Cosmetic Dentistry

Dental Bonding is a common cosmetic dental procedure due to its relatively low cost and ease of application. It is often used to reshape or change the color of a tooth and fill in slight spaces between teeth. The composite material used in bonding can be shaped and polished to match all surrounding teeth.

If your smile is in need of a makeover, crowns can provide predictable results. Crowns can give an unattractive tooth back its beautiful shape and color. For smaller or worn down teeth, a crown can restore the natural size of the old tooth. A crown can replace either part of or the tooth's entire structure. For procedures requiring only the areas visible from the outside, a veneer may be an alternative option.

A crown is sometimes termed a "cap" or "jacket." A crown will restore a large filling or a cracked tooth to its original size, shape and tooth color. A crown may be recommended after root canal therapy has been completed, as the tooth tends to become brittle and is more likely to fracture. A crown can strengthen and protect the remaining tooth structure and improves the appearance of your teeth. With the advances in technology, we now have the ability to make ceramic crowns with no metal.

To place a crown, your dentist must reduce 1-2 mm of the tooth to make room for it. Your dentist will then use a piece of thread or cord or use a laser to push the gum down around the tooth, to take an impression of the tooth. The impressions are sent to the lab where the crown is made. During that time, you will have a temporary crown. These crowns are usually made of plastic and are made in your dentist's office on the day of your visit. They are not meant to last. If a temporary crown is left in the mouth, the cement eventually washes out, and the tooth can decay. At a second visit, your dentist will remove the temporary crown and test the permanent one. Sometimes crowns need additional polishing, glaze or some other adjustment before they are placed. Once the crown is ready, it's cemented to your tooth.

Gold Crown

The 'gold' standard. Dental gold is about 60% gold alloy which is meant to match the hardness of the enamel of opposing teeth so both wear about evenly, an important trait.Gold does not tarnish or corrode and has some bacterial inhibiting quality. Gold crowns are strong and will not break. However, gold crowns obviously are not considered esthetic; they are gold colored. So usually gold crowns are used for lower back molars because they don't show there.

The most common type of home teeth whitening involves placing a gel-like whitening solution, which usually contains hydrogen peroxide, in a tray that resembles a Nightguard or mouth guard. Over-the-counter mouthpieces are unlikely to fit correctly and can cause gum irritation if the whitening agent seeps out. The tray is then placed over the teeth for a certain period of time, anywhere from an hour or two to overnight.

Porcelain Fused To Metal Crown (PFM)

The most common type of crown and has a proven track record. PFM crowns are fairly aesthetic and they look like real teeth. However, the margins or borders may appear dark because PFM crowns have a metal substructure with layers of porcelain fired over the substructure. Porcelain is very hard, much harder than natural enamel and may cause excessive wear of the enamel of opposing teeth. Porcelain may break with extreme biting forces.

What is a dental Veneer?

A veneer procedure is a popular cosmetic procedure. Porcelain is known as one of the best materials for esthetic dental procedures, because it mimics tooth enamel very closely. Veneers are extremely thin (usually less than 0.5 mm thickness), giving them enamel-like translucency, creating a natural appearance. They are about as thick as a contact lens. There is very little tooth preparation before the veneer application.

Porcelain veneers are attached to your teeth using a dental bonding glue or cement. Although veneers are very thin, once bonded to your teeth they become strong. The process is fast and conservative. First, your teeth are prepared and impressions are sent to a dental laboratory along with the design for your new smile. Veneers may be recommended along with other cosmetic procedures in order to produce optimum results.

Veneer Procedure Steps:

  1. Your teeth are cleaned so that only your natural tooth is exposed. Old surface restorations are removed.
  2. In some cases the tooth is etched so the veneers will adhere more easily.
  3. An impression is taken of the tooth area where the veneers are to be placed and sent to the lab for fabrication.
  4. When the veneers are ready, your dentist will check the fit along with its future appearance, then permanently bond them to your teeth.
  5. After the veneer is set, it is shaped and polished to look like a natural tooth and fall in line with surrounding teeth.

Veneer Procedure Benefits:

  • You can have your porcelain veneers and a beautiful new smile in as little as just two office visits!
  • Very little tooth alteration to your natural teeth and does not affect neighboring teeth.
  • Gap space between teeth can be closed without the use of braces.
  • Veneers can add tooth length to worn down teeth.
  • Veneers can add tooth shape and thickness.
  • Veneers can cover broken or chipped teeth so that they look like healthy normal teeth.
  • Veneers can renew the color of stained teeth.
  • There is no dark line at the base of the tooth like some dental crowns occasionally have.
  • The porcelain material is stain-resistant for lasting beauty and integrity.

Porcelain Veneers vs. Lumineers

  • Lumineers is a specific brand of porcelain veneers, which use a patented porcelain material known as Cerinate. They are even thinner than traditional veneers.
  • Lumineers require very little or no tooth reduction. They are a great choice if your teeth only need minor changes, to if they are set back slightly.
  • Traditional veneers may be a better choice if you are looking to make more dramatic changes.


There is now new technology that allows you to replace old silver and gold fillings with a more natural looking, composite filling. Composite fillings are bonded to the tooth and research has proven them to be about 90% as strong and healthy as natural tooth material.


Other Benefits:
- Beautiful in appearance
- Completed in a single visit
- No filling leaks
- Less chance of tooth cracking

Looking for Teeth Whitening in San Francisco? Yearning for a bright youthful smile?

Dr. Dokhanchi offers a full range of cosmetic dentistry including professional teeth whitening. Teeth whitening is the #1 requested and performed cosmetic dental procedure. Teeth whitening (sometimes called teeth bleaching) is a procedure that brightens teeth and helps to remove stains and discoloration.

Throughout the day a thin coating of bio film collect on teeth, the bio film can attract stains that can be trapped in the pores of tooth's enamel.

Teeth whitening by a dental professional is key as cavities need to be treated before teeth are whitened. Cavities are problematic because whitening solution can penetrate the cavity allowing decay to reach inner areas of a tooth. People with good dental health may also use a kit to whiten teeth at home. However, in a single office visit, teeth whitening performed by a dental professional will produce brighter results that are more consistent in color across all teeth.


Teeth Whitening - FREE Upon completion of full-fee adult dental exam, x-rays, cleaning and polishing (in the absence of periodontal disease) $495 value - not valid with other offers.

Tooth Colored Fillings

Composite fillings are today's modern filling choice. They are made to match your tooth's natural color to make them virtually invisible to notice and are placed onto the tooth by bonding the filling material to the tooth so they do not have the unlikely chance of falling off. Many patients choose to replace their old silver and gold fillings with composite fillings.


Other Benefits:
- Beautiful in appearance
- Completed in a single visit
- Form a strong seal
- Less chance of tooth cracking
