A critical part of effective, daily oral hygiene, flossing removes bacterial plaque from between teeth that can’t be accessed with brushing. Unfortunately, it’s often neglected — string flossing requires a bit more dexterity than brushing and can be difficult to do properly.
It can be even more difficult for people with implants or who wear orthodontic appliances. For brace wearers in particular, getting access to areas between teeth with string floss is next to impossible; the metal brackets and tension wire also have a tendency to catch and retain food debris that’s difficult to remove with brushing alone.
Water flossing, using a device called an oral irrigator, is an effective alternative that addresses many of these difficulties. First available for home use in the 1960s, an oral irrigator delivers pulsating water at high pressure through a handheld applicator that forcefully flushes material from between teeth.
There’s no question that string flossing is effective in plaque removal between teeth — but what about oral irrigators? A 2008 study looked at a group of orthodontic patients with braces who used oral irrigators and compared them with a similar group that only brushed. The study found that five times as much plaque was removed in the group using the oral irrigators as opposed to the group only brushing.
Oral irrigators may also be effective for people who’ve developed periodontal (gum) disease. In fact, oral irrigators coupled with ultra-sound devices are routinely used by dental hygienists to remove plaque and calculus (hardened plaque deposits) in periodontal patients. As with regular oral hygiene, though, it’s important for patients with gum disease to include water flossing with daily brushing (at least twice a day) and regular cleaning sessions at the dentist to ensure removal of all plaque and calculus.
If you’re interested in using an oral irrigator, be sure to consult with us at your next appointment. Not only can we recommend features to look for in equipment, but we can also instruct you on the techniques to make water flossing an effective plaque remover.

While pediatric dentistry has made great strides in making young patients’ dental visit experiences more relaxing, some children and teenagers still have difficulty with anxiety. Their anxiety in turn can make necessary care much harder to provide.
For difficult cases, many dental providers for children now incorporate a technique known as conscious sedation to help ease anxiety. With this technique, they’re able to perform procedures like cavity-filling or tooth-extraction that are more difficult with an anxiety-prone patient.
While general anesthesia creates a total loss of consciousness, conscious sedation uses precise medications to suppress consciousness at different levels ranging from light to deep suppression, and create a relaxed state for the patient. A child under sedation can still breathe normally and respond to certain stimuli, including touch and verbal commands. For only a light or minimal effect, a dentist normally administers the sedation drug as a pill the child takes orally. For deeper sedation, the medication is most likely delivered through a vein (intravenously).
Sedation reduces fear and anxiety but not necessarily pain, so it’s often accompanied by some type of anesthesia, either a local anesthetic delivered by injection to the procedure site or with a nitrous oxide/oxygen gas combination that’s inhaled through a mask worn by the patient.
Even though the child isn’t completely unconscious, one of the dentist’s staff will monitor vital signs (heart and respiration rates, blood pressure and blood oxygen level) throughout the procedure. This continues even after the treatment is over until the child’s vital signs return to pre-sedation levels. Once released, they will need a ride home and should rest for the remainder of the day. They can then return to school and resume other normal activities the next day.
With the advent of newer and safer drugs, conscious sedation is becoming a more widespread technique in both medicine and dentistry. Using it to ease a child’s anxiety increases the chances they’ll receive all the dental care they need without unpleasant memories of their visit that could follow them into later life.

For over a hundred years dental amalgam — a combination of silver, mercury, tin and other metals — has been an effective filling material for teeth damaged by decay. But it has one major drawback — its metallic appearance stands out in stark contrast to the natural color of teeth.
As an alternative, composite resin fillings can match the color, shape and texture of natural teeth. These materials and the techniques used to bond them are proving just as effective as and more aesthetically pleasing than dental amalgam.
Fillings help protect and preserve a decayed tooth. By first removing decayed tooth structure through drilling, the resulting void is filled with durable material that strengthens the tooth and provides it protection from further decay.
The ultimate goal for restoration is to return the tooth to as near normal form and function as possible. Dental amalgam serves well in terms of function, providing the tooth strength in the face of the daily biting forces it encounters. In contrast, composite resins excel in appearance, but haven’t always matched the durability of amalgam. They’re material construction has improved over time, though, as well as the techniques used to bond them to teeth.
Most of these bonding techniques incorporate layering. The first step is to seal the dentin (the porous, living tissue just below the enamel); we then build up the composite material layer by layer within the tooth using special bonding adhesive and curing lights. In some cases where a large volume of tooth structure must be replaced, the restoration is first formed on the tooth and then removed for curing before being cemented into the tooth or a separate restoration is formed by a dental lab.
The end result is a tooth which both looks and functions like a fully intact tooth. Though care must be taken not to subject composite resin restorations to undue forces (no cracking open nutshells, for example), your new filling should continue to serve you and look great for a long time to come.
