Two of My Porcelain Veneers Cracked After a Hygienist Used an Ultrasonic Scaler

Posted by AllSmiles

Both veneers on my upper lateral incisors fractured after three dental cleanings, during which the hygienist used a magnetostrictive ultrasonic cleaner. Is this type of scaler known for fracturing teeth? Why would the hygienist use it? I think the practice should cover the cost of veneer replacement. – Thanks. Kyle

Kyle,

There are two main types of ultrasonic scalers: piezoelectric and magnetostrictive. The most popular magnetostrictive scaler, the Cavitron from Dentsply, is the original ultrasonic scaler and has been used for decades. Though often considered gentler, it requires a higher level of skill and has greater potential to cause damage if not handled correctly. A proficient hygienist should be able to use it without any issues, even on porcelain veneers.

What Are the Potential Risks of an Improperly Used Ultrasonic Scaler?

The incorrect use of an ultrasonic scaler can lead to damage. When a hygienist fails to control the instrument properly, the tip can nick or damage dental restorations, like veneers, and create rough areas on the roots of teeth. These rough surfaces can trap plaque and calculus, which could lead to gum disease or decay over time. Given these risks, we recommend avoiding a dental office where a hygienist has a history of causing such damage.

What Are the Benefits of Magnetostrictive Scalers?

A study published in the Journal of Clinical Periodontology found that while the magnetostrictive scaler took longer to use, it resulted in a smoother root surface compared to the piezoelectric scaler. Patients with porcelain veneers should choose a dental practice that specializes in cosmetic dentistry. Hygienists at these practices receive specialized training on caring for aesthetic dental work.

Choosing a practice with this level of expertise helps prevent future problems and preserve your veneers. Avoiding nicks on restorations and rough areas on tooth roots can protect your investment and maintain long-term oral health.

Ask your dentist about veneer replacement for the damage done during your appointments.
