Zoom whitening vs whitening strips: which is better?

Which works better: Zoom whitening or strips?

In-office whitening like Zoom gives the biggest change in the least time, usually one visit of about an hour. Strips can also whiten, but they work slowly over days and cover mostly the front teeth. If you want fast and even results, the dental office is the better pick.

If you want a low-cost, slow and steady option and your teeth and gums are healthy, strips can be a fair start. Research shows both in-office and at-home whitening change tooth color. The difference is in speed, fit and supervision.

There is a third choice too: custom take-home trays made by your dentist. They sit between strips and an office visit. They fit your teeth, use a gel your dentist selects and let you go at your own pace. Many people like them for touch-ups.

How each one works

Zoom is a professional whitening treatment. In the office, the dentist protects your gums, applies a whitening gel to your teeth and activates it. Our visit takes about one hour. Your dentist watches how your teeth respond the whole time.

Strips are thin plastic films coated with a weaker gel. You press them on your teeth, leave them on for the time on the box, and repeat daily for a stretch of days. Most boxes ask for use over one to two weeks, so read yours. Whiteners that you buy in a store use lower strengths than a dentist uses.

Strength is the key difference. Professional gels have a higher concentration of peroxide (the active whitening ingredient) than store-bought strips. A stronger gel works faster, which is why your dentist protects your gums and watches the time. Strips use a lower strength so they are safer for people to use alone, but they need more days.

Peroxide breaks stain molecules into smaller pieces that no longer reflect dark color. The gel does not scrub or scrape your teeth. This is true for strips, trays and office treatment alike.

Speed and how much change you can expect

A research review on professional whitening found that both in-office and at-home methods lighten teeth well. In-office treatment does it in one visit. Strips take longer to get close, and some people stop before the end because it is a daily chore.

How white you get also depends on your starting shade. Yellow stains lift easily. Gray tones lift slowly. A dentist can tell you what to expect before you spend a cent.

Think about the time you spend, too. Strips mean a daily habit for a week or two. You also have to stay clear of food and drink during wear time. An office visit moves all the effort to one afternoon, which is a relief for busy people.

Results are not a straight comparison between brands, since strength and wear time change from product to product. That is another reason to ask a dentist, who can match the plan to your teeth.

Even color vs patchy color

Strips are flat, and your teeth are not. Crowded or curved teeth may not touch the strip, so some spots stay darker. Strips also cover the six to eight front teeth at best. If your smile shows more teeth, the back ones can look a shade darker.

Gel in custom trays or applied by a dentist reaches every tooth surface. That gives a more even look, especially if you smile wide.

If you have a gap, a crooked tooth or a tooth that sits behind its neighbors, strips are even less likely to give an even result. You can end up with a smile that looks lighter in the middle and darker on the sides, which looks odd in photos.

Sensitivity and gum safety

Any whitening can cause sensitivity. Studies found a similar risk with in-office and at-home treatment, and that desensitizing products help without lowering results. The best way to stay comfortable is a plan that fits your teeth.

Strips can slide and touch your gums, which can leave them sore or white for a short time. In the office, your dentist covers your gums first. If you have sensitive teeth, ask about it before you start.

One more difference is information. If you feel pain with strips, you are on your own. In the office, you can tell your dentist right away and they can adjust, stop or protect the area. That feedback loop is a real safety benefit for people with sensitive teeth.

What only a dental exam can check

Whitening is not right for every mouth. A quick exam can catch things that strips cannot:

It also helps to get your cleaning first. Plaque and tartar block gel from reaching the tooth, so stains under them stay put and leave you with a spotty result. Many people see a better shade from a cleaning alone, before any whitening starts.

Finally, your dentist can tell you if what you see as yellow is really stain. Sometimes the cause is thin enamel or the natural color of the dentin under it, and that changes what whitening can do for you.

• Cavities or cracks, which hurt badly with whitening gel
• Gum disease or gum recession, which make teeth more sensitive
• Crowns, veneers and fillings that will not whiten and may need to match later
• Dark stains that come from inside the tooth, not from food or drink
• Plaque and tartar that make color look uneven

How to choose

Choose the dental office if you have an event soon, want even results, have sensitive teeth or have dental work in your smile. Choose strips if you want to test the waters, have healthy teeth and gums, and can stick to a daily plan.

Many people start with a dentist visit, then keep results up with take-home trays. A dentist can also tell you if whitening is the right step before bigger work like veneers.

Cosmetic treatments like whitening are usually not covered by dental insurance, according to Cleveland Clinic. Ask us what your plan covers and about financing for larger plans.

Think about your timeline, too. If your event is in three days, a one-hour visit is the safer bet. If you have a few weeks and a tight budget, strips or trays can still get you there. Whatever you choose, do not start whitening on the day before you need to look your best. Give yourself a few days in case your teeth feel sensitive.
