Composite Fillings
A composite (tooth colored) filling is used to repair a tooth that is affected by decay, cracks, fractures, etc.
The decayed or affected portion of the tooth will be removed and then filled with a composite filling. As with
most dental restorations, composite fillings are not permanent and may someday have to be replaced. They
are very durable and will last many years, giving you a long lasting, beautiful smile.

Reasons for composite fillings:
• Chipped teeth.
• Closing space between two teeth.
• Cracked or broken teeth.
• Decayed teeth.
• Worn teeth.

How are composite fillings placed?
Composite fillings are usually placed in one appointment. While the tooth is numb, Dr. Yu will remove decay as needed. The space will then be thoroughly cleaned and carefully prepared before the new filling is placed. If the decay was near the nerve of the tooth, a special medication will be applied for added protection. The composite filling will then be precisely placed, shaped, and polished, restoring your tooth to its original shape and function. It is normal to experience sensitivity to hot and cold when composite fillings are first placed.  This will subside shortly after your tooth acclimates to the new filling. You will be given care instructions at the conclusion of your treatment. Good oral hygiene practices, eating habits, and regular dental visits will aid in the life of your new fillings.

Why not “silver” fillings?
We recognize the impact of toxic materials and how they can affect general health. We are concerned about the integrity and health of the oral cavity, and we strive to find materials that are systemically compatible and safe for the environment.

In our practice, we do not use any mercury/silver fillings, also known as amalgam fillings. Most people and even dentists don’t realize that these fillings are composed of 50% mercury. It is also important to note that mercury is the most toxic nonradioactive substance on earth, and since 50% of the amalgam composition is mercury we do not feel this restoration is warranted as a dental filling.


Why is it needed?
A crown is a dental restoration that covers or “caps” a tooth to restore it to its normal shape, size, and function. Its purpose is to strengthen or improve the appearance of a tooth.

A crown can:
• restore a tooth when there isn’t enough tooth remaining to provide support for a large fillilng
• attach a bridge to replace the missing teeth
• protect a weak tooth from fracturing
• restore a fractured tooth
• cover a badly shaped or discolored tooth
• cover a dental implant

How is a crown placed?
Several steps are involved and two dental visits generally are needed to complete the treatment. The dentist prepares the tooth by removing its outer portion to accommodate the thickness of the crown. If additional tooth structure is needed to support the crown, the dentist may build up the core of the tooth.

An impression is made to provide an exact model of the prepared tooth. Your dentist or the laboratory technician (following the dentist’s written instructions), then uses the model to help develop the shape and size of the crown.

A temporary cap is placed while the final crown is made. When the crown is ready, the dentist puts it in place and makes the necessary adustments. When you and your dentist are satisfied with how it looks and feels, the crown is cemented in place.

What is it made from?
The look and function of a crown are considered when choosing the material most suitable for you. Your dentist will consider the tooth location, the postition of the gum tissue, the amount of tooth that shows when you smile, the color or shade of the tooth and the function of the tooth.

Crowns are made from several types of materials. Metal alloys, ceramics, porcelain, composite resin, or combinations of these materials may be used. In the process of making a crown, the material often is colored to blend in with your natural teeth.
