Can teeth whitening be done after dental filling?

Can Teeth whitening be done after dental filling ? After performing dental fillings to correct dental imperfections, dentists usually advise patients to be careful with their eating habits and daily oral hygiene. If not properly cared for, the filling can quickly become stained, discolored, and cause serious aesthetic concerns.

With the desire to regain bright white teeth, many people consider teeth whitening but are concerned about any potential effects. So, can teeth be whitened after dental fillings? Can dental fillings and teeth whitening be done together? Don’t miss out on BeDental’s article, as we will help you find specific answers.

What is teeth whitening? Is it good?

Teeth whitening is one of the methods that help remove stubborn stains and discoloration on teeth. In fact, teeth whitening uses oxidizing agents that can penetrate the natural enamel layer of the teeth. When combined with light energy, it creates an oxidizing reduction reaction and releases elemental oxygen.

This elemental oxygen can penetrate the teeth and break the color-producing protein chains. Therefore, after teeth whitening, you will have flawlessly white teeth without damaging the tooth surface.

Currently, there are two popular types of teeth whitening agents: Carbamide Peroxide (at-home whitening) and Hydrogen Peroxide (in-office whitening). Although teeth whitening brings high aesthetic effects, are they really good?

The effectiveness and safety of teeth whitening depend on many factors, especially the current condition of your oral health and the severity of discoloration. Furthermore, the technique and method of teeth whitening will also determine the effectiveness of whitening and removing stains on teeth.

Moreover, teeth whitening is also considered safe for oral health. There have been no reported cases of teeth whitening causing any harm to oral health. The whitening agent only affects the external layer, removing stains without harming the enamel or tooth structure, so you can rest assured.

Why do dental fillings turn yellow?

After getting dental fillings, many customers experience the issue of the filling turning yellow or changing color. Before finding an answer to the question of whether teeth can be whitened after dental fillings, let’s look at some of the causes of the yellowing and discoloration of dental fillings:

  • Fluoride Staining: In many cases, yellowing of dental fillings occurs due to excessive fluoride content in drinking water or toothpaste, which forms a cloudy white layer on the teeth.
  • Food and Beverage Stains: Certain foods and drinks, such as coffee, tobacco, and tea, can affect the color of teeth and dental fillings when consumed excessively.
  • Underlying Dental Conditions: If the dental filling is placed on deep decay or poorly developed enamel that has not been properly treated, there is a risk of the filling turning yellow over time.
  • Improper Oral Hygiene: After dental fillings, it is important to maintain proper oral hygiene practices to prevent any impact on the aesthetics of the filling.

Can Teeth whitening be done after dental filling ? 

Can teeth with dental fillings be whitened? If you have issues like gaps, deep cavities, cracks, or chips in your teeth, dental fillings are the best and most cost-effective option for restoring and enhancing the appearance of your teeth.

However, if dental fillings are not carefully cared for, they can easily become stained, discolored, and cause serious aesthetic concerns, especially in cases where composite or amalgam materials are used. So, can teeth with dental fillings be whitened?

According to experts explaining whether dental fillings can be whitened, it is advised that you should not use teeth whitening products after getting dental fillings.

Teeth whitening products are recommended for healthy teeth and act on the natural tooth enamel. However, these products have no effect on dental fillings and can even pose hidden risks.

Therefore, you should never attempt to whiten your teeth at home after getting dental fillings. If you do so, there is a high chance that the surrounding teeth will appear brighter than the filling. This will make the contrast between the natural tooth and the filling more noticeable, resulting in a significant loss of aesthetics.

In addition, there are cases where teeth whitening products interact with filling materials and cause oxidative reactions. For example, Amalgam fillings can darken or cause sensitivity if whitening products are used.

Dental fillings turn yellow, what is the proper solution?

After learning the answer to the question of whether dental fillings can be whitened, many customers feel lost and unsure about what to do.

If you continue to have yellow stains on your dental fillings, it can affect your confidence in communication. The yellow color of the filling will make it easy for others to notice the flaw in your teeth and the dental intervention.

So, how can you fix the issue of yellow stains on dental fillings when whitening products cannot be used anymore? In fact, there is still an effective solution that you can consider:

Replace the filling

Since it is not allowed to whiten dental fillings, the best solution to address this issue is to replace the filling.

The dental filling procedure is quick, simple, painless, and not too costly, especially if you use affordable materials like composite. You can completely replace the filling when you notice the appearance of yellow stains.

Similar to the initial dental filling procedure, you should seek a reputable dental clinic to have it done. A skilled dentist will carefully remove the old filling without causing any harm to the soft tissues. Then, they will clean and place the new filling without leaving any discomfort, thickness, swelling, or pain.

Additionally, you can also consider replacing the filling with a material that does not change color over time, such as dental porcelain inlay/onlay.

This dental filling technique provides high aesthetic results, good durability, and does not change or turn yellow like composite materials. However, to determine whether your teeth are suitable for porcelain inlay/onlay fillings, you should visit a reputable dentist for a comprehensive examination.

Perform cosmetic porcelain veneers

Instead of constantly replacing the filling, you can also opt for cosmetic porcelain veneers to achieve permanently white and non-discoloring teeth. Porcelain veneers are a simple dental technique that provides beautiful, even, and highly aesthetic teeth with perfect durability.

In addition to preventing the appearance of yellow stains, porcelain veneers are also a long-lasting cosmetic restoration method and the best solution for treating dental conditions and concealing tooth discoloration.

To apply porcelain veneers, the dentist needs to slightly reshape the part of the tooth that has been filled accordingly. Then, they design and create a porcelain shell that fits perfectly over the prepared tooth. The porcelain veneer is designed to match the size and color of the natural tooth 100%, resulting in an extremely natural-looking aesthetic effect.

Small note: Although porcelain veneers are safe and effective, they should not be used with teeth whitening products. If your teeth have yellow or discolored areas, it is recommended to undergo teeth whitening first. After that, you can proceed with porcelain veneers on the filled tooth to ensure a consistent color and maintain aesthetic appearance

Porcelain Veneers

Although cosmetic porcelain veneers are a solution for yellow or discolored fillings, they require reshaping of the natural tooth. This action can be invasive and make the tooth more sensitive than ever. Therefore, in addition to porcelain veneers, you can also consider the technique of bonding porcelain veneers.

In particular, porcelain veneers can also adjust the color of the teeth as desired. The color of the teeth is extremely natural, making it difficult to tell if any dental intervention has been done. After the veneers are applied, the aesthetic results are high and meet the strict requirements of modern cosmetic restorations.

Tips to protect fillings from factors that cause discoloration and yellowing

To avoid the cost of having to replace or apply porcelain veneers to the teeth, you can take careful steps in oral care after filling. This is especially important when using materials that are prone to discoloration and yellowing, such as composite or amalgam.

Here are some ways to protect fillings from factors that cause discoloration and yellowing:

Maintain clean oral hygiene after filling

Oral hygiene plays a crucial role in preventing tooth discoloration. Proper oral hygiene will help alleviate concerns about whether whitening can be done after filling. Specifically, after filling, you can take the following steps to prevent filling discoloration:

  • Brush your teeth regularly twice a day to clean your mouth and prevent the growth of bacteria. Use a soft, small toothbrush to reach between the teeth and avoid causing the filling to chip. Also, brush your teeth in a circular motion and avoid brushing horizontally to prevent damage to the teeth and filling.
  • Use a water flosser to deep clean your mouth. This helps remove food particles that can cause stains on the teeth.
  • Use dental floss to remove food residue when not using a water flosser.
  • Rinse your mouth with saline solution daily, especially after consuming sugary, colored, and tannin-containing foods.

Pay attention to a balanced diet and reduce consumption of colored foods

Food and drinks are also one of the causes of discoloration and can change the color of fillings. Therefore, after filling, you should follow a balanced diet to help maintain the whiteness of the fillings. Keep the following in mind:

  • Include foods that can prevent tooth discoloration, such as green vegetables, cheese, and fruits and vegetables high in fiber.
  • You can also include yogurt in your daily diet as it cleans the teeth well and effectively prevents filling discoloration.
  • Avoid foods that can weaken tooth enamel and cause yellowing and discoloration, such as sugary drinks, coffee, and carbonated beverages.
  • Include foods with high antioxidant content, such as carrots and nutritious seeds, to prevent the appearance of discoloration.

Small note: When drinking colored beverages, you can use a straw to limit contact with the recently filled tooth.
