If you have discolored teeth, the cause is often staining on the enamel surfaces from foods, beverages, or smoking. But tooth discoloration may also originate deep within the root of a tooth. Sometimes this happens to a tooth that had to have earlier root canal treatment because of injury or decay.
In such cases the living pulp tissue and its blood vessels and nerves had to be removed from the root canals, resulting in the death of the dentin layer, which makes up most of the tooth's body. Over time this caused the dentin to darken. The color may come from remains of blood that was left in the tissue, or from filling materials left in the root canal that are showing through.
Since these stains are caused internally (intrinsic) and not on the outside of the tooth (extrinsic) they must be whitened from the inside. This is usually done by putting a bleaching agent into the empty chamber from which the pulp was removed. Usually the bleaching agent is a substance called sodium perborate.
When it is mixed with a solution of hydrogen peroxide, sodium perborate slowly bleaches the color from the tooth's internal material. It is considered to be safe and reliable for this use.
The work begins by taking x-ray images to make sure that the root canal is correctly sealed and the bone is healthy. After this, we will make a small hole in the back of the tooth through which the root canal space will be cleaned. The root canal space will be sealed and the bleach will be applied in a putty-like form and sealed off from the rest of your mouth. Every few days this procedure will be repeated until the bleaching reaches the desired level.
At this point a tooth-colored composite resin will be used to seal the small hole that was made in the dentin to insert the bleach. After the tooth has reached the level of whiteness that matches it to your other teeth, veneers or crowns must sometimes be used to repair the surface if it is chipped or misshapen, for example.

You may have heard the term “veneer” with reference to woodworking, where it means a thin layer of attractive wood that covers and enhances the surface of a piece of furniture. Exactly the same principle applies to porcelain veneers used in dentistry: A thin layer of ceramic material is used to cover parts of a tooth in order to improve its structure and appearance.
Porcelain is a non-metallic ceramic material that is fired in an oven at a high temperature to make it hard and durable. Dental porcelain veneers are thin layers of ceramic that can be applied to the outside of the tooth so that the end result mimics the natural color and translucency of tooth enamel. The underlying tooth structure has to be prepared by removing a small amount of the enamel, about 1 mm, which the veneer replaces. The veneer is then bonded to the prepared surface using a light-sensitive resin.
In woodworking, a veneer may be used to match the grain between the left and right sides of a piece of furniture, creating a beautiful effect on a curve, or simply to bring the appearance of expensive wood to a backing that is less expensive.
Just as a wood veneer improves the appearance of a dresser or table, porcelain laminate veneers may be used to improve teeth that have a number of cosmetic and functional problems. These include staining that cannot be removed by tooth whitening, teeth that are too small, misshapen, chipped or spaced too far apart. After an assessment of your teeth and your smile, we can create a mock-up using temporary tooth-colored materials so you can decide whether the suggested changes will work for you, or you can make suggestions for further improvements.
Porcelain laminate veneers may not be the best solution for you if your teeth are severely stained or damaged. In cases where a large proportion of the original tooth must be replaced, porcelain crowns may be the best solution. The crown is the part of the tooth that is visible above the gum line, and it can be covered with a porcelain crown that looks exactly like a tooth in shape and color. After studying your needs, together we can decide on the most satisfactory method to restore your most attractive smile.
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.

For a bride, there is so much to remember when planning the wedding — invitations, a dress, flowers, the site, the caterers, the cake, the photographer — the list goes on and on. In the midst of all these things, don't let a very important piece of the plan be forgotten — your smile!
Your wedding will be celebrated every year on your anniversary and commemorated in beautiful photos at any time. It is a special occasion you, your family, and your friends will always remember. But how will you and your family look in those photos? You have an opportunity to get makeovers that will make your smiles shine radiantly, and not only in your album. Your makeover will improve your appearance, your self-confidence, and your oral health far into the future.
Start with a visit to your dentist to assess your current situation and discuss your goals and dreams. Each person's situation will be different. At a minimum you may need a professional cleaning to make sure that your teeth and gums are healthy. Get started on treating any cavities or gingivitis (gum inflammation). If you haven't already, now is a great time to establish healthy dental hygiene habits including proper daily brushing and flossing.
You may feel that your teeth are discolored and need to be whiter and brighter. Your upper and lower jaws may not meet properly for the most effective biting and chewing. Your teeth may be crowded or misshapen. All these things and more can be modified and repaired with today's dentistry.
Teeth can be whitened by bleaching in the dentist's office or with products that can be used at home under a dentist's supervision.
Orthodontia may be needed to repair your bite. Today orthodontia may be done either with traditional braces, or with clear aligners. Remember that this process works slowly, so start well in advance of your wedding day.
After your teeth are properly aligned, your dental team can work on subtle contouring, overall shape and color changes for individual teeth, using techniques such as porcelain laminate veneers. Temporary veneers can be made so that you can try out your new look before the final installation.
Wedding planning works best when started early. To make sure you, your new spouse, and your family look and feel their best, remember to include smile makeovers in your plan.
