Q: Which type of toothbrush should I use?
A: Dr. Williams recommends electric brushes for optimal oral care because patients tend to brush longer, softer, and the brush covers the surface area properly with proper rotations. Dr. Williams recommends the Oral B 6000 and above series electric brush. The brand of manual toothbrush is not as critical as the type of bristle and the size of the head. A soft or extra soft toothbrush with a small head is recommended because medium and hard brushes tend to cause irritation and contribute to recession of the gums, and a small head allows you to get around each tooth more completely and is less likely to injure your gums. It's unnecessary to "scrub" the teeth as long as you are brushing at least twice a day and visiting your dentist at least twice a year for cleanings. For severe recssion, the electric brush with a sensitive head or the Nimbus toothbrush is recommended.

Q: Is one toothpaste better than others?
A: It's advisable to use a fluoride containing toothpaste to decrease the incidence of dental decay. We recommend our patients use what tastes good to them as long as it contains fluoride and is ADA approved. Patients that tend to build up calculus or tartar more should use a tartar control toothpaste such as Colgate Total, patients with sensitivity should use sensitive toothpastes or higher percentage Fluoride toothpastes(Sensodyne),  patients with more staining and no recession should use the whitening toothpastes (Crest 3D White), and patients with gum problems should use the total care toothpastes( Colgate Total or Crest Gum Health). We also prescribe a Calcium/Fluoride containing toothpaste for severe sensitivity or high cavity risk patients.

Q: How often should I floss?
A: Flossing of the teeth once per day helps to prevent cavities from forming between the teeth where your toothbrush can't reach. Flossing also helps to keep your gums healthy. If flossing is difficult, then the use of soft picks, interdental cleaners, or the Waterpik are advised once a day. No matter what, the in between surface of your teeth and gums must be cleaned for optimal health and flossing, the Waterpik, and soft picks are the only way to reach that area

Q: What's the difference between a "crown" and a "cap"?
A: These are restorations to repair a severely broken tooth by covering all or most of the tooth after removing old fillings, fractured tooth structure, and all decay. The restoration material is made of gold, porcelain, composites, or even stainless steel. Dentists refer to all of these restorations as "crowns". However, patients often refer to the tooth-colored ones as "caps" and the gold or stainless steel ones as "crowns".

Q: What's the difference between a "bridge" and a "partial denture"?
A: Both bridges and partial dentures replace missing teeth. A bridge is permanently attached to abutment teeth or, in some cases, implants. A partial denture is attached by clasps to the teeth and is easily removed by the patient. Patients are usually more satisfied with bridges than with partial dentures. Dr. Williams feels that implants are the best way to replace missing teeth since they keep the bone strong, don't require work on neighboring teeth, can't get decay, and are the most like having a natural tooth. We make a temporary removable Valplast for patients while they wait to restore their implants and that has been quite successful.

Q: What about "silver" fillings versus "white" fillings?
A: Although the U.S. Public Health Service issued a report in 1993 stating there is no health reason not to use amalgam (silver fillings), more patients today are requesting "white" or tooth-colored composite fillings. We also prefer tooth-colored fillings because they "bond" to the tooth structure and therefore help strengthen a tooth weakened by decay. While fillings are also usually less sensitive to temperature, and they also look better. However, "white" fillings cannot be used in every situation, and if a tooth is very badly broken-down, a crown will usually be necessary and provide better overall satisfaction for the patient.

Q: Do I need to have a root canal just because I have to have a crown?
A: No. While most teeth which have had root canal treatments do need crowns to strengthen the teeth and to return the teeth to normal form and function, not every tooth needing a crown also needs to have a root canal.
