometimes it may be necessary to work with a periodontist (gum specialist) to alter gum tissue to enhance a patient's smile. You may have seen at one time or another a person who will show a lot of gum when they smile, thus limiting the attractiveness of their smile. A periodontist can help correct this problem.
