  • What about amalgam fillings? Are they still used and do you replace existing ones?

We use porcelain or composite fillings for our patients and have for a number of years. Many patients still have amalgam fillings and if and when they require replacement we use the newer alternative materials. The controversy over the years surrounding amalgam fillings is in regards to mercury. It isn’t definitive whether mercury is a true safety concern or if it is harmless. The FDA had said any ties to diseases and autism, Alzheimer’s and MS is unfounded, but more recently has called for stricter regulations without sufficient evidence. In our practice, we take every precaution possible to ensure we meet and exceed safety guidelines and we use porcelain and composite for fillings.


  • If I want to change the shape of my teeth what options do I have?

We can enhance the shape of teeth whether it is to close gaps, repair chipped or cracked teeth or have teeth appear longer. One way is by bonding, applying tooth-colored resin to the tooth surface and then harden it with a special light to “bond” it to the tooth. Crowns are another way to shape teeth. They are basically a cap that fits over the existing tooth, cemented into place and is visible above the gum line. Recontouring is another example of tooth shaping. And then there are veneers, thin translucent pieces of tooth-colored composite or porcelain are used to repair, strengthen and enhance the appearance of teeth. It is ideal for teeth that are chipped, cracked, stained or gapped.


  • What are dental sealants?

Sealant is a thin plastic coating painted on the chewing surfaces of teeth (usually back molars) to protect enamel in the recesses or grooves. Studies have shown over the last two decades that the protective coating decreases tooth decay. This is ideal for children or people who are prone to cavities.


  • Are dental x-rays safe?

The concern people have with x-rays is the exposure to radiation. Keep in mind that x-rays done at a routine dental exam expose a person to very low amounts of radiation, less than a day’s worth of typical background radiation from things like our TVs or spending time outside in the sunshine. Improvements in protective aprons and x-ray equipment allow for much less exposure to radiation than we had decades ago. X-rays allow dentists to see beneath the tooth’s surface and thus are the best diagnostic tool we have for identifying hidden tooth decay and periodontal disease. Uncovering problems before they become bigger is the goal. According to the ADA, how often a patient should have x-rays varies with age and history of tooth decay. The bottom line is that we do not want to do them unnecessarily.


  • Can you just not use the drill?

The drill is used to create an opening and remove decay completely before filling and bonding the cavity. Drills are also used to remove plaque or old fillings. Most people’s fear is associated with the high-pitched sound of the drill and once a dentist begins the procedure, the patient is often able to relax as they soon realize it is harmless.


  • Why is a teeth cleaning and checkup appointment necessary every 6 months?

Regular visits are so important because it is a preventative measure, avoiding problems before they start. We suggest twice a year, but if your teeth are in great condition and your habits are good then you might get by with once a year. We can usually catch small oral health issues before they become big issues. Many diseases and health conditions have symptoms that appear in the mouth so finding them early is essential to overall health.

 Nobody wants stained, yellow teeth so whitening is a great fix. From custom take home trays to Zoom power whitening, the results and costs vary, but many patients find a successful difference after one session. 
 As an alternative to traditional metal braces, we offer custom, removable aligners to straighten teeth, which produce pleasing results.
 We group these procedures together because both ceramic porcelain treatments are custom-made and placed over the tooth to alter or repair discoloration, size, shape and strength. Either can restore a broken tooth, teeth worn down from grinding, crooked teeth and gaps. Each is cemented into place, covering the visible portion of a tooth. Dr. Ellison can help you decide which is best for an individual patient.
 As an alternative to veneers, dental bonding is a quick and simple fix for minor repairs of teeth that are cracked, chipped, misaligned or discolored.
 The new standard for permanently replacing missing teeth. Modern dentistry makes dental implants designed to last indefinitely. These porcelain beauties offer a natural translucency with superior new technology. Replacing the older style bridge, these are metal-free options that can be used as an individual tooth or a group of teeth. 
 Dr. Ellison will consult with patients individually to determine which treatment is the most ideal option.

My daughter has told me before about a recurring dream or nightmare she has, where her front teeth are chipped. She awakens and runs to the mirror in horror to make sure it isn’t true. This fear is actually not too uncommon. While I am not going to attempt to analyze or interpret what that dream might mean, I can tell you some things that may cause chipped, cracked or broken teeth as well as the basics on some solutions should this occur.

Biting on hard things such as ice, hard candy or the like; high-impact sports; accidents; bruxism (clenching or grinding teeth); decay and poor nutrition can all contribute or cause chips, cracks or breaks in teeth. I read a study in the last couple years which indicated around 30% of patients in their 40’s have at least one chipped tooth.

If you have chipped a very small piece of tooth enamel I often do bonding using tooth-colored composite resin. This is a very simple procedure that usually does not even require numbing the tooth. We roughen the surface to make the bonding material stick to it. Then we apply an adhesive and bonding material. We shape it so that the tooth looks natural and then use an ultraviolet light to harden it.

If you break a larger piece of tooth or there is decay present, I may file it and cover it with a crown.  Permanent crowns are either made of metal, resin or porcelain. Metal are the strongest, but resin and porcelain (ceramic) can be made to look like the original tooth. You can explore our website for further detail on bonding and on crown procedures.

If a front tooth is chipped or broken, a veneer is a great option to make the tooth look completely natural again. Veneers are a thin layer of tooth-colored resin or porcelain material. The application process is very similar to bonding, but the preparation is more involved.

Occasionally, a chip or a break on a tooth is large enough to where the pulp is exposed. The pulp is the center of the tooth that contains nerves and blood vessels. Bacteria can enter and create infection. If your tooth hurts or is sensitive to heat the pulp is most likely diseased and could die. If this happens, it needs to be removed to avoid infection. The solution is a root canal. This involves the removal of the dead tooth pulp, cleaning the root canal and then sealing it, which usually requires a crown. Most of the time, root canals are not any more involved or painful than having a cavity filled.

So, while I am unable interpret dreams and tell you the cause of your nightmarish scenario of chipping your front teeth, I am able to shed some light on possible causes and a handful of reasonable solutions if you happen to have a chipped, cracked or broken tooth
