If you've lost one or more of your teeth due to tooth decay, trauma, gum disease or a failed root canal, there are a variety of ways that our office can help you to restore your smile and increase your confidence. Crowns, conventional bridges and dentures aren't your only options for replacing missing teeth. Dental implants, surgically placed below the gums, are another alternative for replacing missing teeth.
Getting Started: If you would like to explore the option of having dental implants to replace one or more teeth, you will first need a comprehensive exam. The ideal candidate for implants is in good general and oral health. Adequate bone in your jaw is needed to support an implant. Smokers and those with uncontrolled chronic diseases like diabetes may not be good candidates for dental implants because healing may be impaired or slow. In addition, dental implants aren't appropriate for children or teens until their jaw growth is complete.
The Process: Dental implant surgery can be performed in our office using either a local or general anesthetic. The implants actually replace tooth roots; they are placed into the bone surgically. Generally made of commercially pure titanium, this metal has the remarkable ability to fuse with the bone as it heals forming a union known as osseointegration (“osseo” – bone; “integration” – to fuse with). This process takes two to six months depending upon many factors of which bone quality is the most important.
The next step is to place an abutment (a small connector) which attaches the implant to the crown. The crown is the part of the tooth that is normally seen in the mouth above the gums.
Assessment of your individual situation and deciding if dental implants are right for you takes knowledge and experience.

One question we are most often asked by parents of athletes or those who participate in physical sports is, “Do mouthguards really work?” And when we respond, “yes,” a common follow-up question is, “Is there any scientific evidence to support this claim?” Based on this scenario, we feel it is important to provide you with some interesting and evidence-based facts on this topic.
The first reported use of mouthguards was in the sport of boxing. And because participants and bystanders in the 1920s quickly witnessed their effectiveness even back then, the trend's popularity grew to the point that boxing became the first professional sport to require them. However, other sports soon started following this lead — especially those high-contact sports. The American Dental Association (ADA) started mandating the use of mouthguards for football in 1962 and the US National Collegiate Athletic Association (NCAA) currently requires mouthguards for football, ice hockey, lacrosse and field hockey. The ADA has since expanded their recommendations to now include 29 different sports and exercise activities. So now that you know more about the professional organizations pushing the use of mouthguards, let's get back to the second question, “What's the evidence?”
There have been numerous studies over the years regarding the properties of mouthguards, and more specifically their shock absorbing capabilities. Other studies have been based upon their protective abilities due to their stiffness, hardness and strength. This research has enabled us to vastly improve upon the effectiveness of mouthguards. For example, years ago latex rubber was a popular material used to create mouthguards. However, today we use products such as ethylene vinyl acetate or polyurethane because they are far superior in durability and flexibility. And impact studies have shown that the chances of fracturing teeth is dramatically reduced when wearing one of these mouthguards...especially when compared to individuals wearing no mouthguard at all. In fact, research has revealed that by not wearing a mouthguard during physical sports or exercise, individuals are 60 times more likely to experience an injury to the mouth and/or teeth.

What causes stains on teeth?
Staining can occur on the outside surfaces of teeth and is caused by foods such as red wine, coffee, and tea, as well as by tobacco use. They can also be developmental, affecting the structure of the teeth due to excessive fluoride levels or from tetracycline antibiotics given during childhood to name a few. Changes in a tooth's enamel or dentin during tooth formation, or as teeth age, can also cause discoloration.
What is going on inside a tooth's structure that makes it look stained?
Most of a tooth's covering (95 percent) is composed of highly mineralized enamel. The crystals of enamel are contained in a framework, or matrix, of organic matter. Dentists believe that various organic compounds that get into this matrix can cause staining.
How do whiteners work?
Tooth whiteners or bleaches expose the teeth to a peroxide compound. This creates reactive oxygen that breaks down highly colored organic compounds within the tooth's sub-surface matrix, making the tooth look whiter, but without changing its internal structure.
What professional in-office whitening techniques are available?
During treatment, a high concentration of peroxide solution in the form of a gel is applied directly on the teeth, often with activation by a heat or light source. These systems use custom tailored trays fitted to an individual's mouth. Silicone barriers or protective gels are used to keep the peroxide gel away from the gums or sensitive membranes in the mouth.
How are professional home whiteners different?
Home whiteners involve a less concentrated solution of peroxide in a gel form. It is delivered to the tooth surface by a bleaching tray that is custom-made in your dentist's office. Over-the-counter whiteners such as whitening strips or paint-on formulas can also be used, but they take longer and they're not as effective — the more diluted solutions are used for safety.
Can toothpastes really whiten teeth?
Mild abrasives in toothpastes clean surface stains but cannot change the underlying tooth color or remove significant staining.
How long do the results last?
Usually, the results last from six months to two years, but effects will diminish over time. You can make them last longer by avoiding the foods and habits that cause staining.
Are teeth whiteners safe to use?
Teeth whitening products are safe if used according to our recommendations or the product manufacturer's directions. Peroxide products may be toxic if used in excess of recommended intervals and amounts.
