Teeth WhiteningFAQ
Answers to the most common questions about professional teeth whitening — from how it works to what it costs, what it can and can’t fix, and how to maintain your results.
How much does professional teeth whitening cost in NYC?
At Smile Pop, professional in-office whitening starts at $340 for a 30-minute Whitening Refresh and $550 for a 60-minute VIP Whitening session. Both use a custom pharmacy-compounded gel. Take-home whitening products are also available at shop.smilepop.com.
What is the difference between the 30-minute and 60-minute whitening treatments?
Both use the same custom-compounded professional gel. The 60-minute VIP Whitening allows for multiple gel applications, delivering deeper shade lift in a single visit. The 30-minute Whitening Refresh is a great option for touch-ups or patients who want a noticeable improvement on a tighter schedule.
Does teeth whitening hurt?
Most patients experience little to no discomfort during the procedure. Some mild sensitivity in the 24 hours following treatment is possible. Smile Pop uses a custom pharmacy-compounded gel that includes desensitizing agents to minimize post-treatment sensitivity, making our treatments more comfortable than standard professional whitening for most patients.
Why does teeth whitening cause sensitivity?
Whitening gel temporarily opens microscopic pores in the tooth enamel, which can allow temperature changes to reach the inner tooth more easily for a short period. This typically resolves within 24–48 hours. Our formula includes desensitizers to reduce this effect significantly.
How long do teeth whitening results last?
Results from professional whitening typically last 6–18 months depending on your diet and habits. Coffee, tea, red wine, and tobacco are the biggest factors that cause re-staining. Most patients benefit from a maintenance treatment once or twice a year.
Do teeth get yellow again after whitening?
Yes — over time, teeth will naturally accumulate new staining from food, drinks, and aging. Most patients find that periodic Whitening Refresh appointments are enough to keep results looking consistent year-round.
How is professional whitening different from whitening strips?
Over-the-counter strips typically contain 6–10% hydrogen peroxide and require daily use over two to four weeks for gradual results. Professional in-office whitening uses significantly higher concentrations applied under controlled conditions, delivering in one appointment what strips take weeks to achieve — if they achieve it at all.
Are whitening strips safe?
OTC whitening strips are generally safe when used as directed. The main risks are gum irritation from improper placement and increased tooth sensitivity with overuse. They are not as effective as professional whitening.
Can yellow teeth actually be whitened?
Yes, in most cases. Yellow teeth caused by staining from food, drinks, tobacco, or natural aging respond very well to professional whitening. Intrinsic staining from medications or trauma is more difficult to address with whitening alone and may require veneers or bonding for optimal results.
Which teeth cannot be whitened?
Whitening gel only works on natural tooth enamel. Crowns, veneers, bonding, and fillings will not change color with whitening treatment. If your smile includes significant restorations in visible areas, it is worth discussing your goals before booking so expectations are realistic.
Can whitening fix coffee, tea, or wine stains?
Yes — these are among the most common and most treatable causes of tooth discoloration. Professional whitening is highly effective for surface staining from dark beverages and food. Results are typically very satisfying for patients whose main concern is beverage staining.
Can I get teeth whitening if I have crowns or veneers?
You can, but whitening will only affect your natural teeth — not the restorations. If you have visible crowns or veneers in your smile zone, whitening the surrounding natural teeth could create a color mismatch. Discuss your dental history when booking so we can advise on the best approach.
Is teeth whitening covered by dental insurance?
No. Teeth whitening is a cosmetic procedure and is not covered by dental insurance plans.
Can I use my FSA or HSA for teeth whitening?
Teeth whitening performed by a licensed dental professional is generally an FSA and HSA-eligible expense. Using pre-tax dollars can meaningfully reduce your out-of-pocket cost. We recommend confirming eligibility with your FSA or HSA administrator.
How white can my teeth get?
Results vary by person. The shade your teeth can reach depends on your natural enamel color, the degree of staining, and your tooth structure. Most patients see a noticeable difference of several shades immediately after treatment.
Is it worth going to the dentist for teeth whitening?
For most patients who want a significant result quickly and comfortably, yes. The concentration of the professional whitening agent, the controlled application, and the added desensitizers make in-office whitening more effective and more comfortable than at-home alternatives. If you have tried strips without the results you wanted, professional whitening is typically worth it.
How soon before an event should I whiten my teeth?
We recommend whitening at least three to five days before a major event. This gives any temporary sensitivity time to fully resolve. Avoid staining foods and beverages in the 48 hours immediately after whitening while the enamel pores are closing.
What is the most effective teeth whitening method?
Professional in-office whitening consistently delivers the fastest and most dramatic results. A custom pharmacy-compounded gel like what Smile Pop uses offers an advantage over standard off-the-shelf professional products because the concentration and formula can be optimized for both results and comfort.
How do I maintain my whitening results?
Limit consumption of staining beverages or rinse promptly after drinking them. Use a whitening toothpaste for daily maintenance. Book a Whitening Refresh appointment every 6–12 months depending on your habits. Smile Pop carries professional-grade whitening products at shop.smilepop.com for at-home maintenance between visits.
Do you need to be an existing Smile Pop patient to book teeth whitening?
No. Whitening and aesthetics services at Smile Pop are open to all patients — you do not need to be an existing orthodontic patient. Book online at booking.smilepop.com and select Whitening & Aesthetics.
