No Worries: Debunking Myths About Professional Teeth Whitening

One of the most prevalent concerns about professional teeth whitening

is the potential damage it can cause to tooth enamel. However, this myth is unfounded. Reputable dental professionals use whitening products that are safe and approved by regulatory bodies, such as the American Dental Association (ADA). These products are designed to whiten teeth without compromising the enamel's integrity.

According to a study published in the Journal of the American Dental Association, professional teeth whitening treatments, when performed correctly by a qualified dental professional, do not cause significant enamel demineralization or erosion. The study concluded that the potential risk of enamel damage is minimal when following the manufacturer's instructions and using the recommended concentrations and application times.

While it is true that some individuals may experience temporary tooth sensitivity during or after a whitening treatment, this is usually mild and short-lived. The sensitivity is often caused by the whitening agents penetrating the enamel and reaching the dentin layer, which contains tiny nerve endings.

Dental professionals can minimize the risk of sensitivity by using lower concentrations of whitening agents and implementing desensitizing techniques, such as the application of potassium nitrate or fluoride gels. Additionally, many modern whitening products contain desensitizing agents that help reduce the likelihood of discomfort.

Another common misconception is that the results of professional teeth whitening are temporary and won't last long. While it's true that the effects of whitening may gradually diminish over time, the longevity of the results largely depends on your lifestyle and oral hygiene habits.

Professionally whitened teeth can maintain their brightness for several years if you avoid consuming staining substances like coffee, tea, red wine, and tobacco products. Regular dental cleanings and touch-up treatments can also help prolong the effects of whitening.

Some people believe that professional teeth whitening is only effective for removing extrinsic (surface) stains and not intrinsic (internal) stains. However, this is not entirely accurate.

While whitening may be more effective on extrinsic stains caused by food, drinks, and tobacco, it can also address some intrinsic stains. These internal discolorations can be caused by factors like trauma, certain medications, or developmental defects. Professional whitening treatments use higher concentrations of hydrogen peroxide or carbamide peroxide, which can penetrate the enamel and dentin layers to address intrinsic stains.

It is a common belief that individuals with dental restorations, such as crowns, veneers, or fillings, should avoid professional teeth whitening. However, this is not entirely accurate.

While it's true that whitening treatments will not change the color of existing dental restorations, they can still be safely performed on individuals with these restorations. The whitening agents used in professional treatments are designed to only affect natural tooth structure and will not harm or discolor existing restorations.

In fact, many dental professionals recommend whitening teeth before receiving new restorations, as it allows them to match the shade of the restorations to the newly whitened teeth, ensuring a seamless and natural-looking result.

The following are relevant ADA (American Dental Association) dental codes for professional teeth whitening procedures:

D9972 - External Bleaching - Office Visit for Bleaching Furnished by the Dentist
This code is used when the dentist applies a bleaching agent to the teeth in the office.

D9975 - External Bleaching for Home Application, Including Materials
This code is used when the dentist fabricates and provides bleaching trays and materials for at-home bleaching.

D9976 - Internal Bleaching (Performed in Office)
This code is used when the dentist applies a bleaching agent inside the tooth to whiten it from the inside.

D9997 - Miscellaneous Procedure, by Report
This code can be used for additional whitening procedures not covered by the other codes, such as combination in-office and at-home whitening treatments or whitening touch-ups.

It's important to note that dental insurance coverage and reimbursement rates for these codes can vary greatly depending on the specific plan and provider. Consulting with your dental office and insurance provider is recommended to understand the costs and coverage associated with professional teeth whitening procedures.
