Sensitivity is the question almost everyone has before booking whitening and the one fewest people ask out loud. Usually it arrives phrased as “will it hurt”, and the answer it gets in most places is a reassurance rather than information.
Here is the information instead: what sensitivity is, who tends to get it, what can be done about it during the appointment, and what to raise at the consultation so it is discussed before rather than endured after.
What is actually happening
Whitening gel works through the enamel to change the shade of the tooth. That process can temporarily leave the tooth more responsive to temperature and touch than it usually is.
It is a common effect and it is usually temporary. It is not an indication that something has gone wrong, and it typically settles on its own without anything needing to be done.
Most people who experience it describe short, sharp twinges rather than a constant ache. Cold air on the way to the car is the classic trigger. Cold drinks are the other one. It tends to be intermittent, and it tends to reduce over the days after the appointment.
Sensitivity is common, usually temporary, and manageable during the appointment. It is not a reason to say nothing.
Who is more likely to experience it
Some patterns are worth knowing before you book.
Teeth that already react. If cold drinks already make you wince, that is the strongest single signal, and it is the first thing worth raising.
Gum recession. Where gums have receded, root surface is exposed. Root surface is not covered by enamel and is more responsive than the crown of the tooth.
Worn enamel. From grinding, from acidic diets, or simply from time.
Existing cracks or damage. Which is one of several reasons the consultation involves looking at your teeth rather than taking a booking.
Recent dental work. A reason to wait rather than a reason to proceed carefully.
None of these are automatically disqualifying. All of them change the conversation, and none of them can be assessed from a booking form.
Questions worth asking before you book
The title of this guide promises these, so here they are properly.
- My teeth already react to cold. Does that change whether I should do this?
- What can be adjusted during the appointment if I start feeling it?
- Is there anything you would suggest I do in the lead-up, given my history?
- How many cycles would you expect to do, and can that change on the day?
- What would you expect afterwards, and over what sort of period?
- At what point should I be contacting you rather than waiting it out?
- Is there anything about my teeth that means I should see a dentist first?
A clinic that answers those directly is giving you real information. A clinic that answers all of them with a reassurance is answering a different question. The guide on comparing clinics applies the same test to cosmetic work generally.
Note that the third one is deliberately phrased as a question rather than as advice. What is appropriate in the lead-up depends on your teeth and your history, and it is a decision made at your consultation rather than from a webpage.
The part that actually helps: speak up during it
This is the most useful paragraph on the page.
Whitening at Enrich Aesthetics is carried out in timed cycles. The gel is applied, activated with a light, removed, and reapplied. The number of cycles completed is a decision made as the appointment goes, not a fixed script that has to run to the end.
Which means if sensitivity starts at cycle three, the appointment can finish at cycle four instead of six. That is a normal adjustment, not a failed appointment.
The people who have a rough evening are almost always the people who said nothing at the time. There is no prize for getting through the full session, and the result from fewer cycles is a perfectly reasonable outcome, particularly given a top-up booked within 1 to 6 weeks of the initial treatment is available at a reduced rate.
Afterwards
Sensitivity after whitening is usually temporary and usually settles within a day or two, though it varies between individuals.
What to watch is the pattern rather than the presence. Sensitivity that is steadily reducing is doing what it usually does. Sensitivity that is getting worse, that is not settling, or that is concentrated in one particular tooth rather than spread across the mouth, is a different thing.
So is pain on biting, swelling, or a throbbing ache. Those patterns belong with a dentist, because they can point to something that was already there rather than to the whitening.
A cosmetic clinic does not diagnose dental problems, and being told to see a dentist is the correct answer rather than a deflection.
Why the consultation is not a formality
Every part of this is decided before the gel comes out.
At the consultation Kirsty checks your teeth and gums, asks about your sensitivity history, and identifies anyone who is not a suitable candidate. Untreated decay, gum disease and very recent dental work are all reasons to wait rather than to proceed carefully, and existing dental work at the front is the most common reason someone is not a candidate at all, since crowns, veneers, bonding and fillings do not change colour with whitening gel.
The full sequence of an appointment is set out in the in-chair whitening walkthrough, and pricing and options are on the service page.

The short version
Sensitivity during or after whitening is common, usually temporary, and generally described as short sharp twinges rather than a constant ache. Teeth that already react to cold are the ones most likely to notice it.
Raise your history at the consultation, ask what can be adjusted, and say something during the appointment if it starts, because the number of cycles is a decision rather than a script.
And if it is severe, worsening, or in one tooth only, that is a dentist’s question rather than a whitening one.
This guide is general education. It is not medical or dental advice, and it does not replace an in-person consultation.
