The Bright Future of Teeth Whitening: A Guide to Enhancing Your Smile
By Dr. Neha Gokani, Cosmetic Dentist & Implant Restorative Dentist
Today, I want to answer some of the most common questions my patients have about teeth whitening, a procedure that many find not only life-changing but also empowering. Whitening is often the first step toward improving one’s appearance, and many patients inquire about how best to achieve lasting, natural results. Let’s explore some of the key points and clear up the most frequent concerns.
Does Tooth Whitening Cause Sensitivity?
Sensitivity is a common concern among those considering teeth whitening treatments, and it’s an understandable one. While professional whitening treatments are designed with care, some patients may experience mild discomfort during or after treatment, especially if their teeth are naturally sensitive. This is usually temporary and can be minimized by choosing a treatment tailored to your specific needs. I always ensure that we start with a thorough check-up and clean to ensure the health of your teeth and gums before embarking on any whitening procedure. Using toothpaste designed specifically for sensitivity before, during, and after whitening can help.
How Long Does Whitening Take?
The length of time needed for a whitening treatment depends on the method you choose. In-office whitening treatments typically take about 60 to 90 minutes, offering immediate results with no downtime. Alternatively, at-home whitening kits, which I customize for each patient, typically require a few weeks for optimal results, depending on the strength of the treatment and the frequency of use. The great thing about professional home whitening is that you’ll have personalised trays that fit your teeth precisely, ensuring even and safe whitening.
What Are the Differences Between Office Whitening and Home Whitening?
Both options have their advantages. In-office whitening uses a whitening gel activated by special light, which provides faster, more dramatic results in a single session. This is ideal for patients who want immediate results, especially before an important event like a wedding or photoshoot. I like the ‘Zoom’ Office whitening for this treatment.
Home whitening allows for gradual whitening over time. The process is more flexible and can be done at your convenience, though it typically takes a little longer. But the results tend to be better. With home kits, I provide personalised trays and professional-grade whitening gel to ensure the safest and most effective outcome. For home whitening, I prefer the ‘Enlighten’ brand.
What Concentration of Whitening Gel Is Used?
In the UK, we are restricted to a maximum of 6% hydrogen peroxide for office and home use. For in-office treatments, I use hydrogen peroxide. At-home treatments typically use a lower concentration (of hydrogen or carbamide peroxide) to ensure gradual whitening and minimize the risk of sensitivity.
How Long Does Whitening Last?
The longevity of your whitening results can vary depending on lifestyle factors such as diet, smoking, and oral hygiene. On average, in-office whitening results can last anywhere from 6 months to 2 years. However, with proper care, including regular touch-ups using at-home whitening products, you can maintain a bright smile for much longer. Regular visits to your hygienist and maintaining a good oral care routine are essential for prolonging the effects of whitening.
How White Will My Teeth Go?
The level of whitening you can achieve depends on the natural shade of your teeth and the method used. Teeth whitening can typically remove stains and discoloration caused by age, food, and smoking, but results vary from person to person. While professional whitening can brighten your smile by several shades, there’s a limit to how white your teeth can go. If you’re looking for a natural look, professional whitening will help you achieve a bright, refreshed smile without making your teeth unnaturally white.
Do I Need to Change My Crowns, Fillings, or Veneers?
One of the most common questions I get is whether whitening will affect existing dental work like crowns, fillings, or veneers. Unfortunately, whitening treatments only work on natural tooth enamel and will not alter the colour of dental restorations. If you have crowns or fillings, you may want to consider replacing them after your whitening treatment to ensure a uniform appearance. I always recommend discussing this with your dentist before proceeding with any cosmetic treatments.
How Often Do I Need to Whiten My Teeth?
The frequency of whitening largely depends on your lifestyle habits. If you consume coffee, tea, or red wine regularly, or if you smoke, you may need to whiten your teeth more often. However, many patients find that they can maintain a beautiful smile with occasional touch-ups. For most, professional whitening every 1 to 2 years is sufficient to keep their smile bright.
How Much Does Teeth Whitening Cost?
The cost of teeth whitening can vary depending on the method chosen. In-office whitening tends to be more expensive, typically ranging from £450 to £850, depending on the clinic and the specific treatment. At-home whitening kits are more affordable, with professional-grade treatments costing around £400. While teeth whitening may seem like a significant investment, the benefits of a brighter smile can be life-changing—boosting your confidence and enhancing your overall appearance.
Who Cannot Have Tooth Whitening?
We do not recommend whitening for children under the age of 18 and pregnant or breastfeeding women.
Does Whitening Damage Teeth?
No, as long as it’s done professionally by a dentist or under the supervision of a dental hygienist or therapist. I strongly advise against purchasing whitening products online, as they are prescription-only and may not be safe for use without professional guidance.
Conclusion
Teeth whitening is a fantastic, non-invasive way to enhance the natural beauty of your smile. It’s one of the most popular treatments I offer, and for good reason: it’s quick, safe, and highly effective. If you’re considering whitening, remember that it’s essential to start with a healthy mouth. That’s why I always recommend a check-up and hygiene appointment before beginning any cosmetic treatments.
As a dentist with over two decades of experience, I’ve always believed in the transformative power of a beautiful smile. My journey in dentistry started at Cardiff University, where I followed in the footsteps of my father, a doctor who inspired me to pursue a career in healthcare. After working in mixed practice for the first ten years and transitioning to private practice, I now focus solely on cosmetic treatments and implant dentistry—two areas that allow me to enhance the natural beauty of my patients’ smiles.
The journey hasn’t been without its challenges. Last year, I tragically lost my husband to cancer, and during such a time of immense grief, I found solace in my passion for dentistry. This led to the birth of NG Smiles, a practice dedicated to helping people smile with confidence, no matter their life circumstances. As a testament to the resilience and strength we all carry, I find comfort in the words of Jean de La Bruyère: “Out of difficulty grows miracles.”
