Tooth Bleaching Fact and Fiction: Whitening Myths

Tooth bleaching comes with a lot of confident advice, and not all of it is true. Whitening results aren’t permanent without upkeep, crowns and veneers don’t lighten with your teeth, and more product doesn’t mean a better result. On the other hand, some sensitivity after whitening is normal and temporary, and professional whitening can make a real difference for the right teeth. At the Timonium office of Dr. Steven W. Haywood, DDS, whitening is done in the office as laser power whitening, after a consultation about your teeth.

Below, ten common whitening myths are sorted into fact and fiction, followed by how professional whitening works at the practice and what it costs. If you are wondering whether “bleaching” and “whitening” even mean the same thing, start with whitening vs bleaching for tooth discoloration.

Myth 1: Whitening results are permanent

Fiction. This one even shows up in older whitening articles, but teeth keep meeting coffee, tea, red wine and everything else that colors them. The practice’s post-op instructions explain that some rebound, a gradual return toward your original color, is not uncommon, and that it must be managed with careful diet control, meticulous oral hygiene, a whitening toothpaste and periodic repeat whitening in the office. With that upkeep, a bright result can last much longer than it would on its own. Read how to keep a whiter smile after tooth whitening.

Myth 2: Whitening will lighten my crowns, veneers and fillings too

Fiction. Whitening works on natural enamel. Porcelain crowns and veneers, composite bonding and tooth-colored fillings keep the color they were made in. If you have visible dental work on your front teeth, whitening can leave it looking darker than the teeth around it, which is why it is worth planning the order of treatment first. See teeth whitening with crowns, veneers or bonding.

Myth 3: Using more product, or leaving it on longer, works better

Fiction. With store products, going beyond the directions in hopes of a faster result is more likely to bring on sensitivity and irritated gums than a better shade. Professional whitening is effective because of how it is done, not because more is piled on: at the practice, a laser activates the hydrogen peroxide in the whitening agent, significantly increasing the rate and efficacy of the treatment.

Myth 4: Whitening toothpaste does the same job as professional whitening

Fiction. Whitening toothpastes work mainly on surface stains. They are useful for maintenance, and a whitening toothpaste is on the practice’s list of ways to manage rebound, but they aren’t a substitute for professional treatment. The commercial whiteners that seem so promising often fail to deliver lasting results.

Myth 5: Sensitivity means whitening damaged my teeth

Mostly fiction. Pain and sensitivity after whitening are common. The post-op instructions say you may be sensitive to cold air and fluids, and that the discomfort fades within 24 to 36 hours. Sensitivity that lasts longer, or sharp pain in one tooth, is a reason to call, because it may point to a cavity or crack rather than the whitening itself. Read tooth whitening sensitivity and your dentist.

Myth 6: Anyone’s teeth can be bleached to the same bright white

Fiction. Everyone responds differently. Yellowing from surface stains usually responds well, while very dark teeth may only partly lighten, and a single tooth that is darker than its neighbors should be examined before anything cosmetic. If your teeth are very dark, Dr. Haywood will counsel you on your options before you begin, so your expectations match what whitening can do.

Myth 7: Store kits and professional whitening are basically the same

Fiction. They differ in who checks your teeth, how the whitening agent is activated and how long the process takes. Store kits start without an exam. At-home whitening usually means committing two or three weeks. In-office laser power whitening at the practice begins with a consultation, then a thirty-minute whitening treatment followed by a laser for 1 to 2 hours, all under Dr. Haywood’s care. Compare them in professional teeth whitening vs store kits.

Myth 8: You don’t need a dentist to whiten safely

Fiction. Whitening itself isn’t complicated, but deciding whether your teeth are ready for it is. An untreated cavity, receding gums or a cracked tooth can turn whitening into a painful experience, and none of those come with a warning label. That is why every whitening plan at the practice starts with a look at your teeth. For more on safety, read tooth whitening safety: the ADA and your dentist.

Myth 9: Gritty home remedies whiten teeth naturally

Fiction. Scrubbing with gritty powders or pastes can make teeth look cleaner for a moment by polishing off surface stains, but abrasive materials can wear enamel. Worn enamel lets more of the yellow layer underneath show through, which is the opposite of what you want. Ask the team before you try a trend you saw online.

Myth 10: If whitening doesn’t work, nothing will

Fiction. Some discoloration simply doesn’t respond to whitening, but that doesn’t leave you without options. Dental bonding repairs discoloration with tooth-colored composite resin, often in a single visit, and porcelain veneers correct discolored or stained teeth and resist stains better than natural teeth. Prepless veneers can even brighten teeth without whitening for patients who qualify.

The facts about professional whitening at the practice

Here is what is true about whitening at the Timonium office:

• It starts with a consultation. Dr. Haywood looks at your current shade and staining and talks through your goals.
• The plan is customized. Every whitening plan is built around your specific needs.
• It happens in one visit. A thirty-minute in-office whitening treatment is followed by a laser applied for 1 to 2 hours.
• The laser does real work. It activates the hydrogen peroxide and helps dissolve stains, including ones that like to hide.
• Aftercare matters. Avoid colorants for the first 24 hours, and manage rebound over time.

How to tell whitening fact from fiction yourself

When you come across a whitening claim, a few questions help sort it out:

1. Does it promise the same result for everyone? Real results vary.
2. Does it say results are permanent with no upkeep? Rebound is common.
3. Does it skip any mention of an exam? Your teeth and gums matter.
4. Does it suggest your crowns or veneers will whiten? They won’t.

Paying for professional whitening

Your whitening fee is discussed at your consultation. The practice is out of network with all dental insurance providers: you pay at the time of your visit, and the office files the claim so your plan can reimburse you for whatever it covers. Many dental plans treat whitening as cosmetic. HSA and flex plans are welcome for eligible care, and financing is available through CareCredit, with no-interest options up to 12 months, and Cherry, with plans from 3 to 24 months. See financing options.

Frequently asked questions

Is tooth bleaching bad for your teeth?

Professional whitening at the practice happens in the office under Dr. Haywood’s care, after an exam. Temporary sensitivity is common and fades within 24 to 36 hours. Problems such as cavities or receding gums are best found before whitening, not after.

Does laser whitening last longer than other whitening?

How long any whitening lasts depends mostly on your habits afterward. Laser power whitening is designed to give you your brightest smile in the least amount of time, and diet control, good hygiene and periodic touch-ups help keep it.

Can whitening fix a single dark tooth?

A tooth that is darker than the others should be examined first, because the cause may be inside the tooth. Depending on what the exam shows, bonding, a veneer or a crown may be a better fit.

Why do some people’s teeth get whiter than others?

Everyone responds differently. The kind of staining, the thickness of the enamel and any dental work on the front teeth all affect how much brighter teeth become.
