Request an AppointmentWhy Professional Teeth Whitening Works Better
Store-bought whitening strips and toothpastes contain low concentrations of bleaching agents and are designed for minimal change over a long period of time. Professional whitening at Nima Aleagha DDS uses prescription-strength whitening agents applied or dispensed under dental supervision, delivering faster, more dramatic, and more even results — without the guesswork.
We offer multiple professional whitening options to fit different timelines, budgets, and desired outcomes. Our team will evaluate the cause and degree of your discoloration and recommend the approach most likely to give you the results you are looking for.
What Causes Tooth Discoloration?
Tooth staining generally falls into two categories:
Extrinsic staining affects the outer surface of the enamel and is caused by:
- Coffee, tea, and red wine
- Dark-colored foods such as berries and tomato sauce
- Tobacco use (smoking or chewing)
- Poor oral hygiene and plaque buildup
Intrinsic staining originates inside the tooth and may be caused by:
- Certain medications (especially tetracycline antibiotics taken during tooth development)
- Fluorosis from excess fluoride exposure during childhood
- Dental trauma or nerve damage
- Natural aging, which causes enamel to thin and the yellowish dentin beneath to show through
Professional whitening works best on extrinsic staining. Intrinsic discoloration may require alternative cosmetic treatments such as porcelain veneers or dental bonding. During your consultation, our dentist will determine which type of staining you have and what approach will deliver the best outcome.
In-Office Whitening Options
Nima Aleagha DDS offers in-office professional whitening treatments that deliver results in a single visit. We also offer take-home whitening kits using custom-fitted trays designed specifically for your teeth, which provide more controlled and even coverage than generic strips. See our dedicated pages for Zoom!® whitening and Day White® take-home whitening for full details on each system.
Is Teeth Whitening Safe?
When performed or supervised by a dental professional, teeth whitening is safe and well-tolerated by most patients. Some patients experience temporary tooth sensitivity during or after treatment, which typically subsides within 24 to 48 hours. We take precautions to protect your gums and soft tissue during in-office treatment and provide guidance on managing sensitivity with take-home kits.
Whitening is not recommended for patients with untreated cavities, gum disease, or certain types of dental restorations. Before beginning any whitening treatment, we will perform an oral health evaluation to make sure it is the right choice for your situation.
How Long Do Whitening Results Last?
Results from professional whitening typically last one to three years depending on diet and lifestyle habits. Avoiding staining foods and drinks, not smoking, and maintaining good oral hygiene will extend the life of your results. Touch-up treatments can be done periodically to maintain the brightness of your smile. Routine professional dental cleanings also help keep surface stains from building up between whitening sessions.
Frequently Asked Questions About Teeth Whitening
How many shades whiter can I expect my teeth to get?
Results vary depending on the degree and type of staining. Most patients see an improvement of three to eight shades with professional whitening. During your consultation, our dentist can give you a realistic expectation based on the current shade of your teeth and the type of discoloration present.
Is professional whitening better than whitening strips from the store?
Yes. Professional whitening uses higher-concentration bleaching agents under dental supervision, delivering faster and more noticeable results. Custom trays or in-office application also ensure more even coverage than generic over-the-counter products.
Will teeth whitening work on crowns, veneers, or fillings?
No. Whitening agents only affect natural tooth enamel. Existing restorations such as crowns, veneers, and composite fillings will not change color during whitening. If you have visible restorations in your smile zone, our dentist will discuss this with you so your treatment plan accounts for color matching.
Does teeth whitening cause permanent sensitivity?
No. Sensitivity during or after whitening is common but temporary, typically lasting 24 to 48 hours. We provide desensitizing products and guidance to minimize discomfort. Patients with pre-existing sensitivity may benefit from a modified whitening protocol or desensitizing treatment beforehand.
Am I a good candidate for professional teeth whitening?
Most patients with healthy teeth and gums are good candidates for whitening. It is most effective on extrinsic (surface) staining from food, drink, and tobacco. Patients with untreated decay, gum disease, or severe intrinsic staining may need alternative cosmetic solutions. A brief evaluation at our Thousand Oaks office will confirm the best approach for you.
What is the difference between Zoom!® and Day White®?
Zoom!® is an in-office whitening system that delivers dramatic results in a single appointment using a high-powered light to accelerate the whitening process. Day White® is a take-home system using custom trays and professional-strength gel that you apply for short intervals each day. Both are effective — the right choice depends on your timeline and preference.
How do I maintain my whitening results?
Avoid staining foods and beverages, do not use tobacco, brush twice daily, and keep up with regular professional cleanings at Nima Aleagha DDS. Periodic touch-up treatments — either in-office or with take-home trays — will keep your smile looking its brightest long-term.
