If you ever get out of the habit of daily brushing and flossing, you’re setting yourself up for dental disease. Neglecting oral hygiene allows bacterial plaque to build up on tooth surfaces, which can give rise to aggressive gum infections known collectively as periodontal (gum) disease.
Gum disease may first manifest itself as gingivitis, an inflammation of the outer gum tissues around teeth. Resuming hygiene habits could help reduce the infection if it’s detected early enough. If the infection has spread deeper below the gum line, though, brushing and flossing won’t be able to reach and remove the offending plaque — you’ll need our help with that.
The objective of any such treatment is the same as your daily brushing and flossing — remove plaque as well as hardened deposits (calculus) that cause disease. The most basic technique is called scaling in which we use specialized hand instruments (scalers) or ultrasonic equipment to loosen and remove the plaque and calculus from all tooth and gum surfaces.
For deeper plaque, we may need to use a technique called root planing. As its name implies, we use equipment similar to scalers to shave or “plane” plaque, calculus, bacteria or other toxins from the roots that have become ingrained in their surfaces.
These procedures are often carried out with local anesthesia to ensure patient comfort and allow us to be as meticulous as possible with plaque and calculus removal. It’s imperative that we remove as much plaque and calculus as possible, and which often involves more than one session. This is because as the gum tissues become less inflamed it allows us to access more plaque-infested areas during subsequent sessions.
Hopefully, these techniques will arrest the infection and restore good health to gum tissues. It’s then important for you to recommit and follow through on a renewed daily hygiene regimen to reduce the chances of re-infection that could lead to more serious problems and potential tooth loss.

Dentures, removable restorations for missing teeth and gum tissue, can take a number of different forms, but are usually of two different types: complete and partial. A complete denture replaces all the teeth in a given arch. A removable partial denture (RPD), on the other hand, replaces several missing teeth while using the remaining teeth as support.
A common type of RPD formed of plastic is known as a “flipper” because it’s lightweight enough to be “flipped out” or moved around with the tongue. They serve an important purpose as a temporary appliance for use between periodontal treatment, implant placement and similar treatments before obtaining a more permanent restoration. In fact, they’re often referred to as “transitional” RPDs because they’re not designed for permanent tooth replacement.
Because of their low cost relative to other restorations, however, they often become the permanent choice for many people. While a well-constructed, properly fitting RPD in a healthy mouth can be an affordable alternative for people on modest budgets, their long-term use may increase the risk of dental disease and accelerated bone loss. Decades of research verify that people who permanently wear RPDs encounter more tooth decay and periodontal (gum) disease than non-wearers.
This is because the attachment points of a plastic RPD to remaining teeth increases bacterial growth, which can cause both tooth decay and gum disease. This doesn’t only endanger the survival of the remaining teeth, it can lead to bone loss that will affect the RPD’s fit.
While the better course is to consider RPDs as a stepping stone to dental implants or a fixed bridge, there’s an intermediary RPD constructed of cast vitallium or gold alloy that could be considered a permanent choice. These are even lighter weight than plastic and less obtrusive in their attachments in the mouth, which can reduce plaque stagnation and promote a better oral environment.
Regardless of your choice in dentures, it’s always important to maintain good consistent oral hygiene with daily brushing and flossing and semi-annual professional cleanings and checkups. Keeping a healthy mouth will help reduce your risk of dental disease and increase your satisfaction with your denture of choice.

One of the most widely used forms of dental imaging is the bitewing x-ray. So called because of the shape of the device that holds the exposable film a patient clenches between their back teeth, the bitewing x-ray is an effective means for detecting the earliest stages of tooth decay.
These early signs are small lesions on a tooth surface caused by mineral loss in the enamel. While we can identify them on front teeth through visual examination or bright lighting, they’re nearly impossible to see on the biting surfaces of back teeth. The bitewing x-ray solves this problem.
During the procedure, a narrow beam of x-rays is directed at the back teeth area. Since X-rays can transmit through solid matter, they pass through the teeth and gums to expose the film attached to the bitewing assembly.
X-rays pass through matter at different rates depending on the density of the tissue — a slower rate for harder tissues like teeth and bone and a faster rate for soft tissues like the gums. As a result, x-rays through teeth expose less of the film and appear as a lighter image than the gums. This difference is so precise even a tooth’s softer dentin appears slighter darker than its harder outer enamel.
This precision helps us identify decay lesions. Because the lesions on the enamel are less dense than the normal enamel, they’ll appear as dark spots. By detecting them at this stage we have a better chance for reversing the effects of decay or at least minimizing damage that’s already occurred.
Because x-rays emit radiation, there’s a natural concern about over-exposure and we go to great lengths to reduce it. Children may undergo a bitewing x-ray twice a year for developing teeth, while adults with healthy teeth are typically x-rayed just once a year. Advances in digital film and other technology have also helped lower the exposure rate.
Today’s standard 4-film bitewing x-ray produces about four days worth of what we receive on average from normal background radiation, so the health risk is quite negligible. The benefit, on the other hand, is much greater — the early detection of tooth decay could ultimately save a tooth.
