If you’ve ever scrolled through social media or walked down the dental aisle at your local pharmacy, you’ve probably seen countless teeth whitening products promising a brighter smile.
From whitening strips to LED kits to whitening toothpaste, the options can feel overwhelming. The real question most people ask themselves is: do these products actually work? More importantly, are they safe?
At Love Dentistry in Bellingham, WA, we believe in giving you honest answers backed by science. Let’s break down what dentists want you to know about teeth whitening.
Understanding How Teeth Whitening Works
Teeth naturally become stained and discolored over time due to factors like aging, diet, lifestyle habits, and certain medications. Most whitening products work by using peroxide-based bleaching agents that penetrate the enamel and break down stain molecules. The concentration of peroxide, combined with how long the product sits on your teeth, determines its effectiveness.
Professional whitening treatments contain significantly higher concentrations of peroxide than over-the-counter options. This is why dentist-supervised whitening typically produces faster, more dramatic results. The key difference: dentists can customize treatment to your specific tooth structure and sensitivity levels, which you can’t do with store-bought solutions.
Do Teeth Whiteners Really Work? The Honest Answer
Yes, teeth whiteners do work—but the extent depends on which product you choose. Over-the-counter whiteners can lighten your teeth by one to two shades, while professional treatments can achieve results of three to eight shades whiter. The timeframe matters too: store-bought strips and gels typically show results in two to three weeks, whereas professional treatments often deliver noticeable improvement in a single appointment.
However, not all teeth respond equally to whitening. Yellow-toned teeth typically whiten more easily than gray-toned teeth. Teeth with significant internal staining from medications such as tetracycline may require additional treatments or alternative solutions, such as bonding or veneers.
The Risks You Should Know About
While whitening is generally safe, over-the-counter products do carry some risks worth considering. Overuse can lead to enamel erosion and increased tooth sensitivity. Some people experience gum irritation when the whitening gel comes into contact with soft tissue. And here’s something many don’t realize: whitening doesn’t work on fillings, crowns, or other dental restorations, which means you could end up with uneven coloring.
Professional whitening at our Bellingham, WA practice includes protective measures such as gum barriers and customized trays that help minimize these risks. We also screen for underlying conditions that might contraindicate treatment.

Professional vs. At-Home Whitening: What’s Best?
Professional whitening delivers superior results in less time. You’re under supervision, reducing the risk of damage. Plus, if you experience sensitivity, we can immediately adjust the treatment. Professional results typically last six months to two years, depending on your habits.
At-home whitening is more affordable upfront and convenient. However, results are slower and less predictable. If you choose this route, we recommend consulting with us first to ensure it’s appropriate for your teeth.
- Professional treatments use higher peroxide concentrations (15-35%)
- At-home kits contain lower concentrations (3-10%)
- Professional results appear within days
- At-home results take weeks
- Professional whitening is supervised and customized
Extending Your Whitening Results
Regardless of which method you choose, your diet and habits significantly impact longevity. Coffee, red wine, dark berries, and tobacco can quickly stain teeth. If you’re investing in whitening, commit to maintaining your results.
Simple habits make a difference. Rinse your mouth with water after consuming staining foods or drinks. Use a whitening toothpaste between professional treatments. Schedule regular cleanings—plaque buildup reduces the effectiveness of whitening. And if you’re a smoker, quitting isn’t just good for your teeth; it’s good for your entire health.
