Knowing The Truth Behind Common Dental Filling Myths

1 August 2023 by Gregory Price

When it comes to dental fillings, several misconceptions can cause unnecessary worry or confusion. This may lead to a patient being poorly prepared to make important decisions about their oral health.

Myth: Dental Fillings Cause Sensitivity

Tooth sensitivity is an issue many people experience and various factors can cause it. Before blaming dental fillings for sensitivity, it is important to understand the root causes of this condition. Sensitivity can occur due to exposed dentin, enamel erosion, gum recession, or tooth grinding.

While some individuals may experience temporary sensitivity after getting a dental filling, it is not a direct result of the filling itself. The filling procedure requires the removal of the decayed or damaged parts of the tooth structure before placing the filling material. This process can temporarily expose dentin or irritate nerve endings in the tooth.

Myth: Dental Fillings Weaken Teeth

Contrary to popular belief, dental fillings strengthen teeth by restoring their structure and function. The materials used in modern fillings, such as composite resin or porcelain, provide durability and support to weakened tooth structures.

While some of the tooth needs to be removed during the preparation process for a filling, this is limited to removing the decay and creating a stable foundation for the restoration. The filling material then bonds with the remaining tooth structure, reinforcing it and preventing further decay or damage.

Myth: Dental Fillings Are Noticeable Or Unaesthetic

Gone are the days when dental fillings were noticeable metal amalgams. Modern dentistry offers a range of aesthetic options that closely match the natural shade of your teeth. Dentists have techniques to match filling color with your natural tooth shade seamlessly. They carefully select the appropriate shade, ensuring your dental filling blends with your smile.

Tooth-colored composite fillings have become increasingly popular due to their cosmetic appeal. These fillings provide durability and an aesthetic solution by mimicking the natural appearance of teeth. Composite resin can be shaped and contoured to blend flawlessly with surrounding teeth.

Myth: Dental Fillings Last A Lifetime

While dental fillings are designed to be durable, they are not permanent fixtures in your mouth. What determines how long a filling lasts is a combination of the substance used, the patient's hygienic habits, and the pressure used while biting down. Teeth subjected to heavy chewing forces or those with large fillings may require more frequent monitoring and potential replacement.

Keeping tabs on the health of your fillings requires routine dental exams. At these checkups, your dentist will evaluate the strength and stability of the filling. They may recommend replacing the filling to maintain optimal oral health if any signs of wear, deterioration, or decay are detected.
