Professional teeth whitening in Lakewood, Colorado, delivers a brighter smile safely and effectively. Dr. Dian Li offers both in-office and take-home options to fit your schedule and goals.
Teeth Whitening Explained
Teeth whitening lightens discoloration caused by foods, drinks, tobacco, and natural aging. Professional teeth whitening uses peroxide-based gels that break down stains on the enamel and dentin layers. In-office treatment is applied by a dental team, while take-home kits include custom trays and professional-strength gel for use over several days.
Compared with over-the-counter strips or pastes, professional teeth whitening provides more controlled gel concentration, better fit against the teeth, and guidance to reduce sensitivity.
Benefits of Teeth Whitening
- Noticeable shade improvements in a single in-office visit or over one to two weeks with take-home kits.
- Customized approach that considers existing restorations, gum health, and your goals.
- Even, natural-looking results with minimal risk of uneven color or streaks.
- Options that fit different timelines, including events or gradual brightening.
- Guidance to limit teeth whitening sensitivity and protect enamel.
- Support with whitening aftercare tips to help results last longer.
How Teeth Whitening Works
In-office whitening typically begins with an examination and a shade assessment. Soft tissues are protected, and a professional whitening gel is applied in short, controlled intervals. Some systems use a light to activate the gel, while others work chemically without a light.
Take-home whitening uses custom-made trays that hold the gel close to the teeth while minimizing contact with the gums. Most patients wear the trays for 30–60 minutes per day or overnight, depending on the product and instructions provided. Both options aim to lift stains safely and predictably with oversight from a dental professional.
What to Expect With Treatment
Candidacy is determined during an exam that checks for cavities, gum inflammation, exposed roots, and existing fillings or crowns. Teeth whitening does not change the color of dental restorations, so plans may include timing whitening before new work for the best shade match. Mild, temporary sensitivity can occur, especially if you already have sensitivity.
Results vary based on your starting shade and habits. With good home care, many patients maintain brighter teeth for 6–24 months. Right after whitening, enamel is more receptive to stains. For the first 24–48 hours, it helps to follow these whitening aftercare tips:
- Avoid dark foods and drinks like coffee, tea, red wine, and berries.
- Rinse with water after meals if brushing is not possible.
- Use a straw for dark beverages when you resume them.
- Brush with a non-abrasive, fluoride toothpaste and floss daily.
Frequently Asked Questions
Professional teeth whitening is safe when supervised by a dental team. Gel concentrations and exposure times are controlled to protect enamel and gums. Some patients experience temporary sensitivity, which typically resolves within a few days.
Results can last from several months to over a year depending on diet, habits, and oral hygiene. Avoiding heavy staining foods and drinks, using whitening toothpaste, and scheduling touch-ups extend the results.
Whitening gels do not change the color of existing restorations. If you have visible crowns, veneers, or fillings, timing and shade matching may need to be coordinated so everything blends evenly.
Some patients experience mild, temporary sensitivity during or after treatment. Using desensitizing toothpaste, spacing sessions, and following post-care instructions can help manage it.
Gum health should be evaluated first. If active gum disease is present, treatment may be recommended before whitening to avoid irritation and to achieve better results.
The best option depends on your goals, timeline, sensitivity history, and starting shade. In-office treatment delivers faster results, while take-home kits offer convenience. A consultation helps determine the right fit.
