Anyone who’s had front teeth dental fillings knows that their appearance plays an important role in lightening up their smile. That’s why the discoloration that gradually occurs in some front teeth fillings causes discomfort for some people who, in turn, look for solutions to whiten fillings on front teeth.
In this blog, we will explore the main causes of discolored tooth fillings and offer solutions to improve the appearance of your front teeth.
What Causes Discoloration in Front Tooth Fillings?
There are many reasons behind the gradual discoloration of your front tooth fillings, including:
- Dietary habits: Some drinks, including coffee, tea, and red wine, and specific foods like berries, beetroot, curry, and tomato sauce, can stain tooth-colored fillings over time.
- Smoking: Tobacco use leaves nicotine and tar, leading to discolored fillings.
- Poor oral hygiene: Failing to brush and floss regularly results in the buildup of plaque and tartar, leading to discolored edges of the filling and internal decay.
- Leaking fillings: After a while, a filling might lose its seal, allowing fluid and bacteria to get through, causing staining and internal tooth damage.
- Secondary decay: If a filling is too old, worn, or has a poor seal, bacteria can infiltrate it and cause decay, creating dark spots or a shadow under the filling.
- Trauma or medications: Dental trauma, some medications, including tetracycline antibiotics, and even fluoride can all alter the visual appearance of fillings.
- Type of dental filling material: Some dental filling materials, including silver sulfide used in amalgam fillings, have a grey-black color that becomes more pronounced over time.
- Aging of the filling material: Amalgam (silver-colored) and Composite (tooth-colored) fillings can darken after coming into contact with staining factors.

Professional Solutions to Treat Discolored Front Tooth Fillings
When seeking professional help with discolored front tooth fillings, doctors usually list a few options that could help your situation. Here’s a list of treatments for discolored dental fillings.
Professional Teeth Whitening
Professional teeth whitening is a safe and effective cosmetic dental treatment designed to remove stains and lighten the color of your teeth. Performed by a dentist, this procedure uses high-quality whitening agents that can brighten your smile by several shades in just one visit.
Unlike over-the-counter whitening products, professional whitening ensures even results and minimizes tooth sensitivity. It’s especially helpful for people whose teeth are discolored from coffee, tea, smoking, or aging. With proper care and regular dental checkups, the results of professional teeth whitening can last for a long time.
Dental Veneers
Veneers are a thin layer of material placed over a tooth to cover any deficiencies and improve its appearance. If your teeth are still in good shape and strong, apart from having small visual defects, dental veneers are the perfect choice because you can keep most of your existing teeth intact.

Dental Bonding
This is the most common procedure for fixing chipped and discolored teeth. As a cosmetic dentistry procedure, dental bonding includes using composite resin materials to help reshape and whiten a discolored and chipped tooth. Tooth binding is one of the most popular treatments in cosmetic dentistry.
Dental Crowns
In this procedure, a tooth-colored crown is placed over the discolored tooth to cover the stained fillings. Dental crowns are not placed over healthy teeth because to place the crown, most of the existing tooth must be removed. Dental crowns are the best option for weak and cracked teeth to improve visual appeal and functionality.
Dental Implants
Used usually as a last resort, dental implants replace the discolored tooth entirely. Before placing dental implants, dentists check to see whether or not you have healthy gums and bone structure, without which the procedure is impossible. Dental implants are cost-friendly, as one can cover a couple of teeth.

At-Home Methods to Improve Appearance
Indeed, no scientific evidence supports the effectiveness of home remedies for professional tooth whitening. However, if you are looking for some solutions to try at home, you may benefit from the following suggestions.
Hydrogen Peroxide
Rinsing and brushing your teeth with products that contain Hydrogen Peroxide can improve your teeth’s appearance and lighten your smile.

Baking Soda
If you mix baking soda with water to form a paste and place it on your teeth for a couple of minutes before washing your mouth, you can improve the appearance of your teeth and kill bacteria in your mouth.
Activated Charcoal
Originally used by ancient Romans, activated charcoal is a home remedy for teeth whitening. However, caution must be exercised while brushing your teeth with charcoal, as it can be very abrasive, and applying too much of it can cause damage.
Lemon
Citrus fruits, especially lemon, due to their acidic properties, can remove stains from the surface of your teeth and act as a tooth whitening agent. To do so, add some lemon juice to baking soda and create a pasty formula to brush your teeth.
