Professional teeth whitening uses a controlled concentration of a peroxide based gel to break down stains within the enamel, typically lightening teeth several shades in a single session or over a short course of at home trays. Over the counter whitening products can help too, but they generally work more slowly and produce far more modest results than professionally supervised treatment.
Key takeaways
- Whitening works by breaking down stain particles within tooth enamel.
- Professional treatment uses stronger, carefully controlled concentrations.
- Results vary depending on the type and cause of discolouration.
- Good habits afterwards help whitening results last longer.
How Does Teeth Whitening Actually Work?
Whitening gels contain a peroxide compound that penetrates the enamel and breaks apart the pigmented molecules responsible for staining. As these molecules are broken down into smaller, less visible particles, teeth appear noticeably lighter and brighter over the course of treatment.
This process does not remove enamel or physically alter the structure of the tooth. It simply changes how light reflects off stained particles within it, which is why whitening is considered a cosmetic rather than a structural treatment.
What Is the Difference Between In Office and At Home Whitening?
In office whitening uses a higher concentration gel, often activated with a special light, allowing results to appear within a single appointment. At home whitening kits provided by a dentist use custom fitted trays and a lower concentration gel worn for shorter periods over one to two weeks.
Both approaches can be effective, and the right choice often depends on how quickly you want results and how much of a time commitment you are able to make to the process.

Does Teeth Whitening Work on Every Type of Stain?
Whitening tends to be most effective on surface stains caused by coffee, tea, red wine, or smoking, since these sit closer to the outer layer of enamel. Discolouration caused by certain medications, injury, or issues within the tooth itself often responds far less predictably to standard whitening treatments.
This is why a dentist will usually examine your teeth before recommending whitening, since understanding the cause of discolouration helps set realistic expectations for the result.
Are Over the Counter Whitening Products Worth Using?
Whitening toothpaste and strips can offer a mild improvement over time, largely by removing surface stains rather than deeply altering the colour of the enamel. They are a reasonable option for very minor discolouration or for maintaining results after a professional treatment.
For more noticeable or long standing staining, professional whitening generally produces a faster and more dramatic result than store bought alternatives alone.

How Can You Make Whitening Results Last Longer?
Whitened teeth are more prone to picking up new staining in the days immediately following treatment, so avoiding strongly pigmented foods and drinks such as coffee, red wine, and dark sauces for a short period afterwards helps protect the result.
Ongoing good oral hygiene, along with occasional top up treatments if recommended by your dentist, are usually enough to keep results looking bright for a long time.

Frequently Asked Questions
Is professional teeth whitening safe for enamel?
Yes, when carried out under professional supervision at an appropriate concentration, whitening does not damage or weaken the structure of the enamel.
How long do whitening results typically last?
Results commonly last from several months up to a couple of years, depending on your diet, oral hygiene habits, and whether you smoke.
Can whitening help with yellow teeth versus grey teeth?
Whitening tends to be more effective on yellow toned discolouration than on greyish staining, which often has a different underlying cause.
Does teeth whitening cause sensitivity?
Some people experience temporary sensitivity during or shortly after treatment, which usually settles within a day or two once the whitening gel has fully cleared.
Can crowns or veneers be whitened along with natural teeth?
No, whitening gels only work on natural tooth enamel, so any crowns or veneers will not change shade and may need to be replaced separately to match whitened teeth.
