Need a dental filling? Most people need at least one filling in their lifetime. Many dental fillings last 15 years or more, and those that aredental filling well taken care of — may last longer. Dr. Terence Geary and Dr. Mary Eileen Geary at Geary Dentistry in Brookfield, WI, offers a complete range of dental services. Here are five reasons why you may need a filling.

1. You have a dental cavity.

Dental plaque is a colorless film of bacteria that builds up on the teeth. This acidic substance eats away at the enamel and can lead to cavities. Dental fillings are used to treat cavities. Today, tooth-colored fillings of composite resin are the preferred dental filling available.

2. You have new decay.

In some cases, a dental filling may become loose because decay has developed underneath it. When a dental filling is lost, it is important to contact your Brookfield dentist and have it replaced as soon as possible. Left untreated, a lost filling could lead to loss of the tooth.

3. You have a broken filling.

If your dental filling is broken, see your dentist as soon as possible. Your dentist will replace your broken filling with a new filling. Dental fillings are relatively simple and can be placed in a single appointment.

4. You have a broken tooth.

Chipping a tooth is a common phenomenon. Receiving a blow to the face, falling, or biting down on something hard can cause a tooth to break or chip. If you have a chipped or broken tooth, your dentist may repair the damage with a dental filling. Dental bonding and veneers are also used to restore chipped teeth.

5. You want a great smile.

Cosmetic fillings can improve the appearance of your smile. Cosmetic fillings are the most popular type of fillings, because they blend with natural teeth. Once your dentist completes your fillings, they won't be noticeable when you speak.

If you need a filling, why wait? We can help you today! Call Geary Dentistry at 262-860-1500 today to schedule a dental appointment in Brookfield, WI. We want all our patients to have strong, healthy smiles that look great, too.


It takes a lot of skill, experience, talent and artistry to create tooth restorations that look so natural that no one can tell them apart from the originals. To do so requires understanding of the normal anatomy of a tooth as well as of the interactions of light and color.

How the anatomy of a tooth determines color

The color that we perceive when looking at a tooth results from the combined appearance of the tooth’s center core (dentin layer) and its covering enamel. Going from the outside in, the enamel is made of tightly packed crystals of calcium, which cause it to be one of the hardest substances naturally produced by animals. The crystals are also responsible for a tooth’s brilliance and translucence. The dentin is more like bone, a porous living tissue composed of microscopic tubes, interspersed with more calcium crystals. In the very center of the tooth is a central chamber containing the pulp and nerves.

Each of these layers has its own physical and optical properties. Since the enamel is translucent and the dentin is more opaque, most of the tooth’s color comes from the dentin and is transmitted through the enamel layer. Factors that affect this transmission include the thickness and age of the enamel as well as external tooth whitening.

If the enamel is more translucent, more of the color of the dentin shows through. If it is more opaque, the enamel absorbs and reflects light so that less color is visible and the enamel looks brighter.

The language of color composition and reflected light

Color means the whole spectrum in the rainbow. The spectrum is made up of the three primary colors — red, blue, and green. When all are combined, they create white light.

Hue refers to the brightest forms of the colors. The color we perceive depends on the dominant wavelength of light that is reflected by an object.

Value refers to a color’s lightness or darkness. A brighter color has a higher value.

Chroma is the amount of identifiable hue in a color. An achromatic color (without hue) appears gray.

Saturation is a measure of a color’s intensity.

This terminology of color is used not only by dentists and dental technicians, but also by a wide range of artists. It implies expertise and understanding of how colors work, how they vary and change and affect one another.
