If you’re considering professional teeth whitening, one of the first questions you’ll probably ask is, “Does teeth whitening hurt?”
The good news is that for most people, professional teeth whitening is a comfortable treatment with little to no pain. While some patients may experience temporary tooth sensitivity, this is usually mild and disappears within a few days.
At Barnehurst Dentists, we provide safe, professional teeth whitening for patients across Barnehurst, Bexley, Bexleyheath, Welling, Sidcup and the surrounding areas, helping you achieve a brighter smile while keeping you comfortable throughout your treatment. Get in touch here to start the process.
Does Professional Teeth Whitening Hurt?
Professional teeth whitening should not be painful.
During treatment, most patients simply notice a slight tingling sensation or temporary sensitivity, particularly if they already have naturally sensitive teeth.
Unlike some over-the-counter whitening products, professional treatments are carefully monitored by your dentist and use high-quality whitening gels designed to minimise discomfort while delivering excellent results.
Why Can Teeth Feel Sensitive After Whitening?
Some patients experience temporary sensitivity because the whitening gel works by penetrating the enamel to lift stains from inside the tooth.
This process can briefly expose the tiny channels within the tooth, making it more responsive to hot or cold drinks.
This sensitivity is completely normal and usually settles within 24 to 48 hours, although some people may notice it for slightly longer. Read more about teeth whitening here.
Who Is More Likely to Experience Sensitivity?
You may be more likely to experience sensitivity if you:
- Already suffer from sensitive teeth
- Have worn enamel
- Have exposed tooth roots
- Have untreated tooth decay
- Have cracked teeth
- Have gum recession
Before starting treatment, we’ll examine your teeth to ensure whitening is suitable and address any underlying dental problems first.
How We Make Teeth Whitening More Comfortable
At Barnehurst Dentists, patient comfort is always our priority.
Before treatment we carry out a full dental examination to ensure your teeth and gums are healthy.

Professional whitening is significantly safer than buying unregulated products online.
Tips to Reduce Tooth Sensitivity After Whitening
If you do experience some temporary sensitivity, these simple steps can help.
Use Sensitive Toothpaste
Switch to a toothpaste designed for sensitive teeth a few days before and after treatment.
Avoid Very Hot or Cold Foods
Give your teeth a couple of days to settle by avoiding extreme temperatures.
Avoid Highly Acidic Foods
Foods and drinks such as citrus fruits, fizzy drinks and vinegar-based dressings can temporarily increase sensitivity.
Follow Your Dentist’s Instructions
Using whitening products for longer than recommended won’t produce better results but may increase sensitivity.
Is Professional Whitening Better Than Shop-Bought Kits?
Yes.
Many supermarket whitening products contain much lower levels of whitening ingredients, meaning they often produce limited results.
Some unregulated products purchased online can also damage your teeth or gums if used incorrectly.
Professional whitening provides:
- Safer treatment
- Better whitening results
- Longer-lasting improvements
- Supervision by a qualified dentist
- Personalised advice
How Long Does Teeth Whitening Last?
Professional whitening results typically last between one and three years, depending on your lifestyle.
Results often last longer if you:
- Brush twice daily
- Attend regular dental check-ups
- Avoid smoking
- Limit tea, coffee and red wine
- Use your whitening top-up trays when recommended
Is Teeth Whitening Safe?
Yes.
When carried out by a qualified dental professional, teeth whitening is considered a safe and effective cosmetic treatment.
Before whitening begins, your dentist will assess your oral health to make sure treatment is appropriate and discuss the results you can realistically expect.
FAQs
Does teeth whitening damage enamel?
No. Professional whitening does not damage healthy tooth enamel when carried out correctly.
How long does sensitivity last?
Most sensitivity disappears within 24 to 48 hours.
Can I whiten sensitive teeth?
Yes, in many cases. We’ll assess your teeth first and recommend the safest approach for you.

Not always. Whitening isn’t suitable for everyone, which is why a dental examination is essential before treatment.

Most patients find laser whitening comfortable, with only mild temporary sensitivity afterwards.

Yes, although we recommend avoiding foods and drinks that may stain your teeth for the first 24 to 48 hours.
