Teeth Whitening: What Works, What Doesn't, and What to Know Before You Start

Teeth change colour over time. Coffee, tea, certain foods, tobacco, and just normal aging all play a part. It happens to everyone, and it’s one of the most common things patients ask about.

There are a lot of whitening options out there, some professional, some over-the-counter, some that make big promises. Here’s a plain look at what’s available and what each option actually does.

Professional in-office whitening

This is done at the dental clinic under your dentist’s watch.

Your dentist applies a high-strength whitening gel to your teeth, sometimes using a special light to activate it. The whole thing is done in a single visit. Your gums are protected throughout.

You’ll see results right away. Teeth can lighten by several shades in one sitting. Because a dentist is watching the process, the strength can be adjusted if you feel sensitivity.

Some people feel a bit of sensitivity for a day or two after. This is normal and goes away on its own. In-office whitening is the most expensive option, but it’s also the fastest and most controlled.

Take-home trays from your dentist

A middle option between professional treatment and doing it yourself.

Your dentist makes custom trays based on impressions of your teeth. You get a professional-grade whitening gel to use at home, following a schedule your dentist sets based on the gel strength and your teeth.

Results build up over time. Because the trays are custom-made, the gel sits evenly on your teeth, which gives more consistent results than one-size-fits-all products.

You do need to be regular with it. Use the trays as directed for the full course. The results are similar to in-office whitening for many people, just slower. If you feel sensitivity, your dentist can adjust the gel strength.

Over-the-counter whitening products

Whitening strips, whitening toothpastes, and rinses are available at pharmacies.

These have lower amounts of whitening agents compared to professional treatments. Strips go directly on the teeth for a set time. Whitening toothpastes use mild abrasives or chemicals to work on surface stains.

These products can help with surface stains, the kind from coffee, tea, and certain foods. They’re not as effective on deeper discolouration or stains that have built up over years.

The results are more subtle. These products are fine for maintenance between professional treatments, but they won’t give you the same level of change as clinic options. If you have sensitive teeth, check with your dentist before using them regularly.

How long do results last

This depends almost entirely on your habits. Someone who drinks black coffee every day and smokes will see the whitening fade faster than someone who doesn’t.

Some general points:

• How long results last varies a lot from person to person
• Cutting down on staining foods and drinks helps keep the results
• Touch-ups from time to time (in-office or with trays) extend the results
• Good daily brushing and flossing makes a noticeable difference

Your dentist can suggest a maintenance plan that works for your lifestyle.

Who is whitening suitable for

Whitening works on natural tooth enamel. A few things to keep in mind:

• Crowns, veneers, and fillings don’t change colour with whitening. If you have visible dental work, talk to your dentist first so there are no surprises.
• Whitening is not done on children. Your dentist can advise when it’s appropriate.
• Active cavities or gum disease need to be treated before whitening. Your dentist will let you know if anything needs to be done first.
• If you already have sensitive teeth, your dentist can suggest an approach that takes that into account.

The best starting point is a conversation with your dentist. They can look at your teeth, tell you what’s realistic, and suggest an approach that fits.

A note on “instant whitening” products

Social media is full of whitening products that promise big results: charcoal powders, UV light devices, whitening pens. Some may work to some degree. Others just make tall claims. Before trying something you found online, it’s worth asking your dentist. They deal with teeth all day and can tell you whether something is worth trying or worth skipping.

If you’re thinking about whitening, start with a consultation. We offer professional teeth whitening at the clinic. Your dentist can look at your teeth and give you an honest idea of what each option will actually do for you.
