Lost teeth can cause a host of problems, including a loss of your jaw bone and a collapsing appearance of your face, along with difficulty chewing and speaking.
Clearly, it is important to replace missing teeth as soon as possible. Options for replacement include the more traditional methods and the newest technique — dental implants. We believe that implants are your best choice for the following reasons.
Implants prevent bone loss.
Dental implants are substitute tooth roots. Like the roots of your original teeth, they stabilize the bone into which they extend — but in a different way.
The part of the bone that encases the teeth is called alveolar bone, from the word root meaning “sac.” This bone has a special relationship with the teeth it surrounds. It develops as they first erupt into the mouth. If they are lost, the alveolar bone goes, too. It resorbs, or melts away, giving an impression that the bone, gums, and sometimes the lips are collapsing.
Implants are made of titanium, which has the ability to join biochemically to bone. It takes the place of the original tooth root and prevents resorption.
Implants support adjacent teeth.
Your teeth work in harmony, an all for one, one for all relationship with each other. If one is missing, the remaining teeth will slowly move and shift causing them to receive forces that may not be well received. Losing any tooth increases the pressure on the remaining teeth. Losing a back (posterior) tooth can put pressure on the front teeth and they can be forced out of position. All these movements can change a person's appearance as well as in their ability to speak, bite and chew.
They are easier to clean than “traditional” options.
Fixed bridges are non-removable tooth replacements that attach to adjacent natural teeth. These teeth that are adjacent to the missing tooth have to be cut into small peg shapes on which the bridge is attached. The removal of their enamel may make them more prone to tooth decay and gum disease.
Older replacement methods include removable options such as plastic “flippers” and partial dentures. These replacements rest on the teeth and gums, making the teeth they attach to receive greater pressure causing more mobility. In addition, they exert pressure on the gums, causing additional bone loss and increasing the potential for bone loss on the neighboring teeth.
Full dentures, in cases where all teeth are missing, are kept in place by pressing on the gum tissues. This causes even more pressure on the bone, leading to bone loss and changing facial structures.
They are longer lasting.
Studies have shown that removable partial dentures are replaced about every five years; bridges are only 67% successful at 15 years; and implants are over 95% successful for 20 or more years.
- They are cost effective in the long term.
Because implants last longer than other alternative tooth replacements, they may seem more expensive at first; but they will be cost effective over the long term.

The goal of restorative dentistry is to return the teeth to full form (shape) and function. For years, a key tool for achieving this goal has been through the use of metal amalgams (silver looking dental fillings). However, this technique does have some disadvantages. One is the fact that they can involve removal of healthy tooth structure to retain them. Too much “undercutting” can undermine and weaken a tooth resulting in less resistance to biting forces possibly leading to fatigue fractures and cracked tooth syndrome. Another approach is call “biomimetic” which literally means mimicking life. This approach to dentistry is made possible through the structured use of tooth-like materials such as composite resins. Scientific studies and clinical experience have validated their use as both safe and predictable.
By mimicking life, we rely upon our delicate balance of artistry, experience and expertise to provide you with properly restored teeth that function and wear normally, while appearing indistinguishable from natural teeth. Dental composite are now the most commonly used materials for tooth-colored adhesive restorations and have properties similar to a natural tooth's enamel and dentin. They consist of resin which are plastic and fillers made of silica (a form of glass). The fillers give the composites wear resistance and translucency (see through properties). However, most of the properties of enamel are also mimicked quite well by dental porcelains. Porcelains are a form of ceramic, that are formed by the action of heat. Dental porcelains come in all colors and shades so we can easily and perfectly match the color of virtually any natural tooth. As for longevity, porcelain is typically your best option because it is the closest option in mimicking a natural tooth.

If you are pleased with your smile except for that one front tooth that appears darker, then we have good news for you. Often a tooth appears darker as a result of trauma that may have occurred years ago. Your tooth may need root canal treatment or may have already had root canal treatment in the past. Regardless, you can whiten this tooth via a process called internal bleaching. And as the name suggests, the tooth can be bleached from the inside out. Here's a brief summary of how this entire process works:
- Performing an x-ray exam: The first step is to take a radiograph (x-ray) to make sure that your root canal filling is intact adequately sealing the root canal and the surrounding bone is healthy.
- Making an access hole: To apply the bleaching agent, a small hole will need to be made in the back of your tooth to apply the bleach. However, before doing that, the area must be thoroughly cleaned and irrigated.
- Sealing above the root canal filling: This step is critical to prevent the bleach from leaking into the root canal space.
- Applying the bleach: To obtain the whitening needed, it typically requires between one and four office visits for additional bleaching.
- Applying a permanent restoration: Once your tooth has lightened to the desired color, a permanent filling will be placed over the small hole to seal your tooth's dentin. This is then covered with tooth-colored composite resin (filling material) so that the access hole is undetectable to the naked eye.
