Teeth fillings are used to repair cavities and damage caused by tooth decay. They help restore the function and shape of your tooth. Dentists use different materials for fillings, such as composite resin, silver amalgam, and porcelain. Composite fillings are the most common today because they match the natural color of human teeth.
Why Do People Get Fillings?
Fillings are needed when a tooth has a cavity. Cavities happen when plaque and bacteria break down the enamel. Once a cavity forms, a dentist removes the decay and fills the hole to prevent further damage.
Do Fillings Change Tooth Color?
Fillings do not whiten teeth. They are used to repair the tooth, not to change its color. However, if the dentist uses a tooth-colored composite, it can blend in well with your natural teeth.
Can Fillings Be Whitened?
Many people ask if teeth fillings can be whitened with whitening treatments. The answer is no. Whitening treatments only work on natural tooth enamel. They do not work on filling materials such as resin, porcelain, or metal.
What Happens If You Whiten Teeth with Fillings?
If you use whitening products, your natural teeth may become whiter, but the fillings will stay the same color. This can make fillings stand out. For example, if you have a filling on your front tooth, it may look darker after your natural teeth are whitened.
Options If Fillings Don’t Match
If your fillings no longer match your teeth after whitening, you may want to replace them. Your dentist can remove the old filling and use a new one that matches your whitened teeth.
Types of Fillings and Their Appearance
Composite Resin Fillings
Composite fillings are tooth-colored. They are made of a mix of plastic and glass. These are the most common for visible teeth because they look natural. They cannot be whitened, but they can be replaced to match a new tooth color.
Amalgam Fillings
These are silver-colored fillings made from a mix of metals. They are strong but very visible. Many people today prefer tooth-colored options instead.
Porcelain Fillings
Porcelain fillings are made in a lab and bonded to the tooth. They are also tooth-colored and more stain-resistant. However, like resin, they do not respond to whitening.
Gold Fillings
Gold fillings are durable and can last many years. They are visible and not designed to match tooth color. Whitening does not affect them at all.
How to Maintain White Teeth with Fillings
If you want a whiter smile and have fillings, talk to your dentist first. They can help plan a whitening treatment and may recommend replacing old fillings afterward.
Steps to Keep Teeth White
- Brush your teeth twice daily with fluoride toothpaste.
- Floss once a day to remove food and plaque between teeth.
- Visit your dentist for regular cleanings and exams.
- Avoid staining foods like coffee, tea, and red wine.
- Do not smoke or use tobacco, which can stain teeth.
Should Fillings Be Replaced Often?
Fillings last many years, but they may need to be replaced if they are worn or if you whiten your teeth and want a better color match. Always ask your dentist before whitening if you have old fillings.
Teeth Whitening and Fillings
What Is Teeth Whitening?
Teeth whitening is a cosmetic dental treatment. It removes stains and lightens the enamel. Whitening can be done in the dental office or at home using special kits.
Whitening Products and Their Effects
Most whitening products contain hydrogen peroxide or carbamide peroxide. These chemicals break down stains on natural teeth. But they do not affect filling materials.
Does Whitening Damage Fillings?
Whitening does not harm fillings, but it won’t make them whiter either. This can lead to uneven color. It’s best to whiten teeth first and then get new fillings to match.
Is It Possible to Match Fillings to Whitened Teeth?
Yes, after you whiten your teeth, your dentist can replace your fillings with ones that match your new tooth color. This gives you a more even and natural smile.
When Should You Replace Fillings?
You may want to replace fillings if:
- Your teeth are whitened and the fillings no longer match.
- The filling is old or worn out.
- There are signs of decay under the filling.
How Dentists Replace Fillings
Replacing a filling is simple. The dentist removes the old filling and cleans the cavity. Then, they apply new filling material that matches your tooth color.
Cosmetic Dental Options Beyond Fillings
If you want a more uniform smile, consider other treatments like teeth bonding or veneers. These options can cover the entire tooth and provide a whiter, brighter appearance.
What Is Teeth Bonding?
Bonding uses a tooth-colored resin to repair chips, gaps, or discoloration. It can also change the shape of a tooth. While bonding does not respond to whitening, it can be shaped and colored to match your smile.
What About Veneers?
Veneers are thin covers placed over the front of teeth. They are used for cosmetic changes. Veneers are often chosen for a long-lasting white smile, especially when whitening and fillings don’t give the desired result.
Whitening Before or After Fillings?
It is best to whiten your teeth before getting new fillings. This way, the dentist can match the filling color to your brighter teeth. If you whiten after, the fillings may look darker compared to the rest of your teeth.
How Long to Wait After Whitening?
After whitening, wait about two weeks before getting new fillings. This gives your teeth time to adjust to the final color. Then, your dentist can match the new fillings perfectly.
Common Myths About Teeth Fillings and Whitening
Myth 1: Fillings Can Be Whitened with Bleach
This is false. Whitening gels and treatments do not work on filling material. Only natural enamel can be whitened.
Myth 2: Whitening Will Damage Fillings
Whitening is safe for most people, including those with fillings. However, it won’t make fillings whiter, and sometimes whitening highlights the color difference.
Myth 3: Fillings Always Match Perfectly
Fillings can match very well when first placed. Over time, teeth may stain or change color, but the filling stays the same. This can create visible differences unless fillings are replaced.
Professional Advice for Whiter Smiles with Fillings
Talk to Your Dentist
Your dentist can give you the best advice based on your teeth and filling type. They will check your current fillings, assess your whitening goals, and suggest the right plan.
Get a Custom Whitening Plan
Some people benefit from in-office whitening, while others do better with home kits. A dentist can help you choose. After whitening, you can replace old fillings for a complete look.
Regular Checkups Are Key
Visiting your dentist every 6 months helps keep fillings in good shape and allows early detection of any issues. Keeping your teeth healthy also helps them stay bright and strong.
Conclusion
Teeth fillings do not whiten. They stay the same color even after you use whitening treatments. If you want a whiter smile and have fillings, whiten your natural teeth first. Then, your dentist can replace old fillings with new ones that match. This gives your smile a natural, even look. For the best teeth appearance, always talk to your dentist before starting any whitening plan. Together, you can decide the safest and most effective way to get the bright smile you want.
