Can Baking Soda Whiten Crowns?

Can Baking Soda Whiten Crowns?

December 21, 2023

Baking soda, scientifically known as sodium bicarbonate, is a common household product celebrated for its versatility. It's used in baking, cleaning, and even personal hygiene. Among its many uses, baking soda is often touted as a natural teeth-whitening agent. However, when it comes to dental crowns, the question arises: can baking soda effectively and safely whiten them?

Understanding Dental Crowns

To address this question, it's crucial to understand what dental crowns are. Dental crowns are caps placed over a tooth. They're used to restore a tooth's shape, size, strength, or improve its appearance. Crowns can be made from various materials, including porcelain, ceramic, resin, or metal.

Baking Soda For Teeth Whitening

Baking soda is known for its mild abrasive properties, which makes it effective in removing surface stains on teeth. These surface stains are typically caused by foods, drinks, or smoking. The abrasive nature of baking soda helps in gently scrubbing away these stains, leading to a brighter and cleaner appearance of the natural teeth.

The Impact On Dental Crowns

However, when it comes to dental crowns, especially those made of porcelain or ceramic, the scenario is different. These materials are not like natural tooth enamel. While they are designed to mimic the look of natural teeth, their chemical composition is different. Porcelain and ceramic crowns are more resistant to staining compared to natural teeth but are also more susceptible to abrasion.

Using baking soda on dental crowns can be a double-edged sword. Its abrasive quality, while effective on natural teeth, can potentially damage the surface of porcelain or ceramic crowns. This damage might not be immediately visible but can lead to gradual erosion of the crown's surface. Once the glaze on a crown is compromised, it becomes more susceptible to staining, which defeats the purpose of using baking soda for whitening.

Moreover, if the crown has a metal component, baking soda might cause discoloration or affect its integrity. For composite resin crowns, baking soda can wear down the surface over time, leading to dullness and increased porosity, which might make them more prone to staining.

Alternative Whitening Options

For those with dental crowns looking to brighten their smile, there are safer alternatives to consider:

  • Professional Cleaning and Polishing: Regular visits to the dentist for professional cleaning can help maintain the appearance of dental crowns. Dentists use specialized tools and agents that are safe for crowns.
  • Specific Toothpaste: Some toothpastes are designed to be less abrasive and safe for use on crowns. Look for products specifically formulated for artificial teeth.
  • Preventive Measures: Avoiding or minimizing consumption of stain-causing foods and beverages (like coffee, tea, and red wine) can help keep crowns looking brighter.
  • Touch-up Treatments: If the natural teeth around the crowns are discolored, a dentist in Lake Ridge can perform whitening treatments on these teeth, which can indirectly make the crowns appear brighter by contrast.
