Teeth whitening for sensitive teeth
Whitening teeth is an increasingly popular aesthetic dental treatment. It's an effective process that removes surface stains from teeth and reduces the appearance of discolouration. Despite the benefits, it's not uncommon to come away with sensitive teeth in the days after the treatment.
This can be a factor in not choosing to go ahead for some people, particularly if they already have teeth sensitivities.
Why is in-clinic teeth whitening better?
In-office teeth whitening procedures are more efficient than using whitening products bought online or over-the-counter whitening gels and bleaching agents, as they use a higher concentration of peroxide, and the process is conducted by a trained aesthetic orthodontist. This is an important consideration if you're researching where to get your teeth whitened.

What causes teeth whitening sensitivity?
Around 1 in 3 of us struggle with tooth sensitivity, and the reasons can vary widely. From thin, or damaged tooth enamel to sensitivity after an orthodontic treatment, or extreme temperatures in foods and drinks.
Dental sensitivity can occur as a result of temporary or more enduring factors, but there is one particular sensitivity that dental professionals often get asked about - dental pain after in-clinic whitening agents.
Pain from whitening your teeth
Teeth whitening sensitivity is specifically related to feelings of short, sharp bouts of pain in the teeth and gums after your whitening treatment.
The reason for teeth whitening sensitivity is due to the hydrogen peroxide or carbamide peroxide used on the teeth as it soaks through your teeth enamel, exposing the nerves in your dentine.
Is it normal for teeth to be sensitive after whitening?
While it's completely normal for patients who have teeth whitening treatments to experience sensitive teeth after the whitening treatment, it's important to understand the normal levels of sensitivity and ways to reduce sensitivity as well.
Before a whitening treatment
There are several things you can try before your whitening treatment to prepare for the best outcome and minimise any pain afterwards.
- Book a consultation appointment with a trusted dentist to discuss the best course of treatment for you.
- Book the treatment with a known and reputable provider.
- Use a desensitising toothpaste the week before treatment.
- Stop using any other teeth whitening products, such as low-dose bleaching gel, or toothpastes with active ingredients for whitening in them.
