A bright smile can boost confidence, but stubborn teeth stains can make teeth look dull. Many people wonder whether teeth whitening treatments can remove deep stains. The answer depends on the type of stain and the teeth-whitening method used. Read on to find out how to remove stubborn stains as well as the best whitening options available.
Types of Teeth Stains and Their Causes
There are two main types of teeth stains:
1. Extrinsic Stains (Surface Stains)
- These stains occur on the outside of teeth on the enamel surface.
- Coffee, tea, red wine, smoking and dark-coloured foods are some of the most common causes of these stain.
- This kind of stain can be prevented and removed by regular brushing and professional cleanings.
2. Intrinsic Stains (Deep Stains)
- The stain occurs within the tooth (dentin).
- Causes include aging, some medications, too much fluoride and trauma to the tooth.
- These stains are more challenging to remove and could need a professional whitening procedure.
How to Remove Brown Stains Between Teeth at Home?
Brown stains between teeth are common and may be caused by plaque buildup, smoking, or drinking dark beverages. While professional cleaning is the best way to remove them, some home remedies may help lighten minor stains.
Home Remedies for Brown Stains:
✔ Brushing with Baking Soda – Baking soda has natural whitening properties that help remove surface stains. Use it once or twice a week for the best results.
✔ Hydrogen Peroxide Rinse – Mix equal parts of hydrogen peroxide and water, swish for 30 seconds, and spit it out. This can help reduce stains and eliminate bacteria.
✔ Oil Pulling – Swishing coconut oil in your mouth for 10–15 minutes daily may help remove toxins and reduce stains.
✔ Using Whitening Toothpaste – Choose a toothpaste with mild abrasives to scrub away surface stains.
✔ Flossing Daily – This helps remove plaque and stain-causing particles between teeth.
Note: If stains persist, professional cleaning may be needed to remove deep discoloration.
Whitening Treatment for Deep Stains
Deep stains inside the tooth require stronger whitening solutions. Professional treatments offer better results than over-the-counter whitening products.
Professional Whitening Options:
- In-Office Teeth Whitening – A dentist applies a high-strength bleaching gel, often activated by light or laser, for immediate results.
- Take-Home Whitening Kits – Custom trays and high-strength whitening gel provide a safe and effective way to brighten your teeth at home in a few weeks.
- Internal Bleaching (For Root Canal-Treated Teeth) – If a tooth has darkened after a root canal, the dentist can place whitening material inside the tooth to restore its colour.
Best Treatments for Stained Teeth
The right whitening treatment depends on how deep and severe the stains are. Here’s a simple breakdown of different options:
- Whitening Toothpaste – Good for surface stains but needs daily use. The results are temporary and work best for mild discoloration.
- Whitening Strips – These are useful for light stains. They take about 1–2 weeks to show results, but the effect usually lasts a few months.
- In-Office Whitening – This is the best option for deep stains. A single session, which takes about an hour, can brighten your teeth significantly. The results can last between 1 to 3 years with proper care.
- Take-Home Whitening Kits – These are recommended for moderate stains. The process takes 1–2 weeks, and results last for 1–2 years. These kits contain whitening gel and custom trays for even whitening.
- Veneers – If stains are too deep for bleaching, veneers are a long-term solution. These thin coverings are placed over the front of your teeth and can last over 10 years with good care.
If you’re unsure which treatment is best for you, a Kitchener dentist can help you choose the right option based on your needs.
