Root Decay Treatment

Root decay is the most common long-term disease in older Canadians

Dawson Dental provides Prevora, an antibacterial tooth coating developed and tested for sustained effective root decay prevention.

Root decay is more common than high blood pressure and arthritis, affecting one in three at age 55, and half by age 70. Furthermore, recent studies show a significant association between adult tooth decay and heart disease, stroke and arrhythmia. Your tooth roots are soft and porous, and vulnerable to bacterial attack when they become exposed. This exposure happens gums recede with age or from over-brushing, or because of gum disease. A dry mouth also puts you at risk of root decay.

Fluoride, the most common preventive agent for dental care, remains the choice for preventing decay at the top or crown of the tooth. However, fluoride has proven insufficient to manage root decay.

To fight root decay, studies have shown that it is necessary to reduce the bacterial infection on the root surface for as long as possible.

This antibacterial action is achieved by new painless and topical procedures at your dental office. This procedure is called Prevora and it leaves your teeth in their natural color and takes only a few minutes.

Receding gums
Past the age of 40, our gums begin to recede, exposing the roots, the softest, most vulnerable part of the tooth.


Bacterial attack
Bacteria attack this surface, causing root decay — and once decay starts, it’s hard to stop and may lead to tooth loss.


Penetrating protection
Prevent root decay before it starts! Ask us about Prevora, a painless new sustained-release antibacterial tooth coating that kills the bacteria that cause root decay.


How does Prevora work?

Prevora is a clear, antibacterial coating that contains chlorhexidine, an antimoicrobial compound that, unlike fluoride, readily kills bacteria on your teeth and prevents new bacteria from forming. Studies have shown that chlorhexidine has been used in medicine for many years, and it is has recently been shown to be effective against root decay when it is applied directly to the tooth in the form of a coating. With Prevora, the chlorhexidine chemically bonds with the tooth surface to provide sustained release antimicrobial action.

How is Prevora applied?

Prevora is applied to your teeth quickly and painlessly in a short appointment in the dental office. There is no need for anaesthetic, needles or drills – the coatings are “painted” on with a fine brush in two separate layers.

How safe and effective are these new preventive treatments for root decay?

These new treatments are very safe. The only observed reactions are a temporary coating-sensation on your teeth, some temporary tingling of the gums or tongue, and perhaps a short, bitter taste. They are also very effective. They reduced root decay by 41% over one year in high-risk adults and are the most effective preventive treatments available.

Will Prevora stain my teeth?

No. The treatments leave your teeth in their natural colour.

How often do I need to be treated, if root decay is a chronic disease?

You need to get the infections causing root decay under control. To do so, you need 4 weekly treatments at the start of this prevention, then a single application every recall appointment until you no longer are at risk.

How long does a treatment take?

Approximately 20 minutes.

Will it hurt?

No, the treatments are painless.

Will my dental plan cover it?

We would be happy to submit a predetermination to your insurance company to determine whether you have coverage for this type of procedure.
