A brighter smile is one of the most requested cosmetic improvements — and one of the most achievable. But with dozens of whitening products and treatments available, it can be hard to know which actually works. Here’s a clear breakdown from SmileNOW Dental in Corona, CA.
Why Do Teeth Discolor?
Teeth stain from two main sources. Extrinsic stains sit on the outer enamel surface and come from coffee, tea, red wine, tobacco, and dark-colored foods. These respond well to whitening. Intrinsic discoloration is inside the tooth itself — caused by aging, certain antibiotics (like tetracycline), fluorosis, or trauma. Intrinsic staining is harder to treat with bleaching and may require veneers or bonding for the best aesthetic result.
In-Office Professional Whitening
Professional whitening performed in our Corona office delivers the fastest and most dramatic results. We apply a high-concentration hydrogen peroxide gel directly to the teeth and use a specialized light to accelerate the process. Most patients achieve 6–10 shades brighter in a single 60–90 minute appointment.
In-office whitening is ideal if you have an event coming up — a wedding, reunion, or job interview — and want noticeable results quickly. Results typically last 1–3 years with good oral hygiene and dietary habits.
Take-Home Whitening Trays
We also offer custom-fitted take-home whitening trays with professional-strength gel. These trays are made from an impression of your teeth, so the gel stays in even contact with every surface — something over-the-counter strips can’t achieve. Most patients see full results within 2–4 weeks of nightly use.
Take-home trays are a great option if you want flexibility, a gentler process, or a way to touch up your results over time without returning to the office.
Over-the-Counter Products
Whitening toothpastes, strips, and rinses are widely available but use lower-concentration peroxide or abrasive agents. They can reduce surface staining but rarely achieve more than 1–2 shades of improvement. They also take longer and are more likely to cause sensitivity due to inconsistent fit and overuse.
Who Is a Good Candidate for Whitening?
Whitening works best on natural tooth enamel. It does not change the color of crowns, veneers, bonding, or fillings — so existing restorations may look mismatched after whitening. Patients with sensitive teeth or gum recession should discuss this with Dr. Cruz before starting any whitening treatment. We can recommend a desensitizing protocol to make the process comfortable.
How to Maintain Your Results
Avoid coffee, tea, red wine, and tobacco in the 48 hours after whitening when the enamel is most porous. After that, moderate consumption with good oral hygiene keeps results lasting longer. Touch-up applications every 6–12 months keep your smile consistently bright.
