Teeth Whitening North York: Achieve a Brighter, Radiant Smile
A bright, radiant smile is one of your most powerful assets, leaving a lasting social and professional impact. However, over time, it is natural for our teeth to lose their luster. If you have noticed teeth discoloration or stubborn tooth staining from coffee, tea, or red wine, you are not alone. At Thornhill Smiles Dental, your premier North York Dental provider, we specialize in high-quality cosmetic dentistry designed to restore the brilliance of your natural tooth enamel. Whether you are preparing for a big occasion or simply want to boost your daily confidence, our professional teeth whitening systems offer a safe, effective, and minimally invasive solution.
Understanding Our Professional Teeth Whitening Process
Many patients try over-the-counter whitening strips or paint-on teeth whiteners before seeking professional help. While these may offer slight improvements, they often lack the strength and precision of clinical treatments. At our dental clinic, we use professional-level teeth whitening products that are far more potent than drugstore alternatives.
Professional teeth whitening works by using a high-concentration whitening gel, typically containing hydrogen peroxide or carbamide peroxide. When applied, this hydrogen peroxide gel breaks down into hydroxy radicals, which penetrate the enamel to dissolve deep-seated stains. This process, often referred to as teeth bleaching, is the most effective way to address teeth discoloration while protecting your underlying dental health.
Take-Home Teeth Whitening Kits in North York
We offer professional Take-Home Teeth Whitening Kits to allow for the convenience of whitening at your own pace. Unlike generic teeth whitening kit options found in stores, our at-home teeth whitening system is customized specifically for you.
- Custom-Made Trays: We take precise impressions of your teeth to create plastic trays (also called custom-made trays) that fit your smile perfectly.
- Professional Whitening Gel: We provide you with a professional whitening gel that is safer and more effective than a standard tray pre-filled with gel.
- Flexible Schedule: You simply apply the gel to your take-home trays and wear them for a prescribed amount of time each day.
These take-home kits are excellent for long-term maintenance and can even be used as touch-up kits.
Specialized Treatments: Vital vs. Non-Vital Whitening
Not all stains are created equal. Our dental techniques allow us to treat two distinct types of discoloration:
- Vital Whitening: This is the most common form, performed on “living” teeth where the staining is on the outer surface or just beneath the enamel.
- Non-Vital Whitening: If you have had a root canal treatment, the tooth may darken from the inside out. In these cases, we perform Non-vital whitening, where the bleaching agent is placed inside the tooth to restore its natural shade.
The Importance of a Personalized Plan
Before beginning any cosmetic treatments, our dentists conduct a thorough review of your dental history and current oral health. It is vital to ensure your dental hygiene is up to date; in fact, we often recommend a hygiene treatment (cleaning) before whitening to remove plaque and tartar, ensuring the gel makes direct contact with the enamel.
It is important to note that teeth bleaching only works on natural teeth. If you have existing dental work such as dental implants, dental veneers, or composite bonding, these materials will not change color. If you are considering a full smile makeover involving porcelain veneers or dental bonding, we usually recommend whitening your natural teeth first so we can match your new restorations to your brightest possible shade.
Teeth Whitening Before and After
Here are some examples of dazzling smiles after teeth whitening:
Managing Tooth Sensitivity
A common concern for patients, especially during our cold-sensitivity-prone winters, is tooth sensitivity. Our professional teeth whitening systems are designed to be as gentle as possible. We offer specialized formulas and desensitizing agents to ensure your dental care remains comfortable. If you have a history of sensitive teeth, our dental team will adjust the concentration of the whitening gel to suit your needs.
Safety and Considerations
At Thornhill Smiles Dental, we prioritize your safety. While professional teeth whitening is considered very safe for most adults, it is typically not recommended for pregnant women or children. During your consultation, we will assess if you are a candidate for whitening or if other cosmetic dental treatments, such as dental veneers, might be more appropriate for your goals.
