Does Whitening Toothpaste Actually Work?

Whitening toothpastes can help remove surface and deeper stains over time, but understanding how they work, and what they can and cannot do, will help you set realistic expectations for your smile.

But let's start with the basics, why do teeth become stained in the first place?

What Causes Teeth Staining?

Teeth staining happens for a variety of reasons, and it usually falls into two categories, surface stains and deeper, intrinsic stains.

These stains are often caused by coffee, tea, red wine or smoking, all of which contain pigments called chromogens that cling to the enamel on your teeth. Other contributing factors include ageing, certain medications, and even genetics, which can affect the natural colour of your teeth beneath the enamel.

How Whitening Toothpaste Works

Whitening toothpastes generally work in one of two ways.

Some contain hydrogen peroxide, which brightens teeth through a chemical reaction that breaks down stains on the tooth's surface.

Others use tiny abrasive particles that physically scrub away stains, a bit like gently scrubbing a mark off a plate.

Many whitening toothpastes use a mix of both, though the amount of active ingredient is usually much lower than what you would get with a professional treatment.

Can Whitening Toothpaste Damage Enamel?

This is a common concern. It’s important to know that whitening toothpastes containing abrasives can wear down enamel over time, especially if used too frequently. This can lead to increased tooth sensitivity, particularly to hot or cold foods and drinks.

Once enamel is worn away, it does not grow back, so it is worth being mindful of how often you use these products and choosing a toothpaste with a reasonable abrasiveness level.

Can Whitening Toothpaste Damage My Gums?

Your gums can also be affected by whitening toothpaste, particularly the peroxide-based varieties. Whitening toothpastes containing hydrogen peroxide can cause gum irritation, inflammation, or white spots, especially if the toothpaste comes into prolonged contact with the gum tissue.

If you notice any discomfort, redness or sensitivity in your gums after switching to a whitening toothpaste, it is a good idea to stop using it and speak with your dentist.

Professional Tooth Whitening Options

If you are after more noticeable and longer lasting results, professional whitening treatments are worth considering. Philips Zoom in chair whitening can give you maximum results in minimum time.

We offer both in office laser whitening, which delivers instant results, or home whitening to use in the comfort of your own home. Both options are safe and effective for removing stains and discolouration, helping to brighten your smile.

Philips Zoom In Chair Whitening

The process: This treatment is carried out by a dentist in our clinic. A whitening gel is applied to your teeth and activated using laser technology, delivering instant results.

Results: Many patients notice a significant improvement in the brightness of their teeth immediately after treatment, often several shades lighter.

Best for: Those wanting fast, dramatic results, or anyone who prefers the whitening process to be managed entirely by a dental professional.

Philips Zoom Take Home Whitening Kit

The process: This option involves custom fitted trays made specifically for your teeth. You apply a professional strength whitening gel at home over a period of time, following your dentist's guidance.

Results: Results build up gradually, and many patients achieve a similarly noticeable improvement to in chair whitening, just over a longer timeframe.

Best for: Patients who prefer a more flexible approach, or who want to touch up their results periodically after their initial treatment.

In Summary

Whitening toothpaste can be a helpful part of your oral care routine, particularly for managing surface stains from everyday foods and drinks. However, it is generally not strong enough to deliver the dramatic results many people hope for, and overuse can sometimes cause sensitivity or irritation.

If you are looking for a brighter smile with more predictable and noticeable results, a professional whitening treatment, whether in-chair or take-home, is likely to be a better fit.
