Frequently asked questions
How much does professional teeth whitening cost in Glendale, AZ?
In-office professional whitening at Glisten Dental Glendale runs $395 to $595 for one session. Custom take-home tray whitening (including the custom trays and starter gel) is $295 to $425. The combined protocol (one in-office session plus take-home touch-ups) runs $595 to $795 and delivers the most significant shade change. Once you have custom trays, refill gel syringes are $40 to $80 for lifetime touch-ups.
How many shades whiter will my teeth get?
Most patients see 4 to 8 shades of improvement with professional whitening. The exact result depends on your starting shade, stain type (surface stains lift easily; internal discoloration from tetracycline or fluorosis lifts partially), and tooth tone. Drugstore whitening strips typically deliver 1 to 2 shades of change — professional whitening produces dramatically more visible results in a single in-office session.
Is professional whitening safe?
Yes, when performed by a licensed dentist with proper isolation of the gum tissue. The peroxide concentrations used in professional whitening (25 to 40% hydrogen peroxide in-office, 10 to 22% carbamide peroxide take-home) have been studied extensively and are safe for tooth enamel when applied correctly. Temporary tooth sensitivity is the most common side effect, typically mild and resolving within 24 to 48 hours.
Why can't I just use whitening strips from the drugstore?
You can, and they work — modestly. Drugstore strips use 3 to 6% hydrogen peroxide, which lifts surface stains but doesn't penetrate enamel deeply enough to address internal discoloration. Strips also don't stay reliably in contact with teeth, leaving some areas under-treated and others (particularly gum margins) over-exposed and irritated. Professional whitening uses 5 to 10x the peroxide concentration with controlled delivery — either in-office isolation or custom-fitted take-home trays.
How long will professional whitening results last?
Results typically last 6 months to 2 years depending on your diet and habits. Coffee, tea, red wine, dark sodas, and tobacco all re-stain teeth over time. Patients who maintain their custom trays at home with a single-day touch-up every 6 to 12 months can keep the whitened result essentially indefinitely — this is the most cost-effective long-term approach.
Will whitening make my teeth hurt?
Some patients experience temporary tooth sensitivity during whitening, especially with the higher-concentration in-office protocol. This is typically mild, resolves within 24 to 48 hours, and can be mitigated with desensitizing toothpaste (Sensodyne Pronamel) for 2 weeks before starting, fluoride rinses, and reduced tray wear time. Severe sensitivity is rare, and Dr. Dawood adjusts the protocol immediately if it happens. We don't push through pain.
Will my crowns or fillings whiten too?
No. Whitening gel only affects natural tooth enamel — it does not change the color of porcelain crowns, composite fillings, veneers, or other dental restorations. If you have visible crowns or fillings in your smile line, whitening will make them appear darker relative to the newly-brightened surrounding teeth. Dr. Dawood will plan around this during your consultation — sometimes whitening first and then matching new restorations to the brighter shade is the right sequence.
Can I whiten my teeth if I'm pregnant or breastfeeding?
We recommend waiting until after pregnancy and breastfeeding. The peroxide in whitening gel is considered unlikely to cause harm, but there are no long-term studies specifically in pregnant and nursing women, so the standard dental recommendation is to postpone elective cosmetic treatment until after delivery and weaning. Oral exams and routine cleanings, however, are safe and recommended during pregnancy.
